The fifth-generation Ford Mustang is a pony car manufactured by the Ford Motor Company. The fifth generation began with the 2005 model year, and received a facelift in 2010. In 2011, the Mustang received engine upgrades. It is manufactured at the AutoAlliance International plant in Flat Rock, Michigan. Originally designed by Sid Ramnarace, the fifth-generation Mustang's design was based on two preproduction concept cars that first debuted at the 2003 North American International Auto Show. Since its introduction, there have been several variants of the fifth-generation Ford Mustang produced including the Mustang GT/California Special, Shelby Mustang, Bullitt Mustang, and Boss 302 Mustang.

Preproduction concepts

The fifth-generation Mustang convertible concept

Two preproduction concept cars, a convertible and coupe model, were originally presented by Ford at the 2003 North American International Auto Show on January 5, 2003.^[1][2]

The Redline Red Metallic Ford Mustang GT convertible concept included a "showbar" with a rim of billet-aluminum trim, 20-inch wheels, 13.8-in cross-drilled Brembo brakes, red and charcoal leather upholstery with perforated surfaces on the seat backs, billet-aluminum shifter for the 5-speed automatic transmission, 4-point racing-style seatbelts and unique instrument gauges.^[3]

The Tungsten Silver Ford Mustang GT coupe concept included a glass roof and lush red and charcoal leather interior accented by billet-aluminum hardware, functional hood scoops, supercharged MOD 4.6L engine rated nearly 400 horsepower.^[4]

Appearing with other concept vehicles at the show such as the Cadillac Sixteen, Aston Martin V8 Vantage, and Dodge Tomahawk, AutoWeek called the concept the "most significant vehicle in show".^[5]

Both vehicles were eventually sold at the 2009 Barrett-Jackson Palm Beach auction for the winning bid price of $175,000 USD each (before buyer premium).

At the following year's North American International Auto Show, Ford introduced a completely redesigned Mustang based on the 2003 concept vehicles which was codenamed "S-197". Its platform was an all-new D2C platform for the 2005 model year. Developed under the direction of Chief Engineer Hau Thai-Tang and exterior styling designer Sid Ramnarace, the fifth generation Mustang drew inspiration from Mustangs of the 1960s, notably the 1967–68 models. It was this redesigned aesthetic that inspired Ford's Senior Vice President of Design, J Mays, to call it "retro-futurism." The 2005 Mustang's unique retro coupé styling complements its muscle car status with an approximate weight-to-power ratio of 11.5:1 in GT form.

Mustang

2005–2009 Ford Mustang V6 convertible

The 2005–2009 base Mustang is powered by Ford's cast iron block 4.0 L Cologne SOHC V6, replacing the 3.8 L Essex OHV V6 used in 2004 and older models. It produces 210 hp (157 kW) at 5300 rpm and 240 lb·ft (325 N·m) of torque at 3500 rpm and is mated to a standard Tremec T-5 5-speed manual transmission with Ford's 5R55S 5-speed automatic transmission available as an option. A 3.31:1 final drive ratio is standard with either transmission. Though criticized for a lack of refinement, the standard V6 powertrain is capable of delivering competitive performance. In a comparison test with a Pontiac G6 Convertible conducted by Motor Trend magazine, a Mustang V6 Convertible equipped with an automatic transmission was able to accelerate from zero to 60 miles per hour (97 km/h) in 7.3 seconds; 1.4 seconds better than its competitor.^[6] All models of the current Mustang make use of an independent MacPherson-strut front suspension with reverse "L" lower control arms. The rear suspension utilizes a new three-link system with a Panhard Rod which controls the vertical and lateral movements of the axle.^[7] This live axle rear suspension, while sacrificing handling, provides the benefits of reduced cost and weight over heavier, more expensive independent rear suspensions. In spite of this, Ford has drawn heavy criticism from the automotive journalism community for the decision to equip the current Mustang with the live axle system. At a press conference, Ford stated that to include an independent rear suspension would have added $5,000 to the showroom price of the car.

Some of the standard features that the 2005 Mustang launched with include power windows, dual power mirrors, power door locks with remote keyless entry, front air bags, AM/FM stereo with CD player, 16-inch painted aluminum wheels, and larger brake discs than the previous generation Mustang with twin-piston calipers in the front. Some of the options available included Ford's MyColor (a color-configurable instrument cluster available as part of the Interior Upgrade Package), brushed aluminum panels (also part of the Interior Upgrade Package), Ford's Shaker 500 (500 watt peak output) or Shaker 1000 (1000 watt peak output) premium audio system with a 6-disc MP3-compatible CD changer, leather seating surfaces, a six-way power adjustable driver seat, and a four-channel anti-lock brake system with traction control (standard on GT models).^[8]

As of 2008, all Mustangs have seats containing material derived from soy beans,^[9] harking back to some of Henry Ford's ideals.

Ford Sync was available on the 2009 model only as a dealer-installed kit.

Several new options and standard features were introduced in the following years, including the Pony Package (2006; see below), a DVD-based GPS navigation system made by Pioneer (2007, late availability), a power passenger seat (2007), heated seats (2007), Sirius Satellite Radio (2007), standard side airbags (2008), HID headlamps (2008), and ambient interior lighting (2008), in addition to a variety of new wheel styles and exterior paint colors.

For 2009, Ford introduced a new option called the glass roof. This option ($1,995 at introduction) is in effect a full roof sunroof that splits the difference in price and purpose of the coupe and convertible models.^{[10][dead link]}

Pony Package

2007 Ford Mustang V6 coupe with Pony Package

The Pony Package for the V6 Mustang became available starting in 2006. This option includes an upgraded suspension derived from the Mustang GT, 17-inch wheels with wider tires (originally only available on the GT), a unique grille design with fog lamps, a rear deck spoiler, and unique door striping and emblems.^[11]

V6 Appearance Package

At the 2007 SEMA show in Las Vegas, Ford Custom Accessories introduced the V6 Appearance Package to the world. Introduced as a Mustang one can order with equal parts excitement and exclusivity, the V6 Appearance package hearkens back to the 60s styling of Mustang with a Billet grille, scoops, a spoiler and black-out treatment designed to give this Mustang an aggressive look. The V6 Appearance Package is a factory package that includes a chrome billet-style upper grille, body color side scoops, black satin front lip spoiler, black satin hood stripe, GT hood scoop, bright rolled exhaust tips, GT black rear spoiler, unique black satin decklid applique, upgraded black floor mats, and 18-inch premium polished forged aluminum wheels.^[12] Available in 2008 as a $2,398 option, this package was encouraged to be applied with Ford Racing goodies including the Ford Racing Power Pack FR1 (which includes a 85 mm Cold Air Intake sourced from the Bullitt, True Dual exhaust with a X-pipe and Bullitt Mufflers, a Pro-Cal Hand held tuner and a Ford Racing Performance oil filter), the Ford Racing Handling Package FR3 (which includes shocks/struts, front and rear anti-rollbars, V6 lowering springs, and a V6 Strut Tower Bar) and the Ford Racing Short Throw Shifter. Available in 2008 using the V6 Appearance Package was only available when one ordered the V6 Coupe with the Premium Package with either an automatic or manual transmission and only with Grabber Orange, Vapor Silver Metallic, and Dark Candy Apple Red.^[13] For 2009 everything remained pretty much the same except that the V6 Appearance Package was offered additionally in Performance White and Black. According to the 2008 Mustang Take Rate Report, 152 V6 Appearance Packages were built and according to the 2009 Mustang Take Rate Report 96 were built.^[14][15]

Mustang GT

2005–2009 Ford Mustang GT convertible

The Mustang GT features an all-aluminum 4.6 L 3-valve SOHC Modular V8 with variable camshaft timing and a more rugged Tremec TR-3650 transmission. The engine produces 300 hp (224 kW) @ 5750 rpm and 320 lb·ft (433 N·m) of torque @ 4500 rpm. The GT model is capable under some circumstances of performing a quarter-mile test in 13.5 seconds, with acceleration from zero to 60 MPH in 4.9 seconds.^[16] The current Mustang GT also comes equipped with a limited slip differential complete with the same carbon-fiber clutch discs used in the 2003 to 2004 SVT Cobra and the 2007 Shelby GT500. The differential is designed for the 31-spline axles and the 8.8 in (224 mm) ring gear. The standard final drive ratio of 2005 and 2006 Mustang GTs with a manual transmission is 3.55:1. Since the 2007 model year, a 3.31:1 ratio final drive is standard with the 3.55:1 gearing available as a factory installed option. Automatic transmission-equipped models of all years receive the less aggressive 3.31:1 ratio.

The Mustang GT builds on the base Mustang's standard features. In addition to its higher performance powertrain, the Mustang GT features a stiffer, better handling version of the standard suspension, larger 12.4-inch front brake discs (versus the 11.4-inch discs used on V6 Mustangs), standard four-channel ABS with traction control, a two-piece drive shaft, a stainless steel dual exhaust, standard grille-mounted fog lights, and 17-inch wheels with optional 18-inch wheels.

GT California Special

2007 Ford Mustang GT/CS

In 2007, Ford introduced the GT California Special (GT/CS) package, hearkening back to the original 1968 California Special Mustang. The package adds 18" polished aluminum wheels, non-functional side scoops, and unique vinyl striping. The GT/CS also includes a different front fascia and rear valance with diffuser, similar to those found on the Shelby GT. The GT/CS edition's front fascia is 1.5 inches lower to the ground than the standard GT. Interior upgrades include Mustang labeled floor mats, and CS only leather interior color options. The 2007 GT Appearance Package adds a hood scoop, exhaust tips and engine cover.

In 2011 The GT California Special again returned for the Five liter Mustang GT. The 5.0 emblem is again absent in favor of the black GTCS side stripes which fade into a side scoop. The front fascia is replaced with the one used in the 2011 Boss 302 with working lower fascia fog lights. The rear diffuser is now taken from the Shelby GT 500 while the rear deck lid gets black vinyl and a wing spoiler completes the look. Wheels are upgraded to 19 inch 10 spoke argent color with a GT stamped towards the outer rim on each wheel. The interiors bright dash is replaced with black carbon fiber treatment while carbon fiber door inserts and seat leather patterns complete the look. Badging includes "GTCS" on the carbon fiber dash and floor mats. The front Grill is brushed aluminum billet with a V6 style pony emblem on the drivers side. (for 2012 It's changed to black billet) While the Brembo brake package is not available with the California special (402A), it can still be ordered with choice of gears (3.31, 3.55, or 3.73) from the factory.

2008–2009 Bullitt

2008 Ford Mustang Bullitt

The Mustang Bullitt returned in February 2008, a special edition variant of the Mustang GT, the last version of which was produced in 2001. The 2008 Bullitt is reminiscent of the Dark Highland Green GT-390 fastback Mustang driven by Steve McQueen in the 1968 film of the same name. Available in Dark Highland Green or Black exterior paint and is stripped of its spoiler and GT fender emblems; the faux gas cap on the deck lid is replaced by a unique Bullitt version. The Mustang GT's standard fog light-equipped grille is replaced with the base V6 style grille without the running horse logo. Dark Argent Gray 18-inch cast-aluminum wheels are used with matching brake calipers and larger, 3.5 inch exhaust tips to replace the Mustang GT's standard 2.5 inch tips. Starting MSRP of $31,075, this model was not sold with side (quarter) window louvers, as shown in this picture. However, the side louvers are a common addition among owners since it is also similar to the 1968 Mustang fastback.

The Mustang Bullitt is powered by an enhanced version of the Mustang GT's aluminum 4.6 L SOHC V8. Additional power is added through the use of a unique cold air intake, improved engine calibration, and a revised exhaust system specifically designed to mimic the sound of the Mustang used in the Bullitt movie. Total output is 315 hp (235 kW) @ 6000 rpm and 325 lb·ft (440 N·m) of torque @ 4250 rpm and the engine's redline has been raised to 6500 rpm (from the standard Mustang GT's 6250 rpm). Premium grade, 91-octane or better gasoline is recommended for the Bullitt's V8 for top performance but, significantly, an adaptive spark ignition system allows the engine to accept regular grade gasoline without any adverse effects. Total output is the same with either fuel but the engine delivers a flatter torque curve when using premium. The same Tremec TR3650 5-speed manual transmission from the Mustang GT is used in the Mustang Bullitt but the Bullitt features a more aggressive 3.73:1 rear axle ratio (versus the Mustang GT's 3.31:1 or optional 3:55:1 ratios). The Bullitt's suspension is improved over the standard GT utilizing stiffer springs, struts, and a decorative front strut tower brace while also lowering the car's ride height by six millimeters.^[17] All of the Mustang Bullitt's unique components are available in the aftermarket for retrofitting earlier S197 Mustang GT vehicles but the parts used in Bullitt Mustangs are marked to show their authenticity.

According to the 2009 Mustang catalog, the Bullitt package was available on manual transmission Mustang GT Premium coupes as a regular production option; the same color restrictions apply.

45th Anniversary Edition (2009 GT)

2009 Mustang GT 45th Anniversary Badge

2009 Mustang GT 45th Anniversary Edition (with custom quarter window louvers)

Special features of the 2009 Mustang include a new glass top roof option as well as special 45th Anniversary badging to commemorate the 45th anniversary of the Ford Mustang's launch on April 17, 1964. Ford reports state that only 45,000 units will be sold for the model year, although by the end of production a total of 46,420 were built.^[18] Satellite Radio becomes standard on all premium interior models, and Deluxe is no longer used to identify base models. This model has the same engine and functional equipment as a basic GT. The 2009 45th Anniversary edition is badged with a Mustang Colt emblem, with the 45th Anniversary logo. It comes with a hood scoop, rear spoiler, the Ambient Lighting package, and 18" polished aluminum wheels.

Iacocca Silver 45th Anniversary Edition (2009½ GT)

Main article: Ford Mustang variants

2009½ Iacocca Mustang

The Iacocca Silver 45th Anniversary Edition is a limited (45 unit) edition commemorating the 45th anniversary of Ford Mustang. It is based on the 2009 Mustang platform, and was designed by Michael Leone and built by California-based Gaffoglio Family Metalcrafters coachbuilding company. Despite the build status, it still carries factory engine and Ford Racing Package warranties. Lee Iacocca was given car 1 of 45. One was sold for $352,000 at auction.^[19]

Shelby GT and GT-H

2006's Shelby GT-H and later Shelby GT, based on the standard GT model, is modified by Carroll Shelby International to produce 319 hp (238 kW) by means of a Ford Racing air intake, performance tune, and upgraded exhaust system.^[20]

The Shelby GT-H, made available for rent only at selected Hertz car rental outlets, traces its roots to the original 1966 Shelby GT350H, famously known as the "Rent-A-Racer". The GT-H appears only in black exterior paint and twin gold racing stripes as a nod to the Hertz company's history. Completing the unique visual treatment is a billet aluminum grille, custom Shelby hood with functional hood pins, and the same front and rear fascia that would be found on the later Shelby GT and GT/CS models. The GT-H is outfitted with a Ford Racing Power Pack which includes a cold air intake, a revised exhaust system and custom performance calibration, boosting power to 319 hp (238 kW) and torque to 330 lb·ft (447 N·m). The GT-H also includes the Ford Racing Handling Pack with lowering springs, improved dampers, sway bars, a strut tower brace and a 3.55:1 ratio rear axle assembly.^[21] 500 units of the coupe model were created for the 2006 model year, and a second run of 500 convertible models has been announced for 2008.^[22]

Shelby GT500

Main article: Shelby Mustang

Shelby GT500

For 2007, Ford's Special Vehicle Team launched the highly anticipated Shelby GT500, successor to the 2003/2004 Mustang SVT Cobra. The GT500 shares many of its basic design characteristics with that of the Mustang V6 and GT. In particular, the GT500 retains the same basic live axle rear suspension setup of the Mustang V6 and GT, with some minor durability enhancements to handle the car's power. Thicker sheetmetal supports and extra welds can be found on the GT500 chassis as well as redesigned strut towers to accommodate a wider engine. A supercharged 5.4 L 32-valve DOHC V8 with an iron block and aluminum heads powers the GT500. The engine is mated to a Tremec TR6060 6-speed manual transmission and is rated to produce 500 hp (373 kW) @ 6000 rpm and 480 lb·ft (650 N·m) of torque @ 4500 rpm. A final drive ratio of 3.31:1 is standard in the GT500. Also standard are 18×9.5 inch wheels with P255/45ZR18 tires in the front and P285/40ZR18 tires in the rear. Stopping is provided by Brembo 14-inch disc brakes with aluminum four-piston calipers in the front and 11.8-inch disc brakes with two-piston calipers in the rear.^[23]

The GT500 failed to meet some automotive journalist's expectations.^[24][25] Car and Driver magazine, for example, though praising the GT500 for its ample horsepower and relatively smooth ride, criticized their test car for its heavy weight and, in particular, the nose-heavy weight distribution of 57.7% front and 42.3% rear (compared to the 52.5% front, 47.5% rear of a Mustang GT manual they tested).^[26] Nevertheless, in spite of their opinion of its drawbacks, Car and Driver drove a GT500 in their 2007 "Lightning Lap" road test at Virginia International Raceway and found that the car's on-track performance lap time of 3:05.9 fell just below that of the Porsche 911 Turbo (3:05.8) and faster than that of the Lotus Elise (3:09.3), Porsche Cayman S (3:09.5) and BMW M6 (3:10.0).^[27]

Shelby GT500KR

Debuting as a 2008 model, the Shelby GT500KR, "KR" being an abbreviation for "King of the Road", pays homage to the original 1968 Shelby Mustang of the same name. The GT500KR, with a MSRP of $79,995, features new components and performance enhancements over a standard GT500. Under the hood, the GT500KR uses the same supercharged 5.4 L DOHC V8 as the standard GT500, but the KR's engine has been tuned to make 540 hp (403 kW) @ 6250 rpm and 510 lb·ft (691 N·m) of torque @ 4500 rpm, gains of 40 hp and 30 lb·ft of torque, respectively. While the Tremec TR6060 6-speed manual transmission remains the same, the GT500KR also benefits from a more aggressive 3.73:1 final drive ratio. To improve handling and help offset the car's front-heavy weight distribution, the GT500KR features a Ford Racing strut tower brace and uniquely tuned struts, shocks, and springs. Finally, to maximize the GT500KR's performance gains, measures were taken to keep the car's weight in check. Through the use of a carbon fiber hood and a revised exhaust system, the overall weight of the GT500KR is 22 lbs lighter than a standard GT500.^[28]

Mustang

2010 Ford Mustang GT coupe

The 2010 model year Mustang was unveiled on November 18, 2008, prior to the Los Angeles International Auto Show. It went on sale in the spring of 2009. The 2010 Mustang is a revision of the 2005–2009 models, remaining on the D2C platform. Chief designer Doug Gaffka was previously responsible for the 2008–2009 Bullitt and other Ford vehicles. The new Mustang's exterior is sculpted for a leaner, more muscular appearance. Better aerodynamic performance (coefficient of drag by 4% on V6 models and 7% on GT models^[29]). Specific changes to the exterior include a restyled Mustang emblem, a new headlight design with integrated turn signals, new slimmer side mirror design (they're now also color keyed in GT trim), a prominent powerdome hood to complement the car's muscular exterior, and revised three-lens taillights with LEDs that blink in sequence for turn indication. Additionally, the 2010 Mustang GT uses smaller fog lights than the 2005–2009 models though they are still mounted in the car's grille. Fog lights on V6 models (a part of a revised Pony Package first introduced for 2006) are now mounted in the lower fascia below the grille. In all models, the radio antenna has been moved to the rear of the car and the lock for the trunk no longer features a keyhole on the trunk lid, substituting with a remote trunk release only.^[30] In spite of its changes, the 2010 Mustang's overall exterior dimensions are nearly identical to the 2005–2009 models.^[31]

The Mustang's interior was revised featuring higher quality thermoplastic olefin surfaces, available real aluminium trim, and improved fit and finish. The new design moved away from the linear nature of the previous models. Gary Morales, Design Manager for the 2010 Mustang, said about the attention to detail paid to the Mustang's new interior, "We never stopped at, 'Good enough.' We only stopped at 'right.'"^[32] Ford SYNC is available on all trim levels of the present Mustang except the base model.

The standard engine is a 4.0 L V6 mated to a 5-speed manual transmission or an optional 5-speed automatic transmission. The V6 powertrains are unchanged from those used in 2005–2009 Mustangs. Though the 2010 Mustang retains a single exhaust outlet, the diameter of the tip has been increased one-half of an inch to three inches.^[33] The 2010 Mustang includes new spring rates and dampers to improve ride quality and control and Ford's AdvanceTrac traction and stability control system standard. Newly standard on the base Mustang are 17-inch painted aluminum wheels while 18-inch wheels continue to be optional (except for V8 models, where 18-inch wheels are mounted by default). Other new available features and options for the 2010 Mustang included Ford SYNC, dual-zone automatic climate control, an updated navigation system with Sirius Travel Link, a capless fuel filler, a reverse camera system to aid in backing up, and an updated version of the V6 Pony Package.^[31]

New powertrains for 2011 replaced the aging 4.0 L V6 used in the Mustang since the 2005 model year. These include Ford's Duratec 37 3.7 L DOHC V6. Unlike earlier versions of the engine, the 2011 Mustang features Twin-independent Variable Cam Timing (Ti-VCT). The new V6 now has true dual exhaust, compared to the single outlet exhaust that the previous 4.0 L V6 – the engine is rated to produce 305 bhp (227 kW) @ 6500rpm and 280 lb·ft (380 N·m) of torque @ 4250rpm.^[34]

The 2011 Mustang is also capable of achieving good fuel efficiency due in part to also-new transmissions. With the newly standard Getrag MT82 6-speed manual transmission co-developed with Ford, the 2011 Mustang has been rated by the EPA to achieve 19 mpg_-US (12 L/100 km; 23 mpg_-imp) in city driving and 29 mpg_-US (8.1 L/100 km; 35 mpg_-imp) on the highway. The newly optional Ford 6R60 6-speed automatic achieves 19 mpg_-US (12 L/100 km; 23 mpg_-imp) in city and 31 mpg_-US (7.6 L/100 km; 37 mpg_-imp) on the highway.^[35] The a newly standard 2.73:1 limited slip rear axle is more fuel efficient compared to the more aggressive 3.31:1 axle used previously. The 3.31:1 axle remains available in the 2011 Mustang as a performance option.^[34]

The 2011 Mustang offered a V6 Performance Package starting in summer 2010. The package features a standard 3.31:1 rear axle, stiffer suspension tuning, 19-inch wheels with performance tires, a strut tower brace, and performance-oriented electronic stability control calibration.^[34]

Other, non-powertrain related upgrades made to the 2011 Mustang include Electric Power Assist Steering (EPAS) with pull-drift compensation and active nibble control, general aerodynamic and NVH improvements over the 2010 Mustang, a digital message/information center, blind spot mirrors integrated into the car's side mirrors, a universal garage door opener, a 160 mph speedometer, and Ford's MyKey programmable vehicle key technology.^[34]

Mustang GT

The 2010 Mustang GT adds a more powerful version of the 4.6 L V8 seen in 2005–2009 Mustang GTs. The 2010 Mustang GT's revised V8 produces 315 bhp (235 kW) @ 6000rpm and 325 lb·ft (441 N·m) of torque @ 4250rpm. The 5-speed manual and automatic transmissions offered with the updated V8 continue unchanged from before. The size of the 2010 Mustang GT's dual exhaust tips has been increased by one-half of an inch to 3.5 inches while the exhaust note has been improved to enhance the sound of the V8.^[33] Like the base V6-equipped Mustang, the 2010 Mustang GT includes new spring rates and dampers to improve ride quality and control. AdvanceTrac is also standard in the Mustang GT though a special Sport Mode setting is added for spirited driving. The 2010 Mustang GT comes with standard 18-inch wheels – one inch greater than the previous Mustang GT's standard wheels – while 19-inch wheels are a new option.^[31]

Newly available for the Mustang GT for 2010 are two performance packages. The 3.73 Axle Package features higher performance front brake pads, a more aggressive 3.73:1 rear axle, and a recalibrated AdvanceTrac system. The Track Package features higher performance front and rear brake pads, stabilizer bars and rear lower control arms from the GT500, uniquely tuned shocks and struts, Pirelli summer tires (includes automatic upgrade to 19-inch wheels), a 3.73:1 rear axle with carbon plates in the differential, and a recalibrated AdvanceTrac system.^[29][36]

A V8 engine is available for 2011, complete with new transmissions and other upgrades. The Mustang GT's new engine is an all-aluminum 32-valve 5.0 L DOHC V8, codenamed Coyote. The 2011 Mustang GT marks the engine's first use in any production vehicle. While the new engine's displacement is similar to Ford's original "5.0" 4.9 L (302 cu in) V8, it is an unrelated design and instead shares more in common with the 4.6 L V8 and other Modular engines that it replaces. The new 5.0 uses a DOHC head design like other Modular engines and even shares its bore spacing and deck height with the outgoing 4.6 L V8. Differing the new engine from earlier Modular engines, among other features, is its use of wider bore diameters (and a longer stroke relative to the 4.6 L V8 in particular), to allow the use of larger valves, and camshaft torque-actuated Twin-independent Variable Cam Timing (Ti-VCT). In spite of its more advanced design, the new engine weighs in at approximately 430 lb (195 kg) – about 10 lb (5 kg) heavier than the Mustang GT's previous 4.6 L V8. Red-line has been raised to 7,000 rpm. Using premium grade, 91-octane or better gasoline, the new 5.0 L V8 can produce 412 bhp (307 kW) @ 6500rpm and 390 lb·ft (529 N·m) of torque @ 4250rpm.^[37] Output of the 5.0 drops to 402 bhp (300 kW) @ 6500rpm and 377 lb·ft (511 N·m) of torque @ 4250rpm when regular grade gasoline is used.^[38]

Two noteworthy improvements the 5.0 engineers had to fight with the bean counters over included piston cooling oil jets which both warm the engine up faster and keep it running cooler, and ford racing style tubular performance headers. The water/coolant and oil flow patterns were heavily optimized for proper flow under high lateral forces such as on a race circuit. Budget restrictions prevented the use of an optional racing oil cooler and Direct Injection (DI) but the engine is designed such that both can easily be added to future Mustangs. In the case of the oil cooler....possibly even as an after market add on.

Like the updated V6 Mustang, the Mustang GT also gets new transmissions for 2011. Both transmissions are heavier duty versions of the same designs offered with the V6 Mustang; a Getrag/Ford MT82 6-speed manual transmission and Ford's 6R80 6-speed automatic transmission. The 6-speed manual transmission comes with a 3.31:1 rear axle while 6-speed automatics get a taller 3.15:1 rear axle. Combined with its new, more efficient V8, the new 6-speed transmissions contribute to an improvement in fuel economy in the 2011 Mustang GT over its counterpart from the 2010 model year. As certified by the EPA, manual transmission models are able to achieve 17 mpg_-US (14 L/100 km; 20 mpg_-imp) in city and 26 mpg_-US (9.0 L/100 km; 31 mpg_-imp) on the highway while automatic transmission models are able to achieve 18 mpg_-US (13 L/100 km; 22 mpg_-imp) in city and 25 mpg_-US (9.4 L/100 km; 30 mpg_-imp) on the highway.^[39]

The Mustang GT gains the same non-powertrain related upgrades that standard V6 Mustangs get for 2011. Other, new features exclusive to the 2011 Mustang GT include "5.0" fender badges replacing the "GT" badges used previously, an optional Brembo Brake Package taken from the Shelby GT500 (comes with unique 19-inch wheels), and suspension enhancements. Convertible versions of the Mustang GT in particular received a front strut tower brace, stiffened crossmembers, and other enhancements resulting in a 12% increase in structural rigidity compared to 2010 Mustang GT convertibles. All 2011 Mustang GT's with 19 inch wheels (brembo brake equipped, california special, etc.) also get the strut tower brace and stiffened cross members.

Taller rear head rests have been added for whip-lash protection, with fold down feature for visibility when rear passengers are not present. The rear fascia is altered for slightly better aerodynamics from the 2010 as well.^[37]

Shelby GT500

Main article: Shelby Mustang

2010 Shelby GT500

The 2010 Shelby GT500 was revealed by Ford through a press release on January 1, 2009 as a precursor to a public unveiling at the 2009 North American International Auto Show. As before, many of the basic design characteristics of the new GT500 are shared with that of the Mustang and Mustang GT. In particular, the GT500 gains the same exterior and interior updates as the 2010 Mustang and Mustang GT. Differentiating it from the Mustang and Mustang GT on the outside, however, is a unique front fascia with larger upper and lower grilles, a unique hood, large fog lights mounted in the lower front fascia (similar to the previous GT500), Shelby's signature cobra badges on the grille, front fenders, and trunk lid medallion (with Shelby lettering over the medallion), unique 19-inch wheels (18-inch on the convertible model), and a unique Gurney Flap rear spoiler. Inside the GT500, a unique cobra disc on the steering wheel, shift ball, and seats with embroidered cobras are the only major elements that differ it from the Mustang and Mustang GT.^[40]

Mechanically the 2010 Shelby GT500 remains closely related to the 2007–2009 GT500, but the 2010 model has been upgraded with various features similar to or found in the 2008 Shelby GT500KR. A conical cold air intake and other enhancements to the GT500's supercharged 5.4 L DOHC V8 have resulted in an increase in output to 540 bhp (400 kW)@6200rpm and 510 lb·ft (691 N·m)@4500rpm, gains of 40 hp and 30 lb·ft of torque over the 2007–2009 GT500 respectively. The Tremec TR-6060 6-speed manual transmission returns for the 2010 GT500 but has been enhanced with larger clutch discs (250 mm (9.8 in) versus the 215 mm (8.5 in) discs used previously) and other measures to increase performance and noise, vibration, and harshness (NVH) control. Additionally, the fifth and sixth gear ratios of the transmission have been changed from 0.80 to 0.74 and 0.63 to 0.50 respectively, contributing to an improvement in fuel efficiency that the 2010 GT500 enjoys over its predecessor. Complementing the transmission's gear ratio changes is a new, more aggressive 3.55:1 ratio rear axle which replaces the 3.31:1 axle used previously. And According to Inside Line driver's of the new 2010 Shelby can expect 0 to 60 times in 4.3 seconds from a stand still and 4 seconds flat with roll out. Elsewhere, the GT500's aluminum hood, in addition to be stylistically different from that of the Mustang and Mustang GT, features an air extractor that helps cool the engine. Various aerodynamic upgrades, such as the design of the front fascia and the aforementioned Gurney Flap spoiler, contribute to increased downward force and a reduced coefficient of drag. Suspension enhancements found in the GT500KR are used in the 2010 GT500 to improve handling and, specifically, provide better roll control. The 2010 GT500 features Ford's AdvanceTrac traction and stability control system standard with different settings to control the level of performance the driver desires.^[40]

The 2010 Shelby GT500 was released in the spring of 2009.

For 2011, the Shelby GT500 received significant performance enhancements and other upgrades. Arguably the most important of the GT500's upgrades is a new aluminum engine block for the car's supercharged 5.4 L DOHC V8, replacing the cast-iron block used previously. The block's cylinder bores are coated with an iron and iron oxide composite that is applied with Plasma Transferred Wire Arc (PTWA) technology, which was developed jointly by Ford and Flamespray Industries (www.flame-spray.com). The developers of PTWA received the IPO 2009 National Inventor of the Year award. The coating allows for the replacement of traditional cast-iron cylinder liners and marks Ford's first use of this process. Between this and the use of lighter-weight aluminum for the engine block, the new block is 102 lbs lighter than the previous cast-iron version, contributing to a reduction in the overall weight of the GT500 compared to the 2010 model. Thanks to the new liner coating, which has friction-reducing characteristics, and a revised exhaust, horsepower production from the 5.4 L V8 has increased slightly for a total of 550 bhp (410 kW)@6200rpm. The combination of the lighter engine, EPAS, and aerodynamic enhancements result in an improvement in fuel efficiency for the 2011 GT500 relative to the 2010 model that eliminates the car's gas guzzler tax.^[41]

Maximizing the performance potential of the lighter and more powerful 2011 GT500, a newly optional SVT Performance Package will be available. The package includes a more aggressive 3.73:1 rear axle, Goodyear Eagle F1 SuperCar G:2 tires, 19-inch wheels in the front and 20-inch wheels in the rear (all four are made of forged aluminum), and firmer suspension tuning.^[42]

The Shelby GT500 gains the same non-powertrain related upgrades that standard V6 Mustangs and Mustang GTs get for 2011. Other new features for the GT500 for 2011 include standard HID headlights and a glass roof option.^[41]

Pricing ranges from $22,125 MSRP for the 2011 basic V6 Coupe to $48,645 MSRP for the 2011 Shelby GT500.
