Mondeo V6 Manufacturer Ford Motor Company Production 1994–present Predecessor Ford Vulcan
Mazda K seriesSuccessor Ford Cyclone Displacement 2.5 L (2544 cc) – 3.0 L (2967 cc) Ford Motor Company's modern 2.5 L and 3.0 L V6 automobile engines are evolutions of the same design, first used in the 1994 Ford Mondeo. This line is sold under the brand name "Duratec", as are many other engines.
The Mondeo V6 is a modern aluminum DOHC V6 with a 60° bank angle. The primary engineering input came from Porsche, who were developing a similar V6 before selling the engineering to Ford, and Cosworth, who helped with cylinder head manufacturing.[citation needed] The Jaguar AJ-V6 engine is similar but adds variable valve timing. Mazda's AJ version also has this feature.[citation needed]

Duratec 25
The Duratec 25 is a 2.5 L (2544 cc) 60° V6 and was introduced in 1994. It was developed for the Ford Mondeo and also used in the Ford Contour and others. Bore is 82.4 mm (3.2 in) and stroke is 79.5 mm (3.1 in).
The Duratec 25 was on the Ward's 10 Best Engines list for 1995 and 1996, and the SVT version made the list for 1998 and 1999.
Duratec 25 SVT
An SVT version produced 195 hp (145 kW) and 165 ft·lbf (224 N·m) in 1998. It included a larger throttle body from the Duratec 30, a new cone-shaped air filter, and abrasive flow machining processing on the intake manifold. SVT specific cams, a lighter flywheel and low-restriction exhaust complete the picture. Further improvements were made in 1999 that raised power output to 200 hp (149 kW) and 169 lb·ft (229 N·m) and were carried over in the 2000 model. The SVT engine was used in the 1998 to 2000 European Ford Mondeo and called the ST200, it also appeared in the American Ford Contour SVT.
Duratec VE
The 2.5 L, 170 hp (130 kW) V6 used in the third generation Ford Mondeo is called the Duratec VE. Displacement was decreased from 2544 to 2495 cc. They were also used in the Ford Cougar.
Mazda AJ
Mazda used the Duratec 25 block and camshaft in their 2000 MPV.[citation needed] However, they reduced the size from 2.54 L to 2.49 L to keep under a 2.5 L tax cap in Japan. This was accomplished with a reduction of the bore from 82.420 mm (3.245 in) to 81.660 mm (3.215 in). The engine produced 170 hp (127 kW) at 6250 rpm and 165 lb·ft (224 N·m) of torque. It was replaced in 2002 with the larger 3.0 L Duratec 30-based Mazda AJ.[citation needed]
Duratec 30
Ford's standard DOHC V6 is known as the Duratec 30. It was introduced in 1996 as a replacement for the 3.8 L Essex engine in the Ford Taurus and Mercury Sable. It has 3.0 L (2967 cc) of displacement and produces between 200 hp (149 kW) and 240 hp (179 kW). The same engine is used by the Jaguar S-Type, Lincoln LS, Mazda MPV, Mazda6, Mondeo ST220 and many other Ford vehicles. It is essentially a bored-out (to 88.9 mm) Duratec 25 and is built in Ford's Cleveland Engine #2 plant. A slightly modified version for the Ford Five Hundred entered production at the Cleveland Engine #1 plant in 2004.
It has an aluminum engine block and aluminum DOHC cylinder heads. The cylinders are lined with cast iron. It uses SFI fuel injection, has 4 valves per cylinder and features fracture-split forged powder metal connecting rods and an assembled cast aluminum intake manifold.
There are two key versions of the Duratec 30:
- DAMB - The Lincoln LS and Jaguar AJ30 versions have direct-acting mechanical bucket (DAMB) tappets. Output is 232 hp (173 kW) at 6750 rpm with 220 lb·ft (300 N·m) of torque at 4500 rpm.
- RFF - The Taurus/Sable/Escape version used roller finger followers (RFF) instead and produced 201 hp (150 kW) at 5900 rpm with 207 lb·ft (281 N·m) of torque at 4400 rpm.

- 2001-2005 Ford Escape/Mercury Mariner/Mazda Tribute
- 2005-2006 Ford Five Hundred, Mercury Montego and Ford Freestyle
DAMB
- 232 hp (173 kW) DAMB
- 2000-2005 Lincoln LS

VVT
The 2006 Ford Fusion, Mercury Milan, and Lincoln Zephyr feature a version of the Duratec 30 utilizing variable valve timing. The VVT is a RFF engine derived from the Mazda MZI and does not have the mechanical buckets as on the Lincoln LS version.[citation needed]
The engine has an output of 221 bhp (165 kW; 224 PS) at 6250 rpm, and 205 lbft of torque at 4800 rpm.
In second generation of the engine, it is updated to run on E85. Engine has an output of 240 bhp (179 kW; 243 PS) at 6550 rpm and 223 lb·ft (302 N·m) at 4300 rpm. Engine now includes Cam Torque Actuated Variable Cam Timing developed with Borg-Warner. Fuel saving features include adaptive knock control and aggressive deceleration fuel cutoff.[1]

Mazda MZI
Mazda's MZI version adds variable valve timing, as does Jaguar's AJ30. It displaces 2967 cc with an 89 mm (3.5 in) bore and 79.5 mm (3.1 in) stroke. Output (on the MPV) is 200 hp (150 kW) at 6200 rpm with 200 lb·ft (270 N·m) of torque at 3000 rpm. Note that the MZI name is also used in Europe on Mazda's version of the Ford Sigma I4.

The 3.0 L, 226 hp (169 kW) V6 used in the Mondeo ST220 is called the Duratec ST.
Duratec SE
The 3.0 L, 204 hp (152 kW) V6 in the Mondeo Titanium is called the Duratec SE.
