The Williams FW30 is a Formula One racing car, designed by WilliamsF1 and introduced at the start of the 2008 Formula One season. The car is largely an evolution of the previous, F1|2007-season, Williams model: the FW29.cite news|title= Williams: new car a good step forward |last= Noble |first= J |authorlink= Jonathan Noble |url= http://www.autosport.com/news/report.php/id/64777 |publisher= "Autosport" |date= 2008-01-21 |accessdate= 2008-04-05 ] As with its predecessor, the FW30 is powered by engines manufactured by Toyota. The FW30 was unveiled to the public on 21 January 2008 at the Circuit de Valencia, Spain, and made its race debut at the 2008 Australian Grand Prix in the hands of 2008 Williams drivers Nico Rosberg and Kazuki Nakajima.

Design

In comparison to the preceding Williams FW29 car, Williams Technical Director Sam Michael described the aim of the FW30's construction as being "refining our package and weight distribution" rather than being a radical redesign.cite news|title= Technical analysis of the Williams FW30 |last= Scarborough |first= C |authorlink= Craig Scarborough |url= http://www.autosport.com/news/report.php/id/64781 |publisher= "Autosport" |date= 2008-01-21 |accessdate= 2008-04-05 ] Although not confirmed by Williams, weight distribution was likely moved forward somewhat, to better utilise the traction characteristics of the single-supply Bridgestone tyres.

Chassis and suspension

In common with all contemporary Formula One designs, the FW30's basic architecture is built around a carbon fibre, aramid and honeycomb composite material monocoque. The design carries over the FW29's zero keel, double wishbone suspension arrangement, along with the twin-pillar rear wing. The FW30's front wing is one area in which the design of the FW29 was not followed. In place of the older car's two-element wing a three-element design was introduced, similar to that used on the 2007 McLaren MP4-22. As with the McLaren design the Williams wing's upper element features a central section that is raised up and passes over the tip of the car's, slightly lower, nose cone. However, unlike the McLaren, the FW30's front wing is suspended from the nose cone using the forward element.

During the season various additions and modifications were made to the FW30's aerodynamic appendages. The design of the front wing bridge was tweaked slightly from the 2008 Turkish Grand Prix onward. The bridge element gained two small airflow "fences" that allowed the Williams aerodynamic team to extend the depth of the wing profile. This resulted in an increase in the aerodynamic downforce generated by the wing, without a concomitant increase in drag.

[cite web|title= Williams FW30 - enlarged brake ducts |url= http://www.formula1.com/news/technical/2008/793/546.html |work= Formula1.com |accessdate= 2008-08-11] Small sidepod winglets were significantly altered prior to the 2008 French Grand Prix, providing twin turning vanes to better control airflow over the rear of the car. [cite web|title= Williams FW30 - front sidepod winglets |url= http://www.formula1.com/news/technical/2008/794/552.html |work= Formula1.com |accessdate= 2008-08-11 ] Later in the season, prior to the 2008 German Grand Prix, Williams also altered the lower front wing elements, offering their drivers a choice of drag-reducing flap tweaks to the rearmost element. [cite web|title= Williams FW30 - front-wing development |url= http://www.formula1.com/news/technical/2008/796/564.html |work= Formula1.com |accessdate= 2008-08-11 ] At the same race tweaks were also made to the flip-up flaps in front of the rear wheels, again to reduce drag. [cite web|title= Williams FW30 - additional rear flip-ups |url= http://www.formula1.com/news/technical/2008/796/561.html |work= Formula1.com |accessdate= 2008-08-11] For the Italian Grand Prix, at the low-downforce Monza circuit, Williams tweaked the design of the FW30's bodywork, and front and rear wings. [cite web|title= Italy preview quotes: Williams |url= http://www.autosport.com/news/report.php/id/70460 |work= Autosport.com |accessdate= 2008-09-17] Sporting only a single element, with its outer edges turned upward, the rear wing was designed to reduce drag on Monza's long, fast straights, while still providing sufficient downforce during cornering. [cite web|title= Williams FW30 - Monza-specific rear wing |url= http://www.formula1.com/news/technical/2008/800/589.html |work= Formula1.com |accessdate= 2008-09-17 ] The bumps expected at the new Marina Bay Street Circuit, used for the 2008 Singapore Grand Prix, prompted Williams to tweak the design of the front wing yet again. On this occasion the central "spoon profile" was given a more rounded aspect, in place of the rather more squared-off design used to this point. The change in profile reduced downforce slightly, but resulted in the FW30 being significantly less sensitive to the changes in ride height expected as the cars negotiated the bumpy surface.

Around the drivers, in accordance with new FIA regulations,cite web|title= 2008 season changes |url= http://www.formula1.com/inside_f1/rules_and_regulations/sporting_regulations/6844/ |work= Formula1.com |accessdate= 2008-04-05] the cockpit sides are significantly raised in comparison to previous years. The exhaust chimneys were altered from the FW29's side-exit design, to a slimmer, vertical-exit one. Other, less obvious, chassis alterations include an increase in the number of cooling louvres in the upper surfaces of the side pods, made in response to a change in the orientation of the main radiators within the pods, and an increase in the backward sweep of the roll bar-mounted mid wing.

Engine and transmission

For the first time since the 2005 Formula One season Williams maintained continuity with their engine supplier. The FW30 is powered by Toyota's "RVX-08" engine, which conforms to FIA Auto cc-cu in|2400|1 V8 regulations. One major change within the engine package is due to the enforcement of a standardised, FIA-approved ECU, manufactured by McLaren Electronic Systems and distributed under the Microsoft brand. This was introduced to eliminate traction control and engine-assisted braking. Drive is via Williams' own seven-speed, semi-automatic transmission, with an electro-hydraulically activated, seamless shift mechanism.

Competition history

Launch and pre-season testing

The Williams FW30 was unveiled to the public at an FIA test session at the Circuit de Valencia, Spain, on 21 January 2008. There was no official, ceremonial launch event. In early pre-season testing the cars ran in a number of provisional liveries that marked, variously, the names of all those employed by Williams during the development of the FW30, the 85 sponsors who have supported Williams since the formation of "Williams Grand Prix Engineering" in 1978, and the team's 30th season in Formula One racing.cite news|title= More new cars in Spain |url= http://www.grandprix.com/ns/ns19995.html |publisher= "GrandPrix.com" |date= 2008-01-22 |accessdate= 2008-04-05 ]
