The gearbox is constructed of carbon titanium, as heat dissipation is a critical issue, and is bolted onto the back of the engine. Transmission The gearbox with mounted rear suspension elements from the Lotus T127, Lotus Racing's car for the 2010 season.įormula One cars use highly automated semi-automatic sequential gearboxes with paddle-shifters, with regulations stating that 8 forward gears (increased from 7 from the 2014 season onwards) and 1 reverse gear must be used, with rear-wheel-drive. The engine produced over 865 hp 18,300 rpm, and was used in the highly-successful Ferrari F2004, in 2004. In addition, it means that the air moving through the compressor is much cooler since it is farther away from the hot turbine section. The benefit is that air is not traveling through as much pipework, in turn reducing turbo lag and increasing the efficiency of the car. One of the many reasons that Mercedes dominated the season early, was due to the placement of the turbocharger's compressor at one side of the engine, and the turbine at the other both were then linked by a shaft travelling through the vee of the engine. This change may give an improvement of up to 29% fuel efficiency. Turbochargers had previously been banned since 1989. This method of limiting engine costs also increases the importance of tactics, since the teams have to choose which races to have a new or an already-used engine.Īs of the 2014 season, all F1 cars have been equipped with turbocharged 1.6 L V6 engines. However, for the 2009 season, drivers were allowed to use a maximum of 8 engines per head over the season, meaning that a couple of engines had to last three race weekends. In the 2008 season, engines were required to last two full race weekends the same regulation as the 2006 season. In 2007, this rule was altered slightly and an engine only had to last for Saturday and Sunday running. For the 2005 championship, they were required to last two full race weekends and if a team changes an engine between the two races, they incur a penalty of 10 grid positions. In the 2004 championship, engines were required to last a full race weekend. The engines are a stressed member in most cars, meaning that the engine is part of the structural support framework, being bolted to the cockpit at the front end, and transmission and rear suspension at the back end. Īll cars have the engine located between the driver and the rear axle. In 2012, the engines consumed around 450 L (16 cu ft) of air per second (at the 2012 rev limit of 18,000 rpm) race fuel consumption rate was normally around 75 L/100 km (3.8 mpg ‑imp 3.1 mpg ‑US). The only team to take this option was the Toro Rosso team, which was reformed and regrouped Minardi. The lesser funded teams (the former Minardi team spent less than 50 million, while Ferrari spent hundreds of millions of euros a year developing their car) had the option of keeping the current V10 for another season, but with a rev limiter to keep them competitive with the most powerful V8 engines. Even with the restrictions, the V10s in the 2005 season were reputed to develop 730 kW (980 hp), power levels not seen since before the ban on turbo-charged engines in 1989. The FIA has continually enforced material and design restrictions to limit power. Teams started to use exotic alloys in the late 1990s, leading to the FIA banning the use of exotic materials in engine construction, with only aluminium, titanium and iron alloys being allowed for the pistons, cylinders, connecting rods and crankshafts. įor a decade, F1 cars had run with 3.0 L naturally aspirated engines with all teams settling on a V10 layout by the end of the period however, development had led to these engines producing between 730 and 750 kW (980 and 1,000 hp), and the cars reaching top speeds of 375 km/h (233 mph) (Jacques Villeneuve with Sauber-Ferrari) on the Monza circuit. The 2009 season limited engines to 18,000 rpm in order to improve engine reliability and cut costs. Further technical restrictions, such as a ban on variable intake trumpets, have also been introduced with the new 2.4 L V8 formula to prevent the teams from achieving higher RPM and horsepower too quickly. The 2006 Formula One season saw the Fédération Internationale de l'Automobile (FIA) introduce a then-new engine formula, which mandated cars to be powered by 2.4 L naturally aspirated engines in the V8 engine configuration, with no more than four valves per cylinder.
