The Small Company Behind the World's BEST ENGINES

"Founded by two Lotus engineers in the 50s, Corsworth started with modifying existing engines for different racing teams. These teams started winning big right away, making a name for Cosworth’s engineering capabilities. This was noticed by Ford and they commissioned Cosworth to develop two race engines from the ground up.
The first called the FVA, a 4 cylinder with twin overhead cams, 16 valves,custom cylinder heads and revved to 9000 rpm and produced 225 horsepower, this engine would go on to dominate the Formula 2 for years to come.
The second engine called the DFV was a 3 liter v8 that revved to 11 thousands rpm and made around 400 horsepower, the Ferrari engine at the time made the same power but it also had 4 more cylinders, this engine even to this day is the most successful F1 engine of all time, winning 155 races, most of any other F1 engine, even if we compare this single engine to whole teams it would still be in the 4th place for wins, which is insane to think about, this shows the engineering master minds at Cosworth.
Mercedes saw the value of Cosworth and decided to trust them with the development of their engines for DTM and rally racing, thus giving birth to one of Mercedes most legendary cars, the 190E 2.3. Cosworth had to work on an existing Mercedes engine, the M102 2 liter 4 cylinder; this engine had nothing to do with racing, as it features a single cam and 8 valves. Cosworth completely redesigned the cylinder head, giving it 16 valves, twin-cams and a more sophisticated Bosch fuel injection system, the result was a power increase from 130 to 175 horsepower for the road version. With this engine Mercedes dominated DTM for years to come, as it proved to be ultra reliable which is very important for endurance racing. Cosworth continued to improve this engine as the later versions got a bigger displacement of 2.5 liters and power went up to 235 in one of the most iconic Benzes of all time, the 190e 2.5 Evo 2.

Audi was set to replace the legendary Porsche engineered RS2, and they decided to commission Cosworth with the engine manufacturing and design.
They had to work on top of an existing engine, the 2.7 twin turbo v6 found in the s4.You would think that cosworth couldn’t do much here since this engine seems too advanced for its time, but you would be wrong.
Cosworth redesigned the cylinder head, added two new turbos, replaced the intercoolers for bigger ones, beefed up the internals, they also reworked the intake and exhaust system and completely reworked the engine management. All this work led to an output of 380 horsepower, which is 120 more than the engine it was based on.
They were entrusted by Aston Martin to design and manufacture the engine of its most important car of all time, the Valkyrie. This special car got a damn special engine, a naturally aspirated 6.5 liters v12 that revs to 11 thousands rpm and produces 1000 horsepower, making it the most powerful naturally aspirated v12 ever.

Gordon Murray, the designer of the legendary Mclaren F1 wanted to create the true successor to that car, so he commissioned Cosworth for the engine development. Murray had two simple requests, the engine had to be light with the smallest displacement possible and It had to have the quickest response time of any engine ever designed for road use.
And boy did they deliver, a 3.9 liter v12 that revved to 12 thousands rpm which made 660 horsepower and it produced its max torque of 460 at 9 thousands rpm.
Bugatti saw the insane success Cosworth had with the Valkyrie and T50 engines and chose them to design and manufacture the engine for the Chiron replacement. Bugatti wanted to keep the w16 configuration but Cosworth engineers convinced them that was not a good idea for a naturally aspirated engine and they had a better idea.
The new Bugatti Tourbillon engine will be a 8.3 liter v16 naturally aspirated engine that revs close to 10 thousands rpm and produces 1000 horsepower.A truly special engine for more reasons than one, a one of a kind production engine, and who else but Cosworth could pull this off."
