Prodrive P2 Concept Bashny.Net

Talk Prodrive - mean Subaru. British engineering firm working on sports projects for many automakers, but we know it is a program brought to the factory team Subaru's World Rally Championship.





Meanwhile, such a large company as Prodrive, there are interests and outside motorsport. "Civilian" projects firm David Richards has been since the mid-nineties. Many of them are located at the junction of motorsport and extensive use of racing experience. To demonstrate such solutions built coupe and P2.



Engineering, question - AntiLag system and an active differential. A showcase of the British decided to built a sports car units Subaru Impreza WRX STI. From the car, Prodrive engineers familiar and down, borrowed engine, transmission and all-wheel drive.
AntiLag - the invention of the race engineers to get rid of one of the major drawbacks of engines with turbocharging - turboyamy. The system works like this: after the start of the working stroke of the piston is injected into the combustion chamber, and an additional portion of fuel supplied is another spark. In the presence of air, especially fed into the exhaust manifold, the mixture burns before the turbine. This "tightens up" its rotor, causing the turbine to operate even at low speeds. But to use AntiLag is racing impossible. Firstly, the system is not designed for daily ride "in polpedali" - only at full throttle! And secondly, it is very destructive effect on the turbine itself, raising its temperature and loading blast wave.



Prodrive engineers took six months to get an acceptable job AntiLag at partial loads. Question improve resource turbine also not left out. As a result, seriously boosted two-liter engine from the Impreza, which stands on a demo car, not only develops high peak power and torque (350 hp and 575 Nm), but also demonstrates the extremely flat torque characteristics. By the way, the elasticity of the engines equipped with AntiLag WRC is that their designers have started to reduce the number of steps in the gearboxes! For mass production installed on the concept car system is not yet ready, but the Prodrive company offers its services to automakers to further its operational development.



The second concept of advertised innovation - active differential ATD. The universal electronic control mechanism is intended for use in any circuit trasmissiyah. Four-wheel drive Prodrive P2 is equipped with a rear-axle and cross-axle differentials ATD. The control system takes into consideration the steering wheel angle, angular velocity of each wheel and the moment of inertia of the vehicle about a vertical axis. As explained by specialists Prodrive, they have developed algorithms differentials can function stabilization system, while not interfering with the driving slides.



Spectacular appearance demo car developed by Prodrive commissioned Peter Stevens - designer supercar McLaren F1. The Englishman was able to create an unusual and memorable appearance at the same time a couple of strokes to hint at the exotic relatives of P2 with Subaru. The low weight of the car - only 1100 kg curb weight - achieved through the use of bearing steel body with external panels made of composite plastics.

For the mass production concept car is not suitable. That's why he and the "mule" - the whole point of its construction concluded in installed units on it. But count on the appearance AntiLag or active differential by Prodrive in the series machines some of the major manufacturers is quite possible. That's only if we know what role it played in the English company? After all, buying such decisions, and often a lot of money, car firms usually do not advertise third-party author of its new products ...
