Cars : 2013 Lexus LFA
The Lexus LFA features an all-new 4.8-liter V10 developed exclusively for use in the high-dollar supercar. Power is rated at 552 horsepower and 354 lb-ft of torque. Although maximum twist doesn't come on until the needle sweeps past the 6,800rpm mark, Toyota says that 90 percent of the LFA's torque is available between 3,700rpm and the screaming 9,000rpm redline.
Because it is still a Lexus, the LFA is relatively tame-sounding at lower speeds thanks to a multi-stage exhaust system that keeps an exhaust valve closed under 3,000 rpms for reduced drone. The system opens up above 3,000 rpms to let loose a unique roar that Lexus says is akin to F1 race cars.
Power is sent to the LFA's rear wheels via a paddle-shifted six-speed Automated Sequential Gearbox. Set low and back in the LFA's chassis, the unit contributes to the car's nearly ideal 48:52 front-to-rear weight distribution. It isn't quite as quick or refined as the gearboxes of some competitors due to its somewhat antiquated single-clutch design, however.
In order to keep the LFA light on its feet, Toyota relied heavily on lightweight materials for nearly every aspect of the supercar. Aluminum was originally planned for the LFA's construction, but engineers ultimately decided to use Carbon Fiber Reinforced Plastic for the car's chassis and body as it offered even greater weight savings than did aluminum.
Designed in-house after years of painstaking research and development, CFRP is four times stronger than aluminum yet netted a 100kg weight savings according to Toyota. (Read More)
