lexus lf-a
The Lexus LFA is a 2-seat exotic sports coupe produced by Lexus as a concept car, "halo" vehicle, racing prototype, and production model.It is the second model in the F marque line of performance vehicles from Lexus, following the IS F. V10 engine and a carbon fiber-reinforced polymer (CFRP) body. CFRP materials account for 65 percent of the LFA's body composition by mass. The LFA went into production in late 2010, with a projected run of 500 vehicles at the base price ofUS$375,000. A circuit-tuned variant is scheduled for 2012.
During LFA production, each vehicle will receive a plaque which is individually numbered, indicating the unit's place in the production run. Each LFA V10 engine will also bear the signature of the specialist who assembled it. With 20 units produced monthly, production of the entire LFA run will last for 25 months, from December 2010 to December 2012.

_Top speed 325 km/h (202 mph)
The LFA's engineers selected a V10 engine over an equivalent displacement V8 engine for its ability to rev higher,and over a V12 for its lower reciprocating mass,allowing for more rapid engine response. Lexus claims their engine can rev from idle to its redline in 0.6 seconds and an analog tachometer needle could not accurately track the LFA's changes in engine speeds. This necessitated the use of a digital tachometer which can instantly display engine speed.The engine reportedly weighs less than the manufacturer's own 3.5-liter2GR-FE V6 engine. Engineers attempted to make the engine sound like that of a Formula One car with high revs, while at the same time maintaining reliability and vibration control. Along with other manufacturers such as Ferrari, Toyota had produced their own F1 engines and chassis designs.The exhaust note has been described by Toyota engineers as the "roar of an angel",and a US television spot later used the engine sound to shatter a champagne glass via resonance frequency.
The powerplant gives the LFA a power-to-weight ratio of 5.9 lb/hp and enables it to reach a top speed of around 325 km/h (202 mph). Like the IS F Yamaha co-developed the engine cylinder heads. The engine exceeds Euro V emissions. The engine is installed with a front mid-engine placement. According to Chief Engineer Haruhiko Tanahashi a front engine layout was selected instead of a mid engine layout as it is inherently more forgiving dynamically, affording less experienced drivers a wider safety net.
On March 15, 2010, Lexus detailed the circuit-tuned variant of the LFA, plans for which were first disclosed at the LFA official press launch the previous October.The variant is officially known as the LFA Nürburgring Package in reference to the similar setup employed on the LFA race vehicles at the 24 Hours Nürburgring.The package features an extra 7 kW (10 bhp) from its V10 engine, bringing the total to 419 kW (562 bhp). The LFA hit 292 km/h (181 mph) on the last straight uphill climb, which is one of the highest speeds achieved by a stock exotic supercar on that segment of the track. An official lap time will be attempted in the next few months. Standard OEM Bridgestone Potenza RE70 performance street tires were used. The production totals are to be included in the 500-unit total LFA planned build cycle, and will be limited to a 50-unit run.At a base price of US$445,000.
The production announcement for the LFA supercar marked the 20th anniversary of the launch of Lexus. Given the high cost of construction and limited production, analysts do not expect LFA sales to be profitable. However, the coupe is intended to serve as a testbed for new car technologies, including carbon fiber mass-production, and related performance vehicle development. At its debut, a circuit-ready model was also indicated for 2012 release.
