lexus lfa

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. Three concept versions have been shown, each debuting at the North American International Auto Show with the LF-A designation as part of the LF Series concept line. The first LF-A concept premiered in 2005, followed in 2007 by a second LF-A with a more completely furnished interior and exterior. The third version of the LF-A, a roadster model, premiered in 2008. The production model, trademarked LFA, was shown at the Tokyo Motor Show in October 2009.

The production Lexus LFA features a new 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 of US$375,000. A circuit-tuned variant is scheduled for 2012.
In February 2000 the LF-A began development as a supercar project codenamed P280, which was intended to showcase the performance capabilities of Toyota Motor Corporation and its Lexus marque. The first prototype was completed during June 2003. Prototypes of the LF-A were spotted regularly undergoing testing at Nürburgring, the famous motorsport race track in Nürburg, Germany, since October 2004. Numerous test vehicles had been equipped with automatic retractable rear wings, and carbon ceramic brake discs.

In January 2005, the first LF-A concept premiered at the North American International Auto Show in Detroit, Michigan as a design study with no plans for production. The first LF-A concept had an overall length of 173.2 inches (4,400 mm), five inches shorter than the Porsche 911 Turbo (996) while its wheelbase measured 2,580 millimetres (101.6 in), or about nine inches longer. The concept was nearly 1,200 millimetres (48 in) in height about equal to the Ferrari F430 with a width of 73.2 in (1,859 mm). The concept name referred to Lexus Future-Advance. The first LF-A concept featured a glass roof and side cameras mounted in the side mirrors. Twin rear radiators were installed behind the rear wheels, and visible behind large screens. The rear bumper featured a triple exhaust placed in an inverted triangle formation. The wheels were shaped like turbines, and air-scoops were placed on the C-pilllars. Following enthusiastic public reaction for the LF-A concept on the autoshow circuit, development continued with a greater emphasis on a possible production model. Concurrently, Lexus was preparing for the launch of its long-rumored F marque series of performance vehicles, with a production LF-A being a possible future member of this lineup. Reports in 2006 suggested that the LF-A concept car had received the green-light for production, however these reports were not officially confirmed.
Following the original LF-A concept, development time was lengthened by the switch from an aluminum frame to a carbon fibre tub, the result of engineering efforts aimed at improving the LF-A's power-to-weight ratio. The LF-A was reported to draw engineering resources from Toyota's Formula One team. In January 2007, a restyled LF-A concept car premiered alongside the first production F marque vehicle, the IS F sports sedan. The second LF-A concept featured a more aerodynamic exterior, a near-production interior, and F marque emblems. Later that year, Lexus GB director Steve Settle indicated plans for a V10 and hybrid version of the LF-A. The hybrid version, combining a petrol engine with electric motors, would likely feature a V8 powertrain similar to that designed for the Lexus LS 600h L. LF-A test mules continued to be spotted at the Nürburgring, including early models with a large, fixed rear wing. In December 2007, Auto Express reported that the LF-A had set an unofficial 7:24 lap record at the Nürburgring.
