Lexus LF

The Lexus LF line is a series of concept cars built by Lexus, the luxury vehicle division of Toyota Motor Corporation. The "LF" designation refers to Lexus Future. The LF Series vehicles features coupes/convertibles, including: the LF-A, the LF-A Roadster, LF-LC, LF-CC, and the LF-C; sedans: the LF-S, LF-Sh, and LF-Gh; crossover SUVs: the LF-X and LF-Xh; and hatchbacks: the LF-Ch. The first concept vehicle of the LF Series, the LF-X, appeared in 2003. The LF Series utilizes L-finesse, a design philosophy named for "Leading Edge" and "finesse", which debuted on the LF Series concepts and later extended to all new production Lexus vehicles. New vehicle technologies on the LF Series include advanced instrumentation, multiple driver-selected vehicle configurations, hybrid and experimental powertrains, and unconventional driver interface designs. The vehicles also feature new design cues which derive from the L-finesse design language of "Intriguing Elegance" (純), "Incisive Simplicity" (妙), and "Seamless Anticipation" (予). Several of the LF concept vehicles have appeared close to their production counterparts, while the design cues of other LF concepts appeared on more distinctly different production vehicles.

The LF-A is a 2-door exotic concept car built as a prospective halo car for the Lexus division. Three versions have been shown, the first of which debuted at the 2005 North American International Auto Show (NAIAS). The designation stands for Lexus Future-Advance. The first concept was about five inches shorter than the Porsche 911 Turbo (996) with a wheelbase about nine inches longer, and was nearly 48 inches (1,200 mm) in height about equal to the Ferrari F430 with a width of 73.2 in (1,859 mm). It was powered by a V10 engine displacing 4.8 liters, generating over 550 hp (410 kW) and had a top speed around 208 mph (335 km/h). To maintain a near ideal weight distribution a rear transaxle is used and the radiators are mounted at the rear. A second revised version with a more completely furnished interior and exterior was unveiled two years later at the 2007 NAIAS as a possible future member of the Lexus F marque performance lineup. The interior gauges revealed a 9000 RPM redline, however news reports speculated that it might not make the production version. The third version of the LF-A concept, a roadster model, premiered in 2008.
