Prototypes for Lexus’ upcoming LF-A supercar have been spotted testing at the Nurburgring for the good part of a year but firm details about the car are still hard to come by. Most reports claim the LF-A will be powered by an F1-derived, high-revving V10 engine displacing 5.0L and developing in excess of 500hp. There are also rumors a hybrid version could be offered but how much power it will have or what affect the batteries and electric motor will have on handling and weight is still unclear. One thing we can be certain of is that the powerplant of the new LF-A will be one of hottest sound engines around, as testified by the high-speed drive-bys in this latest spy video.

Competing against such cars as the Audi R8 and BMW M6 and even Nissan’s GT-R, the LF-A will have a price tag significantly higher than any of its current offerings including the current LS600h flagship. The car’s front mid-engine placement, along with a rear-mounted transaxle and rear-mounted radiators, should allow for excellent weight distribution. The V10 is mounted in front of the passenger compartment but behind the front-axle centerline. It’s connected via a torque tube and propeller shaft to a transaxle that is controlled by paddle shifters. The torque tube is a structural member that adds rigidity to the drivetrain and chassis while also reducing vibration.

Zero to 60mph acceleration times for the LF-A should fall below the four-second mark and top speed will almost certainly exceed 200mph.

Following the launch of the coupe early next year, Lexus will add a roadster model based on January’s Detroit Auto Show concept car. However, the car will make its first public debut – albeit in full race mode - at this month’s Nurburgring 24 hour endurance challenge where it will compete alongside Porsches, Aston Martins and Corvettes. The racing version is distinguished from regular production test-mules by its chunky GT wing, bigger wheels and brakes, custom bodykit with oversized intakes and front-mount canards.
