These photos, taken just recently at Germany's famous Nürburgring racetrack, have caught a prototype Lexus LS sedan as it undergoes high-speed testing. At first glance the car appears to be a current production model, but looking closer one can note a modification to the hood on either side of the grille. Also note the large wheels, low-profile tires, and fender bulges front and rear to cover the extra-large tires.

All this indicates a future LS sedan with more performance than the current model. A look at the rear, however, shows rather small dual exhaust pipes and not two or even four giant pipes as would be likely in a turbo model or a real high-performance car. So what is this prototype? An educated guess would be a hybrid powerplant coupling a standard-size LS V-8 engine with Toyota's Hybrid Synergy Drive electric motors to give the LS improved performance while also improving fuel economy.
