Acura NSX Concept

Acura NSX Hybrid Concept Car at Detroit Auto Show

After months (if not years) of waiting, Acura has finally unveiled their next-generation NSX Supercar. Though still a concept, the it boasts the car’s future exterior design inspiration as well as what’s under the hood. Power comes from a mid-rear V6 engine that’s made to an electric motor to form a hybrid setup. The SH-AWD setup also features a dual-clutch transmission for added performance, while the two motors can instantly send negative or positive torque to the front wheels for improved handling. No word yet on horsepower figures but expect the power-to-weight ratio to be top-notch.

Yesterday at the 2011 NAIAS Detroit Auto Show, Porsche took the covers off their latest concept car, the 918 RSR Racing Lab. It looks magnificent but it’s really what makes it move and punch it’s packing that’s got our attention. The supercar is built on a stiff carbon fiber plastic monocoque and is gets power from a direct-injected V8 that dishes out 563-hp, the same found in the RS Spyder. There are actually two electric motors on the front wheels which contribute a burst of 150 kW bringing overall output to peak drive power of 767-hp. This additional spark is generated during braking and is stored in an optimized flywheel accumulator and is available for roughly 8 seconds when the system is fully charged.

When mated to a 3-phase synchronous electric motor, the BMW ActiveHybrid 7 produces a total of 455-hp with a maximum torque of 516 lb-ft. Power is driven to the wheels via an 8-speed automatic transmission with the electric motor (powered by lithium-ion batteries) positioned between the engine and the torque converter.
