The sedan was initially slated for availability this spring, but a technical issue forced the company to return to the drawing board. The exact nature of the problem has never been publicly confirmed, though speculation naturally pointed to issues with the new ‘Super-Handling’ all-wheel-drive technology.
The Sport Hybrid pairs a 3.5-liter V6 engine with three electric motors, one at the front of the car and two for the rear wheels. The approach eliminates the drive shaft and rear differential, instead tasking electric motors with directly vectoring torque to each rear wheel.
Driven together, the gasoline engine and electric motors produce 377 horsepower and 341 lb-ft of torque, with an EPA highway rating of 32 mpg.
Acura will eventually use a similar hybrid all-wheel-drive system in its upcoming NSX sports car.
