GM’s new LS9 6.2-liter supercharged V8 engine has been officially certified by SAE as having a maximum power output of impressive 638 hp and peak torque of 819 Nm (604 lb-ft).
Delivering almost 103 hp per liter, the supercharged LS9 (the mill is equipped with a sixth-generation Eaton TVS R2300 roots 4-lobe supercharger with intercoolers from Behr that dramatically increases the unit’s efficiency) is the most powerful engine ever installed by GM in a production vehicle. In the 2009 Chevrolet Corvette C6 ZR1 supercar, that is.
With so much power available under the hood, the ZR1 will have a speed limit in excess of 200 mph.
According to GM, the new C6 ZR1 is equipped with a seriously upgraded 6-speed manual gearbox and features a heavy duty limited slip differential with carbon and steel plates that will help a driver to better utilize all that energy on a Nurburgring or some other demanding track.
What is even more wonderful is that the car with its aluminum body and lots of carbon fiber panels and a curb weight of just 1544 kg (slightly over 3400 lb) will be the most fuel-efficient vehicle with an over 600 hp capable engine when it comes to market in the middle of the year.
