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 is the most powerful engine ever installed by GM in a production vehicle. In the
2009 Chevrolet Corvette ZR1, that is. With so much power available under the hood, the
ZR1 will have a speed limit in access of 200 mph. What is even more wonderful is that the car 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.
