I think it looks fucking awesome. 620 hp is a nice number, although I was hoping for 650. Can't wait to see the performance numbers this bad boy puts up.

this was from a press release they issued thurs morning: Performance range More than just its tremendous peak horsepower and torque numbers, the supercharged LS9 makes big power at lower rpm and carries it in a wide arc to 6,600 rpm. GM Powertrain testing shows the engine makes approximately 300 horsepower (224 kW) at 3,000 rpm and nearly 320 lb.-ft. of torque (434 Nm) at only 1,000 rpm. Torque tops 585 lb.-ft. (793 Nm) at about the 4,000-rpm mark, while horsepower peaks at 6,500 rpm. The engine produces 90 percent of peak torque from 2,600 rpm to 6,000 rpm. Heavy-duty and lightweight reciprocating components enable the engine's confident high-rpm performance, while the large- displacement Eaton supercharger pushes enough air to help the engine maintain power through the upper levels of the rpm band. "The sixth-generation design of the supercharger expands the 'sweet zone' of the compressor's effectiveness, broadening it to help make power lower in the rpm band," said Ron Meegan, assistant chief engineer. "To put it simply, the low-end torque is amazing."

Power outputs of some comparable super cars for comparison: Mercedes Benz SLR McLaren: 617hp/575tq Curb weight: 3898lbs Mercedes Benz SLR McLaren 722 Edition: 650hp/605tq Curb weight: 3800lbs Ferrari 599: 620hp/448tq Curb weight: 3722lbs Lamborghini LP640: 631hp/487tq Curb weight: 3671lbs Corvette ZR1: 620hp+/600tq Curb weight: 3350lbs Look at the Torque numbers compared to the Ferrari and Lambo! The Zr-1 while being heavier than the Z06 is still 300 lbs lighter than the next lightest vehicle. It should also be noted that this vehicle will reach its top speed in 6th gear as opposed to 5th as previous gens of the Z06 have. That means it will pull hard through the higher gears and not fall flat as the current Z06 does around 160 mph.

i've heard stories of enthusiasts already lining up outside of the GM performance center in wixom to get a peep of the engine production going on. apparently they dont let anyone in, but they're fine with people pressing their face against the glass. lol!

" i've heard stories of enthusiasts already lining up outside of the GM performance center in wixom to get a peep of the engine production going on." That may be a little bit of exaggeration. Visitors can't get past the gate without ID and clearance. but, I am sure there are alot of GM guys that find an excuse to go to the Performance Center to follow up on some "project". wink wink... And there are no windows to really speak of. Those torque and hp curves are fucking ridiculous. Mark
