Official horsepower and torque figures prove even higher than the estimates. We bow low to GM’s powertrain gods.

As if there weren’t enough superlatives surrounding the 2009 Chevy Corvette ZR1, we learn General Motors undersold the grunt of its most expensive and most powerful production Corvette ever.

We were already enthralled as we dreamed of an estimated 620 hp at 6500 rpm and 600 lb-ft of torque at 4000 rpm from its supercharged LS9 6.2-liter V-8. Not so fast, says GM to anyone wed to those impressive figures—it’s actually more powerful!

Having completed SAE certification for the first factory-built Vette with forced induction, the true numbers are a dizzying 638 hp and 604 lb-ft of torque. Do the math and that’s nearly 103 horses per liter, or just about 1.7 hp for each of the engine’s 376 cubic inches. Well worth the expected hundred grand price tag (or about $110,000 for the loaded 4LZ trim level).

GM says it has not completed its fuel economy testing, but engineers assure us it will be “the most fuel-efficient 600-plus-horsepower car on the market.” We actually thought it was illegal to put the words ‘fuel efficient’ and ‘600 horsepower’ in the same sentence—and given that enthusiasts likely will be willing to maim one another for one of only 2000 ZR1s (all with handmade engines) to be built a year, we suggest anyone who asks about mpg be immediately disqualified from ownership.
This snorting beast goes on sale in August or September.

More than expected. I approve.

Mmyea... it's pretty powerful.. I guess..

[silverhawk]

638 HP!!!! if it can corner properly then im sold

[fisetdavid26]

I'll take an all-black one please.

They also tested it at some high-speed ring and got up to 205 mph.

here's another link too. Corvette ZR1 Certified at 638hp - GM Inside News Forum


Im sure it will be able to corner, the standard z06 corners just fine so you gotta assume the zr1 will handle good also.

im surprised about the 205. i read in road and track they got the z06 up to the high 190's (198ish) i would think that 100 extra horsepower would be good for more than a few mph but 205 is still pretty sweet and i know there's a lot more to top speed than hp.

As speed doubles, drag squares, so it takes lots of horsepower at that upper end for a small increase

Going to be interesting,

BTW .... .... another example of a US citation for hp/l
Years of devotees sayign it doesn't matter, it doesn#t matter but as soon as the 'vette can do over 100hp/l then it gets mentioned

I love the "close ratio gearbox - 65mph in first gear!"...

That's pretty much like all close-ratio gearboxes on powerful cars. Long 1st to get up to speed, then 2nd -> 6th close packed together. Though this will undoubtedly be 2nd -> 5th close, then moonshot 6th. If you don't have the long 1st with close-ratio box, you'll limit the top speed.

That is even better than a '68 Dodge Charger R/T with 426 Hemi (that did 63 mph in first gear with a 3.23 rear axle ratio and automatic trans).

Odd that, like Matra pointed out, GM again makes a big deal of pointing out the fact that this engine is just north of 100HP/L.

I thought the idea of specific output was something that didn't matter

Anyways GM should be thrilled. They raised the bar and created a new level of Halo car while still maintaining a great bang-for-buck value.

Think about it, you can get it fully kitted for an est. 110,000USD and you get 638HP for that (alittle over 172 bucks per HP) and more importantly some of the biggest most hardcore brakes.

I can finally say that I would be proud to have a ride in or drive a ZR1.


BTW: I know that technically the Z06 is even better bang-for-your-buck value but it has some other issues that I think the ZR1 handles. IMO the ZR1 is deserving of the Supercar moniker aswell as being drive-everyday friendly.
