Corvette ZR1's LS9 inspired by BMW M V10?
It used to be that American muscle cars were competing against themselves when it came to power. But rumor has it that, in the case of the Chevrolet ZR-1, the domestic horsepower war has a new international benchmark: the BMW M-division V10.
Word is that "German competition is driving the higher horsepower and torque numbers coming to the Corvette." Chevy engineers said that the new LS9 was created to "match up favorably" with the V10 found in the M5 and M6. The supercharged 6.2-liter LS9 has 620HP and 595 lb-ft of torque, with 535 lb-ft available from 2,600 RPM and a 6,200-RPM redline. The high-revving, naturally aspirated 5.0-liter V10 has 507 HP and 385 lb-ft of torque, and goes all the way up to 8,250-RPM.
It's good to see Chevrolet taking its cues from the best, no matter whether its domestic or international. Especially when it's applied to an engine created with a different philosophy (large-displacement, low-revving grunt) to go in a car with a vastly different purpose than the M5 or M6. BMW's S85 V10 has won at least two International Engine of the Year awards for three years straight, and the LS9 still needs to prove itself. In the mean time, the far more powerful LS9 can gloat that it gets better highway gas mileage: 20 MPG versus. the V10's 17. American ingenuity, +1.

This is one swiss-cheesed blog entry. First of all, sources?

if you click the little read button, it will take you to the original post. Not such a hard thing.

"It used to be that American muscle cars were competing against themselves when it came to power."
first of all the Corvette doesn't really fall into the muscle car category - its a sports car!
Second - the Corvette was originally designed style wise and performance wise to compete with European sports cars of the 1950s like the MGs, Jaguars, Alfa Romeos. Read up on some automotive history!
If anything this is the Corvette returning to its roots as a euro fighter.

"f you click the little read button, it will take you to the original post. Not such a hard thing."
I did (as I'm sure the original poster did), and it lacks things like quotes or attributions. Basically, "TheCarConnection heard on background" that two completely different engine designs with completely different torque curves and completely different applications are somehow related by inspiration?
I think I can find a blog entry somewhere where someone asserts that the LS9 was inspired by the Miata's 2.0L I4. Doesn't make it any less ridiculous.

Interesting how in this days we have replaced the words shamelessly copy with INSPIRED.

@Carlos,
The Corvette has always been a muscle-car/sports-car hybrid.
why not the LS2LS7? 7:08PM (1/12/2008)
The Corvette started off as a 6-cylinder. At that time it had a solid rear axle. Only for a short time did it have both a V8 and a solid rear axle.
It is in no way a muscle car, it never has been.

Both LS7 and LS9 engines win against BMW's V10 hands down!
Lighter, more compact, more torque. LS7 has almost same power, while the LS9 - well, that's no contest.

I agree Alex. I'm a big bimmer fan, and have BMW factory training. I have worked with the M5's S85B50 engine. Yet Corvette's motor is the winner here in my books.

Even the LS7 is a vastly superior motor in my opinion to the M V10. Not to say the M V10 is not a fantastic motor but I think the LS7 is defiantly the superior powerplant.

Stick a large supercharger on the V10 and we may have a different story. As impressed as I am with the LS9 and its ability with the use of pushrods I still prefer the Idea of a 8500rpm V10

I agree. If you're a 'Vette fan, you probably are a torque lover, but I love me some rpms. Both motors are amazing but the BMW V10 gets my vote because of my love for high revving engines.
James 6:30PM (1/10/2008)
this story/blog is pretty irrelevant. you're comparing a v8 that revs to 6k to a v10 that revs to 8k. what's the point? you may as well compare a nissan VQ to a honda f22

wanted to add that comparing highway fuel economy in cars of different classes is not great analysis. especially when you are comparing a (relatively) light weight sports car to a midsize luxury sedan
Mobius_1 9:24PM (1/10/2008)
Exactly my thoughts, and, the LS9 has forced induction, and there is no subjective assessment of the actual engines in here (noise, smoothness, responsiveness etc)

The BMW engine has 3 oil pumps... it is much more complicated then the corvette engine.
It also has more parts = could be less reliable.

Benfolio 6:31PM (1/10/2008)
It's also German = less reliable
Andrew 9:27AM (1/11/2008)
You mean more reliable, right? I think you got confused for a second.
Scott 9:58AM (1/11/2008)
As the owner of a 3-series, I'll take a GM car over a BMW for reliability any day. However I'll take the BMW for everything else (especially resale value).
Evotec 12:28PM (1/11/2008)
@Andrew:
no im not confused,when one of the oil pumps fail does the whole sytem fail.
Three pumps means three times more possibility to fail.
