The BMEP of a 'antiquated' pushrod, single-cam, 2-valve V8 engine is surprisingly good when properly developed. Chevy has put a lot of effort into flowing those LSx heads and figuring how how to get the most out of their 1960's technology. Heck they even have VVT finally.

Key phrase.

Oh Ok thanks. So it's more like the clutch system in AMG M113 engines.

I never mentioned anything about tech involved in OHC and OHV. I think you misread. I said Eaton TVS are more advanced than old Mooneyhams.

I think he was talking about physical size. A 6.2 liter DOHC V8 will be quite a bit bigger physically than the LT1/LT4 at the same displacement.

I thought wrong then. I was thinking about displacement. I apologize MediaArtist for the misunderstanding.

I don't know how the z06 is setup. On my mustang the air simply bypassed the supercharger screws, so there was nothing to compress. The screws still spun, but without compression they spun easily.

What an awesome beast

The coolest part is that you can run this car in 4 cylinder configuration, NA V8 cylinder configuration, and Forced inducted V8 configuration. Everything on the car is track and racing inspired.

People quote the fuel efficiency of these V8s in relation to their size and whatnot, but let's use the C6, C6 Z06, and E92 M3's figures you posted. Curb weight of these respective models has a lot to do with overall efficiency; the LS3 is pushing 3,179 pounds, while the LS7 is pushing 3,132. Meanwhile, the S65 has to deal with a hair over 3,700 pounds. That's a 570 pound weight difference between the two. That will severely impact fuel economy figures no matter how the engine is made.

Just food for thought.

No problem, I don't mind discussion. MPG only decreases to 24 mpg on the highway for a 2010 camaro (ls3) which comes in at over 3800 lbs. Still doing much better than the M3.

MPG really comes down to how much torque an engine can generate while doing the least amount of work (using the least amount of energy). The S65 lacks in that department. This is simply the nature of these engines.

So even though the S65 is more "advanced" when it comes to downright performance, it lacks in all categories except for how high it can rev which to some allows it to win in the fun category.

Yeah...Definitely not happening

[MediaArtist]

That makes sense. It would be extremely expensive to create a car that is appreciably better than what GM has done with the Z06.

[CirrusSR22]

In one of those videos with the engineers/chief designers/etc they mention there's more power to get out of this engine. Seemed like a hint it'll get a power bump or special edition in the future.

Some interesting tidbits from a recent closed door session about the Z06.

Oh and I didn't say it is going to start around 120k. I said the car will cost roughly 120k. I'm referring to a car someone would actually buy, not a base model MSRP that is on the books but doesn't really exist.

IS THIS REAL LIFE

Want to get your hands on the most powerful vehicle GM has ever made? It may be time to call your bank manager, financial adviser and whoever else helps you get your monetary ducks in a row, because Chevy has now revealed pricing information for the new 2015 Corvette Z06.

Pricing starts at $78,995 for the coupe and $83,995 for the convertible. Both those figures include destination, but don't include things like tax, title, license and optional equipment. And as we revealed when the order guide surfaced, there is some enticing optional equipment on offer.

An extra $2,995 will get you the Carbon Fiber Ground Effects package with enhanced aero. $7,995 will get you the Z07 Performance Package with Brembo carbon-ceramic brakes, upgraded tires and even more aggressive aero. There are three trim levels available and a host of other packages and options you can read all about in the press release below, from the Premium Package leather trim to the Performance Data Recorder.

No matter which way you set it up, though, you're getting a 6.2-liter supercharged V8 with 650 horsepower and just as much torque. And though the price of entry may seem high, it comes down to a downright steal compared to the six figures Chevy got for the previous ZR1 (whose place the new Z06 effectively takes) and which Dodge gets for a new Viper.

[Vigilante375]

My thing with the valet mode.....is why they didn't make it so you're limited going 25 mph (maybe slower), RPMs no higher than lets say.....2k and limit the throttle to less than 50%?

Cool features but they missed one big one for a true "valet" mode.

Oh yea, under $100k fully loaded Z06! The base price is what is amazing. I cant wait to see this car tear it up on the road courses/track.

[MisterSkiMask]

A loaded 435 vert gets you up to base Z06 price...I know, different cars but the '3 series' pricing is getting out of hand.

Considering the Hellcat and whatever Mustang ends up being on par with it, Chevy will have to release something in the 700hp range in order to compete with that market. Even if it is a tuned/lightweight version of the Z06.

I wouldn't be surprised if we see a no compromise version of the z06 similar to the z/28.

Serious weight reduction and naturally aspirated. Imagine the process that brough the ls3 to the lt1 is given to the ls7. 550-600 hp naturally aspirated with 300 lb weight reduction would be sublime.

Chevy can do something with the next gen Camaro, or whatever. The Z06 is a different animal for a different buyer. It is a complete package, not some motor bolted to a terrible chassis like the Hellcat. Don't get me wrong the Hellcat is cool, glad to see it coming out of Detroit. But the Z06 is now a track monster, on par with some of the exotics costing 2-3x the money.
