Chevy might've pulled out of NASCAR if it weren't for new Gen 6 car

We've been on the fence with NASCAR for some time now. On one hand, it's some of the closest racing anywhere in motorsports, with actual passing and door-handle-to-door-handle action as a matter of course. But on the other, it's become template racing - a personality-driven sport more about the drivers than any sort of loyalty to a particular automaker. The Car Of Tomorrow format really rammed that message home, with a racecar's identity coming down to little more than headlamp stickers slapped on the nose. That's not necessarily a bad thing in and of itself, but we've wondered for some time what's in it for the automakers, who pay big money to stay in a series that has had little increasingly little do with street car sales, let alone innovation.
Apparently General Motors was beginning to wonder the same thing. In a new ESPN report, Rick Hendrick, team owner of Hendrick Motorsports, suggests that GM would have seriously considered leaving NASCAR if it wasn't for the move away from the COT to the new Gen 6 racer. According to Hendrick, GM North America boss Mark Reuss spearheaded the charge away from the 2007 COT and toward a racecar with clearer automaker ties - cars like the new Chevrolet SS racer shown above.

Now, if we could just get more rear-wheel drive V8 coupes into showrooms....

Camaro spy shots show subtly different grille, front fascia

It looks like there some changes in store for the Chevrolet Camaro - the only thing is that we just don't know what Chevy has up its sleeve. Looking at these spy shots, we'd initially be inclined to think that there is just a minor facelift or a new special edition, but upon closer inspection, there are a few oddities about this car that definitely have us intrigued.
The most obvious difference on this prototype is the slightly restyled front fascia with a smaller lower air inlet and the two-bar grille. Then we get to some of the car's mysterious details. For starters, this fascia has the SS vent above the grille, but it looks to be blocked off. Granted this could just be a one-off piece used for testing. What really piqued our interest was at the rear of the car where it has quad exhaust outlets that are used on the ZL1. Could this be the LS7-powered Camaro that we reported on back in December?
At this point, your guess is as good as ours as to what we're looking at here, so let us know in the comments what you think this could be.

Next Corvette ZR1 to get 700 horsepower?

Word has it General Motors may offer as much as 700 horsepower in the C7 Corvette ZR1. Motor Trend reports the next Corvette Z06 will continue to rely on its naturally aspirated 7.0-liter V8 engine for thrust, but the lump will deliver substantially more power. How much more? MT says the engine could deliver up to 600 ponies. That's a jump of 95 horsepower over the current Z06, though no figures have been finalized as of yet. Right now, GM is reportedly waiting to see what sort of grunt it can glean from the next ZR1.
The automaker has already made it clear it will resurrect the LT5 name for the new supercharged V8, and if GM is already pulling 600 from the Z06, the big dog ZR1 would theoretically offer 700 horsepower. Either way, the range-topping Corvette will be suitably insulated from its less potent siblings. Stay tuned. We aren't likely to see the Z06 for at least a year, with the ZR1 trailing along at some point there after.
