I saw a ZR1 in person a few weeks ago at a private car collection in Cypress, CA. Sounded nice, interior still sucks though.
I took a bunch of pictures of it.

The ZR-1 is a truly amazing car.
The problem is that GM does not need a top-notch sports car right now. They need a top-notch econobox or minivan or midsize sedan.
It's sort of like AMD spending billions of dollars on vacuum tube research - they don't need triodes, they need a competitive budget CPU.

the only mention of jay leno by top gear is about how he and carol shelby were on the board of some auto enviro/traffic/something organization. i agree, he'd be a great guest on the show.

Jay had a thing about why he wasn't going to be on the US Top Gear, which will be an NBC show I believe. They called him and asked him if he wanted to be on that car show or something silly, so he refused.

They already paid for the development. If it turns a profit they should sell it. As long as the cash flow is positive its great for Chevy, if one of those is in the show room people will come in to check it out. More foot traffic in the showroom = more sales.

The thing with "Halo Cars" is that they are not meant to turn a profit for MOST companies. They are meant to get people into the showrooms so they buy the cars that they do turn a profit on.

They may not pay back the development but I'm sure they can recoup the production costs. As long as it costs less to produce than they are selling it for I think they should keep on selling it.

The CTS-V uses a version of that motor - slightly smaller supercharger and lower compression ratio, 550hp.

CTS-V.
LS9 is basically modified LS3 with the new Eaton TVS 4-lobe supercharger. LS3 is used in base Corvettes, G8 GXP, new Camaro, and Holden vehicles. Base Corvettes subsidizes the cost of Z06 and ZR1. If you notice, all three models look similar and all three share pretty much the same interior even down to the Chevy Cobalt steering wheel. Corvettes are one of the highest profit margin cars for GM. ZR1 as a halo car pays for itself in brand awareness and marketing.
Eaton TVS supercharger should be available in kit forms for all C6 cars by next month or so. Given Eaton is mass producing these TVS units, prices should be fairly cheap.

The LS series V8 (which is actually only 6.2 liters - the 7 liter version is only found in the Z06) is not a very modern engine design - 2 valves per cylinder, cam-in-block, pushrods, et cetera. It's just a refinement of the old-school muscle car engines of old using stronger and lighter alloys, a smaller engine block, and fuel injection. While this works very well for a $20,000 supercar engine, it's not quite so practical for a $2,000 econobox powerplant. (It's also worth noting that superchargers kill fuel economy even more than turbochargers).
The original ZR-1, weirdly, was quite different. To produce the 375hp LT5 engine under its hood, Lotus took the old-fashioned LT1 V8 and switched the 16-valve pushrod system to a 32-valve setup with four overhead cams. A version of this engine with a smaller displacement for general purpose use was dubbed the Northstar, and is used both in normally aspirated and supercharged form in various GM vehicles to this day.
American Speed is working on a supercharged LS7 (427 cu. in.) for the Ultima GTR. 800 horsepower and well over 600 pound-feet of torque.
All for just $38,000.

you sir, have just lost whatever bits of credibility you once had.
the LS series V8's are some of the smallest, lightest, most efficiently designed V8 engines ever built.
The LS7 is something like 100 pounds lighter than the V10 in the BMW M5, while producing equal horsepower and almost 100 ft-lb MORE torque.
OHC is great for revs, but GM continually shows that OHV is far from an "antiquated" and "inefficient" technology.
