The vette might be able to pull off something close. Maybe 3100-3500. All depends on the unsprung weight, and whatever they are using as a frame.

I don't think 2800 is a bad figure to aim for.

2 will be coming, so it will be easy to find out

one for the personal, one for the maka-da-money-back.

I'm just a conduit for this 2800 lbs. of information

We are already at 3100lb's and have been for 7 years

The C6 Z06 suffers from a huge amount of heavy glass, extra comfort crap and wider heavier wheels and brakes - and even with carbon fibre bits and an aluminium frame was only able to get back down to 3100lbs.

Race Corvettes get all their weight saving from removing a lot of weight - gutting, cutting, removing and exotifying the materials used.

Hell, even the lightest turbo or super charger setup weighs 100lbs. so youwin some and lose some.

The construciotn would have to go Saleen like to get to some crazy low weight

oof. I didn't even think about the glass. That wrap around rear window must kill it

too bad lexan isn't allowed for street use.

How you think they could save be trimming out .25 inches of upholstery? the carpet in that thing has to weigh quite a bit. Mainly from the padding i'm sure they doubled up on for sound deadening.

Have the LSx blocks gone to AluSil yet, or are they still just aluminum? might save some weight there...

If they're at 3100 now, how hard can another 300 be? :bah:

Looking forward to a confirmation of the 7.25 lap time on the CTS-V with street legal tires. If Sport Auto confirms this time on a production specimen, then GM really does know how to build a performance saloon.

Undercutting an M5 by half a minute is pretty amazing, you could enter this car on street tires and be competitive at the Nurburgring 24h. Who needs Oreca Vipers and C6Rs when you can run as fast with aircon and satnav?

you misread, CTS-V will be sub 8 minute, and Corvette SS will be near 7:25

Not quite true.. Lexan isn't allowed for windshields. All the rest of the windows can be lexan. In fact, the current base coupes removeable 'targa' is a generic version of Lexan (Lexan is just a brand name, the actual technical term is polycarbonate). My Trans Am's ttops are also Lexan if I'm not mistaken. Several of the porsches come with options for lexan hatches. Then again.. those targa tops are a $1400 option, Lexan isn't cheap.

Cadillac are making a A8 L, Merc S klass, BMW 750 iL competitor, and making a brand new V12 engine, the Engine is basically a pair of caddy v6's (DOHC) together, with a new crank (of course) and being a 600+ hp beast in top-of-the range form

More on the CTS-V from Autoblog:
The new issue of Motor Trend arrived in the mail and our eyes were instantly attracted to this story that just went live on motortrend.com. The MT crew has learned that the supercharged V8 slated for use in the next-gen Cadillac CTS-V will be none other than a "detuned" version of the 7.0L LS7 powerplant debuting in the Corvette Blue Devil, or rather, Corvette Z07. The MT editors expect the version used in the CTS-V to produce about 600 horsepower, or around 100 horses short of what the Z07 will produce.

Pick any possible competitor for the next CTS-V and it's obvious that all will come up short to Caddy's new mega muscle sedan. The BMW M3 and Audi RS4 both produce only 420 horsepower, while the horsepower happy AMG team stuffed only 503 in the Mercedes-Benz C63 AMG. Even the BMW M5, which is larger than the CTS, will come up short with an upcoming horsepower bump into the low-500 horsepower range. In short, the CTS-V will offer the same amount of horsepower as the 2008 Dodge Viper, which is pure insanity. GM's got stones, folks, and Cadillac is clearly the prime beneficiary of its newfound fortitude.

Much thanks to Motor Trend editor-in-chief Angus Mackenzie for allowing Autoblog to republish the rendering above. The July issue (you can subscribe here) is thicker than a Thesaurus and our fave in a string of recent good issues from the MT team.

Can we confirm the info above? MT does a lot of hit or miss stuff when it comes to scoops.

motor trend is wayyyyy off here

the CTS-V that will be coming out as previously mentioned is a 5 valve headpushrod V8 making roughly 510 hp... and MT's staff are kinda off thier kilter for names... maybe because they are way out on the left coast, far from the automotive circles of Detroit.

Supercharged corvette = blue devil = Corvette SS [ not Z07 as previously mentioned by MT, and I am not very sure that the LS9 in the SS is going to be "detuned" and put in the next CTS-V... i'm pretty sure it's an all new motor from Caddy.
Engine = LS9,
few details known beyond that its roughly 647 hp, 2800 lbs, wider up front/rear, carbon fibre body, wider tires front and rear, and potentially carbon brakes.

General Motors, the world’s largest automaker, has the world’s largest headache on its hands. GM announced after the bell on Tuesday that it will take a $39 billion non-cash charge in the third quarter related to establishing a valuation allowance against its deferred tax assets in the United States, Canada and Germany.

GM (nyse: GM - news - people ) shares closed up 0.4%, or 16 cents, to $36.16, but dropped 3%, or $1.06, in after-hours trading after the news of the charge broke.

GM is expected to report third-quarter results on Wednesday.

The company said that in the past it had evaluated its deferred tax assets quarterly and determined that valuation allowances were not necessary in the U.S., Canada and Germany because its three-year losses were due to one-time expenses and it still expected strong earnings at GMAC Financial Services (nyse: GJM - news - people ). But now the automaker said that accounting standards require it to establish a valuation allowance due to developments in the third quarter. One significant factor was the company’s three-year historical cumulative loss in the U.S., Canada, and Germany on an adjusted basis. Another factor was the substantial losses incurred at GMAC related to its residential capital mortgage business, of which GM owns 49%. Challenges in near-term automotive market conditions in the U.S. and Germany also played a role.

“The establishment of a valuation allowance does not have any impact on cash, nor does such an allowance preclude us from using our loss carry forwards or other deferred tax assets in the future,” said Fritz Henderson, GM’s chief financial officer.

Henderson said that the establishment of a valuation allowance “does not reflect a change in the company’s view of its long-term automotive financial outlook.” The company still believes that its new products and the new GM-United Auto Workers agreement will improve GM’s position in the U.S. and better position it to use tax benefits in the future, Henderson said.

But David Healy, a Burnham Securities analyst, said that the charge is an indication that GM’s outlook is not as strong as it was a few months ago. “It’s a deterioration in their short-term outlook,” he said.

GMAC suffered a large loss in the third quarter and the provisions GM took were not sufficient, Healy said, which may mean further write-downs are expected.

GM officially has hired retards to function as accountants....

39 Billion is nothing to blow in the wind against!

Official: Cadillac CTS-V unveiled

http://www.blogsmithmedia.com/www.au...09ca_ct002.jpg

Our friends over at Jalopnik say the CTS-V is officially fair game now, so here we go. Now that the second generation Cadillac CTS is on the streets and garnering largely positive reviews for its looks, performance and handling dynamics, the time has come to turn it up a notch. The 2008 Detroit Auto Show will bring us the second generation high-performance CTS-V model. Just as the original 2004 version used an engine derived from the top Corvette of the time, so too does the new model. The 2009 CTS-V leap-frogs its chief competitor - the BMW M5 - with GM's new LSA V8 derived from the LS9 in the Corvette ZR1.

The goal of the CTS-V development team was to create a car with the poise and sophistication of the best luxury sedans melded with the outstanding performance of a high sports car. To achieve that they installed the supercharged 6.2L V-8 with an output of 550 horsepower and 550 lb-ft of torque into a heavily upgraded chassis and then went about dressing up both the interior and exterior to match.

DETROIT, Mich. — If the Cadillac CTS Coupe concept that debuted at the 2008 Detroit Auto Show made your heart beat faster, then here's something that might make it explode. GM will put this dramatic display of its Art and Science design language into production in 18 months' time.

While Ed Welburn, GM's vice president of Global Design, told reporters at the CTS coupe's press conference "this vehicle really wasn't supposed to exist," the new luxury coupe has been part of GM's plan since at least the middle of 2006. Code-named GMX226, the 2010 Cadillac coupe will start rolling down the assembly line at the Lansing Grand River plant in early June of 2009. Annual production is expected to be in the range of 15,000 to 20,000 units.

Don't expect the production model to differ much from the concept. In back, the very short rear deck lid, angular taillights and sculpted sheet metal will appear on the real coupe. One thing the production model will have, that the concept does not, is a lip spoiler with an integrated middle brake light. The center-mounted exhaust will also be swapped out for a more conventional setup.

Good decision and a good business move in my opinion. Design is great as well!

corvettekid · 01-23-2008, 01:14 AM

i went to the detroit NAIAS yesterday and with out a doub the CTS coupe was by far the best looking car. i would take a CTS over any 3 series, c class, or a4.
