If we told you there was a variant of the iconic Nissan GT-R putting out around 600 horsepower, gobs of weight-saving technology and fuel economy that can hit 25-30 mpg on the highway would you be interested? What if we told you that the added power came via the same 160 hp electric motor that rested beneath the beautiful sheetmetal of the Infiniti Essence concept at last year's Geneva Motor Show?

The crew at Inside Line are reporting that the hybrid-powered Nissan GT-R is a real possibility for production, complete with the current model's 3.8-liter twin-turbocharged V6 and a battery pack for greenification. Weight savings is of paramount importance, and Nissan plans to throw every trick in the book at the hybrid GT-R, although we'd wager that the gas-electric variant will still weigh more than the deceptively porky model in showrooms now. Of course, Nissan wouldn't be interested in a vehicle with less performance than the current model so any hybrid-equipped GT-R would have to at least match Godzilla's numbers.

With all that power comes great fiscal responsibility, so what would a GT-R hybrid cost? IL guesses $100,000 could be the price of entry, though Nissan could be looking for a little more coin than that. After all the GT-R Spec-V was rumored to cost quite a bit more and if you add a hybrid powertrain to Spec-V weight loss techniques, we could be looking at one very expensive green machine.

Audi R8 LMS could be racing in ALMS GT Challenge class in 2011

When Audi announced its new GT3 class R8 LMS race car late last year it was expecting 2009 to be a year of learning and development. As it turned out, it was a hugely successful season, landing championships in the FIA European GT series, along with the German and Belgian national series. All told, the R8s captured 23 race victories.

In 2010 the new GT Challenge class for GT3 type cars will become a permanent fixture of the American Le Mans Series as the GT1 class is consigned to history. During the 2009 season, GT Challenge was mainly the province of Porsche 911s. However, with the R8s success in Europe this year, Audi is considering offering the car to North American customers for the 2011 season. While the car could probably be competitive in 2010, Audi wants to set up a customer support infrastructure first.

Rumormill: Mercedes-Benz CLS shooting brake in the works?

Mercedes Benz ConceptFASCINATION - click for high-res gallery

German automakers have apparently all developed kyphosis, as witnessed by the BMW 5 Series Gran Turismo, the impending Audi A7 Sportback, and the Porsche Panamera. It seems the time is right for humpty-backed automobiles from Deutschland. Mercedes used the ConceptFASCINATION to spearhead the launch of its redesigned E-Class, and while it got everyone all excited during auto show season in 2008, few thought it would amount to anything productiony. That's all changed now. Sure, there are wagons; it's hard to name a more proper Estate Car than the E-Class wagon; but that's not the brass ring everyone seems to be stretching for here.

Expected at the next Paris Motor Show CLS will debut with the expected rakish form – as well as a shooting brake version. While we're all ogling pictures of the fetching three-door concept shown above, the production version is expected to carry four doors and a liftgate. While the show vehicle is fetching with its paucity of points of entry, four doors are apparently important for interesting the Asian market. Don't think of this rumored model as a replacement for anything else utilitarian in the Mercedes lineup; the CLS Brake is unlikely to usurp the R-Class and its unsalability. Rather, it will offer another stylish option in a package that is more car than bus. The world could do with more brakes - shoot on, we say.

Lilli Bertone takes the reigns of family design house

The design arm of Bertone, which is now known as Bertone Centro Srl, is finally and completely back in family hands. Last year the entire company, its design and production divisions, went into bankruptcy. Fiat bought the production side, while control of the design side was held jointly by the court and the Bertone family. Lilli Bertone, the widow of Nuccio, the last scion to run the company, closed the deal on the remaining stake that was held by the courts.

Last year it was reported that the courts would maintain their share of control for at least three years, but it appears Lilli found a way to end that stewardship early. Bertone Centro, lately famous for the Bertone Mantide, will begin offering design and engineering contract work to the automotive and rail industries.
