Hoping to appeal to both classic-car enthusiasts and go-fast fans, and riding on the coattails of Ford's successful retro Mustang, Chevrolet debuted a concept Camaro at the 2006 Detroit Auto Show. Trademark Camaro styling cues abound, including the long hood, short deck, and wide stance. But the Camaro concept blends these traditional cues with the contemporary lines of the Chevy Corvette and Cadillac XLR. Power is also a big part of Camaro's heritage, and this concept's got plenty of it. Underhood is Chevy's 400-horsepower small-block V8 mated to a 6-speed manual transmission. This combination, general motors claims, will average 30 mpg or better due to an Active Fuel Management displacement system. Though there are no plans for production at this point, it's only a matter of time before Chevy gets back in the muscle car game.

General Motors'  Buick division showcased a new sport-utility concept at the 2006 Detroit Auto Show. Called Enclave, it's likely to hit the road in production form in 2007 and features three rows of seats and an available V8. The interior features a blend of wood and leather to create an interior Buick calls "heritage forward." Other features include power 2nd-row seats and foldout trays and "saddle bag" pouches on the back of the front seats. Enclave will replace Buick's current midsize SUVs, Rainier and Rendezvous. Base prices are speculated to start closer to Rendezvous' current $27,000, though top-line enclaves will go for about $40,000. According to General Motors, Enclave's Lambda platform will spawn additional SUVs for the automaker's other divisions, notably the Saturn Outlook and GMC Acadia. Enclave and its Lambda cousins will be manufactured at GM's Lansing, Michigan, facility.

General Motors announced that the 2008 Chevrolet Tahoe Hybrid, previewed at the 2006 Detroit Auto Show, would be the company's first "true" hybrid vehicle--meaning that it can run on gas or electric power. Utilizing a technology jointly developed by GM, DaimlerChrysler, and BMW, the hybrid system allows the vehicle to operate on electric power, gas power, or a combination of the two. The technology was unveiled to the public at last year's Detroit Auto Show on the Graphyte concept SUV. GM wouldn't discuss powertrain details, but, the automaker claims the hybrid components will improve fuel economy by as much as 25 percent over previous nonhybrid models. Additional fuel savings comes from GM's Active Fuel Management displacement system. The Tahoe was recently redesigned for 2007. The 2008 Tahoe Hybrid will go on sale alongside a hybrid version of the GMC Yukon in late 2007.

Last year, Saturn added performance models of Vue and Ion with red line badging. At the 2006 Detroit Auto Show, the General Motors division has added another color to its lineup: green. The first green line model to hit the streets will be the Vue. Powering the Vue green line is a 2.4-liter 4-cylinder engine pared with a 4-speed automatic transmission. At stoplights, green line's engine shuts off to conserve fuel. When the driver switches from the brake pedal to the gas pedal to accelerate away, an electric motor instantly restarts the engine. In addition, the electric motor provides modest assist under acceleration and powers the accessories. Saturn claims that Vue green line will average 27 mpg in city driving and 32 mpg on the highway. This represents a savings of about 20 percent versus nonhybrid 4-cylinder models. Though Vue isn't a true hybrid in the sense that it utilizes the electric motor to power the vehicle, it does offer much of the fuel-economy improvement without much extra cost. Expect to spend around $23,000 for the green line, roughly the cost of a 2006 AWD V6-powered Vue. Green line goes on sale in mid 2006.
