2012 Chevrolet Corvette upgrades focus on track performance

To keep up on the track with the Vipers and Super Snakes of the world, Chevrolet has upgraded the Corvette for 2012.

Only offered on the Z06 and ZR1 models, the package includes the tires, 285/30-19 in front and 335/25-20 rear, and lightweight aluminum Cup-style wheels in satin black or machined finishes.

Chrysler is set to invest $500 million in Toledo Jeep assembly plant

Chrysler Group plans to invest $500 million in its Toledo North Assembly Plant and hire a second shift of workers over the next year to build a new Fiat-based SUV for Jeep, as well as other vehicles. "This plant has been chosen to build the future Jeep SUV to replace the current Jeep Liberty that will be exported to markets all over the world," CEO Sergio Marchionne said at the plant Wednesday. "Jeep is at the heart of our plans to internationalize Chrysler, a process which is being accelerated by Chrysler's access to Fiat's distribution capabilities in Europe and Latin America." Toledo North is Chrysler's only assembly plant with only one shift of workers.

Some hybrids are not a green as they seem, interest group says

Car buyers who think they are helping the planet by choosing a hybrid vehicle to aid in cutting emissions don't always get the biggest bang for their buck, according to an environmental interest group. A report from the Union of Concerned Scientists shows that some hybrids come at a much higher price tag than their similarly equipped, conventional-powertrain counterparts, yet offer little in the way of environmental gain. These not-so-green hybrids compromise their value or eco-friendliness in a variety of ways.
