Chevrolet has announced that next Impala will share a rwd platform with the upcoming Chevrolet Camaro, which will be built late in 2008. Impala production will start several months later, a GM source said.

Different from the 2007 model will also be its long wheelbase and short front and rear overhangs. The car will be similar in length and width to the front-drive 2007 Impala. The passenger compartment will be larger than that of the 2007 Impala, the source said.

Also, at the Detroit Auto Show in January will debut a new re-engineered 2008 Chevrolet Malibu. The car will be similar to the Saturn Aura in shape and size. The 2008 model will be larger than the current Malibu and will have a more luxurious interior.
