The 2007 Chevrolet Impalat LTZ Sedan includes 17-inch alloys, heated leather bucket seats, a Bose audio system and an auto-dimming rearview mirror. The LTZ is so well-equipped it has no options apart from a CD changer and a sunroof (which is optional on all trims). Available on the LT and standard on the LTZ is a 3.9-liter V6 (233 hp and 240 lb-ft), which is now fitted with Active Fuel Management technology, which deactivates half the cylinders while cruising to save fuel

Antilock brakes and traction control are standard on the LTZ, and optional on other models. Full-length side curtain airbags, OnStar and a tire-pressure monitor are standard on all Impalas, but stability control is not available. In side-impact testing, an Impala equipped with the side airbags scored five stars for front passengers and four stars for those seated in the rear.

As one of the few sedans on the market capable of seating six passengers, the Chevy Impala does have an edge on the competition when it comes to interior space. The LTZ model has metallic interior trim, while all other models feature wood-grain trim. Fit and finish is vastly improved over previous models, and the Impala offers contemporary features like available dual-zone climate control, a Bose audio system and an input jack for portable music players. Trunk capacity is a generous 18.6 cubic feet.
