For starters, the 2007 Impala impresses with its new generation V6 engines, particularly the 3.9 liter V6 which offers improved fuel economy through GM's Active Fuel Management System in its engine.

The new models have the standard tire-pressure monitor as well as the OnStar service, which has been upgraded with a new navigation service that guides you turn by turn. If you're in a crash, Onstar will tell 911 how severe the damage is and automatically communicate your location.

As a mid-size sedan, it's a big car but the Impala is nearly a full-size too large for that class. The Imapala is big enough to allow you easy entry and exit, plus thh front and back seats are pretty spacious. The trunk is huge and you can flip and fold the back seats for even more cargo space.

On the road, the Impala cruises easily and is very stable. Handling is superb and even surprising given its size. The V6 engine, especially the larger 3.9 liter V6, provides plenty of low-end torque.

The 2007 Chevrolet Impala comes in several models, ranging from reliable family sedans to sleek performance cars. An excellent example of the model line is the mid-level Impala LT because it's strong, reliable and fuel efficient with its 3.5 liter V6 engine, which is standard for both the LT and LS. The 3.5-liter V6 has 211 horsepower and 214 pound-feet of torque.

The LT also has an option for the 3.9 liter V6 engine which generates 232 horsepower and 240 pound-feet of torque. Meanwhile, the LTZ has all that as well as leather interiors. The SS boasts of the 5.3 liter V8 engine, with 303 horsepower and 323 pound-feet torque for superb acceleration. The SS has the most power and torque among all the models in this class.

All models are equipped with the four-wheel disc brake system, which is a vast improvement over past models. It has new front brakes and stronger rear brakes as well as a brake booster.

In terms of competition, the Impala is usually ranged against the Honda Accord, Nissan Altima, Toyota Camry, Dodge Charger and Ford 500.
