Nashville, Tennessee The outgoing Impala was a surprise success for Chevrolet. In 2004, it finished as the third-best-selling car in America, behind the Honda Accord and the Toyota Camry-though that honor was achieved with substantial fleet sales and rebates. Furthermore, in 2005, the Impala finished ahead of both of those competitors in J. D. Power's Initial Quality Survey. But the Impala sold well because it's a big car for small money, not because of stellar interior design or compelling chassis dynamics. For 2006, the Impala has three new engines-including a V-8 in the SS-and new styling inside and out. The two V-6s (211 hp and 242 hp) both use variable valve timing-a first in an overhead-valve engine-and the SS's 303-hp, small-block V-8 features displacement on demand. The pick of the litter, though, is the 3.9-liter V-6. Even though it lacks the high-rpm refinement of a Japanese multivalve V-6 and, like all Impalas, must make due with only a four-speed automatic, it offers a wide torque band and good fuel economy.
The surprise disappointment in the Impala lineup is the SS, a car seemingly geared toward the NASCAR-watching family man who needs some space and craves the sound of a traditional V-8 but demands little ride or handling refinement. The V-8 is too powerful for the chassis-spirited stabs of the throttle yank at the steering wheel even at highway speeds-and the heavy engine hanging out ahead of the front axle wreaks havoc on the handling dynamics when you attempt to drive the SS quickly. All of this is further exacerbated by the steering's lack of on-center feel, a problem that plagues all Impala models.... Read full article
