"Chevrolet updates its largest sedan and coupe for 2006 with new engines, reworked suspensions, and revised exterior styling. Both the Impala sedan and the Monte Carlo coupe are offered in LS, LT 3.5, LT 3.9, LTZ, and sporty SS trim. LS and LT 3.5 models come with a 211-hp 3.5-liter V6, up 30 hp from 2005's base engine. LT 3.9 and LTZ models have a 242-hp 3.9-liter V6. SS models get a 303-hp V8 with GM's Active Fuel Management, which deactivates four cylinders under light throttle conditions to save fuel. All come with a 4-speed automatic transmission. SS models have sport suspension and 18-inch wheels; others get 16s or 17s, depending on model.
Available for all Impala models except SS is a front bench seat for 6-passenger seating. SS and all Monte Carlos come only with buckets. Head-protecting curtain side airbags are standard on Impala. They are not available for Monte Carlo, but front torso side airbags are optional. ABS and traction control, are available. GM's OnStar Assistance is standard. Available are a remote starter that turns the engine on via the keyfob, leather upholstery, and satellite radio. "

"Impala is getting a makeover for 2006. Sources can't say how extreme it might be, but we think it will emulate the latest Pontiac Grand Prix and Buick's new LaCrosse in giving the current model fairly extensive cosmetic and engineering changes. Monte Carlo, the Impala's coupe sister, gets a similar treatment for '06. A rumored V8 option for both models has apparently been postponed so Chevy can assess sales potential--and the effects a V8 would have on meeting corporate average fuel economy standards.
Even so, there's talk of a new full-size Chevy sedan with rear-wheel drive as well as V8 power. Sources can't say when or even if this car might appear, but it would surely be built on the new rear-drive Zeta platform being developed by GM's Australian subsidiary for new rear-drive models at other GM brands. Stay tuned."
