Driving Impressions

Though it's heavy, the Aurora/Riviera chassis the Park Avenue uses is one of the stiffest in the entire GM warehouse, which is a plus. A stiff chassis helps the suspension engineers create ride and handling traits appropriate to a particular car's target market. It also makes it easier to keep noise out of the car, and pays long-term durability benefits.

Given this trait, it was interesting to see the handling distinctions between the basic Park Avenue and the flagship Ultra. The ride and handling traits of the standard Park Avenue are all but indistinguishable from its predecessors, traits that have earned big Buick sedans a stodgy image over the years--floaty ride quality, pronounced body roll, and vague power steering.

Thanks to its optional Gran Touring suspension, the responses of our Park Avenue Ultra tester felt much more closely related to the Riviera. The steering system, which is different from the basic Park Avenue, varies the amount of power assist as vehicle speed and/or steering wheel angle increases, providing a significantly better sense of where the front wheels are pointed.

More important, the stiffer suspension package--which also reduces ride height slightly--yielded much sharper responses in quick maneuvers. It's not quite as firm as the Riviera, but it's far from flabby and the tradeoff in ride quality is minuscule.

All in all, the Ultra's enhanced control and firmer ride lends a contemporary feel that's a pleasant step forward for Buick.

Quiet operation has always been a top priority for Buick sedans, and here too the Park Avenues represent a step forward. Wind noise has been reduced to a mere whisper, and the new unitbody does a superior job of keeping road noise out of the cabin. The supercharged engine is audible at full throttle, but we think it's worth a little extra noise to have its superior thrust.

Add roomy seats with real move-around comfort, and the going becomes positively serene, particularly in freeway cruising. The Park Avenue isn't quite as quiet as the Lexus LS 400, but the distinctions are academic in most operating situations--unlike the distinction in price.
