But back to that statement about the new Buick LaCrosse sedan matching the Lexus ES 330. Regardless of whether the company has hit the mark or not, Buick is serious about bringing its cars up a notch or two. The two-step process involves giving the cars and trucks higher-quality interiors and incorporating a "Quiet Tuning" package that essentially makes the cars smoother and quieter ? you know, like a Lexus.
In Buick's eyes, the road to Lexus-like vehicles is paved with Quiet Tuning technology and in many ways it works. There are many aspects to Quiet Tuning, but the biggest gains are the result of adding laminate to the windshield and side windows, adding a noise-suppressing engine cover, recalibrating various belt-driven pulleys, revising the power steering lines and installing extra sound-deadening material throughout the cabin. A special exhaust system is also part of the package. Unique resonators and mufflers are also employed to reduce exhaust noise.
So has Buick built a real Lexus fighter in the new LaCrosse? Yes and no. If the only goal is to build a car that has a firm but supple ride combined with an ultraquiet interior, then yes, it has done just that: The LaCrosse at least equals the ES 330 in these areas. However, there is more to a great car than just a quiet interior. Some of the essential elements of a premium sedan are simply missing. Although there are plans to add one later, there is currently no navigation system offered on the LaCrosse. Also, the lack of a power-adjustable seat back is a glaring omission. The seat bottoms and lumbar adjustments are power and the seats overall are quite comfortable, but you'll have to adjust the rake of the seat back manually no matter which trim level you choose. That is decidedly un-Lexus-like.
