2005 Buick LaCrosse

Lutz also challenged the chassis engineers to morph LaCrosse's dynamic character from Buick soft to Euro lithe, and they effectively did. Standard and up-level CXL models share Buick's best-ever base suspension, and the sportier CXS—with Gran Touring suspension, quicker (13:1) steering, bigger wheels and tires and GM's terrific 240-hp 3.6L DOHC 24-valve VVT V-6—can hold its own on with the planet's best premium sedans challenging two-lane roads.


"LaCrosse is very important," says Marketing Director Mark Hines. "Not only does it set the stage for renewal of our entire car line, it replaces two models that account for almost half of Buick car sales. [And it] represents four key attributes that Buick will continue to emphasize: smooth power, elegant design, expertly crafted interiors and a comfortable yet responsive ride."

A cleanly crafted, ergonomic interior makes good use of quality soft-touch materials and chrome and woodgrain accents.

It debuts in three versions: standard but well-equipped CX, "elegantly appointed" CXL and performance-oriented CXS. CX and CXL are powered by GM's 200-hp 3800 V-6, a likeable veteran in Buick's Park Avenue, LeSabre and Regal and a host of other GM cars. Among its "Series III" upgrades are structural improvements for quieter operation and electronic throttle control to improve response and efficiency while reducing complexity.


LaCrosse sits on an updated version of GM's "W" (Pontiac Grand Prix, Chevy Impala) architecture with much-improved structure and suspension. Its 4-wheel-disc brakes are larger and more durable, its (15:1) power steering re-tuned for precise response and on-center feel. Its wheels—increased to 16 inches on CX and CXL and 17 inches on CXS—wear higher performance, lower aspect ratio tires with a specially formulated tread pattern.


The standard springs are 20 percent stiffer, higher-rate stabilizers give improved roll resistances and rebound bumpers are four times longer for improved cushioning. Three available levels of traction control include GM's StabiliTrak stability enhancement system, a first for a midsize Buick. The result is a surprising balance of smoothness and agility.
