2005 Buick LaCrosse Preview
Despite its new name, the 2005 Buick LaCrosse is not an all-new car. Rather, it is a substantially upgraded and stiffened version of the platform that has underpinned the Century and Regal since 1997. Buick says that the LaCrosse's four-wheel-independent suspension is 80 percent retuned - including stiffer springs, thicker stabilizer bars and longer rebound damper bumpers - for improved ride and handling qualities. The rack-and-pinion steering is revised for better response and on-center feel, and the four-wheel-disc braking system is completely new. Three levels of traction control are offered, with GM's StabiliTrak stability control system available on the top trim level. The 2005 Buick LaCrosse also receives QuietTuning, the name applied to increased sound-deadening efforts designed to make all Buicks very quiet inside.
Three models will go on sale in the fall of 2004. The base CX and upscale CXL are powered by GM's tried-and-true 3.8-liter overhead-valve V6 engine, driving the front wheels through a four-speed automatic transmission. Upgrades to the powertrain include the addition of electronic throttle control and refinements expected to result in quieter operation. Futhermore, it meets super-ultra-low emissions vehicle (SULEV) standards. Making 200 horsepower, the 3.8-liter V6 is predicted to return 20 mpg in the city and 29 mpg on the highway.
Under the hood of the sporty 2005 Buick LaCrosse CXS is an aluminum DOHC 3.6-liter V6 making 240 horsepower and 230 lb.-ft. of torque, 90 percent of which peaks between a useful 1,600 and 6,000 rpm. Cribbed from the Cadillac CTS and also employed in the Buick Rendezvous Ultra, this modern 3.6-liter V6 is equipped with variable valve timing and is expected to produce 19 mpg in the city and 28 mpg on the highway. Dual exhausts provide a sportier engine note on the CXS.
