The Supers are engineered for Buick by GM’s Performance Division and feature upgraded V8 engines, sport-tuned suspension systems with Magnetic Ride Control and Bilstein monotube struts, larger front and rear brake rotors, and recalibrated chassis controls, all of which help improve the dynamics of the new Super models. The LaCrosse Super introduces a V8 engine that has the fuel efficiency of a V6. It’s rated at 300hp (224kW) and 323lb-ft (438Nm) of torque and can propel the LaCrosse Super from 0-60mph in 5.7 seconds. The Lucerne makes do with a more powerful version of the 4.6L Northstar V8 engine, rated at 292hp (218 kW), which is 17hp (13 kW) more than the Lucerne CXS.
Visually, the cars are enhanced with Buick’s latest take on the classic waterfall grille and porthole design, the first time the design cue has featured on the LaCrosse model. The 2008 model will also offer four new exterior colors, including Scarlett Red, Gold Mist Metallic, Dark Mocha Metallic and Dark Slate Metallic. Owners are treated with a factory remote start feature, XM Satellite Radio, a telescoping steering wheel column, redundant steering wheel controls and dual-zone climate control as added standard equipment.
The LaCrosse line offers two other powertrains in addition to the new Super model. These include a 3.8L V6 rated at 200 horsepower (149 kW) and a less powerful 3.6L version with 240hp (179kW) on tap.
