CXL AWD – includes similar equipment to the CXL FWD, but comes standard with the 3.6L V-6.Electronic limited-slip differential splits torque across the axle to whichever wheel has more grip to enhance control in icy or wet conditions. An advanced all-wheel-drive system with electronic limited-slip differential (eLSD) is available. CXL FWD – it comes standard with the Ecotec 2.4L and offers a 3.6L direct injected V-6 it also adds leather-appointed heated seats, dual-zone automatic climate control, fog lamps, outside rearview mirror with LED turn indicators and puddle lamps, and 18-inch alloy wheels.CX – the Ecotec 2.4L engine and six-speed automatic transmission are standard, along with cloth seats, a rear spoiler, XM Satellite Radio and more.The 2011 LaCrosse is offered in three models – CX, CXL and CXS: AWD is available on 3.6L-equipped models. The Ecotec 2.4L diversifies the LaCrosse’s powertrain lineup, which also includes a 3.6L V-6 with variable valve timing and direct injection it is rated at 280 horsepower (209 kW) and 259 lb.-ft. Engineers tuned the engine to deliver greater torque at lower rpm and build it smoothly toward its peak at 4,900 rpm, giving the LaCrosse excellent performance in all driving conditions. In fact, cold-start emissions are reduced by up to 25 percent with direct injection. That means more power is made with less fuel and lower emissions. The injection of fuel directly into the combustion chamber enables a higher compression ratio to increase efficiency and horsepower. Buick expects about 25 percent of LaCrosse customers will opt for the engine.ĭirect injection technology helps the Ecotec 2.4L deliver 182 horsepower (136 kW) and 172 lb-ft.
A fuel-efficient, direct injected Ecotec 2.4L four-cylinder engine is the standard engine in CX and CXL FWD models (it was added to the lineup in mid-2010 on CX).īacked by a fuel-saving six-speed automatic transmission, the Ecotec 2.4L powertrain delivers an EPA-rated 30 mpg on the highway and 19 mpg in the city – making LaCrosse one of the most fuel-efficient cars in its segment. The LaCrosse offers a great design, all-wheel drive, a suite of advanced personal technologies and safety features, and a choice of two fuel-saving powertrains. In a still-recovering market, LaCrosse sales are up more than 200 percent when compared to the model it replaced. Redesigned from the ground up last year, the Buick LaCrosse luxury sedan rolls into 2011 building on the attributes that have made it an unqualified success.
