The LaCrosse CX with the Ecotec 2.4L has an MSRP of $26,995. Buick expects about 25 percent of LaCrosse customers will opt for it.

“As Buick continues its transformation, new products like the 2.4L-powered LaCrosse CX are helping us reach all-new customers,” said Craig Bierley, Buick’s product marketing director. “It gives them a fuel-efficient option that’s simply not available with the competition.”

Direct injection technology helps the Ecotec 2.4L deliver 182 horsepower (136 kW) and 172 lb-ft. of torque (233 Nm). The injection of fuel directly into the combustion chamber enables a higher compression ratio to increase efficiency and horsepower. That means more power is made with less fuel and lower emissions. In fact, cold-start emissions are reduced by up to 25 percent with direct injection. 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.

The Ecotec 2.4L diversifies the LaCrosse’s powertrain lineup. For 2011, the current 3.0L V-6 will be discontinued and the Ecotec 2.4L and 3.6L V-6 with variable valve timing will be the two engines offered in the vehicle. AWD will be offered with 3.6L-equipped models starting in the 2011 model year.

Like the Ecotec 2.4L, the 3.6L V-6 features direct injection.

“Direct injection is a key component of GM’s ongoing strategy to use advanced propulsion technology to help us deliver more fuel-efficient cars today and in the future,” said Tom Stephens, vice chairman, Global Product Development. “GM is using multiple technology pathways to achieve increased efficiency and to diversify energy sources – and we’re applying them where they make the most sense for customers when it comes to efficiency, performance and cost.”

Quiet, low-maintenance performance


The Ecotec 2.4L is designed to deliver exceptional quietness with low maintenance requirements and minimal environmental impact – including 100,000-mile service life ratings for the spark plugs and accessory drive belt. It is also equipped with GM’s Oil Life system, which uses a sophisticated algorithm to determine when it’s time for an oil change. The system calculates the oil life based on a variety of closely monitored variables, such as engine speed, temperature, load and others, allowing fewer oil changes over the life of the vehicle for a significantly reduced amount of used oil that must be recycled.
