2010 Buick LaCrosse CX 2.4L

A second announcement today from GM that informs of a new engine option : a 2.4-litre Ecotec unit fitted as standard on the 2010 Buick LaCrosse CX model.

Thanks to this new direct-injected 4-cylinder Ecotec engine that is paired to a 6-speed automatic gearbox, the 2010 Buick LaCrosse CX 2.4L will be able to return an estimated 30 mpg on the highway and 19 mpg in the city.

As for performance the 2010 Buick LaCrosse CX 2.4L packs 182 HP (136 kW) and 233 Nm (172 lb-ft) of torque, which means more power with less fuel wasted.

The North American automaker also announced that for 2011 it will discontinue the 3.0L V-6, with the Ecotec 2.4L and3.6L V-6 the only engine options available.

The 2010 Buick LaCrosse CX 2.4L price is 26,995 USD.

GM press release :

DETROITA fuel-efficient, direct injected Ecotec2.4L four-cylinder engine is now the standard engine in the 2010 BuickLaCrosse CX luxury sedan. Backed by a fuel-saving six-speed automatictransmission, this powertrain combination delivers an EPA-rated 30 mpgon the highway and 19 mpg in the city – making LaCrosse one of the mostfuel-efficient cars in its segment.

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

“As Buick continues its transformation, new products like the2.4L-powered LaCrosse CX are helping us reach all-new customers,” saidCraig Bierley, Buick’s

product marketing director. “It gives them afuel-efficient option that’s simply not available with the competition.”

Direct injection technology helps the Ecotec 2.4L deliver 182horsepower (136 kW) and 172 lb-ft. of torque (233 Nm). The injection offuel directly into the combustion chamber enables a higher compressionratio to increase efficiency and horsepower. That means more power ismade with less fuel and lower emissions. In fact, cold-start emissionsare reduced by up to 25 percent with direct injection. Engineers tunedthe engine to deliver greater torque at lower rpm and build it smoothlytoward its peak at 4,900 rpm, giving the LaCrosse excellent performancein all driving conditions.

The Ecotec 2.4L diversifies the LaCrosse’s powertrain lineup. For2011, the current 3.0L V-6 will be discontinued and the Ecotec 2.4L and3.6L V-6 with variable valve timing will be the two engines offered inthe vehicle. AWD will be offered with 3.6L-equipped models starting inthe 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 useadvanced propulsion technology to help us deliver more fuel-efficientcars today and in the future,” said Tom Stephens, vice chairman, GlobalProduct Development. “GM is using multiple technology pathways toachieve increased efficiency and to diversify energy sources – andwe’re applying them where they make the most sense for customers whenit comes to efficiency, performance and cost.”

Quiet, low-maintenance performance

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