General Motors has announced that its new 2010 Buick LaCrosse will be available with its fuel-sipping 2.4-liter Ecotec four-cylinder. Equipped with the direct injected engine and paired with the sedan's standard six-speed automatic, GM says the combination should deliver 30 mpg on the highway and 20 mpg in town.
It will be interesting to see if the 182 horsepower, 172 pound-foot of torque inline-four will be able to effectively motivate a car of the LaCrosse's size, but either way, plugging the capable engine in the Buick ought to give GM a unique selling point against V6-only competitors like the Lincoln MKZ.
Buick says it expects about 25% of LaCrosse buyers will check the four-cylinder box at purchase time. Check out the official press verbiage after the jump.

Buick To Add Fuel Efficient Ecotec 2.4L Four-Cylinder Engine To All-New 2010 Lacrosse
New Engine Joins Two V-6s for an All-Direct Injection Lineup
DETROIT – A fuel-efficient, direct injected Ecotec 2.4L four-cylinder engine will be the third engine offered in the 2010 Buick LaCrosse luxury sedan. Backed by a fuel-saving six-speed automatic transmission, the new powertrain combination is expected to deliver fuel economy of 30 mpg highway and 20 mpg city*– making LaCrosse one of the most fuel-efficient cars in its segment.
"Buick LaCrosse customers will have the fuel-efficient option of the Ecotec 2.4L direct injection engine, a four-cylinder that is not available by key competitors, such as the Lincoln MKZ and Acura TL," said Susan Docherty, Buick-Pontiac-GMC vice president. "Features such as a rear-seat entertainment system and remote starting are other technologies that are segment exclusives, contributing to LaCrosse's balanced package of design, performance and intelligent technology."
The Ecotec 2.4L four-cylinder joins the lineup later this year as the standard engine in the LaCrosse CX. Direct injection technology helps it deliver 182 horsepower (136 kW) and 172 lb-ft. of torque (233 Nm). Buick expects about 25 percent of customers will opt for 2.4L-equipped models.
The 2.4L's 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 Ecotec 2.4L engine to deliver greater torque at lower rpm and build it smoothly toward its peak at 4,900 rpm, giving the Buick LaCrosse excellent performance in all driving conditions.
"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."
Every engine in the LaCrosse lineup is direct injected and matched with a fuel-saving six speed automatic transmission. Along with the Ecotec 2.4L, a new, direct injected 3.0L V-6 is offered and a larger-displacement, more powerful 3.6L V-6 is standard on the LaCrosse CXS model.
Quiet, low-maintenance performance
As with the 3.0L and 3.6L V-6 engines, 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.
LaCrosse and Buick's renaissance
The 2010 Buick LaCrosse luxury sedan is the newest example of the globally influenced product renaissance at Buick. It offers all-wheel drive, a suite of advanced intelligent personal technologies and safety features, and great styling that blends heritage cues with modern design.
"The new LaCrosse builds on the success of Enclave as the next step in Buick's renaissance," said Docherty. "It will attract a whole new type of buyer to our dealerships, as Buick strengthens its position as one of GM's core brands."
