Announced at its official launch, the 2010 Buick LaCrosse CX will be offered with a new Ecotec 2.4 liter engine. The LaCrosse CX equipped with the new 2.4 liter Ecotec engine is priced at $26,995.

Featuring a direct injection engine, the Ecotec engine delivers a total of 182 hp and 172 lb-ft. of torque. The engine is rated at 30 mpg on the highway and 19 mpg in the city.

For the 2011 model year, Buick will drop the 3.0L V-6 engine and will only offer the Ecotec 2.4L and 3.6L V-6 with variable valve timing. AWD will also be offered with the 3.6L-equipped models.

A fuel-efficient, direct injected Ecotec 2.4L four-cylinder engine is now the standard engine in the 2010 Buick LaCrosse CX luxury sedan. Backed by a fuel-saving six-speed automatic transmission, this powertrain combination 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 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.

Now this is what i call a car with great looks !! I wonder, the GM really has to go on bankruptcy to create some great cars (forced by the circumstances)? Usually i don’t like the american design, "bigger and bolder is better" but this car has cool lines, a great interior (powered by Insignia?) and some cool engines. I think it will be a success .. just like the Insignia will be in Europe!

Only 182 hp for such a bold and bigger lacrosse? I guess it’s not enough for it. Buik should given it 300HP above.

Good mileage for a properly equipped engine. 182 horsepower is more than enough for a car that is great for city driving cause of the mileage that it can give. One more thing that is good about it is that it is affordable.

Today, there are a number of very good machine and one of them is 2010 Buick LaCrosse. I just hope they continue their good production.
