The sales professionals at Briggs Auto Group have a special place in their heart for the LaCrosse. Consumers who are interested in buying a 2011 Buick LaCrosse in Kansas should stop in and see them. They can answer any questions about the power boost as well as schedule a test drive of any of the great Buick models available.

The 3.6L V-6 with variable valve timing delivers a SAE-certified 303 horsepower on the front-wheel-drive LaCrosse and 264 lb.-ft. of torque with no loss in fuel efficiency. The EPA rating is still 17 mpg city and 27 highway. An all-wheel-drive version will also be available later this year.

“The changes we’ve made to the 3.6L V-6 represent greater refinements to an already well-balanced package,” said Tom Sutter, global V-6 chief engineer. “We are using the latest designs, lighter-weight components and enhancements to improve the engine’s performance, efficiency and durability.”

By using larger valves and holding them open longer, more air is pulled into the combustion chamber, for more powerful combustion. Often, the tradeoff for greater power is greater fuel consumption, but engineers optimized the fuel system for the engine’s performance parameters.

“As a result, there is more power without sacrificing fuel economy,” Sutter said. “The more-efficient combustion also means reduced emissions.”

The new V-6 uses several lighter-weight components that help maintain LaCrosse’s fuel efficiency while boosting its horsepower. The new integrated cylinder head/exhaust manifold design saves about 13 pounds compared to the cylinder heads and manifolds of the previous engine, while the new composite intake manifold saves about 5.5 pounds.

“Thanks to increased use of lightweight components and other enhancements, the new 3.6L V-6 offers 2012 LaCrosse buyers improved acceleration with no hit to fuel efficiency,” said Doug Osterhoff, LaCrosse product marketing manager. “This new engine is an attractive option on the car that’s been widely hailed as one of the most attractive luxury sedans on the road today.”

Local residents who are interested in the new lineup from Buick are urged to stop in at Briggs Auto Group - the leading Buick dealer in Kansas. Their sales team is professional, friendly, and happy to help answer any questions about the new 2012 Buick LaCrosse or any of the other great new models from Buick.
