2012 Buick LaCrosse

Buick’s latest offerings like the new LaCrosse and Regal are doing well to move the brand into a better direction, the two important sedans for the American make are still receiving a little controversy for only offering four-bangers. And Buick has decided to address this concern by introducing a new V6 for the LaCrosse.

2012 Buick LaCrosse 3.6L V-6 VVT DI (LFX)The 3.6L V6 is equipped with the usual jargon, like variable valve timing and thanks to a reworked cylinder head, larger-diameter intake valves and longer duration intake camshafts, the new V6 is rated at 303-hp for the FWD model, 23 more than the outgoing GM V6 with 264 torques. Despite the power increase, fuel economy figures remain the same as the old V6, rated at 17 mpg city and 27 highway.

“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.”

Direct injection is also part of the engines equipment to help cut hydrocarbon emissions by 25% with a new, quieter fuel pump and an isolated fuel rail. Lighter internals also help reduce weight, bringing the total diet to a loss of 20.5 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.”

And while this new V6 is destined for the new LaCrosse, let’s up that it will find its way into the new Regal as well to give us power hungry enthusiasts more to look forward to.
