While Buick, a division of General Motors company (NYSE: GM) is more often known as a modern luxury brand, offering vehicles with sculpted designs, luxurious interiors with thoughtful personal technologies, along with responsive-yet-efficient performance, the engine award from WardsAuto World returns Buick to the world of engine power performance, albeit in a smaller displacement than in the past.
Just look at the power-to-displacement ratio. According to the GM news release, the Ecotec 2.0L turbo’s 270 horsepower is the highest specific output of any GM production engine, and at 135 hp per liter, is the most power-dense engine certified by the Society of Automotive Engineers.
“The turbocharged Ecotec 2.0L belongs on the list this year because it makes an outrageous 135 hp per liter in the Regal GS, and it’s a blast to drive,” said WardsAuto World Editor-in-Chief Drew Winter. “This engine delivers a level of power and sophistication that redefines Buick.”
The Regal GS achieves 0-60 mph in less than 6.7 seconds and runs the quarter-mile in 15.2 seconds at 98 mph. It also recently claimed victory in the 120-mph Grand Touring class at the Silver State Classic Challenge open road rally, with only a .019 deviation from a perfect time. A variation of the same engine powers the Regal Turbo.
For the record, Ward’s reviewed 35 engines from 15 automakers in this year’s competition. Winners were chosen based on several factors, including power; noise, vibration and harshness; fuel efficiency; new technology; and comparative data for similar engines.
The Ecotec 2.0L turbo engine includes the latest in technology combinations, whereby the turbo engine is an all-aluminum, dual overhead cam, four-valve design with forged steel connecting rods. The A356 aluminum cylinder head is cast using a rotocast process for high strength, reduced machining and improved port flow. The exhaust valves have sodium-filled stems that promote valve cooling."
