GM's Ecotec Supercharged and 2.8 V-6 Turbo Recognized in Ward's 10-Best Engines

December 13, 2005

PONTIAC, MI — Two of General Motors’ newest, high-performance overhead cam engines — the 2.0L Ecotec Supercharged and 2.8L V-6 Turbo — have been named among the industry’s 10 best engines of 2006 by the editors at Ward’s Communications. Both engines are variants from two of GM’s most popular global, modular engine families, designed, engineered, and produced around the world. They also share a similar attribute, which Ward’s noted as an important development occurring in the industry today: forced induction. The Ecotec 2.0L supercharged is a variant of GM’s global Ecotec family, which features an aluminum block, inline four-cylinder, dual overhead cam, four-valve-per-cylinder engine design with 205 horsepower at 5600 rpm and 200 lb.-ft. of torque at 4400 rpm. At the heart of the Ecotec super-charged is an Eaton M62 helical roots-type supercharger. Maximum supercharger boost pressure is 12 pounds, and the system includes an air-to-water intercooler to increase intake-charge density, which in turn enhances power and reduces a supercharged engine’s propensity to “knock” at high boost levels. The 2.8L V-6 Turbo is the newest addition to GM’s V-6 engine family. All engines in the global V-6 family share traits that include a 60-degree lightweight aluminum cylinder block with iron cylinder sleeves, an aluminum structural oil pan and aluminum cylinder heads, dual overhead camshafts, and four valves per cylinder. The 2.8L V-6 Turbo delivers 250 horsepower at 5500 rpm and 258 lb-ft of torque from 2000-4800 rpm.
