Buick Regal GS to have 270 horsepower
The 2012 Buick Regal GS will have 270hp and 295ft-lbs of torque when it arrives in dealerships this fall.
The Buick Regal GS will get all that horsepower and torque from a 2.0L turbocharged 4cyl Ecotec engine, and can be mated initially to a six-speed manual gearbox, while a six-speed automatic gearbox will be available later.
"The Regal GS 2.0L turbo delivers the highest specific output of any production engine GM has ever offered, and at 135hp per liter is the most power dense engine ever certified by SAE," said Mike Anderson, Ecotec global chief engineer and program manager.
Direct injection, continuously variable valve timing, and a twin-scroll turbo are some of the methods the little Ecotec engine uses to make such a big horsepower number. It also has a very flat torque curve, making 95% of its torque peak from 2300 to 4900 rpm. Yet, a five-year/100,000-mile powertrain warranty will be standard.
A four-wheel independent suspension with a four-link rear setup will have a lower ride height than other Regals, and will be adjustable through the Interactive Drive Control System, offering three different settings: Standard for all-around daily use, Sport for increased suspension tightness and steering response, and GS for full-fledged performance driving.
