Once, 3.0 liter V6 and V8 engines ruled. Now, one 2.0 liter turbocharged engine is taking them on, and winning. This powerplant, stuffed inside a gorgeous 2011 Buick Regal CXL Turbo (which just so happens to be available at Ferguson Superstore - 1501 N Elm Place in Broken Arrow, OK), is taking the automotive world by storm. All thanks to GM, and a make that almost ceased to exist.

The 2011 Buick Regal CXL Turbo is a front-drive, entry-luxury sedan that comes in under $30,000. It is taking on similar, turbocharged competition from both foreign and domestic makes. Regal packs a nice amount of miles per gallon as well - rated at 18 city, 28 mpg highway, with top-notch handling and style which is sure to become classic.
The CXL Turbo "twists the front half-shafts with 220 hp and 258 pound-feet of torque," according to WSJ Online. What separates CXL Turbo from traditional Regal variants is its power - The car's 110 hp per liter of displacement is "kind of astonishing." We couldn't agree more.1

Also coming this Fall is the Regal GS, which will contain a more powerful V6 rated at 270 hp with the same displacement.
Decades ago, a man named Ferrari implemented smaller, turbocharged engines into his race cars. These motors went on to win F1 championships - I guess Buick knows where to put its money.
