Under the Hood

The base engine in the Regal is a 2.4-liter four-cylinder that makes 182 horsepower. Buyers looking for more power can select the optional turbocharged 2.0-liter four-cylinder that's rated at 220 hp. The engines work with a six-speed automatic transmission to power the front wheels, and sedans with the turbo engine will also offer a six-speed manual gearbox.

Regals with the turbo engine can have Buick's Interactive Drive Control System, which equips the car with an adaptive suspension that automatically tailors itself to road conditions and driver behavior. IDCS includes three modes — Normal, Tour and Sport — that vary the response of the suspension, gas pedal, automatic transmission and steering system.
