2. Buick Regal GS
The Buick Regal GS easily passes for a comfortable, upscale sedan designed for daily commutes and leisurely drives.
However, beneath its refined exterior hides a spirited turbocharged 2.0-liter four-cylinder engine, delivering an impressive 259 horsepower and 295 lb-ft of torque.
Paired with its responsive handling and available all-wheel-drive system, the Regal GS rockets from 0-60 mph in just over six seconds—putting it within striking distance of the Mustang GT’s sub-five-second sprint.
With its subtle styling and unexpected quickness, the Regal GS is the perfect sleeper to catch Mustang drivers off guard at the stoplight.
