"Buick" and "sports sedan" can now officially live in the same sentence. The Buick Regal, refreshed with a revamped powertrain for 2014, now ranks among the top upscale sports sedans tested by Consumer Reports, just behind the BMW 328i but high enough to easily top the magazine’s road test scores for the Cadillac ATS and CTS sedans. The magazine, in its September issue, also gives Volvo S60 top marks.
