2013 Buick Regal: What's New, Specs & Features

Last updated August 4, 2026

The 2013 Buick Regal is a light-update model, not a redesign. Its biggest change is that the fuel-saving 2.4-liter eAssist mild-hybrid powertrain replaces the regular 2.4-liter engine on non-turbo Regals.

About the 2013 Buick Regal

2011-2017 Regal generation, third model year and last year before the 2014 refresh.

Buick positions the Regal as a quieter, more upscale midsize sedan with a more European road feel than older Buicks. The lineup gives buyers three clear personalities: fuel-saving eAssist models, stronger 2.0-liter turbo models, and the harder-edged GS. Across the range, the pitch is comfort, a well-finished cabin, and more driver involvement than a typical family sedan, aimed at buyers who might also look at cars like the Acura TSX or Audi A4.

Buick positions the non-turbo Regal as an efficient, well-equipped sedan, with eAssist plus features such as heated leather-appointed seats and dual-zone climate control. The Turbo Premium trims emphasize stronger performance, while the 270-hp GS adds an adaptive suspension, Brembo front brakes, sport seats, and bi-xenon headlights.
