The short answer
Based on available data, the Mazda 6 comes out ahead of the Chevrolet Malibu on power. Check the specs table and owner sentiment below for the full comparison before deciding between the two. Both are covered by real owner reports on CarWizz.
Overall
Sentiment is sharply divided by generation and is heavily dependent on model year. The 2013 model year is universally panned, described as so poorly received that it required an emergency refresh for 2014 and was replaced by a new generation for 2016. The 2016+ generation (current) receives mixed to positive feedback, praised for being a quiet, comfortable highway cruiser with good fuel economy, modern features like Apple CarPlay, and representing strong value, especially when purchased used at a significant discount.
Best version to buy
2016+ Generation (specifically post-2013 refresh). Within this, the 2.0L turbo engine is mentioned as more robust and powerful, though the 1.5L turbo is more common.
