About the 2021 Mazda Mazda6
With an overall Carivo score of 8.0/10, the 2021 Mazda Mazda6 earns a Recommended rating among the sedans we've scored. Its strongest dimension is Reliability at 8.8/10, while Technology at 7.0/10 is where it trails the competition most noticeably. It's a solid all-rounder that delivers across most dimensions without obvious deal-breakers.
Reliability and safety are the two dimensions that matter most for long-term ownership costs. We rate the Mazda Mazda6's reliability at 8.8/10 — among the strongest in our sedan database, reflecting the nameplate's track record and recall history. On safety it earns 8.3/10: respectable, if not class-leading — several competitors bundle more driver-assist tech as standard. Check your trim's official ratings at nhtsa.gov.
Performance lands mid-pack at 7.4/10: enough power and composure for everyday needs, without the dynamics that distinguish the segment's driver-focused options. Technology comes in at 7.0/10 — functional and modern, with wireless connectivity and core ADAS features, though some competitors pack more standard tech at this price point.
Priced from $23,177–$27,182, 26 MPG, seating 5, the Mazda Mazda6 sits in the budget-friendly tier of the sedan market. The 8.2/10 value score is the headline: relative to what it costs, this sedan delivers more than most of the class. At 5 years old, it's worth checking whether a newer generation or refresh has addressed any weaker dimensions — compare it to the current model year before buying.
Bottom line: Think of the 2021 Mazda Mazda6 as the dependable pick rather than the exciting one. Shoppers who value predictability over headlines will be well served.
