Main Differences Between the 2020 Mazda6 and 2020 Nissan Altima 

At the base level, the 2020 Mazda6 and the 2020 Nissan Altima each use a 2.5-liter inline 4-cylinder engine, leaving them deadlocked for power ratings.

  • Mazda6 – 2.5L SKYACTIV®-G – 187 hp, 186 lb-ft
  • Altima – 2.5L inline – 188 hp, 180 lb-ft

On the highest trim levels, Altima drivers can opt for a 2.0L turbo for an extra price. The Mazda6 comes ready to meet the challenge with a turbocharged version of the 2.5L SKYACTIV®-G engine standard on Grand Touring, Grand Touring Reserve and Signature models.

  • Mazda6 – 2.5L SKYACTIV®-G turbo – 250 hp, 310 lb-ft
  • Altima – 2.0L inline turbo – 248 hp, 273 lb-ft

The Nissan Altima eagerly safeguards from impact with forward collision warning and automatic emergency braking, but the Mazda6 manages to work a full roster of active safety systems into the base price. All Mazda6 entries enjoy those technologies, plus standard pedestrian detection, adaptive cruise control, lane-keep assist, blind-spot monitoring and rear cross-traffic assist.
