Key features of the 2020 Mazda6

At first glance, it might seem the 2020 Kia Optima offers the best deal, with a $700 lower starting price than the 2020 Mazda6. However, this last model comes standard with a stronger powertrain and a larger list of features, most of which can only be found in the Optima when upgrading to higher trim levels.

Standard on the base Mazda6 sits a SKYACTIV®-G 2.5-liter 4-cylinder engine that comes paired with a 6-speed automatic transmission, producing up to 187 horsepower and 186 pound-feet of torque. The base Optima, on the other hand, gets powered by a 2.4-liter 4-cylinder powertrain that puts out 185 horsepower and 178 pound-feet of torque. Despite the difference in power, the Mazda6 is slightly more efficient than the Optima, achieving one more city mpg and the same highway mpg rating.

Both models offer stronger powertrains on higher trims. For the Mazda6, that means a SKYACTIV®-G 2.5-liter Dynamic Pressure Turbo engine that delivers up to 250 horsepower. The Kia Optima, for its part, gets either a 1.6-liter or a 2.0-liter turbocharged 4-cylinder engine, but neither of them can equal the power of the Mazda6.

When it comes to equipment, the 2020 Mazda6 also takes the win. Living up to the reputation that defines Mazda, this sedan features an upscale and well-equipped cabin aimed at delivering the most comfortable driving experience possible. Even the base trim boasts top-notch features, most of which can only be found on the Optima if you pay extra. These are some of the features that come standard across the board:

  • Smart Cruise Control
  • Dual-zone automatic climate control with pollen filter
  • Remote keyless entry system
  • Push button start
  • Leather-wrapped steering wheel and gear selector
  • LED Daytime Running Lights
  • HD Radio™

As you can see, both sedans are solid options in the market, but only the 2020 Mazda6 delivers such luxury-level features at a mass-market price. For more information on this model, do not hesitate to contact as at Cardenas Mazda. We would love to hear from you!
