Consumer Reviews for the Mazda 6
Read recent reviews for the Mazda 6
What a difference 4 model years make
Mike G. , 01/01/2020
2020 Mazda 6 Grand Touring 4dr Sedan (2.5L 4cyl Turbo 6A)
I previously owned a white 2016 Mazda 6 Touring. Due to an driver's fail to yield, my car was totalled back in late November. I checked out a blue 2020 Mazda 6. Everything I liked about the 2016 was there, with more, including improvements.
I bought the Grand Touring model. The turbo is a great improvement over the base engine. It's not a rocket by any means, but still lots of low end … torque to get you moving. Under normal driving, the turbo engine seems a bit smoother and more quiet than the base engine too. In fact, going from the 2016 to the 2020, the whole ride seems more compliant and quieter. I don't notice road imperfections near as much as in my '16. The steering is a bit easier while still communicating the feel of the tires against the pavement. There also seems to be improvement in the seats. A bit more padding and thigh support. Great for long trips. The interior itself has been greatly improved in those 4 years. Very sharp looking.
I won't go into detail about all the safety features since they are covered in multiple reviews. Suffice to say it was a good move for Mazda to make their whole safety suite standard across all trims. That wasn't the case in 2016.
One piece of advice. The only difference between the 2019 and 2020 model years is a new keyfob design and some badging on the Signature trim. That's it. If you can find the color and trim you like in a 2019 model, then go for it. It has a higher rebate available plus you're more likely to get a better deal since all their 2020 models have been coming in. No dealers in my area had the dark blue exterior/black interior combination that I wanted in a 2019. Hence, I ended up with a 2020. Also, I personally would start with the Grand Touring and go up from there. The Grand Touring is the lowest priced trim that has the turbo engine. A good upgrade going from 186hp/186ft-lb to 250hp on premium/310ft-lb.
To wrap this up, I'm very happy with my choice. If you're up in the air about which mid sized sedan to pick, at least have the Mazda 6 on your list of cars to pick from. It may not have the sales numbers that the Camry or Accord have, but it's a very capable and competitive sedan. If you want a great looking and great handling mid sized vehicle, this might be the one.
