What we're driving: 2021 Mazda6 Carbon edition

This week I'm driving the 2021 Mazda6 Carbon edition, the most fun I've had in a midsize sedan in a while.

The big picture: Sedans are passé these days, as most buyers are gravitating toward SUVs and crossovers. Even so, Mazda is by far the most fun-to-drive car in its segment — engaging and athletic yet also quiet and refined.

• The Carbon Edition is a new appearance package, featuring an exclusive Polymetal Gray paint job, coupled with a striking red leather interior, that makes a great-looking car even better.

Yes, but: Unlike most midsize sedans, it doesn't offer a hybrid option.

• Instead there are two engine choices: the 187-horsepower standard four-cylinder, or a turbocharged option for up to 250 horsepower.
• The base engine gets an EPA-rated 26 mpg in the city and 35 mpg on the highway, while the turbo gets 23 mpg city/31 mpg highway.

Inside, the Mazda6 feels upscale, especially in the $33,745 Carbon Edition I drove.

• Every Mazda 6 now has Apple CarPlay and Android Auto, with wireless connectivity in the more expensive versions.
• Still, I'm not a fan of the controls in Mazda's entertainment system, or the layers of commands to merely change radio stations.
• It's been my ongoing gripe about Mazdas, which I otherwise love.

Standard driver assistance features include forward-collision warning, automated emergency braking, blind-spot monitoring and rear-cross-traffic alert.

• Lane-departure warning and lane-keeping assist are optional, while rear braking assistance and a driver-attention monitor are only available on the $37,000 Signature model.
