TCC’s Bottom Line

No matter whether it's a coupe, convertible, or Gran Coupe, the 2014 BMW 6-Series covers soft and elegant as well as it does sharp and athletic.

The 2014 Maserati Quattroporte is staged to impress once more, with a selection of strong twin-turbo engines and a bold new look, inside and out.

The 2014 Mercedes-Benz CLS retains its fashion-forward look, while adding efficiency and, in AMG form, even more impressive performance.

TCC Likes

Exceptionally quick
Gran Coupe's extra doors
Convertible has well-executed lid

Bold new styling

TCC Dislikes

The scales don't lie
Steering still feels artificial, but better
Head room isn't great, anywhere

Poor gas mileage
Interior not as roomy as you'd expect

Rear-seat head room still tight
High price tag
Interior somewhat over-wrought
