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 Mercedes-Benz SL Class feels content as a grand tourer, but it's sportier than you might expect.

The 2014 Porsche 911 range spans a broad spectrum, but somehow manages to hit exactly the right marks at each point, balancing performance, features, and practicality almost perfectly.

TCC Likes

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

Twin-turbo V-8's exceptional surge
Weight loss shows
Wide but supportive seats

Performance ranges from great to fantastic
Modern take on classic good looks
Comfortable, quiet interior

TCC Dislikes

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

ABC not as easy as 1-2-3
Less storage space behind seats
B&O bass isn't there

Electric power steering feel isn't quite 100%
Can get expensive in a hurry
Rear seat is cramped
