The Car Connection's Take
TCC Rating
6.8
7.8
TCC’s Bottom Line
The 2017 BMW 6-Series is a luxurious jack of all trades (speed, style, comfort, and quality) but a master of one: grand touring. The 2017 Porsche 911 is a toe into the waters of modernity with a base turbo engine that gets good fuel economy. Don't be fooled; it's every bit the super car it always has been.
