TCC’s Bottom Line
The 2017 Audi R8 balances thrilling power and handling with everyday livability. The 2017 Mercedes-AMG GT adds a few goodies this year before adding two new models to the lineup next year. 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.
