The Car Connection's Take
TCC Rating
7.6
7.8
TCC’s Bottom Line
The 2017 BMW i8 is a stunning coupe with gull-wing doors that hides a slew of advanced technology, though the design may render its energy-efficient plug-in hybrid powertrain all but irrelevant. 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.
