The Car Connection's Take
TCC Rating
8.4
9.0
TCC’s Bottom Line
The 2015 BMW i8 is a ground-breaking new sports coupe with a plug-in hybrid powertrain that delivers several driving personalities from which the driver can choose. 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.
