The Car Connection's Take
TCC Rating
8.4
9.0
TCC’s Bottom Line
The 2014 BMW i8 is a new kind of sport coupe--an ultra-efficient one with advanced materials, electric and gas propulsion, and a lot more--and buyers will have to recalibrate their idea of what performance means to appreciate it fully. 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.
