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.

TCC Likes

Sleek coupe looks
Unparalleled fuel efficiency
Calm all-electric running in town

Performance ranges from great to fantastic
Modern take on classic good looks
Comfortable, quiet interior

TCC Dislikes

Pricey for its performance
Interior hardly luxurious
Could suffer from nerd factor

Electric power steering feel isn't quite 100%
Can get expensive in a hurry
Rear seat is cramped
