BMW 2015 M4 Coupe

A high-performance sports car made with carbon fiber materials, this is sporty and eye-catching, with aggressive styling. At the same time, its a step forward in green. Instead of the gas-guzzling V8, it has a fuel-efficient, turbocharged six cylinder engine that packs plenty of pep. The use of aluminum and carbon fiber make for a far lighter vehicle that gets 25 percent better fuel efficiency than its predecessor. But judging from the cars dazzling appearance, no compromises were made to get there.
