With swan-wing doors, a shark-nose front end, and a supercar stance, the i8 plug-in hybrid is BMW’s most revolutionary car in decades. The interior seats four in trappings worthy of an Ian Schrager hotel. A turbocharged three-cylinder engine/electric motor duo with a combined 357 hp delivers M3-like acceleration, a 155-mph top speed, and Prius-like efficiency. Handling is agile and steering precise; braking is great for any car, let alone a hybrid. Overall, it’s a seriously impressive effort.
