Read the BMW i8’s specs all day long and it’s still hard to believe the 1.5-liter, three-cylinder, hybrid-powered 2+2 coupe is capable of doing the things a proper sports car can do. Sure it’s turbocharged, but its still a three-cylinder! Remember the Geo Metro? Yeah, it was thee-banger and sported all of 55 horsepower. That’s what comes to mind when I hear three-cylinder.
