Porsche built an electric Cayman concept that's surprisingly quick
Some of the most interesting cars never leave the concept phase. Porsche's latest EV is one of those. Porsche unveiled the Cayman E-volution concept at the 2017 Electric Vehicle Symposium. It packs an all-electric drivetrain that sends the car to 62 mph in just 3.3 seconds, more than a second quicker than the current 718 Cayman S. Its battery only lasts about 125 miles between charges, but that's fine, because it's never going into series production.
