Coming four years after the introduction of the radical hardtop version of the BMW i8, the plug-in hybrid sports car is now realized as an open top vehicle. Debuting for the 2019 model year, the BMW i8 Roadster provides a most adventurous manner to experience a electric/gasoline powertrain. Featuring a unique "Roadster" C-pillar, this latest take on the BMW i sub brand incorporates a convertible soft top that opens or retracts in 15 seconds. Equipped with a BMW electric motor at the front and a three-cylinder gasoline engine at the rear, the 2019 i8 Roadster is influenced by 374 horsepower and 420 lb-ft of torque. Starting price for the 2019 BMW i8 Roadster is slated at $163,300 in the United States.
