The annual Wörthersee festival in Austria is used by the Volkswagen Group to reveal performance-minded concept cars, and a new standout revealed this week takes the form of the Golf GTE Sport Concept. The vehicle has a lightweight shell made from carbon fiber while largely maintaining the familiar Golf hatch shape, though there’s a more aggressive stance complete with new gullwing doors. Power comes courtesy of a three-motor plug-in hybrid system, featuring a 1.6-liter turbocharged inline-four up front and an electric motor on each axle. Power output is rated at 396 horses, which propels the all-wheel-drive hatch to 62 mph in 4.3 seconds, and a top speed of 174 mph. Different drive modes range from full electric power to a traditional hybrid to full “GTE,” where the engine and both motors are utilized. Inside, there are two isolated capsules, each lined in carbon and microfiber materials. Racing bucket seats are equipped with five-point belts, and the instrument panel comprises three transparent displays, with the largest one displaying speed and current range.
