This trouble did give us a good look under the hood, but the mess of wires and black plastic doesn't really reveal much. It's likely to have an updated version of the current GTI's 2.0-liter turbocharged inline four. We're hoping that Volkswagen will eventually bring us the 306-horsepower version from the European GTI Clubsport S.
Inside, we can see that the mule is a Mk7 model fitted with some updated equipment, most notably a new shifter, new HVAC controls and a new digital instrument cluster. Expect the new interior to better integrate controls for active safety equipment. Expect the full reveal sometime in 2019.
