Not happy with letting Mercedes-Benz claim ownership of “World’s Most Powerful Four-Cylinder” title, Volkswagen has decided to create an absurd beast of a car. Their new hot hatch Golf R 400 Concept boasts performance that buries Benz’s AMG-enhanced CLA45 — although that car really exists in the real world, whereas the Golf R 400 is strictly a concept (although one that is within realms of reality). With its turbocharged 2.0L four-cylinder, the Golf R 400 would clock a 0-62 mph sprint in just 3.9 seconds en route to topping off at a blurring  174 mph — thanks to the VW’s 395 horsepower and 332 lb-ft of torque. That’s considerably more powerful than the CLA45’s 360 horses. The mighty 2.0L four-banger achieves such high power output thanks to the 400 PS of forced induction. Other notable bragging points include the 4MOTION all-wheel drive, an automatic six-speed dual-clutch gearbox with manual-shift capabilities, and its customized exterior (and interior) right down to the flare-winged wheel design homage to the Rally Golf of the 1980’s. Fuel efficiency has, quite literally, never been so powerful.
