VW is pursuing the holy grail in a super efficient SUV. The concept's plug-in diesel-electric powertrain is thoughtfully powerful, combining a TDI Clean Diesel engine with 2 electric motors to produce 305 horsepower and 516 lb-ft of torque, while still getting a remarkable 2.7 L/100 km in electric mode. With seating for six or seven, the three-row crossover will be targeted at those who want to carry everything they need, wherever they need to go.
