The Volkswagen Cross Coupe Concept is powered by a turbodiesel direct injection (TDI) engine (the report does not mention its capacity) with two electric motors. It allows the 1858kg (quite heavy) crossover coupe concept to make a total of 306PS of power. Torque figures have not been stated but VW TDI engines are pretty torquey. Couple that with two electric motors I believe that the car would make over 300Nm of torque more than enough to pull the Cross Coupe away from any other hybrid out there (aside from the occasional Fisker Karma or a Porsche Cayenne Hybrid).
Volkswagen is presenting the concept with a TDI plug-in hybrid (the VW Golf Plug-In Hybrid study -pictured below) in a world premiere at the Geneva International Motor Show (08 to 18 March 2012). Those who aren't aware, a plug-in hybrid means that one can use the power socket to charge up the batteries instead of waiting for the car's engine to kick in and charge the batteries.
It is quite an achievement considering the performance that you could get from the Cross Coupe. I however wish that Volkswagen would come up with an actual hybrid coupe concept instead of a crossover vehicle as I do not really fancy crossover type vehicles. And imagine if they'd actually make a lighter concept car with this powertrain setup, it could actually sip even less diesel.
