If you think a plug-in diesel hybrid is an expensive proposition, just wait until you hear details about the just-revealed Audi A7 Sportback H-Tron Quattro. The "H" in H-Tron, as you might guess, stands for hydrogen, so say hello to a new concept that combines a plug-in battery system with a hydrogen fuel cell. Yeah, exactly.

Let's start with the numbers. On the plug-in side, the new H-Tron has an 8.8-kWh lithium-ion battery that can power the car for up to 31 miles on battery power. With electric motors on both axles - it's a Quattro, after all, but a through-the-road hybrid with electronic torque distribution management - the A7 H-Tron uses a hydrogen fuel cell and four (!) H2 tanks to offer about 62 miles per gallon equivalent. Audi says the overall fuel cell stack efficiency is "as high as 60 percent" while the electric motors operate at 95 percent efficiency.

Efficiently turning all of that electricity into movement means the A7 Sportback H-Tron Quattro has a total power output of 398.3 pound-feet of torque. The 4,299-pound concept can allegedly go from 0-62 miles per hour in 7.9 seconds and has a top speed of 112 mph. The car's total range is 311 miles.

The A7 H-Tron is not the first plug-in hydrogen vehicle concept. That title goes to the Ford HySeries Edge. Mazda also considered putting a hydrogen range extender in the Mazda5 plug-in van.Continue reading Audi A7 Sportback H-Tron Quattro packs plug-in hydrogen powertrain
