I posted this in the Frankfurt but figured this really does deserve it's own thread as the similarities to what has been leaking about them using from the Dualnote. Weight you'll see is still very much an issue. Also check the full article as it will as it will probably be priced in full competition with Honda is talking.
"One of these ideas is demonstrated by the powertrain: The e-tron Spyder drives its rear wheels with a midship-mounted, twin-turbocharged diesel V-6 good for 300 hp and 480 lb-ft of torque. The front wheels are powered by a pair of electric motors that combine for 88 hp and 260 lb-ft. Audi is hopeful that, despite their extra weight, electric motors employed in this manner will make cars more agile, as they can apply torque with extreme precision and celerity.
We also tried out electric operation, which was by no means sluggish but not nearly as impressive as diesel mode. Combined diesel and electric propulsion wasn’t an option—it’s a concept car; that we were allowed to drive it at all is unusual. We loved it with the diesel alone, and can only guess how this car would scoot in theoretical production trim—more than 400 pounds lighter, with the diesel at full power and the extra assistance of the torquey electric motors. Audi says it could do 0 to 62 mph in 4.4 seconds and reach a governed top speed of 155 mph. Why not?
