So I just stumbled upon another early review of the Q7 e-tron and it seems to deliver on everything you'd expect from Audi. Apparently this one of the only green vehicles that doesn't feel like its had to make compromises to be one. It is the only diesel option in the plug-in hybrid SUV segment. Its rumored to deliver 157 mpg but considering its two and half tonne weight, id expect the real world numbers to be significantly lower. Its hybrid powertrain is good for 369bhp and 516lb ft, enough to get it from 0-62mph in 6.2 seconds, with a top speed of 143mph.

Glad to see this happening after so many years of GM having hybrid versions of its big SUV's on the market, then recently we had Porsche with its hybrid Cayenne. Just like how the Cayenne was a success in its own right, i think the Q7 will be too.
