Audi A8 Hybrid Concept

Audi A8 Hybrid Concept
Audi is calling its A8 Hybrid "the efficiency standard." And it's not exactly untrue since the top-of-the-peak, 211-horsepower 2.0-liter sedan boosted by a 45-hp electric motor has more power than an A3 TDI and a faster 0-60 sprint, yet the gas mileage comparison isn't unfavorable: the A3 gets 34 miles per gallon combined, the A8 Hybrid does 38 mpg. And you get all that A8 size and panache. And 21-inch rims. Responsibly.
