As much as we loved the Audi Prologue Concept that debuted late last year at the LA Auto Show – and, suffice it to say, we liked the first Prologue a lot – this new Prologue Avant from the German automaker may just rock our socks that much further off our feet.We have very little by way of actual, concrete details on what's under the angular wagon-shaped skin of the Prologue Avant, but we'd be perfectly content if it kept the previous two-door's 4.0-liter twin-turbo V8 in place underhood, augmented as it was when it was again shown at CES last month with a hybrid-assist system that put total system horsepower at 677, along with a meaty 701 pound-feet of torque. With all that power routed to all four wheels through an eight-speed automatic transmission, the 0-60 time of just 3.5 seconds strikes us as plenty quick.The powertrain details hardly seem the point of this new concept from Audi , in any case. Clearly, the big deal is the new bodywork, which builds upon the beautiful foundation of the original Prologue coupe with an elongated wagon shell and three additional doors (two rear doors and a rear hatch). The attractive body sits low to the ground on exaggerated 22-inch wheels, according to Auto Express . We note high-tech lighting elements front and rear and a modified front fascia with a bit more brightwork than the previous version.Assuming there's a bit of future reality baked into the Prologue Avant – which we believe is likely, considering that the coupe we salivated over in LA was said to point the way forward for the brand – it's safe to say we're in eager anticipation of the next several years at Audi . Have a good look at the images that have so far been released, and feel free to let us know what you think. We're sure Audi is interested in hearing your opinions, too.
