These are the first official images of Audi's Prologue Avant concept car, revealed here ahead of next week's Geneva Motor Show.

Just four months after showcasing the massive Prologue Coupe at the LA Motor Show, here is a version that looks quite a lot like it but for one key difference; this time around, ladies and gentlemen, we have a boot.

Yep, shooting brakes are all the rage these days, and Audi has transferred the coupe's svelte lines onto a slightly more commodious bodyshape. It's a big bodyshape too, this car measuring in at 5.1m long, and 1.97m wide, it's a monster, five-door car with space only for four. Well, it is a concept.

What's less concepty is the drivetrain, which is taken from the Q7 plug-in hybrid, here turned up a notch. So you get a 3.0-litre TDI engine in combination with an electric motor that makes a total of 448bhp and a whopping 553lb ft of torque, which is allied to an eight-speed auto 'box and four-wheel-drive. Which means a 0-62mph time of just 5.1 seconds, and limited top speed of 155mph. All this in a car that, we're guessing, weighs near enough two tonnes.

Should you wish to run it purely on electric mode, Audi is predicting a range of around 33.6 miles. Underneath there's also adaptive air suspension, lightweight wishbones, 20in ceramic brake discs and four-wheel-steering.

And like the Prologue Coupe, this Avant also previews the future of Audi's design, with Audi's stunning new Matrix [frickin'] Laser lights, a new grille for a wider presence, wide shoulders, flared arches, and of course, the concept car staple - monster 22in wheels.

Inside it's all Luxury Skynet: much leather and Alcantara, a three-display touchscreen dash that forms one singular whole across the front, while at the back there are a pair of detachable OLED displays in the rear headrests. There's a display on the centre tunnel too for things like air con and infotainment, and front and rear passengers can exchange info. If you want to that is.

Then there's the 'butler' system, that identifies the driver by their smartphone, and adjusts the seats and climate control automatically according to your preset preference. That's cool, you have to admit.

In fact, the entire concept is cool; we've always been fans of wagons here on TG. What do you think of this one, dot.commers?
