Audi Prologue Avant Concept points to the future of wagon design in Geneva [w/video]

The new generation Audi R8 and its LMS GT3 racing version are grabbing much of the attention at the Audi stand at the Geneva Motor Show. However, if you are more interested in seeing the brand's future design direction, just take a look at the Prologue Avant Concept that's also on display. Audi traditionally uses the Avant name for the company's wagons, but that's tweaked slightly here. The vehicle is certainly a five-door, but from some angles it looks more akin to a Porsche Panamera-like hatchback. Compared to the B-pillarless Prologue Coupe (that we recently drove), the stretched roof flows all the way to the angled rear hatch, and the result is a very elegant design. The interior tends towards minimalism with just a few screens showing the driving info. The Prologue Avant also ditches the Coupe's petrol-fueled hybrid for a 3.0-liter, twin-turbo diesel V6 plug-in hybrid with a total of 455 horsepower and 553 pound-feet of torque, which is linked to an eight-speed gearbox. Audi claims the setup reaches 62 miles per hour in 5.1 seconds and allows for 33 miles of pure electric driving. To get a sneak peek at what's next from Audi, take a look at the Prologue Avant Concept on the floor of the Geneva show in the gallery above.

Next Audi RS4 to get V6 turbo, US sales still unclear

Audi's high-performance S models have forged a reputation in the US for offering wonderful driving dynamics in a package that doesn't scream, "I bought a sport sedan." However, its even higher-performance RS models are still somewhat of a rarity here. While the RS5 and RS7 are in the current US lineup, many of the wild RS models that Europe gets, like the RS6 Avant (pictured above), never make it to these shores. Unfortunately, that might not be changing anytime soon with the next-gen RS4.
The RS4 will follow the lead of the next BMW M3/M4 and (rumored) next Mercedes-Benz C-Class AMG and make the switch to a smaller turbocharged powerplant. According to an Audi insider speaking to Car and Driver, the next RS4 will drop the last generation's 4.2-liter V8 in favor of a turbocharged V6. The engine block will likely be shared with the supercharged 3.0-liter V6 in the regular S4 but fitted with two turbochargers. Power would likely be around 400 horsepower to match the 425-hp M3 and rumored 450-hp C-Class AMG.
Unfortunately, the RS might not make it across the pond to our waiting hands because the source says no decision has been made to export them yet. Obviously, we hope that Audi makes the right decision and brings the next RS4 here.

Audi Q7 plug-in hybrid spied, Porsche powertrain possible

It's no secret that a new Audi Q7 is on the way. The replacement for the aging, three-row luxury CUV has already been spotted once, in December of 2013. Now, though, we have images of the second-generation model lapping Germany's Nürburgring Nordschleife, and it just happens to be showing a feature we reported on at the end of July - a plug-in-hybrid powertrain.
Given away by its high-voltage stickers on the window and a spare door to hide the charger - note how both the driver and passenger sides sport an access point - our spies snapped a series of photos, and put forth the compelling idea that the new Q7 would use the PHV system from the Porsche Cayenne S E-Hybrid.
If that's the case, that should mean at least 320 horsepower from a 3.0-liter, supercharged V6, while an electric motor chips in a further 95 ponies for a total system output of 416 hp.
