Audi prepping minor refresh for S6

Audi is well underway with testing for all of the refreshed versions of its A6-based sedan. We've already shown you shots of the Euro-spec A6 Allroad (which will wear some of its styling with our US-spec A6 sedan), and now we have some shots of a car that will actually arrive in the United States - the S6.
Like the Allroad, this will be quite a modest refresh, with tweaks to the headlights and taillights, as well as some slightly revised front and rear fascias. The headlights should get a new LED DRL pattern, although we doubt the changes will be much more drastic than that.
As with the Allroad, it seems likely that Audi will make a few very small changes to the interior, while the MMI infotainment system should also see an update. Changes under the hood, though, are more difficult to guess. That said, minor changes could be in store, but don't expect a dramatic increase in power or performance.

Next-gen Audi A7 design to be 'radical'

The Prologue concept has our attention. In fact, it has everyone's attention. It is the preview for the coming A7, and Autocar summarized Audi design chief Marc Lichte's concerning the new A7 as, "A more radical design is promised for the next-generation." In fact, the next A7 is said to become "the most radical" of three coming designs inspired by the Prologue, the others being the new A6 and A8. Autocar also said Lichte made it clear that there would be "much greater visual differentiation between the trio and other future Audis." Yet, for at least four years Audi has been talking about a design overhaul to fight back charges that its cars look too similar. In 2011 there was a "design initiative" dubbed AQR to make sure that "the design details will be different" between its hatchbacks, Quattro offerings and R Sports cars, and make proportion changes to its sedans. That didn't really move the needle. In 2013, then-design boss Wolfgang Egger hailed the end of "scalable design," a prime culprit for the 'same sausage, different lengths' accusations. We're not sure the needle moved much then, either. And this year came news of a new "Quattro-centric" design language that would stress horizontals, perhaps the new Q7 it's first serious proponent, a crossover that we'll have to see before we can judge. Although we've heard the bells ringing about fresh design at Audi for years, we hope they mean it with products that come after the Prologue; it is a fabulous place to start.

Audi reveals even more efficient 2015 R18 E-Tron Quattro

We've seen two of this year's LMP1 manufacturer challengers – Porsche's updated 919 Hybrid and Nissan's GT-R LM Nismo. Audi has finished cooking up the successor to its Le Mans champion and unveiled the fifth-generation R18 E-Tron Quattro, even better than before. The bodywork monocoque is carried over, but the body around it has been reshaped to improve airflow from front to rear with a new hood, front fenders and wheel arches, and radiator configuration. The engine cover behind the cockpit is shrunk more closely around the engine, and there are new headlights. The hybrid system can expend double the energy per lap this year, putting Audi in the four-megajoule class under the energy-use regulations. That extra energy will come from 17-percent more capacity built into the flywheel storage system and an electric motor good for 272 horsepower. The revisions haven't increased the weight of the car, pegged to the minimum allowed at 870 kilograms. They have, however, forced changes to the TDI engine, which has to use 2.5-percent less fuel per lap to offset the increased hybrid output. The 558-hp V6 has been optimized such that it "managed to more than compensate for the loss" of fuel allowed, and Audi expects "significantly" lower lap times this year and less fuel used. We're still waiting to see what Toyota has done to its World Endurance Championship-winning racer, but we're already looking forward to this year's Le Mans. It's going to be cracking. You'll find a press release below the videos with more info on the Audi.

In the FIA World Endurance Championship (WEC) and in the Le Mans 24 Hours as the season's pinnacle event, Audi is going to compete with a hybrid sports car in the 4-megajoule class. A twofold quantity of hybrid energy, fundamentally revised aerodynamics, the next step in lightweight design and a lot of detailed work characterize the fifth generation of the Audi R18. "The possibilities of the revolutionary regulations that have been in effect for LMP sports cars since 2014 are far from having been fully used.
