Audi R8 E-Tron back on production map thanks to new battery tech?

Contrary to our October 2012 report, it appears Audi's R8 E-Tron program is back on track, if a report from Australia is to be believed. Drive is reporting that the German brand has changed its mind and won't be sacking the program, despite previously stated concerns about the quality and price of batteries for the R8-based EV.
We last saw the R8 E-Tron prototype in the snows of northern Europe, although footage of the car has been non-existent since that wintry test. This new report claims that a small number of R8 E-Trons will see production, which gels with what we heard back in 2012 and supposed earlier this year. Apparently, some new sort of lithium-ion battery technology has allowed for a drastic increase in range, with rumors of the original 130 miles going up to around 250. According to Drive, this makes the project feasible again.
"Our engineers and technicians are further developing the car and its electric drive system. The range has grown significantly, allowing the potential for a small-scale production," an unnamed, but high-ranking Audi employee told the Aussies.

Audi Prologue concept drives itself to CES with updated powertrain

What's the point in crafting a one-off concept car if it only gets to stand in the spotlight at one show? That's what automakers have been asking themselves recently, and the answer has, generally speaking, been to repaint their show cars, give them a bit of new tech and put them back on center stage. And the latest to do so is Audi, which has given its Prologue concept a new lease on life. The Prologue was originally unveiled at the Los Angeles Auto Show less than two months ago, showing the way forward for the future of Audi design, in an elegant coupe form that looked ready to take on the Mercedes S-Class Coupe. We even got a chance to drive it around the streets of LA, and when we did, we marveled at the concept's advanced infotainment system that caters a range of personal preferences according to who's on board. "It's easy to see how this could even reach for chauffeured, or autonomously driven vehicles" in the future, we said at the time. And it turns out Audi was on the same page. At CES this year, Audi has brought back the Prologue concept, given it a darker coat of grey paint, a grey-tone interior (instead of the previous shades of brown and tan), a fresh set of wheels and equipped it with the autonomous tech the German automaker has been at the forefront of developing. Though other automakers have been fitting their self-driving prototypes with all-electric powertrains, Audi kept the 4.0-liter twin-turbo V8 in place – but fitted it with a hybrid assist to drive output up from an already prodigious 605 horsepower and 516 pound-feet of torque to an even more impressive 677 hp and 701 lb-ft, dropping the 0-62 time down to 3.5 seconds. Now that's the kind of "piloted driving" tech (as Audi calls it) that we can get behind.

The hottest modern sports cars rendered as rally racers

The modern-day World Rally Championship a monumental amount of fun to watch – I should know, as I recently was lucky enough to head to the UK to watch WRC Wales Rally GB – but even the most monstrous of the current WRC cars are based on fairly pedestrian European hatchbacks. Back in the heyday of rally, the Group B era in the 1980s, much hotter cars were the basis of even more incredible competition machines, for the most part. Take the exotic Ford RS200, or the Lancia Delta S4 with its twin-charged engine. And the hatchback-based Group B cars were bonkers, too. So what would some of our favorite modern cars look like if Group B had never ended? A British site named CarWow hired an artist to reimagine everything from the Rolls-Royce Wraith to the Porsche 911 as a retro-inspired rally car, and they were kind enough to let us share the results in the gallery above. The gallery features an Alfa Romeo Giulia in Martini livery, an Audi TT in classic Ur-Quattro colors, a Fiat 500 Abarth sporting massive flares and a hood blister full of auxiliary lights, a new Ford Mustang in RS200 livery, a Lancia Delta in Alitalia colors, a Porsche 911 in Rothmans livery, a Renault-Alpine in classic blue, a Rolls-Royce Wraith tribute to the Jules cologne Corniche Coupe, and a relatively modern-looking VW Touran. So far, the favorite around the office is the incredible Mercedes-Benz S-Class that is an homage to the wonderful 300 SEL 6.8 AMG "Red Pig" that essentially put AMG on the map. Check out the gallery above and see which one you like the best. Related Video:
