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 shows off the Prologue Avant Concept as a plug-in hybrid

The Audi Prologue Avant Concept goes in a different direction than the Prologue coupe, in more ways than just its five-door wagon body. The coupe was first shown at the LA Auto Show with a 4.0-liter, twin-turbo V8, then went redux at CES as a hybrid with a total of 677 horsepower and 701 pound-feet of torque. The only-slightly-larger Prologue Avant sticks with the hybrid but gets the system from the Q7 E-Tron quattro, meaning a 3.0-liter, twin-turbo V6 TDI with 353 hp and a 100-kW electric motor strapped to the eight-speed transmission. Total output is 455 hp and 553 lb-ft, pure electric range is 33 miles, and 0-62 miles per hour comes in 5.1 seconds. The forward section of cabin with its screen-based Tie Fighter displays and controls comes over from the coupe, as well as the four individual seats, but the Avant lavishes attention on rear passengers in ways not possible in the two-door. They also get a screen on the pass-through center console for convenience controls, and detachable OLED screens - a la the detachable tablets in the Q7 - with which they can send information to the front occupants. As a traditional Audi avant is to a coupe relative, the Prologue Avant is all about bringing the family along on the digital highway. We'll see it at the Geneva Motor Show next week, and Audi is again talking up how the design language will migrate to production cars. It also makes noises in the press release below about near-production many of the technologies are in the concept, so it looks like there could be all sorts of Easter Eggs on the way from the Ingolstadt brand.

Audi S5 spied

We only recently saw the next-gen Audi A5 testing for the first time with its sleeker design covered in camouflage. Now, here's a well-concealed glimpse at of the higher-performance S5 for comparison against the standard coupe. With so much swirling camouflage picking out the differences between the two models isn't easy, but there are a few tweaks to notice. The intakes on the front fascia are just a little bigger, hinting at the increase in power. The brakes also appear to be larger, especially when comparing them at the rear. Of course, the most obvious changes are the dual exhausts poking out each corner of the speculative S5. While more power is assured for the S5 over the A5, the exact powerplant isn't officially known yet. Rumors suggest Audi using a tuned version of the supercharged 3.0-liter V6 making between 340 horsepower and 350 hp, at least for the S4. The switch to the MLB Evo platform means less weight to haul around no matter what's under the hood, though. The next-gen A4 should provide some more hints about the future of the lineup when it launches at the Frankfurt Motor Show in September, and the coupes are expected to join the lineup later.
