Recharge Wrap-up: Audi 'Plugging In' video, Citroen e-Mehari rumors

Audi is sponsoring the Newport Folk Festival with its "Plugging In" campaign. In celebration of the event, a video shows the history of the festival, and how plugging in the electric guitar changed music, similar to the way plugging in an electric vehicle changes the way we think about transportation. The video is focuses entirely on music, but at the end, we get the (ahem) plug from Audi: "Audi A3 Sportback e-tron — Plugging In Across America." Watch it above. The first image from Tesla's Firmware 7.0 update has made its way online. The photo shows what appears to be Tesla's new Autopilot feature. The view of the display also suggests that beta testing is happening on main roads between San Francisco and Tesla's home in the tech hub of Silicon Valley. See the photo and read more at Teslarati. The IRS has published a notice regarding its tax code overseeing the treatment of biodiesel credits. It says that, among other things, claimants must reduce their income tax deduction by the amount of the credits given for alternative fuel used or sold during a given quarter in 2014. Biodiesel producers and blenders were eligible for a tax credit of $1.00 per gallon. Read the notice from the IRS, or learn more from Biofuels Digest. Rumors suggest that Citroen will unveil a concept EV based on the C4 Cactus and classic Mehari at the Frankfurt Motor Show. L'Automobile Magazine is reporting that the French automaker has registered the name "e-Mehari," leading to speculation — and even a goofy rendering — from L'Automobile. There has been no official acknowledgement of the e-Mehari from Citroen, so let's not get too excited yet (especially you, Mr. Ewing).

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:

Audi A7 Sportback H-Tron Quattro packs plug-in hydrogen powertrain

If you think a plug-in diesel hybrid is an expensive proposition, just wait until you hear details about the just-revealed Audi A7 Sportback H-Tron Quattro. The "H" in H-Tron, as you might guess, stands for hydrogen, so say hello to a new concept that combines a plug-in battery system with a hydrogen fuel cell. Yeah, exactly. Let's start with the numbers. On the plug-in side, the new H-Tron has an 8.8-kWh lithium-ion battery that can power the car for up to 31 miles on battery power. With electric motors on both axles – it's a Quattro, after all, but a through-the-road hybrid with electronic torque distribution management – the A7 H-Tron uses a hydrogen fuel cell and four (!) H2 tanks to offer about 62 miles per gallon equivalent. Audi says the overall fuel cell stack efficiency is "as high as 60 percent" while the electric motors operate at 95 percent efficiency. Efficiently turning all of that electricity into movement means the A7 Sportback H-Tron Quattro has a total power output of 398.3 pound-feet of torque. The 4,299-pound concept can allegedly go from 0-62 miles per hour in 7.9 seconds and has a top speed of 112 mph. The car's total range is 311 miles. The A7 H-Tron is not the first plug-in hydrogen vehicle concept. That title goes to the Ford HySeries Edge. Mazda also considered putting a hydrogen range extender in the Mazda5 plug-in van. The Audi A7 Sportback h-tron quattro It sprints from 0 to 100 km/h (62.1 mi) in 7.9 seconds and on to a top speed of 180 km/h (111.8 mph). It covers over 500 kilometers (310.7 mi) on one tank of fuel – and its exhaust emits nothing more than a few drops of water: The A7 Sportback h-tron quattro, which Audi is unveiling at the Los Angeles Auto Show 2014, uses a powerful, sporty electric drive with a fuel cell as its energy source that operates in combination with a hybrid battery and an additional electric motor in the rear. The overall electrical system power of 170 kW is transferred to both the front and the rear wheels. This drive configuration makes the emission-free Audi A7 Sportback* a quattro through and through – a new departure in fuel cell cars. "The A7 Sportback h-tron quattro is a genuine Audi – at once sporty and efficient. Conceived as an e-quattro, its two electric motors drive all four wheels," explained Prof. Dr. Ulrich Hackenberg, Member of the Board of Management for Technical Development at Audi. "The h-tron concept car shows that we have mastered fuel cell technology.
