Audi R8, Lamborghini Huracan could get twin-charged five-cylinder

Engine downsizing and forced induction are some of the biggest trends in automotive powertrains today because. They offer the chance to reduce emissions and boost fuel economy, while possibly maintaining power. The shift is already happening to performance cars with turbocharged four-cylinders finding their way into the Ford Mustang, Chevrolet Camaro, and future Porsches. Now, there are rumblings of a tiny chance for a similar change coming for the Lamborghini Huracan and Audi R8. Why the new powertrain? China. While the market there might have slowing growth, it's still a major country for auto sales. The annual taxes on cars there also happen to be based on engine displacement, and there's a 40 percent rate on those over 4.0-liters, according to Car and Driver. The obvious answer to this conundrum is to build a smaller displacement, forced induction engine for the R8 and Huracan. Car and Driver points to the new turbocharged and electrically supercharged, 2.5-liter inline five-cylinder from the recent Audi TT Clubsport Turbo concept as a possible solution. Audi's e-turbo technology runs off a 48-volt electrical system and lithium-ion battery to produce a total of 600 horsepower and 479 pound-feet of torque in the prototype. With this mill, horsepower would barely shrink compared to the R8 V10 Plus and Lambo, but it actually makes more peak torque than their 5.2-liter V10s. While this is all theoretically feasible, take the possibility with a big grain of salt for now. According to Car and Driver, Quattro GmbH's Stephan Reil says that there's no work currently underway to fit the twin-charged five-cylinder, "but it has been talked about." That means such a vehicle is likely years away, if ever. In the meantime, a diesel version of the e-turbo setup is on the way the in the SQ7. Related Video:

Audi S3 with manual transmission still on table for US

The fine folks at Fourtitude recently sat down with Audi of America President Scott Keogh, and among other things, learned that the potent little S3 sedan could be offered with a manual transmission in the United States someday. That sort of sounds like the usual company line to us, but Keogh reportedly said the company is "looking very closely" at adding the manual to the S3, which currently is only available with a dual-clutch automatic.
Fourtitude also brought up the possibility of a hotter RS3 - a vehicle we've seen testing before, as a hatchback. We don't doubt that this more potent compact is already a done deal, but Keogh reportedly mentioned that the sedan will get this treatment. An RS3 for the US? Sign us up, for sure.
Head over to the Audi enthusiast site to read more from their talk with the company's US boss.

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).
