Audi A3 E-Tron goes carbon neutral with German green electricity deal

Audi is proving that the fresh water flowing through the European Alps isn't just for bottling and drinking anymore. The German automaker struck a deal with Hamburg-based LichtBlick to offer buyers of the Audi A3 Sportback E-Tron a chance to get their electrical juice from all renewable-energy sources. That means all the power going into charging stations can come from hydroelectric power from Germany, Austria and Switzerland. The nuts and bolts part of it is that users pay the equivalent of about $12.30 a month plus 37 cents per kilowatt hour for the service. And LichtBlick is indeed legit, as it has been certified by TUV Nord for having at least one third of its power come from hydroelectric plants that are were built less than six years ago. Audi is looking to boost sales from a model it unveiled at last year's Geneva Motor Show. The car pairs a turbocharged 1.4-liter four-cylinder engine with an electric motor that combines for 250 horsepower. Most importantly, the A3 E-Tron gets a combined fuel economy rating of 157 miles per gallon. And while that figure comes from the more generous European driving cycle, it's impressive nevertheless. Check out Audi's press release below and read the Autoblog Quick Spin here. Audi and LichtBlick offer green electricity CO2-neutral mobility with Audi energy TUV-certified green electricity from the energy provider LichtBlick As an accompaniment to the market launch of the A3 e tron*, Audi is offering customers in Germany green electricity – Audi energy. The cooperating partner is the Hamburg energy provider LichtBlick SE. With Audi energy, the A3 e tron is totally emission-free when operated electrically. The power all comes from renewable energy sources and is generated exclusively at hydro-electric power stations in Germany, Austria and Switzerland. The Audi A3 e-tron can be recharged when parked at your home with Audi energy. At the same time, the entire household is supplied with eco-friendly electric power. Audi energy is currently available for a basic monthly fee of EUR 8.95 and 26.76 cents per kilowatt-hour. The origin and quality of the green electricity are certified by TUV Nord. The "OK power" seal of quality also confirms the expansion of power generation from renewable sources: at least one-third of the electricity comes from hydro-electric power plants less than six years old. Providers of this green electricity do not make use of federal subsidies pursuant to the German Renewable Energy Act (EEG).

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:

For Audi, Quattro name means something for hydrogen cars, too

Forget Dueling Banjos. Audi is proposing "Dueling Motors" for its Audi A7 Sportback H-Tron Quattro concept vehicle. All in the name of appropriate pickup, of course. The German automaker, which showed off the concept sedan at the Los Angeles Auto Show last month, is pairing a plug-in electric motor with a hydrogen fuel cell powertrain. Each motor powers two wheels, maintaining the Quattro's all-wheel-drive pedigree. The car's 8.8-kWh lithium-ion battery can drive the car as far as 31 miles on battery-power alone. After that, the water-vapor-spewing fuel-cell engine kicks in. Audi executive Ulrich Hackenberg told Automotive News Europe that the unusual set-up is necessary because the hydrogen fuel cell powertrain alone would only power two wheels while providing an insufficient 136 horsepower. Not exactly sport-sedan material, especially for a car that weighs about 4,300 pounds, even if it is a zero-emission ride. Combined, the two engines give the sedan 231 horsepower as well as a combined single-charge/full-tank range of almost 350 miles. What it all means is that the A7 can go from 0 to 60 miles per hour in less than eight seconds and has a top speed of about 112 miles per hour, and can still dash through the snow.
