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).

2018 Audi SQ5 will use 48-volt electric supercharger

It seems like 48-volt electric systems and electric compressors are becoming relatively mainstream, and Audi will be adding another vehicle powered by this emerging technology in 2017, according to comments Audi powertrain chief Oliver Hoffman made to Autocar. Hoffman said the upcoming SQ5, probably a 2018-model-year vehicle, will use a version of the electric compressor technology that debuted on the SQ7. While the SQ7 uses two gas-driven turbochargers and one electric compressor, the SQ5 will likely only use one conventional turbo and one e-compressor. That should allow it to make 365 hp, but 390 hp is possible from the system and may hint at room for a more powerful SQ5 Plus down the road. Remember, the European SQ5 uses a 3.0-liter TDI engine, and that's the same basic engine that will power the new SQ5 with the addition of the new forced induction system and 48-volt electrics. And also remember that the US-market SQ5 uses a supercharged 3.0-liter gasoline engine, not the TDI unit, which is one of the reasons it's still on sale in the wake of the TDI scandal. Torque is the real differentiator: the current US-market SQ5 makes 354 hp and 347 lb-ft of torque, while the current Euro-market SQ5 Plus makes a massive 516 lb-ft. No word yet on how the dual-compressor system on the upcoming SQ5 will affect torque numbers, but expect the new engine to again have considerably more twist than its gas-powered US-market counterpart.

Audi says new 48 volt micro-hybrid system improves fuel economy, paves way for electrification

Most cars use a 12-volt system to power their electrical components. But, with more and more electric bits and bobs being added to new vehicles, a dozen volts is looking a bit weak these days. In fact, Audi says that standard 12-volt systems are being stretched "to their very limits." Enter 48 volts. If used in a car that gets 40 mpg, that would translate to around 43.5 mpg. Audi is testing a supplemental 48-volt electric system in two prototype vehicles – modified mild-hybrid versions of the A6 TDI and the RS 5 TDI – in order to add in more electric technology (an electric compressor, for example, to improve acceleration) and "convenience systems for dynamic chassis control." Audi says it has more applications in the pipeline, but the overall gist is that the German automaker sees 48 volts as an "important building block in electrification strategy." As you can see in the picture above (click to enlarge), the RS 5 TDI concept uses a li-ion battery installed in the back of the car and an alternator to provide 48 volts when the engine is off. Audi says that the 48-volt system can save up to 0.4 liters of fuel per 100 kilometers. To put that into US numbers, if used in a car that gets 40 miles per gallon today, that would translate into a bump up to around 43.5 mpg. The Advanced Lead Acid Battery Consortium (ALABC) is also working on a 48-volt system to improve fuel economy and we've got a deep dive of Audi's electric turbocharger here. Even more powerful and efficient – the new 48-volt technology from Audi Important building block in electrification strategy More voltage and more power for new technologies Scalable platform concept suitable for wide-ranging uses Ingolstadt, August 25, 2014 – Audi is to upgrade part of its vehicle electrical system from twelve to 48 volts. The move represents another technical building block for facilitating the integration of new automotive technologies while increasing the power and efficiency of its cars. "We are using the full bandwidth of electrification in our drive principles strategy. Running part of the vehicle electrical system at 48 volts plays a central role in this," commented Prof. Dr. Ulrich Hackenberg, Member of the Board of Management for Technical Development at Audi. "It enables us to make more energy available.
