Audi says 13% of A3 sales are E-Tron plug-in hybrids

Audi's most recent metric for plug-in sales of its A3 Sportback line brings up the classic "glass half full" or "glass half empty" conundrum. The German automaker says that almost 13 percent of its A3 sales during the past year have been of the E-Tron plug-in hybrid variety. That's a decent rate, and a notable one because Audi said late last year that it was hoping that as much as a quarter of its global sales will be plug-in vehicles by 2025. The 2017 model-year Audi A3 Sportback E-Tron has the same specs as the 2016 version, featuring a 1.4-liter engine paired with an electric motor that together deliver 204 horsepower and 258 lb-ft of torque. The 2016 version was rated by the Environmental Protection Agency (EPA) as having an 86 miles per gallon-equivalent rating, and was estimated to be able to go as far as 16 miles on electricity alone. Audi notes that the EPA hasn't yet rated the 2017 version, but we expect it to be the same. The plug-in hybrid can zip from 0 to 60 miles per hour in 7.6 seconds. As for that 13-percent figure, Audi didn't specify if that meant US or global sales. The company moved 19,622 A3s in the US through July. At 13 percent, Audi would've sold about 2,500 A3 plug-in hybrids. To put that in perspective, the Ford Fusion and C-Max Energi PHEVs have moved 8,576 and 8,155 units this year, respectively. Audi of America president Scott Keogh said on the eve of last year's Los Angeles Auto Show in November that he wanted 25 percent of Audi sales to be plug-ins by 2025. The following month, Audi said it was hitting that 25-percent threshold in Norway and the Netherlands, where citizens tend to be a bit more plug-in-centric than Americans. But it's a good start.

VW confirms Audi's emissions test transmission anomalies

Just a week after reports that the California Air Resources Board (CARB) found an emissions cheat in some Audi automatic transmission software programs, parent company Volkswagen has come clean. As reported by Reuters, VW's response to an article by Munich's Sueddeutsche Zeitung stated that the adaptive shift functionality can "lead to incorrect and non-reproducible results." Adaptive shift programs alter the characteristics of a vehicle's transmission to suit different driving styles. Gentle driving will result in earlier shifts and lower engine revs, while hard-charging on the pedals and steering will make the transmission more responsive and hold gears longer. That adaptation can change over time or even on a short-term basis. And it can save fuel. The difference in this case is that is seems that the Audi transmissions were specifically programmed to detect emissions test conditions. As we explained in a previous article, one of those test conditions is keeping the wheel straight. Turning more than 15 degrees shuts the test mode off. According to Reuters, the US government is trying to determine whether this classifies as an emissions cheat device, although VW, Audi, and the EPA have not commented on the record. This latest accusation is separate from the larger VW diesel emissions scandal. Related Video: Image Credit: Getty Editorial Government/Legal Green Audi Volkswagen Emissions vw diesel scandal

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.
