Audi A3 E-Tron is a look at battery-operated things to come

Audi officially unveiled the A3 Sportback E-Tron at the 2013 Geneva Motor Show. While not a production model, the plug-in hybrid gives us a good glimpse at what the German automaker has in store for future products. The five-door gets around thanks to parallel hybrid drivetrain comprised of a turbocharged 1.4-liter four-cylinder engine and a small electric motor integrated into the vehicle's six-speed dual-clutch transmission. While the four-cylinder churns up 150 horsepower and 184 pound-feet of torque, the motor contributes 100 horsepower and 242 lb-ft of twist. All told, the design allows the E-Tron to serve up its full power from just 1,750 rpm.
An 8.8-kWh lithium-ion battery sits under the floor beneath the rear seat, complete with a liquid cooling system designed to keep the pack in its optimum temperature range. The A3 Sportback E-Tron can be charged in as little as 2.5 hours with a 3.6-kW charger, yielding an EV range of up to 31 miles. The machine can also travel using the electric motor, ICE or a combination of the two for a total range of 584 miles. Check out the full press release below.

Recharge Wrap-up: Electric Bayliner conversion, China considers EV mandates

An electric mobility enthusiast converted a Bayliner boat to electric power. Using 10 Tesla modules to build a 32-kWh battery pack, Scott Masterson's 2016 Bayliner 175 now uses an electric motor in place of the original 3.0-liter Mercruiser engine. With a top speed of about 53 mph and a range of about 25 miles, Masterson can enjoy a nice cruise on the water without the accompanying gas fumes. He says the conversion wasn't all that complicated, and it took him about three months of part-time work. Check it out in the video above, and read more at Electrek. Audi's updates to the 2017 A3 include the E-Tron plug-in hybrid. Inside the car, it will likely get Audi's "Virtual Cockpit" instrument display. The MMI infotainment system will be updated, with available Apple Carplay and Android Auto functionality. Slight changes to the headlights, taillights, and grille will make up the bulk of the exterior visual changes. Its powertrain will remain unaltered from the 2016 model, including its 83 MPGe combined rating and 16 miles of all-electric driving range. Read more at Green Car Reports. Hyundai has delivered its first hydrogen-powered car to Quebec. The Centre de Gestion de l'Equipment Roulant (Rolling Stock Management Center), which manages the province's government fleets, took delivery of a 2016 Hyundai Tucson Fuel Cell. It is leased in partnership with the University of Quebec's Hydrogen Research Institute of Trois-Rivieres, where the vehicle will be refueled. Read more from Green Car Congress. China is considering mandates for cleaner cars similar to those imposed by California. Unlike its current subsidy-based incentives, China could potentially require automakers to either produce or import more electric vehicles or purchase carbon credits from automakers that do. A draft of the legislation from the National Development and Reform Commission would fine non-compliant automakers at five times the price of the credits. "Without question, this will be good for the industry and will promote the development of all types of clean-energy vehicles," says China Association of Automobile Manufacturers Deputy Secretary General Ye Shengji. Compliance would be voluntary for smaller automakers. Read more from Automotive News.

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.
