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.

Audi takes cars that park themselves to a whole new level

Autonomous cars are impressive displays of in-car technology, but what exactly would the benefit of such systems be for the average driver? Audi has answered that question by showing off its Piloted Parking system for the Audi Connect at CES 2013.
Installed on this Audi A7, Piloted Parking allows a driver to drop themselves off and have the car autonomously drive away on its own and find its own parking spot. The car can then later be retrieved by "calling" it back with a specially designed smartphone app. We'd be lying if we said this didn't bring back memories of Michael Knight summoning KITT with his wristwatch. The most impressive part of this car might be the fact that the car is fully autonomous but doesn't have any obvious sensors or monitors on the exterior of the car like many other self-driving cars have.

Audi will show all-electric 'sporty SUV' in Frankfurt

Audi is launching a fully electric crossover in 2018, and the brand is finally giving the world a look at what to expect with the E-Tron Quattro concept at the 2015 Frankfurt Motor Show. Previewed ahead of the event in these five sketches, the vehicle packs a heap of cutting-edge tech, including beautiful matrix laser OLED headlights, to be as efficient as possible. Audi maintains that it offers a range of over 311 miles, too. For such a green model, the design is surprisingly aggressive with a upright grille in front and angular panels elsewhere. The rear sketch shows the design tapering at the back to improve aerodynamics, though. Active aero parts at the front, sides, and rear further let the E-Tron Quattro concept slice through the air. When combined with a flat underbody, the drag coefficient is claimed to be a segment-best 0.25 cd. Audi also asserts the length is between a Q5 and Q7, which lends credence to speculation that the production version might be called the Q6. Underneath the muscular design is Audi's MLB 2 platform from the latest Q7. Three electric motors provide the all-wheel drive propulsion: one at the front and two on the rear axle. Located underneath the passenger compartment is a lithium-ion battery that uses cells from LG Chem and Samsung SDI. The interior seats four, and the driver is nestled into a wrap-around cockpit with a high center console. The front displays use OLEDs with gesture controls, and the rear passengers also get their own infotainment systems.

The brand is demonstrating this with the Audi e-tron quattro concept at the International Motor Show (IAA) 2015 in Frankfurt. The sporty SUV provides an outlook on the brand 's first large-series electric car. The Audi e-tron quattro concept is designed from the ground up as an electric car and proves to be pioneering in its segment at the very first glance. It follows the Audi "Aerosthetics" concept, combining technical measures for reducing aerodynamic drag with creative design solutions. Movable aerodynamic elements at the front, on the sides and at the rear improve the air flow around the car.
