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.

Google poised to release Apple CarPlay rival this month

Apple and Google. They're the Michigan and Ohio State of the tech world. They're New York Yankees and the Boston Red Sox, Real Madrid and Barcelona, or whatever sports-based rivalry you want to cook up. Bottom line, if one company expands into a segment, it's only a matter of time before the other follows suit. And now, that rivalry is about to carry over to your car's dashboard.
Unnamed sources are reporting to Automotive News that Google will unveil its very own challenger to Apple's new CarPlay in-car operating system later this month at the Mountain View, CA company's annual developer conference. The system, allegedly called Google Auto Link, will be the first product to come from the Open Automotive Alliance, a partnership between Google, General Motors, Hyundai, Audi, Honda and hardware manufacturer NVIDIA.
The official announcement is expected to be made on either June 25 or 26, at the Google I/O conference in San Francisco. Expect to hear a lot more about Google Auto Link then.

Audi R8 V10 Plus vs. Renault Clio Cup racecar will make you go hmmm...

Match up a hot hatch with a supercar of the same vintage, and we'll tell you who will win every time. It's easy, really, as the supercar invariably features a more advanced suspension, stickier tires and most importantly, more power. What if the hot hatch is race prepped, though?
In that particular case, all bets are off. A circuit-tuned suspension, a stripped-down cabin, an ultra-quick sequential transmission and the greatest equalizer of them all, slick tires, are all that's needed to turn the typical hot hatch into a proper dragon slayer.
Perhaps seeking to prove this, Evo has put together an interesting head-to-head between the Audi R8 V10 and a race-prepared Renault Clio Cup. Host Dickie Meaden takes us through each car, highlighting the bits and bobs on both sides which should make this a tight competition. And boy, is this one tight.
