Audi considering turbo option for longer, wider Hurac?n-based R8

The debut of the Lamborghini Huracán was (and remains) big news in and of itself, but equally as exciting is the imminent arrival of the Audi R8, which the Huracán presages. While the two will share a common architecture, don't expect that new R8 will simply be a cheaper version of the Huracán (like the current one arguably is to the Gallardo).
For one, the next R8 will be larger than the Huracán. According to emerging intelligence, Audi will make its sports car both longer and wider than the Lamborghini version. It'll also share the new Lambo's innovative carbon-fiber structure that will replace both the firewall and central tunnel. But to power it all, Audi will get more creative.
The next R8 will, like the current model and like the Huracán, offer a V10 engine at the top of the range. It will also offer the same 4.2-liter V8 as the outgoing model. But that won't be the end of the matter. Word has it that Audi is also working on a smaller, turbocharged engine to offer in certain markets that mandate smaller-capacity engines.

NHTSA awards Audi A3 and S3 sedans five stars

The Audi A3 and S3 sedans aced the New Car Assessment Program tests run by the National Highway Traffic Safety Administration, each scoring five stars overall. The A3 sedan adds this latest five-star rating to its Top Safety Pick+ award bestowed upon it by the Insurance Institute for Highway Safety earlier this year, and Audi says it's the only Euro premium luxury compact to do that double. The only place either car dropped a single star was for a male driver in the frontal barrier test and in the rollover test. It's clear from the lengthening list of top marks – and its list of safety technology – that it's among the safest sedans you can buy.

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.
