Next Audi R8 to be up to 130 pounds lighter

"Simplify and add lightness," as Lotus founder Colin Chapman said. In a world where even supercars are subject to environmental, efficiency and emissions standards, lighter vehicles are being looked on as a sort of panacea - make it lighter, and it's automatically faster, more agile, easier to brake and better on gas.
Knowing this, it comes as no shock that Audi is looking at ways to lighten up its next-generation R8, with the brand's head of technical development Ulrich Hackenberg targeting a 110- to 130-pound diet for the mid-engine rocket. This supports previous reports regarding the focus for the next R8. Motor Trend reports that aluminum and carbon fiber feature heavily in plans for the next R8, which should go a long way toward slimming down even the lightest of R8s, the 3,678-pound V10 Plus model.
There's more over at Motor Trend, including the buff book's attempts to get Hackenberg to discuss powertrain options for the next R8.

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.

Weekly Recap: Audi pulls back the curtain on its future

The E-Tron Quattro concept is the future of Audi. It embodies all of the traits that will make the brand – and electric-powered luxury vehicles – more relevant into the 2020s. Here's why: The E-Tron Quattro concept, which will debut next month at the Frankfurt Motor Show, is a large sport utility vehicle that promises a range of 311 miles. It's an all-electric daily driver that fits the needs of most Americans. In production – which Audi says starts in 2018 – this vehicle will seat five and likely be called the Q6. You can take your family from Boston to Philadelphia without recharging. That's mainstream. We're moving away from the industry's "science experiment" era (as General Motors product chief Mark Reuss once described the appearance of the first gen-Chevy Volt) to a period where electric vehicles are plausible and practical for many US buyers. The 2018 Q6's only holdup for the masses will be price. But if you can afford an Audi SUV, you'll be able to buy an all-electric version. The E-Tron concept uses Volkswagen Group's second-generation modular longitudinal platform. The lithium-ion battery is located between the axles and below the cabin. Urquhart says the production model will feature the automaker's latest battery technology developed with LG Chem and Samsung. IHS Automotive projects the Q6 will sell more than 40,000 units annually by the end of the decade. "The E-Tron Quattro is a precursor for what will be an exciting and landmark production model for Audi and will position the brand at the forefront of the premium EV market," IHS analyst Tim Urquhart wrote in a commentary. It's the Tesla-zation of America. It's the Tesla-zation of America. The Q6 will be a Model X fighter, and expect other automakers to follow suit, particularly in the luxury sector with SUVs and other large vehicles. They offer more space for the battery packs, and development costs can be recovered easier. "Premium brands have an inbuilt advantage in terms of introducing [electric] powertrains over more mainstream automotive brands," Urquhart wrote. OTHER NEWS & NOTES Analyst says Tesla stock could be worth $465 a share Morgan Stanley analyst Adam Jonas sent shockwaves through the industry when he said Tesla stock has the potential to reach a whopping $465 a share. That's a leap from its $230.77 price at Friday's market close.
