Audi TT Ultra Quattro Concept throws lightness at the problem

Audi is celebrating the 2013 Wörthersee Tour with a special concept version of the company's TT. The Audi TT Ultra Quattro concept tips the scales at just 2,449 pounds thanks to some extensive engineering work. The company pulled nearly 95 lbs from the car's body structure and used carbon-fiber reinforced plastics for many of its detachable body components. As a result, the concept weighs in at a full 220 pounds lighter than its production counterpart. Throw in a wicked turbocharged 2.0-liter four-cylinder engine with 310 horsepower and 295 pound-feet of torque, and you get a machine with the power to weight ratio in the supercar realm. 0-60 comes up in 4.2 seconds and top speed is listed at 173 mph.
Inside, the TT Ultra Quattro features plenty of carbon fiber trim, and designers also fitted the seats from the R8 GT to save a little weight. The buckets use CFRP for the seat frames, saving nearly 50 pounds in the process. In a world where automakers seem blind to the negative effect of throwing more heft at a vehicle, we're in love with the Ultra Quattro concept.

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.

Shuffle at Lamborghini sends CEO to Quattro GmbH

A management shakeup in Volkswagen Group's high-performance divisions will make Stephan Winkelmann (above) the new chief executive of Audi's Quattro GmbH on March 15. On the same day, former Scuderia Ferrari team principal Stefano Domenicali will replace Winkelmann as Lambo's boss. These changes are necessary because current Quattro chief Heinz Hollerweger is retiring. Rumors of these exact shifts cropped up in Italian media in December. Winkelmann began leading Lamborghini in 2005, and he has been at the helm for massive growth at the company. In 2015, the Italian supercar maker delivered a record 3,245 vehicles, and it had just set its previous best of 2,530 units in 2014. His new role at Quattro GmbH puts Winkelmann in charge of Audi's equivalent to M at BMW or AMG at Mercedes-Benz. The division is responsible for the Four Rings' R and RS production models, the Audi Sport customer racing program, and Audi Exclusive customization service. "In the future, the Audi Sport brand is to be positioned more clearly," the company's announcement said, which hints at one of Winkelmann's duties. Domenicali has been closely associated with Lamborghini rival Ferrari during his career and had years of experience within the automaker's racing team. He started in financing at the Prancing Horse in 1991 and moved to business planning for the Scuderia Ferrari F1 squad in 1993. He held many positions there and eventually ascended to the top as team principal in 2008. Domenicali resigned from leadership in 2014 because of the team's poor performance, but Audi quickly snapped him up as its as Vice President New Business. He now gets the reins of one of Italy's premiere supercar makers.

Winkelmann was President and CEO of Automobili Lamborghini S.p.A. since January 1, 2005. Heinz Hollerweger (62), the current Head of quattro GmbH, is to retire after almost 40 years of successful work for Audi. "With his experience from more than eleven years in charge of Lamborghini, Stephan Winkelmann will be a key contributor to the further growth of quattro GmbH," says Rupert Stadler, Chairman of the Board of Management of AUDI AG.
