Audi Quattro tech shoots for the moon

Most automakers seem satisfied building vehicles to drive on the Earth's surface. But not Audi. The German automaker is quite literally shooting for the moon with the vehicle you see here. Called the Audi Lunar Quattro, it forms what promises to be an integral part of one team's campaign for the Google Lunar Xprize. That team calls itself Part-Time Scientists, and is the only German contingent of the 25 that originally entered from around the world and the 15 that are still in the race. Sponsored and technically assisted by Audi, the Lunar Quattro is a solar-powered moon rover. It packs an adjustable solar panel and a lithium-ion battery powering four individual hub motors – one in each wheel. It can only travel at a theoretical maximum of 2.2 miles per hour, but outright speed isn't the point here. It's been designed to traverse the difficult terrain of the moon's finely dusted and craggy surface. It'll need to travel at least 500 meters (1,640 feet) and will transmit high-definition video footage from the twin stereoscopic camera on its swiveling head back to Earth. The lunar rover is scheduled to be launched aboard a rocket from Earth to the moon by the end of 2017. The 240,000-mile trip will take five days and is targeted to land north of the moon's equator – close to the place where Apollo 17 (NASA's last manned lunar mission) landed back in 1972. Before that, though, it'll be presented by Audi sales chief Luca de Meo (who's since been named the head of Seat) at the Cannes Innovations Days forum. You can check it out in the gallery and extensive press release below, but first, we suggest you watch the video playlist above while preparing to check out tonight's red moon eclipse.

The group of German engineers are working within the framework of the Google Lunar XPRIZE competition to transport an unmanned rover onto Earth's natural satellite. Audi is supporting the Part-Time Scientists with its know-how in several fields of technology – from quattro drive and lightweight construction to electric mobility and piloted driving. The moon rover will be named the "Audi lunar quattro." "The concept of a privately financed mission to the moon is fascinating," says Luca de Meo, Audi Board Member for Sales and Marketing. "And innovative ideas need supporters that promote them.

Audi S8 Plus packs 605 horsepower

Audi doesn't offer an RS 8, and probably never will. But with the release of the new S8 Plus, we wonder if it will ever have to. Because Ingolstadt's new flagship performance sedan packs a mighty punch. "Plus" doesn't even begin to describe the enhancements Audi and Quattro GmbH have wrought on the ultimate new version of the A8 sedan. Power is increased from 520 horsepower to 605, besting anything else in its class. Only the Mercedes S65, which packs four more cylinders and two additional liters of displacement, offers more horsepower. Torque is quoted at 516 lb-ft – a gain of 35 – and can deliver up to as much as 553 lb-ft in overboost. That bests any eight-cylinder performance sedan save the S63. The force-fed V8s in the Jaguar XJR, Maserati Quattroporte, and outgoing Alpina B7 don't stand a chance. All that muscle translates to a 0-62 time quoted at 3.8 seconds. Top speed is governed as usual to 155 miles per hour, but can be derestricted to nearly 190 with the Dynamic package that comes standard in Germany – one of the few places where top speed actually matters. Carbon-ceramic brakes keep all that power and pace in check, nestled inside 21-inch wheels. Naturally, Audi gives the S8 Plus a wide array of visual upgrades inside and out to set it apart from "lesser" versions, and is offering it in an exclusive matte silver finish. Of course none of those enhancements come cheap. In its home market come the end of November, Audi will charge 145,200 euros for the S8 Plus, representing a 28k premium over the existing S8. That also places this as the new top of the line, commanding a higher price than even the long-wheelbase, dozen-cylinder A8 L W12. We're waiting on word as to whether Audi will bring the new S8 Plus to America, where it would likely similarly cost over $140k. The pinnacle of sportiness – the new Audi S8 plus - Highest powered sport sedan in the premium segment - 4.0 TFSI engine outputs 445 kW (605 hp) and up to 750 Nm (553.2 lb ft) - Zero to 100 km/h (62.1 mph) in 3.8 seconds; top speed of up to 305 km/h (189.5 mph). Audi is making a strong statement with the new S8 plus*. With a power output of 445 kW (605 hp) and a top speed of up to 305 km/h (189.5 mph), the new Audi S8 plus* delivers even more enhanced driving performance. The new top model is reinforcing the brand's position in the segment of premium class sedans. "We have further sharpened our large sport sedan," says Prof. Dr.

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.
