Race Recap: 2013 Griffin King of the Hammers, and notes from a dry lake bed [w/video]

It was a local guy from 90 miles away who beat them all...
The image above shows 129 Ultra4 racing rigs lined up for the start of the 2013 Griffin King of the Hammers. In case you missed Part One that explains why they're there and why they might be doing the most difficult and absurd one-day off-road race in the world, check it out. After a week of races in other events and two days of qualifying for the big show, the men and women who made it in were lined up to do three laps of a course around the 140,000-acre Johnson Valley OHV area in California's San Bernardino County.

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.

Auto Express gets close-up look at the 2016 Audi R8

Audi invited Auto Express to the Ascari circuit in Spain to get a ride in the new R8 that will be introduced at the Geneva Motor Show. Jack Rix starts by giving us a walkaround of the camouflage-covered coupe, the obvious difference between it and the leaked image from a couple of weeks ago being the slatted front intakes. However, those intakes are present on the image Audi teased showing off one new, slimmer, laser headlight. The biggest shock: there will be no V8 model at launch - there will be one engine in two levels of tune. The first is the 5.2-liter R8 V10 with 540 horsepower, a bump of 15 hp over the present car. The second is the 5.2-liter R8 V10 Plus with 610 hp, a leap of 60 hp over the current model. That hotter trim, identified by its fixed rear wing, drops the 0-60 mile per hour time by a half-second to 3.2 seconds, and increases top speed seven miles per hour to 205 mph. Rix ran his fingers along the intakes behind the door and said he could feel sideblades, so all is not lost - what would an R8 be without sideblades? More obviously, on the V10 Plus Rix looked over there are new trapezoidal exhaust tips framing a serious diffuser in back. Underneath, the aluminum chassis adapted from the Lamborghini Huracan is 15 percent lighter than before and 40 percent stiffer. Shifting will be done via a seven-speed S-tronic dual-clutch transmission only. There are seven driving modes, a switchable exhaust note, and more direct variable steering. The German test driver Rix rode with said the new R8 is easier to drive faster, which - no matter what you think of the looks - will make it pretty special.
