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.

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.

2017 Audi A4 Deep Dive

Unchanged. Plain. Boring. These words have been used to describe the new 2017 Audi A4, but they all miss the point entirely. Yes, the design of the new A4 is evolutionary, rather than a ground-up restyling. But as they say in ancient High German, "If it ain't broke, don't fix it." Of course, if you're at all interested in the 2017 Audi A4, you've probably read all about it in the official press release a few days ago. So we'll cut to the chase and tell you the bits you don't already know: the American-market details. We spent a day at Audi headquarters in Ingolstadt last week finding out the latest and poking around the A4 in the metal. The new A4 is wider, longer, and roomier than before. The lines are crisper and sharper, but yes, the proportions have remained very similar. That was done on purpose, thoughtfully. Not out of laziness. Stand any two sequential generations of Porsche 911 next to each other and you'll find they are rather similar. And yes, people do complain about that. But they also complain about the property tax rate on their third home in Monaco. That familiar-looking body gets a shockingly low coefficient of drag of just 0.23. The improvements in drag come from fine-tuning details down to the placement of the side mirror (now on the door, rather than the triangular window panel) and the contouring of the inner edge of the side mirror, which gets little vortex generating bumps to improve the turbulent airflow in that area, reducing drag. Attention to detail and refinement of a successful design – not boring, lazy repetition. Another notable departure in the styling of the new A4 is equally subtle, but even more significant from a precision manufacturing perspective: the hood has no cut lines on its upper surface. Instead, the hood now wraps around the tops of the fenders, the cut line integrating with the sharp crease that runs down the entire body side. The creation of this cut line requires extremely tight manufacturing tolerances to enable the precise alignment of the hood and fender gap with the stamped-in crease in the door panel; misalignment would be obvious and catastrophic to the clean, simple design's flow. Now, let's rip off this Band-Aid: no, we won't be getting the Avant. Why? Because no one buys it, vociferous vocalizations on the Internet aside.
