Audi reveals even more efficient 2015 R18 E-Tron Quattro

We've seen two of this year's LMP1 manufacturer challengers – Porsche's updated 919 Hybrid and Nissan's GT-R LM Nismo. Audi has finished cooking up the successor to its Le Mans champion and unveiled the fifth-generation R18 E-Tron Quattro, even better than before. The bodywork monocoque is carried over, but the body around it has been reshaped to improve airflow from front to rear with a new hood, front fenders and wheel arches, and radiator configuration. The engine cover behind the cockpit is shrunk more closely around the engine, and there are new headlights. The hybrid system can expend double the energy per lap this year, putting Audi in the four-megajoule class under the energy-use regulations. That extra energy will come from 17-percent more capacity built into the flywheel storage system and an electric motor good for 272 horsepower. The revisions haven't increased the weight of the car, pegged to the minimum allowed at 870 kilograms. They have, however, forced changes to the TDI engine, which has to use 2.5-percent less fuel per lap to offset the increased hybrid output. The 558-hp V6 has been optimized such that it "managed to more than compensate for the loss" of fuel allowed, and Audi expects "significantly" lower lap times this year and less fuel used. We're still waiting to see what Toyota has done to its World Endurance Championship-winning racer, but we're already looking forward to this year's Le Mans. It's going to be cracking. You'll find a press release below the videos with more info on the Audi.

In the FIA World Endurance Championship (WEC) and in the Le Mans 24 Hours as the season's pinnacle event, Audi is going to compete with a hybrid sports car in the 4-megajoule class. A twofold quantity of hybrid energy, fundamentally revised aerodynamics, the next step in lightweight design and a lot of detailed work characterize the fifth generation of the Audi R18. "The possibilities of the revolutionary regulations that have been in effect for LMP sports cars since 2014 are far from having been fully used.

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.

Startup will make your Audi A4 self-driving for $10k [w/video]

We are on the cusp of the next generation of semi-autonomous driving technology becoming affordable. Adaptive cruise control is already trickling down to the mass market, and the more sophisticated systems found on vehicles like the Mercedes-Benz S-Class are clearly coming, as well. If you're a little adventurous, live in California and drive an Audi, you might be able to upgrade to the next stage of driverless tech even sooner. A San Francisco start-up called Cruise Automation is launching an aftermarket autopilot system called the RP1 for $10,000, with deliveries starting in 2015.
The RP1 is designed for 2012 and newer Audi A4 and S4 models. Although, Cruise CEO Kyle Vogt told Autoblog in an email: "There's no reason we can't expand to other cars, and we will." The system includes a sensor pod on the roof containing cameras, radar and other sensors to scan the road ahead. It then sends data to a small computer mounted on the side of the trunk. The desired inputs are then made by actuators for the steering, brakes and throttle to control the car. A button in the cabin activates the autopilot and controls the desired speed. Not completely unlike Audi's own, developmental, semiautonomous system.
At this point, the RP1 is somewhere between an adaptive cruise control system and an autonomous vehicle. It can control all of the cars inputs and even bring it down to a complete stop and then accelerate again. However, it only works on select highways in California. "We use geofencing to limit the areas of operation to segments of highway in which we've collected enough data to ensure our customers' safety," said Vogt to Autoblog.
