Audi calls R18 E-Tron Quattro its 'most complex race car'

Technically speaking, Audi's R18 E-Tron Quattro is quite technical. The German automaker says the diesel-hybrid is the "most complex race car" it's ever created. And we'll take their word for it. The Audi, which pairs a V6 turbodiesel powering the rear wheels with two electric motors, is all about connectivity, giving the car's crew the opportunity to constantly monitor the vehicle while it's racing. The car sends in a host of data each lap to the crew's computers, and the vehicle's telemetry system constantly keeps tabs on things like hybrid energy levels, cockpit temperature and boost-pressure levels. In all, the amount of data parameters is more than 100 times greater than in 1989, when Audi first tested a race car equipped with automatic data transmission capabilities. Audi first released specs on the updated version of the R18 E-Tron Quattro late last year, trumpeting the vehicle's advantages in competing in the LMP1 class of the 2014 World Endurance Championship (WEC). Audi made the car a little narrower and a little taller and it complies with a new WEC regulation requiring the front end set off by a new wing. Take a look at Audi's most recent press release below. AUDI R18 E-TRON QUATTRO WITH COMPLEX ELECTRONIC ARCHITECTURE • Telemetry connection between race car and pit lane • Permanent acquisition of far more than 1,000 parameters • Various electronic control units interlinked by a multitude of CAN Bus systems Ingolstadt, May 5, 2014 – The Audi R18 e-tron quattro is the most complex race car created in Ingolstadt and Neckarsulm to date. This not only applies to the mechanics. The electronics of the most recent LMP1 race car with the four rings is more sophisticated than ever before. The age of electronic data transmission from the race car on track began for Audi in 1989. At that time, an Audi 90 quattro in the IMSA GTO series radioed eight parameters to the garage where engine speeds and a few pressures and temperatures were plotted on printouts – a tiny step from today's perspective, but one that provided important insights at the time. Today, an Audi R18 e-tron quattro on more than a thousand channels, in cycles that in some cases only amount to milliseconds, generates data of crucial importance to a staff of engineers at Audi Sport. At Le Mans, the engineers constantly monitor their race cars for 24 hours.

Audi SQ7 could come to US with TDI power

When Audi released the new SQ7 TDI, we couldn't help but wonder whether it would ever see an American road or showroom. And the answer is: maybe. When reached for comment on the prospect of the new diesel performance ute making its way to North America, Audi USA spokesman Mark Dahncke told Autoblog that "the SQ7 is not officially signed off on for the US, but we are optimistic." Those are encouraging words, even if they stop short of official confirmation. For those who missed the announcement in the wake of the Geneva Motor Show last week, the new Audi SQ7 TDI is a technological tour de force. It packs a 4.0-liter V8 diesel engine, augmented by two turbochargers and an electric compressor to produce 435 horsepower and 664 pound-feet of torque. It debuts a new 48-volt electrical system that powers one of the compressor and the electromechanical adaptive suspension. And just for good measure, it also features an eight-speed automatic transmission, a four-wheel steering system and all-wheel drive. The vehicle represents the first time Ingolstadt has applied the S performance badge to its largest model, and though initially announced for Europe, Dahncke's optimism leaves us hopeful in turn that it could steam its own way to American shores. If that optimism proves justified, the next big question is whether it will stick with the diesel engine or switch to a similarly powerful engine burning gasoline to more closely match American preferences – much as it did in bringing the smaller SQ5 to the US. But Dahncke tells us they "expect it to be a TDI if it does come." The decision to market a powerful diesel SUV in America would be a bold move on Audi's behalf, particularly in the wake of the diesel emissions scandal. The debacle is still fresh on the public's mind, having rocked the entire Volkswagen Group of which Audi is part – and historically a major proponent of diesel propulsion. If approved for the US market as proposed, the SQ7 TDI would far outshine the diesel versions of the Mercedes GL-Class, Porsche Cayenne, BMW X5, and Range Rover currently available – not to mention the 3.0-liter V6 TDI with 240 hp and 428 lb-ft of torque in many of Audi's models (which are, at the time of this writing, affected by a stop-sale in the US).

Delphi thrilled with results from autonomous car's cross-country trip

In the first trip across the United States ever made by an autonomous car, engineers from Delphi Automotive were surprised to learn that, in some cases, their vehicle behaved a lot like a human driver. "The car was scared of tractor trailers," said Jeff Owens, the company's chief technology officer. "The car edged to the left just a little bit when it would pass trucks, and that was an interesting observation." Engineers made hundreds of notes throughout the drive, as the autonomous car covered 3,400 miles through 15 states en route to a showcase near the New York Auto Show. Overall, company officials said the car performed better than anticipated in a variety of road and weather conditions. In the course of the cross-country drive, drivers actually controlled the car only for about 50 miles, and those cases were limited to on-and-off ramps and the occasional construction zone where lanes were not marked or only sporadically marked. The purpose of the trip was to glean information on how the autonomous car worked in a real-world environment. Google and others have tested autonomous cars and autonomous features in select real-world environments before, but Delphi's adventure was the first to trek into a test with such varied challenges over a nine-day trip that began near the Golden Gate Bridge on March 22. There are some things the engineers have already learned, like the fact the camera systems had the occasional blip when the sun-angle was low. And there are some things to still be learned, as they pour over three terrabytes worth of data from cameras, radar and lidar sensors in the weeks ahead. "It's going to take us a couple weeks to digest all this," Owens said. "But we had all the data from tests. It was time to put this on the road." Built into an Audi SQ5, the vehicle was striking, if only for the fact it looked like a normal car. Many other autonomous vehicles have quirky sensors atop the roof or other features that make them stand out as experiments. Delphi arranged this one to look as much like a normal car as possible, right down to stowing an army of computers under cargo mats, so the rear contained as much trunk space as the production model. If a fellow motorist didn't know where to look -- or take the time to notice the person in the driver's seat didn't have their hands on the wheel -- there was no reason to suspect this was anything other than a regular car.
