Audi celebrates 25 years of TDI

Nope, the diesel engine never really did go out of style for Audi. Now, the German automaker has released a video reminding the world of its persistence with the oil-burners and is commemorating the Silver Anniversary of Audi's first commitment to turbodiesels in 1989. And, yes, there are some road racers shown in the clip, so some of those bad boys actually move pretty well. Audi engineers on camera admitted to some of the early TDI engines being "slow" but still valuable for their torque and, obviously, their fuel economy relative to gas-powered engines. A bunch of tinkering later, though, and Audi says its diesels can be a legitimate "part of a performance car" and has even overcome the issue of noisiness that's often associated with diesels. The automaker made some news in these parts a few years back when its Audi A3 TDI won the 2010 Green Car of the Year at the annual LA Auto Show in late 2009, and the model even succeeded a fellow diesel (the Volkswagen Jetta TDI) to boot. Granted, diesel sales aren't nearly as popular in the US as they are in Europe. Still, Audi last year boosted its diesel sales in the US by 40 percent to 10,076, which was about a tenth of what sister company Volkswagen sold in diesels last year in the States. And things have looked even rosier this year for Audi's TDI sales. Through June, Audi diesel sales have almost quadrupled from a year earlier to more than 8,100 units. Check out the 150-second video on Audi's 25-years of TDI production below.

Delphi plans automated-driving journey across the United States

Delphi is attempting to become the first company to pilot an automated car across the United States. The global automotive supplier will start a cross-country journey from a location near the Golden Gate Bridge in San Francisco starting on Sunday, March 22, and cover approximately 3,500 miles on a trip to New York, where it will arrive sometime during the New York Auto Show. Along the way, Delphi engineers will gather data on how the car, an Audi SQ5, performs in a variety of road and weather conditions that the company says could only be tested in a real-world environment. "Delphi had great success testing its car in California and on the streets of Las Vegas," said Jeff Owens, the company's chief technology officer. "Now it's time to put our vehicle to the ultimate test by broadening the range of driving conditions." A formal announcement is expected tomorrow during the SXSW festival in Austin, TX. The company recently demonstrated many of its advanced-safety and automated driving technologies during CES, driving in Las Vegas. The cross-country trip will include tests on its radar, vision and advanced-drive assistance systems, certain vehicle-to-vehicle and vehicle-to-infrastructure communications, and intelligent software, which includes automated highway pilot with lane-change technology, automated urban pilot and automated parking functions. Though a driver will be behind the wheel throughout the journey, Delphi says its active safety technologies can make complex decisions, like stopping and proceeding at four-way stops, timing highway merges and calculating safe maneuvers around bicyclists. While California has certain motor-vehicle laws that help regulate autonomous vehicles, it was unclear whether Delphi needs special arrangements or permission from other states to conduct automated-vehicle testing elsewhere – or if those concerns might be negated by an active driver. Earlier this year, Audi turned heads at CES by driving an A7 from San Francisco to Las Vegas in a similar display of automated-driving technology.

With increased range, Audi R8 E-Tron revving up for production. Maybe

As Tesla Motors proved mightily in 2013, an expensive EV with a long range can sell quite nicely, thank you very much. Perhaps Audi was taking notes, since its all-electric R8 E-Tron's on-again/off-again odyssey appears to be on again, according to UK's Autocar, citing Audi's Urlich Hackenburg. The model is near the approval stage for production, and the key to the green-light is the fact that its single-charge range has been almost doubled to 250 miles. The R8 E-Tron gained kudos in these parts last June by turning in a rather brisk 8:09 time around Germany's Nurburgring track, a record for a production electric vehicle (check out the really quiet video here). Still, plans for the 376-horsepower model, which has two electric motors and was first shown off at the Frankfurt Auto Show in 2009, had been put on the proverbial blocks largely because of a relatively short single-charge range of about 150 miles. Then word came out last spring that Audi would produce maybe 10 units before reports from Australia's Drive late last year indicated that plans for potentially broader production were being resuscitated.
