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.

Next Audi A8 to drive itself up to 37 mph

Audi has been publicly, loudly, working the autonomous angle for years - it was working on Shelley, the autonomous TTS that would climb Pikes Peak in 27 minutes, way back in in 2009. Parent company Volkswagen had been working with Stanford University on autonomous vehicles for five years before that, and the same program collaboration would take the lead in Audi's efforts here. Where are we now? Well, a convoy of Audi A7s just drove journalists from San Francisco to the Consumer Electronics Show in Las Vegas, with "piloted driving in 100 mile stints." On the highway, the "piloted driving" A7 works up to 70 miles per hour and can change lanes, pass other cars, accelerate and brake on its own. A report in Autoweek says public adoption of the technology will continue with the next-generation A8, which will be able to navigate on its own up to 37 mph, make its way through traffic, find a parking spot and park itself. Over time, capabilities will be added - like a higher mph limit - as the technology and the legal issues are fine tuned. The A7 that just did the SF-to-LV run doesn't work in cities, only on highways, so it appears Audi is kicking this off with the abilities demonstrated in an A6 Avant last year at CES. That car had a Traffic Jam mode that only worked in dense traffic and up to 40 mph, but when in operation, it allowed the driver to watch a movie or conduct a videoconference. We have a feeling those two bits of icing won't be included in the fourth-generation A8, though. We'll be late to the party when the big sedan comes; Audi says it will go on sale by the end of 2016, but the US isn't expected to get it until 2017 as a 2018 model.

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.
