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 Q7 to debut with electric turbocharger?

For years, the concept of an electric turbocharger was essentially a joke sold on eBay to boost power in your slammed Civic, but in the last five years it has moved from an idea on a piece of paper to a feasible reality. Audi has already toyed with a showcase of the cutting-edge tech in road cars with the RS5 TDI concept. Now, reports suggest an electric turbo may make it to the streets as soon as next year in the next-gen Q7 (spy shot pictured above).
"I can confirm we are working on the development of the e-boost definitely," said Ulrich Weiss, Audi's diesel engine boss, to Australia-based Drive. He didn't give an exact timeframe but hinted at sometime next year, possibly in the Q7. He also suggested the chance of an RS-branded diesel model in the vein of the RS5 TDI concept on the horizon, as well.
This tech isn't entirely new for the folks in Ingolstadt. Audi's R18 endurance racer already uses such a system to capture waste heat from the engine, converting it to electric power to further power the hybrid car. The RS5 TDI concept employs a similar idea with a 3.0-liter, twin-turbocharged V6 with an electric supercharger to make up for the turbo lag. It's able to pump out 385 horsepower and 553 pound-feet of torque and allegedly sprint to 62 miles per hour in four seconds.

Audi reveals R8 E-Tron Piloted Driving concept at CES Asia

Designed as they are to take the driver out of the equation, you might think that the idea of an autonomous vehicle would seem diametrically opposed to that of a supercar. But Audi disagrees. The German automaker has cooked up a series of "piloted driving" concepts that are increasingly focused on performance, and this could be the ultimate iteration yet. Audi's latest Piloted Driving demonstrator is based on the R8 E-Tron. It's altogether almost identical to the one we saw in Geneva, packing an electric powertrain to deliver 456 horsepower, 679 pound-feet of torque and a 0-62 time of 3.9 seconds. Only in this case, it can do it all on its own, without any driver intervention. To pull that off, Ingolstadt has fitted this show car with an array of sensors, including a new laser scanner, multiple video cameras, ultrasonic sensors and radar transmitters at both ends – all handled by a central "driver assistance control unit." It's the latest in a series of concept cars that has already included a version of the RS7 Sportback designed to lap the racetrack, and the Prologue concept that drove itself to CES. This concept was similarly unveiled at CES Asia, the Eastern counterpart to the tech expo we usually catch in Las Vegas. Just what the point is in engineering (or buying) one of the best-driving cars on the market and then handing over its operation to a computer, we don't quite get. But at least we can rest easy knowing that Audi is not giving up on performance as autonomous tech turns the driver into just another passenger.

The technology study is one of the highlights of CES Asia, and it brings together future technologies – which relate to lightweight design, high-performance drive systems and functions for piloted driving. The Audi R8 e-tron piloted driving concept car is based on the multimaterial Space Frame of the new production R8. A rear car body module made of carbon fiber reinforced polymer (CFRP) integrates the luggage compartment, which extends the frame structure. The walls of the luggage compartment shell are corrugated, so that they can absorb extreme amounts of energy with little material weight in case of a rear-end collision.
