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.

2017 Audi A4 First Drive [w/video]

Internally, Audi refers to the A4 lineage with a B designation. Why the discrepancy? The model legacy traces back to the 1972 Audi 80, and the A4 name wasn't adopted until 1996 for the North American market. So the fifth-generation A4 is code-named B9. There is no confusion about what this car means to Audi. In 19 years, the brand has sold more than 12 million A4s around the world, which puts this new generation on the A-list when it comes to brand importance. If you squint, the new car looks like a facelifted version of the last-generation facelift unveiled in 2013. We get the same impression of the new A4 as we do with the third-generation Audi TT: it hasn't been comprehensively reconceived, it's been comprehensively re-detailed. But with a move to the updated VW group platform known as MLB Evo, 90 percent of the components on this car are new. On the outside, those changes are reflected through deeper sculpting on a body that's about the same height as before but 0.5-inches wider, one-inch longer, and with a wheelbase stretched 0.7 inches. The tweaked grille separates reworked Bi-Xenon headlights, which are standard across the lineup now – halogens go bye-bye. LED headlights are optional, as are the matrix units in other markets. Audi claims US-market cars will lose anywhere from 70 to 100 pounds depending on specification. Above those lights is a version of a clamshell hood – its shutline forms the front third of the pronounced shoulder line along the sedan's flanks. Audi designed a new hinge that keeps the hood lined up properly over the life of a car because small misalignments show more easily on the vertical seams. In back there are updated taillights, a standard rearview camera, and a trunk opening that's an even one meter across. In the press presentations, any conversation quickly turns to weight loss and aerodynamic efficiency. The only curb weight we have from Audi so far is for the base sedan, empty and without a driver, with the 1.4 TFSI engine that we don't get, coming in at 2,910 pounds. The current US-spec A4 is listed at 3,583 pounds, and Audi claims US-market cars will lose anywhere from 70 to 100 pounds depending on specification. About 35 pounds of that comes from the chassis, with new forged aluminum links on the suspension, fixed-caliper, four-piston brakes up front, and wheels that are never heavier than 26 pounds. The rest of the weight loss comes from the body, mostly through greater use of aluminum.

Recharge Wrap-up: BMW i3 carshare, Audi e-gas plant

Elix Wireless has announced its E10K Wireless Charging System. The system is designed for harsh conditions, delivers up to 10 kilowatts and features automatic detection and removal of foreign objects. Its low frequency makes it safe to operate near oil and gas, and in other hazardous environments. The system can charge personal vehicles, as well as electric buses, trucks, mining equipment and heavy duty machinery. Elix has "created an entirely new technology that meets customer demand for fast, safe and reliable charging," says, CEO David Smith. The E10K system uses Elix's Magneto-Dynamic Coupling technology, with rotating permanent magnets in the transmitter and receiver. Read more at Green Car Congress, or in the press release from Elix Wireless. FreeWire Technologies and Siemens are working together on a pilot program for the Mobi Charger. The mobile charging station, which uses second-life EV batteries to charge electric vehicles, will be deployed for a trial at LinkedIn's campus in Mountain View, CA. The Mobi is more flexible than stationary chargers in that it brings the charging to the car, regardless of where it is parked, rather than having to park the EV in a specific spot. It can charge up to five cars per day without putting stress on the grid during peak hours. Read more from Siemens. Audi's e-gas plant in Werlte, Germany helps stabilize the power grid. The plant, which produces synthetic methane using CO2, water and electricity, is able to draw six megawatts of power within five minutes, allowing it to become certified in the electricity balancing market. This helps the grid adapt to the larger load fluctuations that go hand-in-hand with generating renewable energy. It also allows the plant to achieve higher operating times and produce more e-gas each year. Read more in the press release from Audi. The BMW i3 is now available through the DriveNow carsharing service in Germany. DriveNow, which is a joint venture between BMW and car rental company Sixt, has put 100 i3s into service in Berlin, Hamburg and Munich. BMW also says that it supports a shift away from private car ownership in order to improve urban living and mobility, and sees electric carsharing as an important part of that. "We are witnessing the changes our customers and society as a whole are making and we are taking them on board," says BMW's Dr. Bernhard Blattel.
