VW fix would have cost $335 per vehicle

Since the Volkswagen diesel kerfuffle began, Bosch, the world's largest auto supplier, has been hooked up to a bullhorn trying to make sure everyone knows its side of the story. Bosch supplied VW with the engine management testing software, including delivery and metering modules, that VW then used to skirt emissions laws in the US. Bosch told VW in 2007 that it was illegal to use the software in cars it planned to sell yet VW did it anyway, according to reports coming out in German newspapers Bild am Sonntag and Frankfurter Allgemeine Zeitung. That first warning came two years after VW started developing the small-displacement diesel, around the time that the two men pushing its development, then-brand chief Wolfgang Bernhard and engineer Rudolf Krebs, were telling their superiors that the engine needed AdBlue urea injection to pass US emissions. VW cost controllers wouldn't approve the AdBlue solution because it would add 300 euros ($335 US) to the cost of the vehicle. Bernhard and Krebs left the same year that Bosch advised VW about the software, two years before the engine went into production. That's when things get cloudy. A report in Automotive News says that when Martin Winterkorn took over in 2007 as head of the VW Group and brand, he asked Ulrich Hackenberg and Wolfgang Hatz to keep working on the engine, and "[the] engine then ended up in VW Group diesels" with that problematic software still intact. No one has yet pointed any fingers at this latter chain of command, but like a game of Clue, right now they're the professors in the library holding the candlesticks. Warnings didn't only come from the supplier: Frankfurter says VW's initial investigation has found that an engineer issued the same caution to the company in 2011. Neither Bosch nor VW would comment on the reports.

For Audi, Quattro name means something for hydrogen cars, too

Forget Dueling Banjos. Audi is proposing "Dueling Motors" for its Audi A7 Sportback H-Tron Quattro concept vehicle. All in the name of appropriate pickup, of course. The German automaker, which showed off the concept sedan at the Los Angeles Auto Show last month, is pairing a plug-in electric motor with a hydrogen fuel cell powertrain. Each motor powers two wheels, maintaining the Quattro's all-wheel-drive pedigree. The car's 8.8-kWh lithium-ion battery can drive the car as far as 31 miles on battery-power alone. After that, the water-vapor-spewing fuel-cell engine kicks in. Audi executive Ulrich Hackenberg told Automotive News Europe that the unusual set-up is necessary because the hydrogen fuel cell powertrain alone would only power two wheels while providing an insufficient 136 horsepower. Not exactly sport-sedan material, especially for a car that weighs about 4,300 pounds, even if it is a zero-emission ride. Combined, the two engines give the sedan 231 horsepower as well as a combined single-charge/full-tank range of almost 350 miles. What it all means is that the A7 can go from 0 to 60 miles per hour in less than eight seconds and has a top speed of about 112 miles per hour, and can still dash through the snow.

Is this the Audi C-BEV Concept?

The head of R&D at Audi, Ulrich Hackenberg, used part of his comments at the company's annual conference to broach the subject of an all-electric SUV. He didn't give many details, but he said it would be based on the same MLB 2 platform as the Q7, would have a range of more than 311 miles, and perhaps use a battery rated at 90 kWh. German publication Auto Motor und Sport has just published sketches of what that SUV, supposedly codenamed C-BEV internally, will look like when we see it in concept form at the Frankfurt Motor Show. Autocar's sources say this is a five-seat, "production-relevant zero-emissions concept" that offers hints about the coming Q6 and how Audi plans to battle the BMW X6 and Tesla Model X. Autocar says the lithium-ion battery, placed inside the platform, could hit that 90 kWh number, and power three electric motors. One of the motors is mounted in the transmission, two more at the rear axle, and combined output is reportedly 500 horsepower and 516 pound-feet of torque. Styling will aim for something coupe-ish, the company expecting it to be so sleek that it will have a coefficient of drag under .30. For comparison, the Audi A6 has a Cd of .28. All-out luxury is the word here, with interior architecture shared with the next A8, and "Range Rover rivaling ride quality." We're not sure if this has anything to do with Audi's announcement that it will show a concept with OLED matrix lighting at Frankfurt, but the production vehicle that the Frankfurt concept leads to will go on sale in late 2018.
