California orders VW Group to fix 15,000 3.0L diesel vehicles

The California Air Resources Board has ordered Volkswagen to come up with a plan for repairing approximately 15,000 cars sold in the state that contain illegal software that may circumvent emissions testing. In a letter sent to Volkswagen Group of America and several company brands, CARB's chief emissions officer says the company has 45 business days to submit a recall plan that will fix affected Volkswagen, Audi, and Porsche models equipped with 3.0-liter diesel engines sold in the state since 2009. "We expect full cooperation in this investigation so this issue can be addressed expeditiously and appropriately," wrote Annette Herbert, chief of emissions compliance. The violations first surfaced in a meeting last week between California regulatory officials and Audi executives. In that meeting, Audi admitted certain versions of A6, A7, A8, Q5 and Q7 models contained three previously undisclosed auxiliary emissions control devices. An auxiliary device is not necessarily the same as a defeat device that intentionally cheats on emissions testing, but Audi and other affected brands hadn't disclosed the existence of the AECDs, which is a violation of the state's health and safety code. Had they been disclosed prior to vehicle certification, there's a possibility CARB may have approved use of the devices. In a statement Wednesday, CARB did not elaborate on whether it considered the three devices mere AECDs or defeat devices. When Volkswagen submits its plan to fix the cars, CARB says it must include an assessment of how the repairs will affect fuel economy, performance, drivability, and the safety of each vehicle. The 15,000 cars affected in California are part of roughly 85,000 nationwide which contain the affected 3.0-liter engines. The US Environmental Protection Agency may soon address how it expects Volkswagen to fix the remaining cars. "EPA and CARB are working closely and continue to investigate following the admission by Volkswagen that the issues EPA identified in the November 2nd NOV (Notice of Violations) extend to all 3.0-liter diesel Volkswagen, Audi, and Porsche vehicles," an agency spokesperson said in a statement Wednesday. "EPA will take all appropriate enforcement action." The 3.0-liter developments, of course, come on top of the company's September admission that 482,000 diesels equipped with 2.0-liter engines contain defeat devices that detect emissions testing and alter the cars' performance.

Electric turbos promise big performance and efficiency gains in the near future

An electric turbo system boosts efficiency between 15 and 20 percent, according to Audi.
Turbochargers, like acoustic guitars, use moving air to create magic. And electric turbochargers, like electric guitars, provide the ability to amp up that magic to amazing new levels.

Audi's diesel-electric supercar is codenamed 'Scorpion'

Speculation continues as to the final nature of the diesel-hybrid Audi supercar said to arrive in 2016 or 2017. A previous report in Automobile had the halo coupe, based closely on the R18 etron quattro endurance racer, codenamed R20 and pegged to look like a Le Mans winner for the street with around 700 horsepower and 737 pound-feet of torque from a twin-turbo V6. Now Car and Driver has updated the gossip with a report that the car is internally called "Scorpion," and it will be even closer to the R18 than supposed.
CD says the heart of the car will use the R18 etron quattro's carbon fiber tub and its engine will be "taken directly" from the race car. That means a 3.7-liter V6 with a single turbo that, in ACO-spec restricted form, outputs 500 hp and 625 lb-ft - CD suspects production output could get to 600 hp - and drives the rear wheels, aided by hybrid motors driving the front wheels. And remember, at Le Mans the R18's hybrid motors can't kick in until they're above a certain speed in order to prevent Audi from getting an advantage coming out of slow corners. A street car wouldn't face that restriction.
The Scorpion would be a fulsome and undiluted example of the technologies Audi has created during its return to sports car racing. Its exterior design hasn't been finalized, with CD citing either the convoluted concept of "a retro take on the future of racing" or packaging that would adhere to the R18's looks. To make sure it is properly appreciated and sells well, production could be limited to the same 333 units as the R8 GT and A1 Quattro.
