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.

2014 Audi RS Q3 breaks out ahead of Geneva reveal

Ahead of its big reveal next month at the 2013 Geneva Motor Show, Audi has released a handful of images and plenty of details for the all-new RS Q3. As the first-ever crossover from the marque with RS branding, this will be the fourth RS model to go on sale this year after the RS5 Cabriolet, RS6 Avant and the RS7, and while UK and Germany sales have been confirmed, there is no word as to whether we can expect this high-performance CUV to be available in the North America.
Sharing its 2.5-liter turbocharged and direct-injected five-cylinder engine with models like the TT RS and the RS3 Sportback, the 2014 Audi RS Q3 should deliver on performance, as it pumps out 310 horsepower and 309 pound-feet of torque (peak torque starting at just 1,500 rpm and running up through 5,200 rpm). This potent engine is paired to Audi's seven-speed S tronic transmission and Quattro all-wheel drive. Despite its small stature, the RS Q3 still tips the scales at just over 3,800 pounds. Even so, performance figures are still impressive with a limited top of 155 miles per hour and a stated 0-62 mph time of 5.5 seconds. The RS Q3 also gets a sport suspension that has been lowered by 25 millimeters, launch control and weight-saving front rotors with a wave-cut and cross-drilled design gripped by massive eight-piston calipers.
Looking almost identical to what we saw last year in concept form in China, the 2014 RS Q3 looks just as sporty as its spec sheet suggests that it is. Up front, the fascia gets massive air intakes with silver vertical accents and, like other recent RS models, the Quattro emblem is written across the lower air intake. The silver accent motif also continues on the grille surround, mirror caps, roof rails and rear diffuser trim, and the oval exhaust outlet is also an identifying feature of Audi's RS cars.

Audi considering other variants, turbo V6 for R8

More details from the Audi R8 event at Spain's Ascari circuit have met the Internet, and they provide more intel on the supercoupe will evolve over the second generation. First, they note some small differences in stance with this new car, being wider than the current car and sitting 30 millimeters (1.18 inches) lower. Compared to its Lamborghini Huracan brother, it gets three extra centimeters in the wheelbase. Filling out the power numbers, the 'entry-level' V10 engine at launch rolls out 540 horsepower and 399 pound-feet of torque, does the 0-60 mile per hour dash in 3.5 seconds, and hits a top speed of 200 mph. The V10 Plus model rocks 620 hp and 412 lb-ft, which slices 0.3 seconds off that acceleration time and adds five more mph to the top speed. They'll transfer their power through a seven-speed S-tronic that shifts faster than before, and it will in turn send power through an electronically-controlled clutch at the front axle and a constantly variable limited-slip differential at the rear axle. The power split is said to default to 42/58 front-to-rear, but 100 percent of the torque can be sent fore or aft. Benchmarked against the 991-series Porsche 911, driving sensations travel through an electromechanical steering setup that can be had with a variable rack if preferred, leading to standard 19-inch wheels with the option of 20-inchers and tires developed specifically for this car. A Performance setting offers dry, wet, and snow modes; that first setting turns the ESC off except for situations of impending doom, and Audi racer and test driver Frank Stippler told Top Gear that understeer is reduced, to which TG added "it oversteers at will." Stippler said it's "a lot closer to the GT3 race car than ever before," and even though it's "a lot" less intense than the Huracan, it's just as fast on the track. His estimate is that the new R8 will lap the Nurburgring between ten and 15 seconds faster than the current car. R8 technical lead Roland Schala said the new chassis opens up new avenues of development because "there's no problem to change it," mentioning models like a Clubsport or Superleggera as no longer forbidden. Differentiation could come from a wider engine mix, too. Markets like China need smaller displacements, so Audi's twin-turbo V8 is expected to join the line-up at some point, bringing 500 horsepower.
