To solve diesel problem, VW might need two fixes

Volkswagen says that a fix is on the way for its 11 million vehicles around the globe that are equipped with diesel engine software that can evade emissions tests. The problem might be far more complicated than simply creating a single solution for all of them, though. According to Automotive News citing Reuters, two remedies to cover different NOx-reducing systems could be necessary, and both potentially affect performance. Earlier examples of the EA 189 diesel engine used a lean NOx trap to reduce the harmful material coming from the tailpipe. According to experts in the Automotive News report, a software update might allow the engines to achieve compliance, but that could affect fuel economy. VW already tried this route once before the scandal came to light, but tests by the California Air Resources Board still showed the figures were too high. Later, some of the 2.0 TDI engines began using Selective Catalytic Reduction that reduced NOx by injecting a urea solution into the exhaust stream. According to Automotive News, a software update for this equipment might increase the amount of the substance used. Not only would that mean topping up the fluid more often, but there still could be some reduction in fuel economy. But, since the 2-liter, 4-cylinder TDI engine that sits inside the diesel vehicles first mentioned as being affected by the issue in the US don't have a urea treatment system, VW would need to install them into these cars. VW still hasn't officially outlined its solution (or solutions) to the emissions issue but is expected to soon. The automaker's long-term evasion of regulations with these diesel engines pumped vast quantities of additional NOx into the air. The substance is known to be linked with smog and acid rain. The US Department of Justice is already beginning an investigation into the company, and politicians are pushing for harsh punishments.

Updated Audi R8 GT caught testing

When Audi introduced the refreshed 2014 R8, one of the first things we noticed was that the new R8 V10 Plus offers identical output to the outgoing R8 GT, suggesting that this limited-production model was either due to be cancelled or poised for a serious power increase. Fortunately, these spy shots have us suspecting that the latter is more likely.
Like the previous R8 GT, this new model will likely hit the gym, dropping some weight and packing more punch, but while that's all speculative, we do see that better handling is definitely in the cards. Aside from the aero-improving chin spoiler, fascia winglets and fixed rear wing, this R8 also has upgraded brakes with bigger calipers and what appear to be cross-drilled ceramic rotors. We hear output could be increased from the current 560 horsepower up closer to the 600-hp range, and laid to the pavement via Audi's Quattro all-wheel-drive system. It also very likely that Audi will keep production numbers for a 2014 R8 GT rather low, with the outgoing model limited to just 333 units globally.

2014 Audi RS5 Cabriolet [w/video]

Brash Bruiser Loses Top, Gains Weight, Still Makes Friends
Everything we said after driving the RS5 coupe still rings true, even after Audi has gone and ripped off its metal roof, replaced it with a big cloth version, and tossed us the keys. The 2014 Audi RS5 Cabriolet is another bold, big-boned airmobile to make open-top lovers swoon. There is absolutely nothing revolutionary to speak of here versus its hardtop counterpart, frankly, but tear-assing through the southern French hills as the brilliant sun warmed us is plenty good reason to talk a lot about it anyway. And hey, it beats frigid January in Detroit, where the RS5 Convertible is shortly to receive its US introduction.
One issue that could corrupt things a bit is the convertible's added weight factor. It's one thing when an Audi TT removes its top and gains 176 pounds, or when a Porsche Cayman morphs into a Boxster and gains 66 pounds; the effect on dynamics will still be acceptable. But when it comes to a huge-roof coupe like the RS5, that gain in mass becomes 400-plus pounds in cabrio form, for a grand curb weight of 4,461 pounds. As a number attached to this size of a car that's also branded with an RS badge promising raciness, we admittedly fretted. Then we drove the Audi RS5 Cabriolet to cheer up.
