Race Recap: 2013 Twelve Hours of Sebring, cakewalk up front, grindfest out back [w/spoilers]

This year's 12 Hours of Sebring wasn't exactly a foregone conclusion because we're still talking about racing, and anything can happen when the speeds are as high as the adrenaline and the desire. But we're still talking about Audi bringing it's two top-spec racers - and its huge budget and its nearly neurotic attention to detail - to a race that it uses as a test bed for The 24 Hours of Le Mans and as a way to open the endurance racing season with a victory.
Besides, 12 hours is a long time, especially at Sebring, and things didn't go all Audi's way. On top of that, although it was a pretty quiet race, behind the Audis things got even grimier, with plenty of battles, plenty of mechanical issues, and the new BMW Z4 GTE and Viper GTS-R being race tested. Oh, and that brand new chromed-out DeltaWing...

The next-generation wearable will be your car

This year's CES has had a heavy emphasis on the class of device known as the "wearable" – think about the Apple Watch, or Fitbit, if that's helpful. These devices usually piggyback off of a smartphone's hardware or some other data connection and utilize various onboard sensors and feedback devices to interact with the wearer. In the case of the Fitbit, it's health tracking through sensors that monitor your pulse and movement; for the Apple Watch and similar devices, it's all that and some more. Manufacturers seem to be developing a consensus that vehicles should be taking on some of a wearable's functionality. As evidenced by Volvo's newly announced tie-up with the Microsoft Band 2 fitness tracking wearable, car manufacturers are starting to explore how wearable devices will help drivers. The On Call app brings voice commands, spoken into the Band 2, into the mix. It'll allow you to pass an address from your smartphone's agenda right to your Volvo's nav system, or to preheat your car. Eventually, Volvo would like your car to learn things about your routines, and communicate back to you – or even, improvise to help you wake up earlier to avoid that traffic that might make you late. Do you need to buy a device, like the $249 Band 2, and always wear it to have these sorts of interactions with your car? Despite the emphasis on wearables, CES 2016 has also given us a glimmer of a vehicle future that cuts out the wearable middleman entirely. Take Audi's new Fit Driver project. The goal is to reduce driver stress levels, prevent driver fatigue, and provide a relaxing interior environment by adjusting cabin elements like seat massage, climate control, and even the interior lighting. While it focuses on a wearable device to monitor heart rate and skin temperature, the Audi itself will use on-board sensors to examine driving style and breathing rate as well as external conditions – the weather, traffic, that sort of thing. Could the seats measure skin temperature? Could the seatbelt measure heart rate? Seems like Audi might not need the wearable at all – the car's already doing most of the work. Whether there's a device on a driver's wrist or not, manufacturers seem to be developing a consensus that vehicles should be taking on some of a wearable's functionality.

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.
