Audi spotted testing new S4 at the Nurburgring

Where there's smoke, there's fire. Only in this case, the smoke is the upcoming new Audi A4, and the fire is the S4 spotted undergoing testing in this latest batch of spy shots. Snapped in both sedan and Avant wagon forms while undergoing testing on and around the Nurburgring – where else? – the next-generation Audi S4 will of course be based on the new A4 that's anticipated to debut in Frankfurt this September. That means MLB Evo architecture and styling that takes a page out of the new TT's playbook. But in S4 trim, it'll be altogether more performance oriented. Expect an even more powerful version of the outgoing model's 3.0-liter supercharged V6, pumping out a good 340-350 horsepower to all four of its driven wheels. That power will help it keep pace with the new Mercedes C450 AMG Sport. It won't have to take on the new C63 AMG directly, though, as that'll be the job of the next RS4 that will slot above it. But since that model may never make it to US showrooms, this will stand as the flagship of the new A4 family as far as the American market is concerned. Related Video:

Audi wants to keep you healthy while behind the wheel

Health tracking is all the rage. You can get smart watches and smart wristbands and all sorts of silly tech to give you intricate metrics about your wellbeing. Hell, my bathroom scale is connected and will automagically sync my latest weight, body fat, and heart rate readings to an app on my smartphone. Bathroom scales and wearables aside, Audi is hoping to bring this fitness-tracking tech to four wheels with its new Fit Driver system. No surprise, the new program was announced at the technophile's paradise that is the Consumer Electronics Show. Paired with a wearable, like an Apple Watch or FitBit, that would monitor heart rate and skin temperature, the car's sensors can track a driver's breathing and driving style. This data can be analyzed alongside weather and traffic information, effectively allowing the car to determine how stressed or tired a driver is. Systems within the vehicle would then be tweaked to "relax, vitalize, or even protect the driver." This can take the form of an automatic massage and adjustments to the cabin temperature, ambient lighting, and infotainment. So when you're about to go full road rage because there's a Camry doing ten under in the left lane, Sirius could flip on the easy listening of Watercolors to calm you down. Naturally, this technology is still in the early stages, and there's no word about when it could actually arrive in production vehicles. But as driverless systems evolve, Audi is aiming to develop such an advanced health suite that an autonomous vehicle could detect a medical emergency, pull over safely, and call for assistance. Here's to the future, folks. Check out the official release below. Audi Fit Driver Audi envisions a future in which drivers leave their cars more relaxed than when they entered them. The car, as a personal yet simultaneously connected space, is ideal for health and fitness monitoring. Under the motto "my Audi cares for me", Audi Fit Driver will become a supportive driving companio. The Audi Fit Driver project focuses on the well-being and health of the driver. A wearable (fitness wristband or smartwatch) monitors important vital parameters such as heart rate and skin temperature. Vehicle sensors supplement this data with information on driving style, breathing rate and relevant environmental data such as weather or traffic conditions. The current state of the driver, such as elevated stress or fatigue, is deduced from the collected data.

2015 Audi TT's digital gauge cluster to spread throughout lineup

File this one under: "makes sense to us." According to Car and Driver, the slick new gauge cluster found in the 2015 Audi TT will expand to other models in the automaker's lineup. In the near term, expect the tech to make its way into the next R8 supercar (with a special performance display for that model), as well as the upcoming, all-new versions of the A4 sedan and Q7 crossover.
Audi's new customizable gauges first debuted at this year's CES - it uses a 12.3-inch TFT display, and, while similar to the systems found in the Cadillac CTS, XTS and Mercedes-Benz S-Class, this system has the ability to show full-screen, three-dimensional maps. We had a chance to check out the new display in-person at CES, and found it to be impressive, though we're curious to see how distracting it is while driving.
Car and Driver says the system is still undergoing small tweaks before Audi officially launches it in the TT later this year. From there, the display will be standard in the R8, but Audi is unsure about whether or not to offer it as a standalone option in the higher-volume A4 and Q7 models.
