2013 Dinan S3 BMW 550i

Steve Dinan has been enhancing BMW models since 1979. But don't throw his company into the ring with the dozen or so other tuners who tweak, tinker and piggyback upgrades on the famed German marque. Dinan is a tuner, but it's also an engineering firm that writes its own software, builds its own parts and then backs everything it does with a factory-grade warranty. That sort of fastidiousness comes at a price, but most of its customers - including the powerhouse of BMW Motorsport - rely on Dinan to help them come out on top.
In stock form, BMW's 550i is a formidable four-door with a twin-turbocharged 4.4-liter V8 rated at 400 horsepower and 450 pound-feet of torque. While those figures allow it to run with quick company (0-60 in 5.0 seconds, according to the automaker), Dinan puts the sedan's kettle on full boil with its S3 package. Starting with the engine, the performance engineering firm bolts on larger turbochargers, air-to-water intercoolers, a trick strut tower brace cold air intake, a quad-pipe free flow exhaust and its own engine management software. Pump in some premium fuel, and the result is 542 horsepower and 587 pound-feet of torque. Power is sent through the stock eight-speed automatic to a limited slip rear differential (Dinan will upgrade xDrive all-wheel drive models, too).
The Dinan S3 also features and extensive suspension upgrade that includes new front camber arms and low compliance rear control arms (engineered to reduce understeer and improve turn-in). The stock dampers are retained, but new bump stops are installed along with new springs. Overall, the car rides about a half-inch lower than stock to improve roll rate. To reduce unsprung weight, forged 20-inch HRE Performance wheels are fitted at all four corners (wearing Michelin Pilot Super Sport tires - 275/35ZR20 up front and 295/35ZR20 in the rear). Lastly, the company remaps the factory Electronic Damper Control (EDC) software with its own Dinan Shockware to work in conjunction with the new enhancements.

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.

Ferrari, BMW lend expertise to Olympic bobsled, skeleton, luge

LONDON — There are plenty of reasons why the sport of bobsleigh is sometimes referred to as Formula One on ice, but few as obvious as Italy's World Cup sleds. Resplendent in Ferrari red, and with a set of team sponsor Pirelli's P-Zero tyres painted on the sides, they are even liveried to look like racing cars. Ferrari, Formula One's most glamorous and successful team, have worked with the Italian federation, whose sleds run without sponsor branding at the Olympics, since 2010 and in the run-up to next month's Pyeongchang Winter Games. Former rival BMW, title sponsor of the World Cup, has long partnered the U.S. bobsleigh team, while McLaren teamed up with Britain's bob and skeleton athletes for the 2014 Sochi Games in Russia. "There's always the link between the Formula One companies, or any motor company, and skeleton and bobsleigh," says Rachel Blackburn, the engineer who has been involved in Britain's skeleton program since 2006 and who used to work for McLaren. "There's the Ferrari sleds and the BMW sleds ... when we were at McLaren it kind of made a good story," she told Reuters by telephone from her home in Dubai. That somewhat manufactured rivalry has died down in the years since Sochi, with McLaren no longer involved and Ferrari's presence low key. But the worlds of grand prix motor racing and sliding sports still have plenty in common. Bobsled, luge and skeleton are among the fastest of Olympic sports, with bobsleds reaching speeds over 90 mph. Drivers are subjected to gut-wrenching G-forces, and crashes can be fatal. And then there is the ongoing debate about cost controls, the direction of future rules, preserving a level playing field and obsessive secrecy — all endlessly recurring themes in Formula One. 80 mph on a tea tray Blackburn said skeleton, where riders hit 80 mph on what has glibly been compared to an oversized tea-tray, sits somewhere between Americas Cup yachts and Formula One cars in terms of speed and aerodynamics. "Applied engineering is far more interesting than the pure stuff, so when its applied to something that's fun and exciting it does make it a lot easier to solve problems," she said. "There is the Americas Cup, sailing, Formula One and the high speed ice sports as well. It's the same concept.
