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.

BMW expects China to pass US as its top market in 2013

When you combine two billion citizens, 100 cities with more than a million inhabitants and an economy that's as unrestrained as Jim Cramer on an Adderall binge, China's explosive auto industry growth shouldn't be a huge surprise. Audi already lists the communist country as its largest market, while Mercedes-Benz is expecting it to be there in the next few years. Now, according to a report from Automotive News, BMW is expecting the People's Republic to overtake the United States in sales by the end of 2013.
We already discovered the extent that BMW is going to in establishing a dedicated Chinese stronghold, when we explored BMW's Shanghai-based DesignWorks studio ahead of April's Shanghai Motor Show. And while we argued that DesignWorks Shanghai hasn't really borne fruit, it isn't due to a lack of sales.
BMW China has seen a 16-percent jump in year-over-year sales, lead by a 28-percent gain in 5 Series sales. Part of BMW's growth strategy comes from an ever-expanding dealership network. Remember those 100 cities we mentioned with over one million people? According to Karsten Engel, CEO of BMW's Chinese operations, those 100-million-plus city dwellers don't have access to a premium dealership.

Jalopnik and Consumer Reports see who can pull off the best snow drift

The weather throughout much of the United States is pretty awful at the moment with some combination of extremely low temperatures, inches of snow and maybe some ice underneath it all. The folks at Jalopnik and Consumer Reports are making the absolute best out of a difficult situation by heading to CR's snow-covered test track and attempting to make the longest drift in a quartet of very different performance vehicles. Jalopnik brought along a Mercedes-Benz E63 AMG S Wagon, a Subaru WRX STI, a BMW 228i and a 1973 Volkswagen Baja Bug (heck yeah!) for the challenge. Also, the track was perfect for this group, with a mix of packed snow in places and still a few inches of unsullied powder in spots too. Ostensibly the goal was to get the tail to step out through a particular corner, but in reality this was more about having hilarious fun in the snow with fast cars. The result just looks like the best time humanly possible in this weather.
