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.

Watch a trio of Santas ride up Mulholland Drive

Santa Claus might have his eight reindeer - or nine, when it's foggy - to help him deliver presents in most parts of the world, but in southern California, it looks like he's traded up from Dasher, Dancer, Prancer and company to BMW, Yamaha and Ducati. RNickeyMouse is usually the place to check out spectacular motorcycle crashes on video along LA's Mulholland Drive, but a recent video caught a trio of Santas carving up the iconic, twisty road.
The three Santas are together, riding what appears to be a BMW S1000RR, Yamaha R1 and a hard-to-tell custom bike that could be a Ducati 1098. The video, which is posted below, also catches a bonus Santa riding solo on another S1000RR. Happy Christmas to all, and to all a cool bike!

BMW 2 Series Active Tourer corners surprisingly flat on 'Ring

With seven seats and front-wheel drive, you might not expect the upcoming long-wheelbase version of the BMW 2 Series Active Tourer to live up to the Ultimate Driving Machine reputation that BMW has fostered over the years. But the latest spy clip from the Nürburgring suggests otherwise.
The Bavarian automaker has apparently been testing its new people mover on the Nordschleife, getting it ready to join the growing 2 Series family. And though it's wearing heavy camouflage, we can clearly see from the video below that it's cornering impressively flat - which bodes well for those who'll need to transport their expanding family but aren't prepared to give up on handling.
