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 importance of Angel Eyes, Ventiports and four round taillights

Just the other day, we told you about how Lincoln isn't really a luxury brand, according to Ford's head design man, J Mays. His argument was that Lincoln lacked the unique DNA to differentiate it from the rest of the market, although the arrival of the MKZ is beginning to change that. Now, we have this video from Autoline Detroit, where Jim Hall, an analyst for 2953 Analytics who was quoted in yesterday's Lincoln story, explains the influence of certain styling cues and how they impact the brands.
Using BMW (Angel Eyes) and Buick (Ventiports) as examples for small, simple touches that serve to distinguish the brand's vehicles on the road, Hall then points out how changing trademark styling features, as Chevrolet has done on the new Corvette Stingray, can hurt the vehicle's public perception. Take a look at the full video below for an interesting dive into what these styling features mean to their individual brands.

BMW bringing special Horse Edition 7 Series to Beijing

The Beijing Motor Show is just a couple of weeks away, and BMW wouldn't miss out on the opportunity to show off its latest wares to one of its most vital markets. So when the doors open in Beijing, BMW will showcase the new 2 Series Active Tourer, 2 Series Coupe, M3 and M4, 4 Series Gran Coupe and X4. It will also introduce the i3 and i8 to China for the first time. But those are all models we've seen already. What's new is... wait for it... the 7 Series Horse Edition.
Not celebrating horses so much as the Year of the Horse, this special edition 7 Series is based on the long-wheelbase model and comes with all manner of M equipment packages, a special paint job from BMW Individual and unique touches inside and out. BMW isn't saying which engine it features, but it sells the series in China in 730Li, 740Li, 750Li, 760Li and ActiveHybrid forms, with rear- or all-wheel drive. Given that the one pictured is wearing an xDrive badge, it would have to be either the 740Li or 750Li, but buyers will presumably be able to order it in whichever spec they desire.
While it may not be as exciting as the 9 Series concept BMW is rumored to have lined up for the Beijing show as well, you can bet that the Bavarian automaker will find plenty of buyers for this extra-special, extra-Chinese, extra-equestrian luxury sedan, and command a healthy premium from each and every one of them.
