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 starts Apple-like "Genius" program to explain tech

Even workaday cars are so capable now that even most auto scribes don't truly find out about a car's limits until a professional driver shows them what they are. It's the same with a vehicle's suite of features and the technology inside - there's so much of it that most people will have no idea what their cars can offer them. BMW is the latest company to make a personal effort to change that, introducing "young, tech-savvy employees" to dealerships as part of its "BMW Genius Everywhere" initiative.
Having no part in the actual sale of a vehicle, a BMW Genius is present on the showroom floor only to answer questions about the company's products and their features. If the customer decides to buy, he is transferred to a salesperson. A pilot program in the UK proved its effectiveness, it will now be rolled out across Europe and then come to the United States toward the end of this year in time for the launch of the i3. Details are still being worked out, but each BMW dealer will have at least one Genius.
For assistance that doesn't require visiting the auto mall, BMW is also putting vehicle and feature tutorials on its US website to "make our knowledge about our brand more interesting and more accessible to the consumer." They will appear online sometime in the latter half of the year, and will also be bundled into iPhone and iPad apps.

M-fographic breaks down the history of BMW performance machinery

Few characters carry the kind of clout among performance enthusiasts as the letter M. For 35 years now, that one letter has adorned over 300,000 BMWs, each tuned to deliver a higher degree of performance than the stock models on which they're based.
The M division has worked up nearly 100 different models over the past third of a century, which can leave even the most expert among Bimmer fanatics bewildered. Fortunately British auto loan service Carfinance247 has commissioned this handy infographic to make sense of it all, and you can check it out below to see what the letter M really stands for.
