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 brings burlesque, Warhol, M1 and 6 Series Grand Coupe to Paris Photo LA

BMW has worked with Paris Photo for ten years. This year, the photography exposition lands in Paramount Studios in Los Angeles for the first time, and BMW is not only coming with it, the Bavarians are bringing the Art Car that started it all: the 1979 M1 painted by Andy Warhol. For those attending the show, there will also be making-of video of Warhol working on the car - but if you remember the mini lecture that EVO magazine's Henry Catchpole gave on the Art Cars, you'll remember that Warhol finished the car so quickly that the cameraman barely had time to get the film rolling.
With that will also be a series of photos of the BMW 6 Series Gran Coupe dropped into noir scenes accompanied by burlesque models, all taken by photographer Uwe Düttmann. It's the first time they'll be exhibited at Paris Photo. You can check out a few of them in the high-res gallery above, and there's a press release below with more info.

Alpina B3 Bi-Turbo burns all the midnight oil

We've got good news and bad news for you, boys and girls, from the floor of the Frankfurt Motor Show. The good news is that the BMW M3 has come early, with a diesel, in wagon form - albeit with a different name. The bad news is that it will in all likelihood never make it to America. Which is a shame, because it's awesome.
What we're talking about, of course, is the new Alpina D3 Bi-Turbo. BMW's wickedly talented but lesser know stepchild has created a 3 Series with a 3.0-liter twin-turbo diesel six packing 345 horsepower and 516 pound-feet of torque. You - and by "you," we mean overseas buyers - can choose between sedan or wagon, as well as rear- or all-wheel drive. But the bottom line is a 4.6-second 0-62 time and a 173-mph top speed... from a diesel.
We scoped out the rear-drive wagon Alpina brought to the show, decked out in its signature blue. And you can, too, in the gallery of live shots above, along with the freshly assembled stock photos of both sedan and wagon versions in the gallery below.
