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 8 Series turns 25 [w/video]

From the very beginning, the BMW 8 Series was a head turner. It was hardly a common sight in the first place, and the angular lines and low, pointed nose made the GT look like something special on the road. It's been 25 years since the Bavarian brand's flagship coupe of the '90s debuted, and owners celebrated the anniversary in style in Germany.
The 8 Series still looks great today, but its popup headlights give away its age a little. You just don't see them anymore. It was introduced at the 1989 Frankfurt Motor Show as the 850i with a 5.0-liter V12 under the hood capable of 295 horsepower and 332 pound-feet of torque. Later, even bigger V12s would find their way in there. Production lasted until 1999, but they were rather exclusive with 30,621 built in its lifetime.
To celebrate the anniversary, several BMW clubs organized 120 examples for display at the company's headquarters in Munich. The brand took advantage of the display to show off the ultimate 8 prototype as well. The one-off special packed a 550-horsepower V12 and a body with optimized aero. That engine eventually became the basis for the one in the McLaren F1.

BMW X4 tunes up its crossover game in Germany

Except for the fancy wheels and the overly expressive fascias, the production version of the BMW X4 looks like it will carry over practically untouched from what we saw in the X4 Concept several months back. With the same fastback roofline as the concept, these spy shots show that the X4 is taking shape to be a baby version of the BMW X6.
Sharing the same platform as the X3, the lower and wider X4 will be positioned slightly more upmarket - as is the case with the X5 and X6. We hear that this could mean that the X4 will ditch the X3's base engine to give an even sportier feel right out of the gate, but word has it that an M version will being showing up down the road as well.
BMW has already revealed what it plans to show off at the Frankfurt Motor Show (i3, 4 Series Coupe, next-gen X5, refreshed 5 Series, X5 Concept eDrive plug-in hybrid and Concept Active Tourer Outdoor), so barring any surprised we definitely won't be seeing the X4 there. At this point, with as close to production as these images would have us believe, our best guess would be that we'll see the X4's official unveiling happen either at LA or Detroit.
