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's Quandt family in hot water over Merkel campaign contributions

The mysterious and elusive Quandt family is in hot water again, nearly two years after its Nazi connections during World War II were exposed. The German family's patriarch, Herbert Quandt, nearly single-handedly saved BMW from being bought out by Daimler-Benz in 1959. Now, three living family members own nearly half of the German brand, and stand accused of buying votes with donations to the party of German Chancellor Angela Merkel, mere days ahead of a European Union vote that would cap vehicle emissions.
Merkel's conservative Christian Democratic Union accepted three donations, one from each shareholding member of the Quandt family.
Merkel's conservative Christian Democratic Union accepted three donations, one from each shareholding member of the Quandt family, totaling 690,000 euros ($935,000), on October 9. The CDU, for what it's worth, claim the donations weren't related to any political decisions and that the family have been donors for years. A Quandt family spokesperson, meanwhile, said that the family had been waiting for Germany's September 22 elections to pass before making a large contribution to the CDU.

BMW 1 Series sedan interior revealed

The next BMW 1 Series Sedan has made another appearance following our last peek at it in September, and this time, the gallery of images even reveals part of the new car's interior.
Of course, if these images prove anything, it's that manufacturers take camouflage of the interior just as seriously as they do the exterior. We can see in these images a fairly simple cabin, with what looks like a fixed central display. It's quite small, although the housing itself is rather large, so we could be looking at a more basic form of iDrive rather than the full-featured set. Overall, though, this cabin more or less confirms that the 1 Series Sedan will fit in with the rest of the BMW family quite nicely.
Outside of the interior images, though, there isn't a lot of new stuff revealed by these images. As for when we'll see both the interior and exterior fully undisguised, our spies continue pointing to a 2016 debut with a 2017 on-sale date.
