BMW preparing new M4 GTS with water injection

Last month, BMW revealed a new safety car for the MotoGP series. Only instead of just taking one of its production models and giving it some flashing lights, special livery and emergency equipment, the Bavarian automaker used the specially equipped M4 to showcase a new water injection system. And now word has it that the tech is being worked into a new M4 GTS. The system sprays water into the combustion chamber in order to lower the temperature of the air and increase the engine's efficiency, thus allowing it to produce more power without overheating, and relying less on ambient temperatures. It does require refilling a 1.3-gallon water tank in the trunk, though. According to Car and Driver, it's that same system that BMW will be installing in the new M4 GTS, taking the place of previous M3 GTS specials. If precedent is anything to go by, the M4 GTS will also be stripped of excess weight and feature a tighter suspension, stickier tires and more, in order to make BMW's muscle coupe even more hardcore and focused for the track. We could be looking at a debut as early as Pebble Beach in August.

BMW celebrates with M4 DTM Champion Edition

Go back just a few seasons, and Germany's DTM touring car series was a straight-up competition between Audi and Mercedes-Benz. But BMW rejoined the race in 2012, winning both the drivers' and constructors' titles on its first year back and celebrating with a special matte-black M3 DTM Champion Edition. Last season, it won the constructors' championship but not the drivers', and this year it did the opposite. In short, it's been an impressive comeback for the Bavarian automaker, and to celebrate this year's accomplishments, it's followed up with the new M4 DTM Champion Edition for Europe you see here.
Based on the new M4 coupe - which forms the basis for BMW's DTM challenger as well as its pace car - the Champion Edition is distinguished by its special livery: The orange grille frame, the matte black hood and trunk with multicolored stripes, the black stripes along its shoulder and rocker panel, and the blacked-out 19-inch wheels all to pay homage to champion Marco Wittmann's racecar, as does special lettering on the rear windows.
Other enhancements include black front splitter and skirts, carbon front flaps and mirror caps, rear spoiler and carbon diffuser, while autographed sill plates and carbon interior trim with the car's serial number adorn the cabin. Only 23 examples will be offered, symbolic of the number adorning the winning tin-top racer and the flank of this special edition as well.

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.
