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.

Toyota-BMW sports car to gain all-wheel drive, supercapacitors?

Sales of salt are skyrocketing following the latest rumor of the planned joint-venture sports car from Toyota and BMW. The whisperings indicate that project will spawn both a replacement for the BMW Z4 and a long-awaited Toyota Supra successor based on the FT-1 Concept shown above. Word is that the new cars will feature front-engine, all-wheel-drive layouts with plug-in hybrid technology. This news would appear to run somewhat counter to earlier reports that BMW and Toyota are teaming for a six-figure hybrid supercar.
According to Autocar, the project will benefit from the experience Toyota gained with the TS030, its hybridized Le Mans prototype. The evidence for this is, of all things, a Toyota Yaris - in particular, the Yaris Hybrid R that was shown at the 2013 Frankfurt Motor Show last September. That car used a 300-horsepower, 1.6-liter gas engine, while a pair of 60-horsepower electric motors provided all-wheel-drive push (an additional motor also sent additional juice to the front axle). The 414-system-horsepower drivetrain used supercapacitors in place of the traditional lithium-ion batteries of traditional hybrids.
For the production sports cars, Autocar claims that the Yaris Hybrid R's setup will serve as the basis for the new powertrain, although it won't be a direct carryover. Instead, a 2.0-liter BMW engine will be paired with Toyota-designed, BMW-built motors.

BMW rolls out new M4 safety car for DTM

Ever since revealing the M4 on nearly five months ago, BMW has been hard at work getting its new muscle coupe out on the track. It's made a touring-car version to compete in DTM and a safety car to set the pace at MotoGP races, and now it's combined both into a new safety car for DTM as well.
The ninth M4 on the DTM grid is based on the production version, but fitted with numerous upgrades over the course of a two-month conversion process. For starters, it's been equipped with nearly exterior component from the M Performance Parts catalog, including the quad-tipped exhaust, front splitter, rear spoiler and diffuser, blacked-out grille, special mirror caps, side sills... the works. But that's not the end of the story.
BMW M GmbH also gutted the interior, removing the rear bench and replacing it with a roll cage. It's got a pair of Recaro racing buckets with Schroth harnesses, plus special LED emergency lighting, radio communication system and, of course, special livery (albeit nowhere near as cool as the MotoGP one) to distinguish it as the official safety car when it makes its debut at the Nürburgring on August 17.
