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 makes the M4 extra special with a huge wing

BMW has all of the bases covered in its lineup, especially when it comes to its 4 Series models. Don't like going to the track? There's the BMW 430i and 440i, which are available as a coupe and gran coupe. Drivers looking for a track-friendly car that can also be used on the road will be steered toward the M4. BMW even built the hardcore M4 GTS for drivers that spend all of their time on a track. Now, it looks like BMW is trying to bridge the gap between the M4 and the M4 GTS with a special-edition model. Our photographers caught BMW testing an M4 with some extreme aerodynamic components around the Nurburgring. With its aggressive front end, massive wing, and sporty rear diffuser, the prototype M4 appears to be similar to the special-edition M4 Competition Sport that BMW released in Spain. The Spain-only special edition was marketed as a softer version of the M4 GTS with less power and usable rear seats. With a similar look and visible rear seats, this prototype indicates a similar track-focused special edition model. Since the M4 is only a few years old, it's unlikely that BMW is testing a new model, but the automaker could be testing aerodynamic components for a refreshed model down the road. A cheaper, more usable M4 GTS, though, would be the perfect car to round out BMW's current lineup. Related Video:

BMW strategy gets green with future i8 Roadster, PHEV Mini

Recent concepts like the Vision Next 100 have signaled BMW's plan to become a leader in automotive tech in the near future, but the Bavarian automaker added some concrete details to that strategy during the company's annual press conference. The business promises there are updated i models and more plug-in hybrids on the way, and a vehicle called the iNext could bring an autonomous EV to the road early next decade. Before we see any completely new vehicles, look for BMW to refine its current green models. Later this year, the i3 will get a larger battery capacity, which will increase the hatchback's range. After seemingly endless teasing, the BMW i8 Roadster will finally arrive in 2018, according to a slide during the conference. The company will also launch a plug-in hybrid Mini, but it didn't give a specific arrival date. At the beginning of the next decade, BMW will also introduce a fully autonomous i model. At the beginning of the next decade, BMW will also introduce a fully autonomous i model, which it currently calls the iNext. "BMW iNEXT heralds the next era of mobility," company CEO Harald Kruger said. "This symbol of our technology leadership will demonstrate how we will bring the future of mobility into series production." BMW refers to its research into autonomous driving as Project i 2.0. Just as the initial development of the i models led to better EV tech and innovations in carbon fiber, the new undertaking should result in improvements to networked motoring and driverless tech for the iNext. The company plans to focus on high definition digital maps, sensor technology, cloud technology, and artificial intelligence. The company's product plan for the i range doesn't show any vehicles between the i8 Roadster in 2018 and the iNext early next decade. Perhaps the new model is the fruition of the many rumors about a family-oriented i5. As BMW eyes the future, it still sees the combustion engine as an important tool for the present, and there are still more traditional models to look forward to. Without offering any details, BMW promises more M models are under development. The larger X7 CUV will also arrive soon, and there'll possibly be even more crossovers, too. "We are also taking an in-depth look at the additional potential of this highly attractive segment," Kruger said.
