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 already considering four cylinders for next M3

The cylinder count in BMW's M3 has fluctuated over the years. The original M3 debuted in 1985 packing a 2.3-liter inline-four, but subsequent models went with sixes until the outgoing generation upped the cylinder count to eight. With its latest model, BMW has dropped back to six cylinders with a pair of turbos taking the place of the extra pistons. But the next M3 sedan and M4 coupe could go back to the model line's roots with a four-cylinder engine.
Speaking with BMW M product manager Carsten Pries at the launch of the latest M3 and M4 in Portugal, our Aussie compatriots at Motoring.com.au report that "you could see a future [M3] powered by a four-cylinder engine." Offsetting the reduction in cylinders, the lighter engine would benefit the vehicle's weight and balance, thus enhancing performance.
We wouldn't expect the next M3 and M4 to lose any power in the process, though: Output in the M3 has only risen over the generations, from 192 horsepower in the four-pot original to 282 hp in the six-cylinder E36, 338 hp in the six-cylinder E46, 414 hp in the V8 E90 and 425 ponies in the new turbocharged six-cylinder F80 model. With that latter model having just debuted, it'll likely be a good six or seven years before the next version comes along, giving BMW plenty of time to settle on an engine - however many cylinders and turbochargers it has. In the meantime, you'll have to forgive us for taking a romp down M3 memory lane in the fresh gallery of images above.

BMW just the latest automaker to realize China will want a lot of EVs

News about China and cars isn't in short supply these days. With several of the world's largest cities, millions of cars on the road and huge problems with air pollution, it's no wonder that the nation is trying to make some changes. Along with decommissioning many of its aging vehicles, China is also expected to see huge growth in its electric vehicle market. BMW, as other automakers already have done, sees this as an opportunity to sell more cars. "We expect that the Chinese car market for electromobility will become the largest markets for those cars in a few years," says Karsten Engel, BMW's China head. BMW is collaborating with Shanghai's State Grid municipal power company to put public EV charging points at the former World Expo site, and the city plans to create 45 more by the end of the year. These will charge many different vehicles made by BMW and other brands. Tesla, which began delivering its Model S to China last month, plans to build its own supercharger network for the country. BMW plans to begin selling the battery-powered i3 and i8 plug-in hybrid in China this fall. BMW hopes to sell more than 400,000 vehicles in China this year. Fewer than 1,000 of those will be the i3, though, says Engel, due to a lack of supply. So far, China is falling drastically behind its own targets to get EVs on the road. With a goal of 500,000 by 2015, fewer than 70,000 EVs are currently operating in China. This numbers gap doesn't necessarily mean that the demand is or isn't there yet, but more and more automakers are betting it will be, and soon. Volkswagen is planning a fleet of electrified models for China by 2018 (at least 15 models according to Bloomberg). Daimler is teaming up with China's BYD to build EVs (and, of course, Your Dreams). Other Chinese companies are getting into the game as well.
