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 Concept 4 Series Coupe proves that 3-2=4

BMW may be calling this 4 Series Coupe a concept, but take a long, hard look - this will be the car that replaces the 3 Series Coupe in the automaker's lineup. Don't let that number change trip you up. This car will have all the basic elements of what makes a 3 Series coupe so popular, and while this isn't technically the production model (there are still come conceptual elements and we don't have powertrain details), it's pretty much what we can look forward to seeing out on the road very soon. And honestly, the naming strategy isn't that weird (though it's still plenty odd) - BMW will be using even numbers for all its coupes and convertibles moving forward. 1 Series, meet 2 Series. And when a 3 Series loses two doors, it becomes a 4 Series.
Dimensionally, the new 4 Series coupe is 1.7-inches wider, half an inch shorter in overall height, and rides on a 2.0-inch longer wheelbase. It's a really pretty thing, with bold, aggressive body sculpting up front, and a rear deck that's sort of like a downsized version of the larger 6 Series two-door. It's all very handsome, but we'll reserve final judgment until we see the production version with its likely smaller wheels and possibly toned-down visuals.
We don't yet have powertrain details, but we fully expect the 2.0-liter turbocharged four-cylinder and 3.0-liter turbo-six to carry over in 328i 428i and 435i guise. Though remember, other 3.0-liter models in BMW's range use 40i designation, so we could possibly be looking at a 440i Coupe, instead. We won't know until the production car officially bows later this year.

BMW M3, M4 let loose on the 'Ring

We just posted our first drive of the 2014 BMW 435i yesterday, but for those wanting even more power from this stylish coupe, help is on the way. From the sounds of it, BMW will be showing off a production-ready concept previewing the M4 next month at the Pebble Beach Concours d'Elegance, but until then, we have some new spy shots of the performance coupe being tested at the Nürburgring, along with its four-door counterpart, the M3.
Despite all the camouflage, it doesn't take much imagination to picture what both cars will look like, since we can clearly see the more aggressive front fascia and beefier brake setup. One interesting element we see on both cars is a double bubble roof that is almost certainly made from carbon fiber. Based on our report earlier, both the M4 Coupe and M3 Sedan are expected to debut at the 2014 Detroit Auto Show.
