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.

The 2016 BMW M2 is a steroid-addled M235i [UPDATE]

UPDATE: As it turns out, BMW mixed up the weight specs in the official press materials. We spoke to BMW for confirmation, and the manual M2 weighs 3,450 pounds, the DCT car weighs 3,505. We've updated the text to reflect this. If you're looking for a featherweight M235i, you'll be disappointed. The extra power and goodies are offset by negligible weight savings. When we first got behind the wheel of the M235i early last year, BMW was quick to point out the spiritual link between the small quasi-M car and its ancestors, the 2002 Turbo and the E30 M3, but we couldn't help but think fondly of the more potent 1M Coupe. And while the M235i got a lot of things right, its weight and price took some of the shine off it. But more importantly, the intangibles that those older BMWs nailed was somewhat lacking in the M235i – while fun, it was somewhat distant, unlike the visceral 1M. Until we drive the 2016 BMW M2, those intangibles will remain intangible. But on paper, the M2 looks to be a super-M235i, buffed up with M goodies like an active rear differential and lightened suspension components. But if you're looking for a featherweight M235i, you'll be disappointed. The extra power and goodies are offset by negligible weight savings. With the manual it weighs 3,450 pounds, an 85-pound reduction. With the DCT, it's a wash at 3,505 pounds. At least the M2 looks like a proper M car. The side bodywork swells 2.1 inches up front and 3.1 inches in the rear to accommodate wide 19-inch forged wheels wrapped in Michelin Pilot Super Sport tires. The front end takes the M235i theme (itself an adrenaline-injected version of lesser 2 Series cars) and adds steroidal menace, with the expected larger intakes to feed the extra engine radiator. Out back, there's a diffuser in the rear tray that the M235i lacks, and the scallops that incorporate the taillights plainly telegraph the extra rear width. It's the M4's handsome younger sibling. Like the M235i to which its clearly related, the heart of the M2 is a 3.0-liter inline-six that inhales through a TwinScroll exhaust manifold-integrated turbocharger. High-precision direct injection, Double-VANOS, and Valvetronic are all present and accounted for, with some M goodies like pistons and crank bearings trickling down from the M3 and M4. The result is 365 horsepower at 6,500 rpm and 343 pound-feet of torque available from as low as 1,400 rpm.
