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 announces M235i xDrive, 7 Series Exclusive among summer upgrades

Like any automaker worth its lug-nuts, BMW is constantly striving to improve its products. And so it has announced a series of upgrades for the summer - none of them revolutionary, but a couple of them notable.
For one, the Bavarian automaker has announced that is is offering xDrive traction on the M235i coupe, a model that has been available until now only in rear-drive configuration. The all-wheel drive version comes with the same 3.0-liter twin-turbo inline-six with 326 horsepower (320 in the US market) and eight-speed automatic transmission as the rear-drive version, but now channels that power to all four wheels for a 0-62 time quoted at 4.6 seconds - two little ticks quicker than the existing version. It's the first time that all-wheel drive is being offered on the 2 Series, and will also be fitted on the convertible - at least, that is, in Europe. We're waiting on confirmation of North American availability.
Among the other announcements is a special edition of BMW's flagship luxury sedan. The 7 Series Exclusive Edition upgrades with metallic paint, 19-inch V-spoke alloys, Nappa leather upholstery and a leather-trimmed instrument panel. Buyers will also be able to opt for the Merino fine grain leather and Alcantara roof lining from the BMW Individual catalog, and choose between any available engine or either wheelbase lengths.

BMW 4 Series spied with its future competition

BMW showed off its new 4 Series coupe in concept form at the 2013 Detroit Auto Show earlier this year, but it won't be long before we see the production model, evidenced by this modestly camouflaged prototype spotted testing. In case you forgot, the 4 Series serves as the replacement for the two-door versions of the BMW 3 Series, just as the upcoming 2 Series will effectively be the new version of the 1 Series coupe and convertible sold in our market.
This isn't our first glimpse of the 4 Series out testing, and we've even spied its droptop, Gran Coupe and too-hot M4 kin. We don't expect the final design to stray too much from the concept car seen in Detroit, albeit without the normal conceptual goodies like oversized wheels and with the overstyled front fascia toned down a bit. Our spy photographers even caught the 4 Series coupe hanging out with an Audi A5, giving us a good glimpse at how the two cars will stack up in terms of size and design.
It's still unknown exactly what engines will power the car when it comes to production, but since this thing is a derivative of the 3 Series, we expect the usual range of turbocharged four- and six-cylinder engines to be available, likely in 428i ad 435i guise (though, to be fair, the larger 640i coupe uses a 3.0-liter turbo engine, so there's even the potential for 440i nomenclature to work its way into the mix). We'll have to wait until the car officially bows later this year to know for sure.
