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.

This Or That: 1980 Oldsmobile 442 vs. 1989 BMW 635CSi [w/poll]

The last time I roped a coworker into an automotive debate, I lost. Resoundingly, I might add. Still, 2,385 voters chose to cast their lots for the Fiat 500 Abarth, as opposed to 5,273 choosing the Ford Fiesta ST, and so I can rest easy in the knowledge that at least 30 percent of you, dear readers, see things my way. I still like to think we have more fun, too.
My loss in the first round of our This or That series, in which two Autoblog editors pick sides on any given topic and then attempt to explain why the other is completely wrong, didn't stop me from picking another good-natured fight, this time with Senior Editor Seyth Miersma. Last time, our chosen sides were eerily similar in design, albeit quite different in actual execution. This time, our vehicular peculiarities couldn't seemingly fall any further from one another: A 1980 Oldsmobile 442 wouldn't seem to match up in comparison to a 1989 BMW 635CSi.
How did we come up with such disparate contenders? Simple, really. Seyth and I mutually agreed to choose a car that's currently for sale online. It had to be built and sold in the 1980s, and it had to be a coupe. The price cap was set at $10,000. The fruits of our searching labors will henceforth be disputed, with Seyth on the side of the Germans, and myself arguing in favor of the Rocket Olds. Am I setting myself up for another lopsided loss?

BMW confirms X4 for next year, i3 preorders starting to add up

BMW has confirmed the long-anticipated X4 will bow next year. Norbert Reithofer, chairman of the automaker's board of management, made mention of the upcoming CUV during remarks at the company's annual accounts press conference. Reithofer said that BMW has sold more than 2.7 million X models since it began producing the machines, and that the company plans to expand those offerings with the new X4 next year. He declined to offer up any more details, though from what we've heard so far, the model will be more of a crossover than either the X3 or the X5.
Reithofer also made it clear that BMW is getting serious about electric vehicles, saying the i3 (pictured above, in prototype form) is "definitely coming to market" and that the runabout will be ready by late 2013. BMW reports it has had "Several hundred advance orders" for the EV. As you may recall, the i3 uses a special carbon fiber reinforced plastic passenger cell to save weight and boasts a standard range of 93 miles.
