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.

2015 BMW M3 squares off against Alpina D3 in gas vs. diesel throwdown

There was a time when diesel meant one of two things: This vehicle's owner either wants to save some money at the pump or needs to haul massive loads. It definitely did not mean that the owner of said machine wanted to drive fast, but that perception has slowly but surely been changing over the last several years, with automakers from Volkswagen and Ford to Audi and BMW offering spiced-up versions of their high-compression, turbocharged diesels.
It's that last automaker we mentioned that's the subject of the video you'll see down below. One bright-blue BMW M3 was procured by the Brits at Autocar, and it was lined up against a deep-black Alpina D3 (which we sadly can't buy in the US) in a spate of tests, including acceleration, stopping, sound and lap times on a closed circuit. The results, which we won't spoil for you, were enlightening, and were followed up by personal impressions from the man behind the wheel.
We know you're curious. All it takes to find out which of these 3.0-liter, twin-turbo-powered 3 Series variants came out on top is to scroll down below and watch. You know what to do.

Next BMW M5 could go all-wheel drive

Franciscus van Meel had been a part of Audi AG management since 1996, in positions including chassis development and vehicle project director. In 2012 he was named managing director of Quattro GmbH - headquarters for personal favorites like the RS6 Avant and R8 - but he lasted just two years before being sent to lead an R&D division in Beijing. He returned from exile just ten months later but wearing a blue and white roundel, after being named to the top spot at BMW M. So it shouldn't be a surprise that when Auto Express asked van Meel about all-wheel drive on the next M5, he replied, "If we continue the power increases in the future... then probably the next generation M5 and M6 will have so much torque and power that we need to think about those solutions." It would make sense from a competitive standpoint, too - once the Mercedes-Benz E63 AMG went 4Matic, that put the two of the three cars in the segment in the AWD column. And there's no "if" about a power increase: a recent report put next generation's output at 600 hp - that's 40 hp more than today - to power a lighter car. That report said there'd be the option of four-wheel drive, but AE takes van Meel's words as a definite sign that we'll see a more complex drive arrangement under the next M5. If so, then truth be told, van Meel is reiterating the thoughts of his predecessor from two years ago. The new M boss doesn't like the phrase "four-wheel drive," however; in clarifying those "solutions" he mentioned, he said that the car would be rear-biased to remain emotional, with the front tires kicking in to aid traction.
