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.

Xcar rates AWD vs. FWD vs. RWD

With snow and ice blanketing large swathes of the United States over the past few weeks, commuting hasn't been easy. Among some drivers, there's an ongoing debate about how much all-wheel drive really helps when it gets slippery and whether rear-drive is as bad in slick conditions as many people think. Xcar Films puts some of those beliefs to the test in its latest video by showing off three very different cars taking on a trio of low-grip challenges. Xcar's picks for the test include the fairly plebeian, all-wheel drive Subaru Impreza, the somewhat plush, rear-drive BMW 120d and the sporty, front-drive Renault Megane RS 275 Trophy. Things start out easy with a hydraulic plate forcing the back end out on a wet skid pad. From there, the tests get really interesting with a slalom on simulated ice, and the cars finish with a high-speed cornering challenge through a soaked turn. While an obvious winner emerges in the end, keep in mind this is hardly a scientific test of grip. For better accuracy, all three vehicles should be wearing identical tires, and the same driver should be behind the wheel of each one. Still, Xcar's examination is a fun chance to see how vehicles react when things get slick.

Car designer Frank Stephenson wants to show you something ... smaller

Influential car designer Frank Stephenson has often thought small. Now he’s thinking smaller. Throughout the past three decades, he has shaped — literally — some of the most indelible designs in automotive history: the modern Mini, the Ferrari FXX track star, the Maserati Gran Sport, a range of stunning McLarens and down to the funky 21st-century version of the Fiat 500. Now heÂ’s turned his pen to fashioning watches. His Cosmos analog piece, made to mirror “a black hole in space” and detailed “with an orange pinstripe which simulates the supernova glow of a neutron star,” features a Japan-built quartz movement and was created in concert with the Time Concepts company. “ItÂ’s the age-old adage ‘car people are watch people,Â’ so it was a natural step for me to get creative with timepieces too,” Stephenson said in a statement. “The collection showcases the love I have for exceptional and emotionally charged design, just like what is required in designing world class cars.” While Stephenson, who is 64, may be best known publicly for his vision of “affordable style” with the Mini and the Fiat, his ethos also translated to the utilitarian. In the case of BMW in the mid-1990s, the company was hustling to market an SUV, and turned to him for inspiration. His team had six months to complete the project. The result was the high-end X5, which Stephenson sketched during a two-hour flight. In 2018, Stephenson established the independent design company, Frank Stephenson Design, based in London.
