Looking back at 84 years of BMW roadsters

Today BMW is a top player in the luxury vehicle market, but it wasn't always so. With origins as an airplane engine builder early in the 20th Century, it broke into the automotive industry when it bought Automobilwerk Eisenach in 1928. That German manufacturer was licensed to build the Austin Seven under the name Dixi DA-1, which could be had in a roadster body style. In 1929, BMW dropped the Dixi name, and by 1936, it was building a car it designed in-house, the 326 sedan. That was followed by the company's first roadster of its own design, the swoopy two-door 327 of 1937.
XCAR picks up there, and gives a history of BMW's iconic roadsters starting with the 327, ending with today's Z4, and covering everything in between - including the beautiful post-war 507 of 1957 and the funky, plastic-bodied 1989 Z1.
The video, which we've included below, is a good history lesson and a great chance to see a bunch of classic BMWs, spanning 84 years, all driven back to back within the safe confines of a racetrack. When you have a spare 20 minutes, go ahead and take some time to watch it.

BMW discussing supercar collaboration with McLaren

BMW is reportedly considering a new halo supercar. But rather than go it alone, word has it that the Bavarian automaker is discussing a potential partnership with McLaren to make the idea a reality. This according to Britain's Car magazine, which suggests that negotiations are well underway. The proposal would see the BMW supercar based on the same architecture that will to underpin Woking's P16 project that's set to replace current 650S. Rather than use the 3.8-liter twin-turbo V8 that McLaren developed together with Ricardo, the Bimmer version would use Munich's own engine: a 4.0-liter V8 with quad turbochargers – two conventional spools and two more electrically driven chargers. Their combined effect would net an expected 750 horsepower. Further differentiations on McLaren's carbon monocoque architecture for use in the BMW would include custom bodywork, aerodynamics, and interior fitments to include a unique instrument panel. Production, however, would be handled at the McLaren Production Centre in Woking, to the tune of several hundred units per year. The project would take the place of several aborted programs undertaken internally at BMW. One called for an entirely unique supercar developed in-house, referred to internally as the M100. When that project was aborted so that BMW could concentrate on the i sub-brand, BMW's own skunkworks shifted its focus to developing a more performance-focused version of the i8, known by some as the i8 CSi. When that project was canned as well, discussions with McLaren commenced. It wouldn't be the first time BMW would outsource development of its own supercar, or even the first time BMW would collaborate with McLaren on such a project. Initial development work on the original M1 in the 1970s was undertaken by Lamborghini before being taken in-house. And, of course, BMW provided the engine for the legendary McLaren F1. Meanwhile McLaren performed a similar function for Mercedes-Benz with the SLR, demonstrating Woking's experience in building flagship supercars for German automakers. This latest project could suffer the same fate as the M100 and i8 CSi programs. But if it is approved, it could yield both coupe and convertible versions, with the first slated to surface at the Frankfurt Motor Show in 2017 and reach dealerships in 2019.

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.
