BMW to offer carbon fiber wheels in a year or two

The Citroën SM sat on the first set of production glass fiber and resin wheels in 1972 when parent company Michelin developed the exotic hoops in order to take the SM rallying. It wasn't until 2008 that we got the first all-carbon-fiber wheel for passenger cars in the form of a prototype model from Weds Sports in Japan that remained a prototype. Australian company Carbon Revolution followed that a year later with its CR-9 all-CF wheel, first introduced on the Shelby Ultimate Aero and now available for independent purchase for about $15,000 per set. BMW could be the first OEM to offer entire wheels in carbon fiber reinforced plastic in two years.
The wheels - either all-CFRP or using a CFRP rim and alloy spokes - were shown off during BMW's Innovation Days in Munich and are products of the development work done on its i-branded cars. The full-CFRP wheel is 35-percent lighter than a forged alloy wheel, the hybrid alloy and CFRP wheel is 25-percent lighter, making for a decent drop in unsprung rotating weight. As demonstrators during a tech day the wheels aren't yet in the pipeline for production and EU approval, but an article in Auto Express claims that they could be on the market as soon as two years from now.
Other possible parts include a full carbon fiber steering wheel and propeller shaft, the latter of which is coming as a single-piece component on the new M3 and M4. BMW is also talking up its use of secondary carbon fiber - waste material from i3 and i8 production - that can be used for items like IP support structures, seat frames and spare wheels in place of traditional metals like aluminum and magnesium. There's an excerpt of the Innovation Day press release below with more details.

BMW 2 Series gets 3-cylinder Mini engine

BMW just keeps lopping off cylinders from its engines and sliding the ever-more-diminutive mills into its models. This spring, Europeans will get some of the automaker's smallest yet thanks to a new entry-level 2 Series that will share a powerplant with the Mini Cooper. The Bavarian company will also introduce a few other tweaks to the compact coupe across the pond. The 218i is the new 2 Series base model, and it shares its 1.5-liter turbocharged three-cylinder with the latest family of Minis. The engine makes the same 134 horsepower and 162 pound-feet of torque, but BMW does have some tiny changes for it. First, the orientation is swapped to fit lengthwise under the hood and drive the rear wheels. Just as importantly, buyers can order it with an eight-speed automatic, rather than the six-speed in the Minis. BMW claims that the little engine gives the 218i a 50:50 weight distribution, and it takes around 8.8 seconds to reach 62 miles per hour with the standard six-speed manual – tack on another tenth for the automatic. Either way, top speed is still a perfectly respectable 132 mph. Those acceleration numbers, incidentally, are over a second slower than what the latest Cooper is quoted at. Beyond this new base model, BMW will bring a few other additions to the 2 Series for Europe. The 220d oil burner will be available with xDrive all-wheel drive, and the company will introduce several new equipment bundles called Advantage, Luxury Line, Sport Line and M Sport. Each will bundle various options and trims together to appeal to buyers. No word yet on whether the 218i will eventually make it to North America, but we aren't holding our breath. Scroll down to read BMW's lengthy release about all of the changes set for the 2 Series. The BMW 2 Series Coupe: New entry-level engines, new model variants, even greater individuality. Premiere of the BMW 218i Coupe with 3-cylinder petrol engine from the new BMW Group engine portfolio and the BMW 220d xDrive Coupe – new and varied range of equipment features for model variants Advantage, Sport Line, Luxury Line and M Sport. Munich. From March 2015, new entry-level engines, a further four-wheel drive model and additional equipment options will increase the diversity of features available for the BMW 2 Series Coupe. With the market launch of the new BMW 218i Coupe, a three-cylinder petrol engine from the BMW Group's latest engine family will be featured for the first time in the brand's sporty and elegant compact model.

BMW patents strange three-cylinder pushrod engines, perhaps for cruiser motorcycle

For decades BMW's motorcycles were easily identified by the two opposed cylinders sticking out of each side of the bike. While you can still find this layout on some of its products, these days the company also uses a variety of other layouts, depending on the model line. Based on European patents, there might even be a Bimmer in the ranks eventually with an absolutely bizarre-looking W3 configuration. BMW actually has two separate patents on these W3 designs, and both of them have the goal of cramming three cylinders into the space of a traditional V-twin. The first splays the cylinder out into a fan shape with pushrods operating the valves. The description submitted to the World Intellectual Property Organization describes the solution as, "The embodiment according to the invention represents an as of yet unknown type of W-3 reciprocating piston internal combustion engine having cylinder angles which can be largely freely sized." The other solution is more of a modification to the traditional V-twin. Two of the cylinders share a crankpin, but the third has its own and is positioned inside the angle of the V. It's a very odd-looking engine. With BMW's assertion that these designs are meant to fit in place of a traditional V-twin, Jalopnik speculates that they could be for a future cruiser from the company, and that would make sense. While brand offers a line of sport tourers with the K1600 line, it doesn't have something more classic to take on the likes of the Ducati Diavel. Creating such a weird engine would probably grab early interest from riders.
