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.

Translogic 153: 2015 BMW i8

The 2015 BMW i8 is the second model in the Bavarian automaker's eco-friendly i-branded lineup. The i8's plug-in hybrid powertrain combines a turbocharged 1.5-liter three-cylinder engine with a 96-kilowatt electric motor to make 357 horsepower and 420 pound-feet of torque. Together, this gas-electric mechanical duo is capable of propelling the groundbreaking carbon-fiber sports coupe from 0 to 60 miles per hour in just 4.2 seconds.

Evo pits BMW M3 against Porsche Macan in drag battle

If you want to move five passengers in very rapid fashion and you've got a $75,000 budget, two newly introduced four-door models immediately come to mind - both are the highest performing vehicles in their respective segments. But which is faster off the line, to the 60-mile-per-hour benchmark or flat-out over an even longer run? Evo took both to paved aircraft runway to find out.
In lane one we've got the all-new Porsche Macan Turbo, which boasts a twin-turbocharged, 3.6-liter V6 rated at 400 horsepower and 406 pound-feet of torque. The Porsche is fitted with a seven-speed, dual-clutch gearbox, and the 4,244-pound crossover has the traction advantage of standard all-wheel drive. In lane two is the all-new BMW M3, powered by a twin-turbo 3.0-liter inline-six rated at 425 horsepower and 406 pound-feet of torque. It is also equipped with a seven-speed, dual-clutch gearbox, but only the rear wheels of the 3,595-pound sedan are driven. Both the BMW and Porsche arrive with launch control, which helps to remove driver error off the line.
Which automaker's launch control system is better off the line? Does all-wheel-drive grip give the crossover the advantage it needs to overcome its adversary's power-to-weight advantage? Will aerodynamics factor into the results? Which would you put in your garage, and why? The video may surprise you.
