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 planning smaller Z2 roadster

It's been a few years since we heard about the BMW Z2, a compact, two-seat convertible that would slot in below the aging Z4 (shown above). Now, though, the crew at Car and Driver are back with details on the oft-rumored roadster.
The big shock for enthusiasts on this one is C/D's report that the Z2 will spin its front wheels, rather than its rears. A front-drive roadster is strange enough, but a front-drive BMW roadster? It's apparently true, though, as the new model would share its platform with the front-drive Mini and 2 Series Active Tourer rather than with the racier 228i or M235i coupes.
According to C/D, the rumored Z2 could be powered by a range of three- and four-cylinder, turbocharged engines, although it's more likely to be a four-only affair. Power should range from 160 to 230 ponies, while an M variant could arrive with 300 horsepower (that's a whole lot of power for front-wheel drive...).

BMW Pininfarina Gran Lusso Coup'e bows at Villa d'Este

The first collaboration between BMW and Pininfarina is this blunt-force two-door called the BMW Pininfarini Gran Lusso Coupe revealed at the Concorso d'Eleganza Villa d'Este. Said to be the "interpretation of a luxurious BMW Coupé as seen through the eyes of Pininfarina," once you get past all of the design-speak, you can focus on the full-bodied and keen-edged missile sitting on 21-inch wheels.
The long wheelbase makes for short overhangs. Up front, BMW's design language gets scraped across a whetstone, everything getting sharper, including the usually round cat's eye headlights that have gone dihedral. Under the hood is a V12, behind the twin-kidney grille in matte-sheen aluminium and high-gloss black. The same aluminum treatment also backs the taillights, the lenses designed to let air flow through them.
Inside is room for four, a cockpit canted toward the driver, Foglizzo leather in black and Tobacco Brown, 48,000-year-old kauri wood from New Zealand, deep pile carpet on the floors, a patterned virgin wool headliner and an "oblong aperture in the roof liner" set off by white LEDs.
