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 M4 vs. Lexus RC F in Head 2 Head sports coupe showdown

It's the showdown everyone's been looking forward to, the East versus West grudge match of the year. We're talking, of course, about the BMW M4 versus the Lexus RC F.
Although BMW uses a twin-turbo straight-six and the Lexus uses a free-breathing V8, the two are pretty closely matched on paper: a luxury coupe with over 400 horsepower channeled to the rear wheels.
The BMW has been doing these cars for longer, and the M4 boasts a higher power-to-weight ratio. But then the RC F has more power - and without forced induction to break up the rev range. So which is the better luxury muscle coupe? Watch the latest episode of Motor Trend Head 2 Head to find out.

BMW M4 Concept beckons the new golden child of M cars

Ushering in the next-generation of two-door M performance cars for BMW, the new M4 Concept was officially unveiled at the Pebble Beach Concours d'Elegance last night after an unceremonious embargo leak yesterday afternoon. The reality of the fact that we will never again have a new M3 Coupe is a little easier to deal with after browsing the M4 Concept's sleek and sporty lines.
As was the case with the Concept 4 Series Coupe, we expect the this M4 to transition from concept car to production coupe with very few changes. Among the features we's bet against making it into production include the front splitter and the exhaust tips - both made from carbon fiber. Other notable details are the aero-shaped mirrors, the subtle M stripes on the carbon fiber roof and the 20-inch wheels exposing big six-piston from brakes. If it were up to us, we'd say bring this car to production as is - except for the paint color.
There is still no word on the M4's powertrain or if it will even offer a manual geabox, but we would imagine that we'll be seeing this car in production form, complete with all of those details at the LA Auto Show.
