2014 BMW 4 Series convertible spotted

We've seen a few spy shot packages featuring the upcoming BMW 4 Series Convertible already, but never with the car quite so naked as in this latest batch. Nabbed just outside the BMW Nürburgring workshop in Germany, this Melbourne Red 4 Series also shows the M Sport package for the first time.
With all of the cladding removed, we can see that the convertible shares the 4 Series coupe's great-looking nose and front end, though the resolution of that folding hard top into the rear bodywork remains a bit harsh.
With the 4 Series coupe now completely official, we have a pretty good idea of what the powertrain lineup for the 'vert will be. We'll be pretty surprised if a 2.0-liter turbocharged four-cylinder and a 3.0-liter six-cylinder turbo aren't the go-to engines at launch. Production of the droptop is likely to begin at the end of the year, so start bugging your local BMW dealer.

BMW i8 Spyder gets production nod

BMW could be poised to expand its i8 range, beyond the hardtop version of the plug-in hybrid supercar. A report from Bimmerpost is claiming that the i8 Spyder, which we showed you in concept form at the 2012 Beijing Motor Show, will be heading to production.
The website claims the open-roof fuel-sipper was shown to BMW management last Friday as a production-intent model. Other than that, there's not a lot to tell here. The i8 Spyder should feature all the same mechanical and aesthetic features found on the i8 Coupe, just without the confining nature of a roof. It's unclear when we'll see a production i8 droptop make its debut, although this certainly strikes us as the kind of car that should arrive at the Geneva Motor Show.
While an i8 Spyder does seem like a logical leap for BMW's i sub-brand, we're going to keep this one filed under the rumors category until we hear more.

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.
