BMW M235i in circuit scrap with legendary E46 M3 CSL

Earlier this month, we brought you news that BMW's one-year wonder, the 2011 1 Series M Coupe, is actually trading for more money today than it did when new. That sort of short-term appreciation is a major rarity with modern production cars, but apparently it's not the only BMW enthusiast coupe to enjoy far-above-average residual values. The not-for-North America 2004 M3 CSL, itself a single-year offering, apparently also fits that description, as we've just learned from Auto Express.
The M3 CSL ruled overseas BMW showrooms a decade ago, with just 1,400 examples built. Based on the well-regarded E46 M3, the rare two-door was relieved of extraneous bits for improved track work and driver fidelity, coming in at around 240 fewer pounds than a garden-variety M3. With carbon-fiber-reinforced plastic bodywork, thinner glass and a lot less sound insulation, the CSL was one of the more raucous cars of its day. Like the 1M Coupe, it was also one of the more connected cars of the era, with a retuned suspension, quicker steering, and a bit more power than its brethren.
As Auto Express points out, a good used one commands about the same money as a brand-new 2014 M235i - the closest thing BMW makes to a 1M Coupe today - which makes this video track battle an interesting new-versus-used showdown. According to AE, a well-sorted used M3 CSL will run UK consumers anywhere between £30,000 and £35,000 - roughly $50,000 to $59,000 US. That's a massive premium over the $10k-17k British buyers can expect to shell out for a comparable standard M3, similar to the story that plays out for the 1M versus lesser 1 Series variants.

BMW 4 Series Gran Coupe spotted wearing minimal camo, M Sport pack

The new BMW 4 Series is essentially the coupe version of the latest 3 Series. So it would stand to reason that the four-door version of the 4 Series, in turn, would be the 3 Series - right? Well, yes and no.
Just as BMW offers both a 5 Series sedan and a four-door version of the 6 Series called the Gran Coupe, so, too, will its 4-Series family expand. So following the release of the new 4 Series Convertible, here we have the latest batch of spy shots showing the upcoming 4 Series Gran Coupe - which in turn should not be confused with the hunchbacked 3 Series Gran Turismo, which is more of a sporty wagon than a four-door coupe.
The nearly ready test vehicle pictured here is wearing only minimal camouflage to hide some last few details, but also appears to be wearing the M Sport package that will bridge the gap (at least, visually speaking) between the base models and the M4 Gran Coupe that is all but certain to follow.

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.
