BMW 4 Series Gran Coupe caught without cladding

Like it or not, the majority of BMW 3 Series variants are on their way out, and the 4 Series models are hotly embroiled in the testing needed to replace them. We've now driven the basic 4 Series, seen spy photographs of the 4 Series Convertible and both versions of the M4 and today we get a better-than-ever look at the 4 Series Gran Coupe.
And, mostly dependent on your personal disposition towards four-dour coupes, that look should be a pleasant thing. The long, swooping Gran Coupe may be roughly similar in size to the related 3 Series GT, but it has been sculpted with beauty in mind rather than crossover function. We expect that those details still hidden by the body cladding here, mostly front and rear, can be filled in by simply remembering what the standard 4 Series looks like and squinting your eyes a bit. Subtlety is thy name, BMW variants.
As for the mechanicals, well, we expect to have the very same greasy bits under the hood and beneath the car that are found in the 4 Series lineup, too.

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 3 Series eDrive plug-in hybrid spotted in development

BMW has shown its commitment to the development of hybrid and electric powertrains in recent years, with vehicles in its ActiveHybrid range, electrics like its BMW ActiveE and range-extended EVs like the i3 and i8. Plug-in hybrid-electric vehicles are clearly top-of-mind for the German automaker. We saw spy shots of the PHEV BMW X5 eDrive prototypes about a year ago, and now our shooters have come through with a 3 Series-bodied version of the technology, as well.
In addition to the obvious "Hybrid Test Vehicle" designation you see on the bodysides of this 3er, we also note that a second 'fuel cap' - presumably hiding the electric charge point - is in evidence. It's a fairly safe assumption that this 3 Series is making use of the same turbocharged four-cylinder engine and electric motor configuration that the X5 eDrive used. In the case of the X5, that meant a top electric-only speed of 75 miles per hour, with a range of just under 20 miles, and 0-62 mph in under 7 seconds. With considerably lighter, compact sedan bodywork clothing the PHEV drivetrain, we'd guess that the 3 Series eDrive could improve on each of those numbers.
