BMW i3 qualifies for both green and white HOV stickers in California

BMW buyers tend to have enough cash on hand to be buffered from the concept of "sticker shock," but the term may take on a different meaning when it comes to the German automaker's i3 plug-in vehicle and its classification by California clean-air regulators. The first i3 EVs are set to be sold in May, and some are questioning if the new car will be eligible for the state's white stickers or green High-Occupancy Vehicle lane stickers, both of which allow for solo-occupancy in HOV lanes. California gives out white stickers to some types of battery-electric vehicles, compressed natural gas (CNG) vehicles and hydrogen fuel-cell vehicles, and there's currently no limit on the number that can be given out. The green stickers, which are applied to other battery electrics as well as some plug-in hybrids, are limited (there are currently about 15,000 left) and will likely run out within the next year or two. The i3's status is uncertain because of it has an optional gas-powered range-extender. Jacob Harb, head of electric vehicle operations and strategy for BMW, told AutoblogGreen that it's not all that complicated. The pure electric version of the i3 will get the white sticker, the REx version will get the green sticker. He also said that both will qualify for the $2,500 state incentive in California and the $7,500 federal tax credit available in all 50 states (For what it's worth, Green Car Reports says the REx version will only get $1,500 from California).

BMW M4 Convertible poised for Goodwood unveil

It shouldn't be a shock that BMW is working on a convertible version of the M4. Not only have we caught it testing twice, but this is an automaker that seems willing to build a vehicle for nearly every buyer's needs. Evo claims that the high-performance droptop is going to debut at this year's Goodwood Festival of Speed in England from June 26-29.
Judging from the spy shots we've seen, the M4 Convertible will consist of a retractable hard top like the 4 Series cabrio. Other than the roof, there aren't expected to be many changes from the coupe. The engine will be the same turbocharged, 3.0-liter inline six-cylinder engine, but the added weight of the roof and its mechanism may take a small bite out of performance.
We spoke to BMW USA about the rumor and were told that it has no comment at this time. After the M4 Convertible, Evo claims that BMW is working on a M4 Gran Coupe. How that would be all that different from an M3, isn't exactly clear.

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.
