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.

Recharge Wrap-up: VW Golf TDI wins green car award, DC buses might go electric

The 2015 Volkswagen Golf TDI has won the award for 2014 Northwest Green Car or the Year. The distinction comes from the Northwest Automotive Press Association during its Drive Revolution event in Portland. Co-chairman of the event, Jeff Zurschmeide, says, "Volkswagen has led the diesel passenger car market for years, and the Golf TDI proves that they're likely to stay on top for a while." The 2015 Golf TDI has 10 more horsepower than the outgoing model, while improving fuel economy thanks to a new engine. It also has a base price $3,000 lower than the 2014 Golf TDI.

The laser lights use half the energy of their LED counterparts, according to BMW, which is important when one is trying to get every last bit of range out of the car's battery. The laser high beams can also reach about twice as far as LED lighting. Because of their brightness, they won't be available on cars sold in the US. In laser-equipped i8s, the laser high beams will not work below 60 kilometers per hour, nor when other lights are detected in front of the vehicle. Head to Automotive News Europe to read more. Renault has delivered a fleet of 30 Kangoo ZEs to Uruguay's government-owned power company, UTE. The electric fleet will allow the company to reduce its CO2 emissions by 36 metric tons, says Renault. 84 percent of Uruguay's electricity comes from renewable sources, with a goal of 90 percent on the horizon. Uruguay aims to get a third of its electricity from wind farms by 2016, meaning these Kangoo ZEs will be powered in no small part by renewable energy. For Renault, "This order is a further sign of the interest in the region for electric vehicles," according to Denis Barbier, Renault's senior vice president, citing previous deliveries in Brazil, Mexico, Argentina and Colombia.

Some of the diesel buses, which were first put to work in 2003, are nearing the end of their life cycle, and DC sees an opportunity to make the switch to something a little greener. "Electric has not been a viable option in previous procurements, but now it is," says Will Handsfield, Georgetown Business Improvement District's transportation director. Handsfield is concerned about air quality, and says he also appreciates the long-term stability of electric rates compared to diesel.

BMW 4 Series Gran Coupe caught again

It's been a while since we've seen the upcoming BMW 4 Series Gran Coupe out testing, but we're sort of inclined to ask "Why?" yet again. After all, the 4 Series is what the new 3 Series-based coupes and convertibles will be called, so the idea of another four-door version just sort of seems redundant. In other words, just how different will a 4 Series Gran Coupe be from a 3 Series sedan, aside from perhaps a more rakish roofline or a four-passenger seating configuration? Probably not much, but BMW clearly thinks it can use the additional bodystyle to rake in some extra profits.
Anyway, back to these spy shots. No more of the 4GC's skin has been revealed since the last time we saw it, but we fully expect it to share a lot of its design DNA with the 3 Series sedan, not to mention the attractive 4 Series coupe concept that bowed at this year's Detroit Auto Show.
Powertrain options should carry over direct from the 3 Series line, so we expect to see 428i and 435i models on hand, packing turbocharged four- and six-cylinder engines, respectively. We're sure that BMW's xDrive all-wheel drive will be available, and who knows, we could even get a 428d version with the new 2.0-liter turbodiesel four that debuted in the 328d at the New York Auto Show last week, or even an M4 variant.
