BMW i3 REx rated at 117 MPGe, 39 mpg with 72-mile EV range

The numbers haven't made their digital way to the EPA's website yet, but we can now confirm that the BMW i3 with range extender will be officially rated at a combined 117 MPGe with 39 mpg once the battery runs out. That puts the amazing little city car just ahead of the pure-electric Fiat 500e (116 MPGE, combined) and behind the Honda Fit EV (118) and the Chevy Spark EV (119). In the plug-in hybrid category, it's at the top of the class, beating out the Honda Accord PHEV, which is rated at 115 MPGe but is also a much bigger vehicle. The i3 REx also has an official all-electric range of 72 miles and can go another 78 on gas (for a total of 150). When it's not carrying around the extra fuel tank and engine, the all-electric i3 gets 124 MPGe (combined), which is the currently the highest in the US. The i3 EV also has an all-electric range of 81 miles. BMW expects to deliver the first i3 REx in the US this week and delivered the first all-electric version earlier this month. There was a bit of a hold-up on the range-extender version thanks to a delay with getting these EPA numbers. Now that all the bureaucratic boxes have been checked, it's off to customer driveways they go.

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 will make plug-in hybrid versions of all models

Late last year, BMW made it clear that it would be making plug-in hybrid versions of all of its "core models." The first of those will be the X5 xDrive40e. At the New York Auto Show this week, BMW North America CEO Ludwig Willisch told AutoblogGreen that this enhanced PHEV plan is going to be applied to "every new model." We were asking Willisch if he views Tesla as a competitor to the Bavarian automaker. "I wouldn't say I don't see any competition," Willisch said, "but I still see that a BMW 5 Series and a Tesla are totally different animals." What about the rumored i5 or an i7, we started to ask – "which we don't have" Willisch interrupted – that could happen, couldn't it? "Not any time soon," Willisch said. "What we will have are plug-in hybrids. With the introduction of every new model there will be a plug-in hybrid version of that, too." There are people who are asking if the i brand will expand to a truck or a larger sedan, "but this is all the future," Willisch said. "It's not now and it's not the next couple years." Related Video:
