BMW X4 M40i leaks ahead of LA Auto Show

Leaked photos of the higher-performance BMW X4 M40i emerged today ahead of its expected debut at the 2015 LA Auto Show. The new model builds on the xDrive35i model, offering an extra 60 horsepower and 43 pound-feet of torque. The hotted-up X4 should use that power well. According to Auto Guide, it will hit 62 miles per hour in 4.9 seconds and should be limited to a top speed of 155 mph – a notable improvement over the existing xDrive35i, which takes 5.2 seconds to hit 60 and has a top speed of 130 mph. Expect the X4 M40i to be followed by an similar version using the X3's more versatile body style, both of which will use an eight-speed automatic and a more aggressive all-wheel-drive setup. Despite the "M" in its name, this is not a full-blown M car. Instead, it takes the same tack BMW has used for the M235i here in America, as well as the M50d models sold in Europe: higher performance over stock, without offering the full enchilada that is a proper M car. That explains the slightly more aggressive body kit, which isn't as sporting as that of a proper M car. On top of the new front and rear clips, there's a set of meaty 19-inch wheels that look to be wrapped in sporty Michelin Pilot Super Sport tires. In the cabin, an oversized M-branded steering wheel is the most notable addition. Naturally, we'll have the full range of details on the X4 M40i when it debuts in a couple of months in LA.

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.
