BMW makes the M4 extra special with a huge wing

BMW has all of the bases covered in its lineup, especially when it comes to its 4 Series models. Don't like going to the track? There's the BMW 430i and 440i, which are available as a coupe and gran coupe. Drivers looking for a track-friendly car that can also be used on the road will be steered toward the M4. BMW even built the hardcore M4 GTS for drivers that spend all of their time on a track. Now, it looks like BMW is trying to bridge the gap between the M4 and the M4 GTS with a special-edition model. Our photographers caught BMW testing an M4 with some extreme aerodynamic components around the Nurburgring. With its aggressive front end, massive wing, and sporty rear diffuser, the prototype M4 appears to be similar to the special-edition M4 Competition Sport that BMW released in Spain. The Spain-only special edition was marketed as a softer version of the M4 GTS with less power and usable rear seats. With a similar look and visible rear seats, this prototype indicates a similar track-focused special edition model. Since the M4 is only a few years old, it's unlikely that BMW is testing a new model, but the automaker could be testing aerodynamic components for a refreshed model down the road. A cheaper, more usable M4 GTS, though, would be the perfect car to round out BMW's current lineup. Related Video:

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.

Translogic 182: CXC Motion Pro II Racing Simulator

Translogic gets some seat time in the CXC Motion Pro II to test if the high fidelity racing simulator can impact our host's real-life track times. Host Jonathon Buckley hits the track at Auto Club Speedway of California in a 2015 BMW M4 to put down a baseline lap time before his virtual training session in the Motion Pro II. After learning the lines of the track in a simulated setting, Jonathon returns to the track to put his skills to the test. "We designed it, originally, as a professional training tool for race car drivers," says CXC Simulation's founder and president Chris Considine. "Make it authentic. Make it real." The Motion Pro II boasts "thousands of cars and track models," ranging from street cars, to rally and off-road vehicles. Will this hyper realistic racing simulator help Jonathon improve his lap time?
