BMW tests M Lap Timer App with M4 Coupe at Brands Hatch

The 2015 BMW M4 looks to include all the necessary ingredients to offer dynamite driving experience. It's an M car after all. But in today's constantly connected world, the experience of hurtling a car around a track isn't always enough.
We want data, and while there are some solid telemetry apps available for smartphones (notably Harry's GPS LapTimer), manufacturers have been a bit slower to develop their own dedicated mobile telemetry trackers for their performance cars. With the new M4, though, BMW is taking the plunge, allowing drivers to track their lap progress through a new app, creatively called the M Lap Timer.
To show off the program, BMW has recruited touring car racer Andy Priaulx to perform a fast lap in an M4 at the UK's Brands Hatch circuit. The accompanying video doesn't do much to show off the app in action. Rather, it give us a stylized look at the metrics as Priaulx hustles BMW's hottest 4 Series coupe around the circuit.

Why BMW doesn't plan to integrate Apple's iOS in the Car

While watching Apple introduce iOS in the Car during its WWDC keynote on Monday, we wondered how automakers, even the 14 who've already signed up to integrate this new in-car functionality of iOS 7, will feel about having the Cupertino company's mobile operating system supplant their own in-car systems. After all, some OEMs like Ford, General Motors and many luxury automakers have sunk millions of dollars into developing their own advanced infotainment, navigation and communication platforms like MyFord Touch, CUE and older systems like iDrive.
One automaker has now spoken up. A BMW spokeperson was interviewed by someone in the news department of British auto dealer group Arnold Clark and confirmed that the company would not be getting in line to integrate iOS in the Car anytime soon. The reason, as we suspected, is that BMW believes its own products developed over the last decade are both plenty good and already so deeply integrated with other systems of the car that, as told to Arnold Clark, "it would not be that straightforward to start changing all of the architecture of a car as has been implied [by Apple]."
While BMW isn't interested in spending more money to integrate Apple's services and functionality over its own, it has spent a good bit already to integrate iPhone functionality in its cars, including the relatively rare ability to support iPod Out and display Apple's own interface on Mini models with the optional Mini Connected feature, as well as committing to integrate Siri 'Eyes Free' functionality.

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.
