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.

2014 BMW 740Ld xDrive does diesel in a big way

Slowly but surely, BMW is expanding its lineup of diesel-powered models here in the United States. In addition to the 328d sedan and wagon, 535d sedan and X5 xDrive35d crossover, we now have this, the BMW 740Ld xDrive (not to mention the refreshed 2015 X3 xDrive28d that also makes its debut here in Chicago). As its name - and the photos above - suggest, this means BMW is offering diesel power in its flagship, long-wheelbase 7 Series sedan, set to directly compete with the likes of the excellent Audi A8 TDI.
Under the hood is BMW's familiar 3.0-liter turbocharged diesel inline-six, delivering 255 horsepower and 413 pound-feet of torque, all of which is sent to the road via the company's xDrive all-wheel-drive system and ZF eight-speed automatic transmission. That torque thrust is available straight away from 1,500 rpm, and BMW says the 740Ld xDrive will sprint to 60 miles per hour in a very respectable 6.1 seconds. Official fuel economy estimates haven't been released yet, but we expect the car to net highway fuel economy ratings in the mid-30 range.
The 740Ld xDrive arrives in BMW showrooms this spring, priced from $82,500, not including $925 for destination. We're pretty stoked to drive it. But in the meantime, have a look at fresh images of the big sedan live from the Chicago Auto Show, above.

Researchers halfway to cutting carbon fiber costs by 90%

Carbon fiber has been utilized for decades to build racecars, as a means to cut weight while maintaining strength. But until recently, the space-age material has been largely absent from the street on anything but supercars because of the expense to use it. Recently, BMW signaled a major shift in that trend when it starting using carbon fiber reinforced plastic panels on the i3 and i8. This relatively small scale start might be just the beginning; the German company believes that a breakthrough to inexpensively manufacture the lightweight stuff is just on the horizon.
MAI Carbon Cluster Management GmbH counts BMW, Audi, Airbus, the German government and many other organizations as supporters, and it's researching how to make carbon fiber cheaper to produce, according to Automotive News Europe. The company thinks it can reduce costs by 90 percent in the near future. "We've certainly reached a halfway point on our cost-cutting target for suitable carbon-fiber parts," said project head Klaus Drechsler to Automotive News Europe.
Unfortunately, it isn't entirely clear just what MAI Carbon is doing to make such a huge leap possible. However, a recent post on the company's website talks about a new form a carbon fiber using a thermoplastic matrix that could be cured in less than three minutes. That's compared to about 90 minutes in the traditional process with an autoclave.
