BMW readying impressive track-focused M Power App

There are a lot of questionable automotive apps that people put on their smartphones these days, but BMW has created what could be one of the most useful and integrated car apps ever. The new M Power App, which will be available this summer only for Apple iPhones, allows BMW owners a whole new way to record their performance on the street or on a track. During the launch of the recent BMW M6 Gran Coupe, BimmerPost was able to get a full demonstration of how this new app works.
Far more involved than the current M Power Meter, the M Power App records data from in-car sensors and acts as a telemetry tool to allow drivers to see how they did on a particular track. Aside from an overlay on a track map showing acceleration and braking applications as well as head-to-head comparisons, the app also shows a line graph of everything from brake and throttle inputs to g-force, fuel mileage and engine speed. A small visual on the screen also shows steering angle, and lap times and speeds can all be stored as well. The data can even be shared with others, whether for bragging rights or instruction purposes.
This app works on any newer BMW equipped with the BMW Apps option, but the phone must be tethered to the car and the data understandably cannot be viewed while driving. Scroll down for the video demonstration recorded recently at Austin's Circuit of the Americas.

2014 BMW 4 Series Coupe officially debuts, priced from $41,425*

Well, that didn't take long. Less than two hours after the first images of the 2014 BMW 4 Series Coupe leaked onto the Internet, we've been given the go-ahead to publish the whole kit and caboodle. And while we won't say we told you so, it looks as though the car's official details are standing true to our earlier predictions.
In other words, BMW will offer the 4 Series in 428i and 435i models, both of which can be had with xDrive all-wheel drive. Just like in the 3 Series, the 428i is powered by a 2.0-liter turbocharged inline four-cylinder engine, good for 240 horsepower and 255 pound-feet of torque, and the 435i gets BMW's turbocharged 3.0-liter inline-six making 300 hp and 300 lb-ft. In three of the four models, both a six-speed manual and eight-speed automatic transmission are available; the 428i xDrive can only be had with the auto 'box. The 428i (with rear-wheel drive, we assume) can hit 60 miles per hour in 5.7 seconds (though BMW doesn't specify with which transmission), and the 435i will do that same sprint in 5.3 seconds with the manual and five seconds flat with the eight-speed auto.
We've already dissected the 4 Series' visuals, but the numbers show just how different it is from the 3 Series sedan. The 4 Coupe is one-tenth of an inch longer overall, while riding on the same 110.6-inch wheelbase, is 0.6 inches wider, and has a roofline that's a full 2.7 inches closer to the ground. It looks sleek, incorporating BMW's new design language from the 3 Series with an overall profile that's similar to the larger 6 Series coupe.

2015 BMW M3 Sedan

BMW's all-new M3 Sedan is dynamically nearly identical to its two-door M4 Coupe sibling: a stopwatch reveals that both are sub-four-second cars to 60 miles per hour, a racetrack proves that the mechanical twins are equally as adept on a road course and a full afternoon of driving on public roads demonstrates that each possesses talented everyday adaptability.
Yet after driving both BMW models back-to-back over two full days in Portugal, it's clear there are a few noticeable differences, both objective and subjective, that don't require instrument testing to reveal. All it takes is a few hours behind the wheel of both cars to conclude that one is slightly more agile, and the other a bit more twitchy. One has better outward visibility, while its counterpart is unquestionably more convenient.
It is the little things - subtleties attained through seat-of-the-pants observations - that eventually allow me to choose a favorite.
