BMW M3 and M4 will rock 430 hp from twin-turbo six with standard manual [w/video]

We're not sure which spec we're most intrigued by for the new BMW M3 and M4: the twin-turbo six-cylinder with 430 horsepower and "far beyond" 369 pound-feet of torque, the 3,300-pound curb weight or the standard six-speed manual transmission with automatic throttle blipping on downshifts. That engine is fitted with both Valvetronic and Double-Vanos, twin-wire arc-spray coating in the cylinders instead of liners to save weight, a track-ready cooling system with additional radiators, a forged crankshaft, dry-sump lubrication and a magnesium oil sump. BMW says its "high revving concept" has a redline beyond 7,500 rpm.
In the M4, it will be pulling a coupe with "a weight of just under 1,500 kilograms," which is 3,300 pounds to you and me. That number is said to include no driver and 90 percent fuel, but we're still waiting on the exact number and specs. BMW says it's "around 80 kilograms lighter than a comparably equipped predecessor model," putting the power-to-weight ratio at something like 7.68 pounds per horsepower at the same time as it helps reduce fuel consumption by 25 percent. The use of carbon fiber reinforced plastics (CFRP) for the roof, drive shaft (with no center bearing), trunk and front strut brace, and forged aluminum for suspension components, have aided in the weight loss. This time around, the sedan - the M3 - will also get a CFRP roof.
The default option will be a six-speed manual.

2015 BMW M3 is fast for the family man

BMW finally brought its four-door M3 into the public view, showing the new sedan off at the 2014 Detroit Auto Show. The new M3 represents BMW's return to small, wildly fast four-door sedans after a several year absence following the discontinuation of the E90 M3 Sedan way back in 2011.
The M3 enjoys the same 425-horsepower, 3.0-liter six-cylinder used in the M4, with 406 pound-feet of torque and the owner's choice of either an old-fashioned six-speed manual or a seven-speed M dual-clutch transmission. All told, the new powertrain should scoot the four-door M to 60 in a mere 3.9 seconds (with the M DCT).
We've got a full gallery of live images of the all-new M3 up above, and we've included the original stock gallery down below. Feel free to peruse either, and then let us know what you think by sounding off down in Comments.

BMW and Mini getting GoPro integration

The small, high-quality and relatively inexpensive GoPro camera has been revolutionary for Internet video, especially of cars. Imagine how much awesomeness and hilarity we would have missed without them. Finding ways to integrate the cams into performance cars is becoming increasingly popular among automakers, as well. For example, the 2015 Chevrolet Corvette has its Performance Data Recorder, and Volkswagen is giving GoPros to early buyers of the 2015 GTI. BMW Group is going straight to the source for its rendition, though, with a new app that allows drivers to control a GoPro from inside of some BMW and Mini vehicles.
In July, owners with 2012 or later models equipped with BMW Apps or Mini Connected can download the new app. There are a few hurdles to jump over, though. Not only do users need a model with the infotainment system, a WiFi-equipped GoPro camera is also required. The app also must be installed on an iPhone connected to the vehicle.
Once all of those stipulations are met, the app can configure and control the GoPro through iDrive and display a nearly live image on the infotainment system. Menus are simplified on-screen but still allow users to select among six camera modes, aim it and start and stop recording. While filming, it shows recording time, battery life and signal strength. While BMW's approach isn't quite as nicely integrated as the Corvette's solution, it's interesting to see automakers working to make filming easier. Scroll down to read the full announcement.
