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.

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.

2013 BMW R1200GS and HP4 duel at Circuito de Almeria

The 2013 BMW HP4 is the track-ready version of the manufacturer's already mighty S1000RR, which puts the bike at the very tip top of the two-wheeled BMW food chain. The R1200GS, meanwhile, is intended to be a somewhat more utilitarian machine. Capable of conveying both rider and gear over vast distances and uncertain terrain, the big-boy GS is the Swiss army knife to the HP4's rapier. Or at least that's what we've always been led to believe. BMW recently rolled out some footage during a press launch that showed the R1200GS is actually no slouch when it comes time to sling around a road course.
The company threw both bikes on Spain's Circuito de Almeria for a little sparring match, and miraculously, the HP4 didn't just up and walk away from the R1200GS. From from it. Instead, the two stay tightly matched through most of the course before something surprising happens. We won't spoil the ending for you. Is it possible the rider on the HP4 still had some in reserve? Sure, but from the sound and look of things, neither bike was giving an inch. Check out all the video action below for yourself.
