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 unleashes 160-hp S 1000 R streetfighter motorcycle

BMW Motorrad released the S 1000 RR superbike in 2010, but for those who'd like to take it down a (small) notch, the German motorcycle maker introduced the 2014 S 1000 R, a slightly less-ballsy version of the range-topping superbike, at EICMA on Tuesday.
In its transformation from 193-horsepower superbike to 160-hp sportbike, BMW detuned the 999cc inline four-cylinder engine a bit by lowering the redline from 13,000 RPM to 11,000 RPM, where peak power is made. Torque is rated at "approximately" 83 pound-feet (the RR makes 82.5 lb-ft), but more importantly, engineers tweaked the torque delivery in the R's favor by redesigning the cylinder-head ducts, modifying the camshaft profiles and reprogramming the engine management system. The result is seven lb-ft more torque than the RR up to 7,500 RPM. The R's torque peak occurs at 9,250 RPM.
The bike comes standard with ASC (automatic stability control) and "Race" ABS. Riders can choose between two modes, "Road" and "Rain," which adjust ABS and ASC settings to suit dry or wet roads. DTC (dynamic traction control) is available as an option, and with two modes, "Dynamic" and "Dynamic Pro," the system optimizes traction and helps riders achieve maximum acceleration.

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.
