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 performance engineering boss wants an M7

Audi has the S8, Mercedes has the S63 AMG and Jaguar has the XJR, but BMW has always held that an M7 wasn't justified, leaving its associated Alpina line to tackle that market with the B7 (pictured). The chief engineer at the M division, however, feels otherwise.
Speaking to Autocar, the BMW M development chief Albert Biermann indicated that he would like to see the M division do a performance version of the 7 Series to compete with the above-mentioned models, but that there are no current plans in place to do so. Neither did he specify what kind of engine it would have, or if it would be badged, for that matter, as an M7 or an M Performance model.
The latter is the approach which the M division is reportedly taking with performance versions of BMW crossovers beyond the X5 M and X6 M, such as the X3 and upcoming X4. The division is also said to be developing a performance-tuned xDrive system to compete with AMG's new all-wheel-drive models, as well as a potential M3 GT to join the new M3 sedan and M4 coupe with a slantback bodystyle.

2015 BMW X4 is a budget X6

We won't argue that crossovers are hugely successful vehicles, with automakers working to provide functional CUVs in a wide range of sizes. But over at BMW, things are just getting out of hand, as evidenced by this new X4 "Sports Activity Coupe" that debuts here at the 2014 New York Auto Show.
BMW is seeing fit to offer vehicles in even the most niche of niches, and the X4 is no exception. Want proof? Have a look at the X4, and the compare it to the X3, the 3 Series Gran Turismo, the 3 Series Sport Wagon, and the 4 Series Gran Coupe. Aside from marginal differences in things like ground clearance and the exact slope of the hatchback, what, exactly, is the difference?
Like the other models we just mentioned, the X4 is powered by either a 2.0-liter turbo-four with 240 horsepower or a more powerful, 3.0-liter turbo-six with 300 horsepower, and unsurprisingly, power is sent to the ground exclusively via the company's xDrive all-wheel-drive system. An eight-speed automatic transmission is the sole gearbox available with either engine. All sounds very familiar, right?
