BMW X4 M40i caught production-ready

It seems like BMW is pretty committed to this whole X4 thing. Aside from the current xDrive28i and xDrive35i, we've captured a round of spy photos showing what our spy shooters tell us is a more dynamic M40i model.
The higher-performance hunchback follows in the footsteps of BMW's other sub-M cars like the M235i. In fact, much like the high-po 2 Series, the M40i is expected to make use of a 3.0-liter, turbocharged six-cylinder, developing 365 to 375 horsepower.
Aside from that, the rest of the X4 M40i fits the brief of other near-M models, with a more aggressive body kit, larger wheels, firmer suspension and brawnier brakes. Expect some mild tweaks inside, too, including sportier seats and an M-specific steering wheel.

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.

2014 BMW 4 Series Coupe images leak out

Because embargoes were apparently made to be broken, images of the 2014 BMW 4 Series coupe have leaked onto the Internet ahead of the car's official debut thanks to Car Design News' Facebook page. As you'll recall, the 4 Series is the replacement for the outgoing 3 Series coupe, its nomenclature falling in line with the rest of BMW's lineup, where coupes and convertibles will be set apart from their sedan counterparts by one number.
As we can see in the photos, the 4 Series takes a lot of its design cues from the 3 Series on which it is based, but there's a lot more in the way of attractive body sculpting, and this production model stays true to the original 4 Series Coupe Concept that we saw at the Detroit Auto Show earlier this year.
We don't have official details to divulge just yet, but we can discern from the photos that the range-topping coupe will be the 435i model, likely powered by BMW's turbocharged 3.0-liter inline-six from the 335i. There will no doubt be a 428i model with a 2.0-liter turbo-four underhood, and we expect BMW to offer its xDrive all-wheel-drive system on both models. Much like the 3 Series, a variety of trim levels will be on offer, including a top-spec M Sport trim that you can see painted in Estoril Blue here.
