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 invests in carbon fiber for use beyond i and M models

The immense amount of resources BMW has poured into its i brand program hasn't stopped, and recent developments indicate it's likely to pay off for BMW and BMW buyers outside the i brand. The i8 has already sold out its first year run, the i3 racked up 10,000 orders before it even went on sale and is already the subject of public discussion about being stretched into an i5, and a new investment in carbon fiber production has the automaker talking about CFRP use in non-i and non-M models.
BMW and SGL Group got together to form SGL Automotive Carbon Fibers (ACF), and the joint venture produces all of the CFRP for the i3 and i8 on two production lines at its plant in Moses Lake, Washington. After already investing $100 million to increase capacity, BMW has announced that another $200 million will add four more production lines, tripling production from 3,000 tons per year to 9,000 tons. When the expansion is complete in 2015, BMW says the Moses Lake facility will be the world's largest carbon fiber plant.
That's a lot of weave and the long view is that it will find its way into core models, with BMW exec Dr. Klaus Draeger saying, "As part of an intelligent mix of materials, we will apply carbon also beyond our BMW i and BMW M models in the future," and be able to do so "at competitive costs and in large quantities."

Jay Leno puts focus on some retro-inspired BMW bikes

Jay Leno puts eight wheels on display this week for Jay Leno's Garage from a quartet of retro-inspired BMW motorcycles. They are the creations of husband and wife team Larry and Carol Romestant, who build each one in their home garage.
Larry is a former aerospace engineer who loves BMW bikes, especially the K models. Now, he's combining his passion with a real talent for fabrication to build his own cycles with his wife. With Larry and Carol the only ones working on these projects, it takes them six to nine months to build each one. In addition to the old-school looks, the motorcycles are supposed to be a bit more user friendly than stock. For example, one of them ditches the standard five-speed gearbox in favor of a six-speed unit to be a little more comfy when cruising at high speeds.
Since there isn't enough time to take all four of them for a ride, Jay picks his favorite to test out on the open road. Scroll down to see which one he chooses.
