BMW patents strange three-cylinder pushrod engines, perhaps for cruiser motorcycle

For decades BMW's motorcycles were easily identified by the two opposed cylinders sticking out of each side of the bike. While you can still find this layout on some of its products, these days the company also uses a variety of other layouts, depending on the model line. Based on European patents, there might even be a Bimmer in the ranks eventually with an absolutely bizarre-looking W3 configuration. BMW actually has two separate patents on these W3 designs, and both of them have the goal of cramming three cylinders into the space of a traditional V-twin. The first splays the cylinder out into a fan shape with pushrods operating the valves. The description submitted to the World Intellectual Property Organization describes the solution as, "The embodiment according to the invention represents an as of yet unknown type of W-3 reciprocating piston internal combustion engine having cylinder angles which can be largely freely sized." The other solution is more of a modification to the traditional V-twin. Two of the cylinders share a crankpin, but the third has its own and is positioned inside the angle of the V. It's a very odd-looking engine. With BMW's assertion that these designs are meant to fit in place of a traditional V-twin, Jalopnik speculates that they could be for a future cruiser from the company, and that would make sense. While brand offers a line of sport tourers with the K1600 line, it doesn't have something more classic to take on the likes of the Ducati Diavel. Creating such a weird engine would probably grab early interest from riders.

BMW M4 spied in coupe and convertible form

From the sound of it, we'll have to wait until the Detroit Auto Show to see the production version of the BMW M4, but spy shots show the new hi-po BMW testing recently in both coupe and convertible form. Showing a lot more skin than recent spy shots, these M4 prototypes look very similar to the M4 Concept we saw at Pebble Beach.
Carryovers from the concept car include the funky mirrors, bulging hood and the slotted front fascia vents, but the rear fascia seems to be missing the added flair of the concept and, as expected, the carbon fiber front splitter and exhaust tips are also missing from these M4s. Like the current M3 Convertible, the drop-top version of the M4 will utilize a retractable hard top.

BMW M2 to pack 365 hp

The BMW M2 was spied testing several times last summer, but there has been little news about the upcoming entry to the M family as of late. More info is finally leaking out though, and it potentially confirms some past reports, while giving a better idea of what the coupe looks like. We have to take any of these leaks with a grain of salt, but according to a user on the 2addicts forum citing insider sources at BMW headquarters, M2 production begins in November. This person also reiterates that the coupe uses BMW's N55 turbocharged 3.0-liter inline-six. In this tune, it would reportedly make 365 horsepower and 343 pound-feet of torque. Plus, an over-boost system would allegedly push twist by about 25 lb-ft at low revs. At launch, this rumor also suggests that BMW might keep the M2's color palette limited to just four choices: Alpine White, Black Sapphire Metallic, Long Beach Blue Metallic and Mineral Grey Metallic. Inside, there're purportedly even fewer hues with the only one being black with blue stitching. Assuming these numbers are accurate, the M2 seems to represent a decent upgrade over the already capable M235i. It also uses a version of the N55 but a version making 320 hp and 330 lb-ft. In addition to the extra grunt, previous spy shots show the M with a front fascia akin to the M3/M4.
