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.

Next BMW M3 sedan to be plug-in hybrid?

BMW has a lot in mind for the next-generation 3 Series and 4 Series cars, and we're hearing about it now even though they're not expected for another three or four years. The sedan is expected to be lighter, wider, with a longer wheelbase and a lower center of gravity. Rumored tech updates include the water injection system debuted in production on the BMW 1 Series, and the 4 Series convertible might go back to a fabric top. Now The Detroit Bureau reports BMW insiders have revealed that the next M3 will get a plug-in hybrid drivetrain. We've heard about plug-in variants in the mix for the G20 3 Series using a small displacement four-cylinder, but not on the M3 and possibly M4. The goal is familiar, according to the "several senior company officials:" to improve the performance while reducing the emissions footprint. Apparently, the power unit being worked on uses a "similar engine" to the 425-horsepower, 3.0-liter inline six employed at the moment, with power sent to the rear wheels. Electric assistance would come from a KERS-like unit that would also - and only - send power to the rear wheels. Torque is said to go up at least 73 pound-feet from the 406 lb-ft available currently, and all-electric range might be as much as 20 miles. Plenty of carbon fiber will help offset the weight of the lithium-ion batteries. Despite company obfuscations, we know BMW is working on a hybrid powertrain for a vehicle rumored to be called either i5 or i7, and would use one or two electric motors to drive the front wheels while the traditional ICE drives the rear wheels. This potential M3 and M4 powertrain would be an offshoot of that engineering. Automobile speculates there will be electric turbochargers and a horsepower number around 500. Related Video:

2014 BMW 328d rated at 32/45 mpg

BMW still hasn't released official fuel economy numbers for its diesel-powered 2014 328d, but now, those mileage ratings have been posted on the EPA's FuelEconomy.gov website. As expected, the 328d is quite an efficient little machine, with the rear-wheel-drive sedan good for 32 miles per gallon in the city and 45 mpg highway. That even bests the 30/42 mpg of the smaller Volkswagen Jetta TDI.
The last time BMW offered a diesel 3 Series in our market, it was the six-cylinder 335d, which - while mighty quick and excellent to drive - was only offered as a rear-wheel-drive sedan and was rated at 23 mpg city and 36 mpg highway. For 2014, BMW will offer the 328d with optional xDrive all-wheel drive, though that reduces the fuel economy numbers to 31/43 mpg. Beyond that, the BMW will even sell you a 328d xDrive wagon, which nets the same 31/43 mpg rating, according to FuelEconomy.gov.
Look for the 2014 BMW 328d to hit dealerships this fall, and when it launches, it will be the only diesel offering in its class (until the next Mercedes-Benz C-Class arrives, anyway). Lexus and Infiniti will offer hybrid versions of the IS and Q50, respectively, but we've always had a taste for torque, and the 328d's 2.0-liter engine with 180 horsepower and 280 pound-feet of twist shouldn't disappoint.
