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 vs. Lexus RC F in Head 2 Head sports coupe showdown

It's the showdown everyone's been looking forward to, the East versus West grudge match of the year. We're talking, of course, about the BMW M4 versus the Lexus RC F.
Although BMW uses a twin-turbo straight-six and the Lexus uses a free-breathing V8, the two are pretty closely matched on paper: a luxury coupe with over 400 horsepower channeled to the rear wheels.
The BMW has been doing these cars for longer, and the M4 boasts a higher power-to-weight ratio. But then the RC F has more power - and without forced induction to break up the rev range. So which is the better luxury muscle coupe? Watch the latest episode of Motor Trend Head 2 Head to find out.

BMW wheels out single-cylinder G 310 R motorcycle

BMW makes a lot of motorcycles, including cruisers, enduros, off-roaders, sport bikes, and scooters. The one thing it hasn't done is a single-cylinder motorcycle with less than half a liter of displacement. But that all changes with the arrival of the G 310 R. Previewed by the Concept Stunt G 310 revealed last month in Brazil, the new G 310 R is BMW Motorrad's first sport bike with an engine smaller than 500cc. Though developed in Germany, the G 310 R is built in India around a new liquid-cooled single-cylinder engine displacing just 313 cc. That tiny cylinder does boast four valves, along with dual overhead camshafts and electronic fuel injection. It makes 34 horsepower and 21 pound-feet of torque. The engine is nestled into a compact tubular steel frame. It features a single headlamp up front, a molded fuel tank, 17-inch wheels, disc brakes with ABS, and aggressive styling. It all weighs just 350 pounds, with a seat that's less than 31 inches off the ground. Along with the G 310 R, BMW also revealed an electric motorcycle concept based on the S 1000 RR. That one you can check out on Autoblog Green. For a closer look at the G 310 R, you'll want to peruse the extensive image gallery above, and for further details, the press release below. BMW Motorrad G 310 R The new BMW G 310 R – the first BMW roadster under 500 cc. One cylinder, low weight, powerful dynamic performance – the BMW G 310 R embodies the pure essence of a BMW roadster: it has neither too little nor too much of anything. Pragmatic in the best sense of the word, it offers precisely what is needed – for dynamic performance and comfort, both in town and out in the country. The BMW G 310 R takes these essential qualities into a capacity segment that is new to BMW Motorrad. As a genuine BMW roadster it masters a range of disciplines: it is just as happy winding its way nimbly and flexibly through the narrow streets of a city as it is travelling supremely and powerfully along country roads. And thanks to its exceptionally low level of fuel consumption and a relaxed, comfortable seating position, it offers the welcome capability of being able to cover a long distance at a time. At home on the roads of the world. Newly conceived from scratch, the G 310 R represents everything BMW Motorrad stands for: innovation, quality and of course many years of carefree partnership with its owner.
