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 i3 REx rated at 117 MPGe, 39 mpg with 72-mile EV range

The numbers haven't made their digital way to the EPA's website yet, but we can now confirm that the BMW i3 with range extender will be officially rated at a combined 117 MPGe with 39 mpg once the battery runs out. That puts the amazing little city car just ahead of the pure-electric Fiat 500e (116 MPGE, combined) and behind the Honda Fit EV (118) and the Chevy Spark EV (119). In the plug-in hybrid category, it's at the top of the class, beating out the Honda Accord PHEV, which is rated at 115 MPGe but is also a much bigger vehicle. The i3 REx also has an official all-electric range of 72 miles and can go another 78 on gas (for a total of 150). When it's not carrying around the extra fuel tank and engine, the all-electric i3 gets 124 MPGe (combined), which is the currently the highest in the US. The i3 EV also has an all-electric range of 81 miles. BMW expects to deliver the first i3 REx in the US this week and delivered the first all-electric version earlier this month. There was a bit of a hold-up on the range-extender version thanks to a delay with getting these EPA numbers. Now that all the bureaucratic boxes have been checked, it's off to customer driveways they go.

2014 BMW Z4 sDrive35is

The BMW Z3/Z4 roadster has never really had a widespread following because it has either been too humble and small a roadster (albeit with some fun and very low-volume M editions) or it has been - in this E89 generation - too casual an image leader with no racier aspirations. The current 480-hp Z4 GTEs don't count, since they are as stock a Z4 as today's Pamela Anderson is the same blonde actress we knew as Heidi on Home Improvement. You know, sort of like those ever-so-slightly modified Toyota Camry coupes competing in NASCAR.
The ultimate highpoint for the BMW Z roadster franchise was at the very start of its life in the mid-90s, in the James Bond film GoldenEye with Pierce Brosnan. The Stinger missiles that Q's team installed behind the Z3's headlights were never fired, and BMW never even offered this self-defense package as an option. Yet another case of the ol' bait and switch.
And in all these subsequent years of Z3s and Z4s strutting their long-hooded stuff, the little sporting Bimmer could really have used a live Stinger missile or two to spice things up. The current Z4 exists, it is pretty dang sexy, and BMW seems content to let it linger there. We just drove the new midlife version of the roadster near BMW headquarters in Munich, and it served to reinforce our feelings.
