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 E9 3.0L CSL Batmobile is an awesome retro racer

When BMW released pictures of its 3.0 CSL Hommage earlier this year and then brought a period-livery racing example to Pebble Beach, this is the car it was looking at. The BMW E9 New Six CS came before BMW Motorsport and BMW M cars existed, and well before the tagline "The ultimate driving machine," but it paved the way for all of them. Built as a road-going coupe from 1968 to 1975, 1,265 units out of a total production run of 30,546 units were homologated for the European Touring Car Championship. Fitted with the final specification aero package in 1973 and powered by a 3.003-liter inline six-cylinder with a base rating of 200 horsepower, it proved such an able racer that it won the overall ETCC trophy six times - four of those after its road car donor had ceased production, and a bunch of other races like a class win at Le Mans. Clean samples go for huge money. That aero kit earned it the nickname "Batmobile," and Car Throttle drove a left-hand-drive version in the UK (BMW did build 500 right-hand-drive models, though). This is less a car review and more a dream drive, the host letting us know right off that the 3.0 CSL is the one car he's wanted to drive more than any other. He also finds that the Coupe Sport Leicht had a stop/start system... of the temperamental kind. Check it out in the video above. Related Video:

Alpina B4 coupe will be your subtle M4

We're big fans of Alpina here at Autoblog - the BMW tuner has created some seriously delicious products in the past, and recently tuned the diesel-powered 3 Series wagon to create the D3 Bi-Turbo. What we like most about Alpina is how the cars only look subtly more aggressive than stock, yet they pack a real wallop under the hood.
Take this B4 Coupe, recently spotted testing at the Nürburgring. It looks pretty tame compared to the normal 435i, the only visual additions being the Alpina-standard 21-spoke wheels, modified front lip and rear wing spoiler. But under the hood, Alpina is reportedly working on a tuned, twin-turbo straight-six that produces something like 410 horsepower. That means the B4 should be good for a 0-62 time of 4.2 seconds, with a top speed around 190 mph. Rear-wheel drive will be standard, though our spies suggest that Alpina could also use all-wheel drive here in the B4.
We have no doubt that the next BMW M4 will be super hot, but for those seeking a bit more stealth and exclusivity, this Alpina B4 certainly looks the business. Check it out in our gallery above.
