BMW already considering four cylinders for next M3

The cylinder count in BMW's M3 has fluctuated over the years. The original M3 debuted in 1985 packing a 2.3-liter inline-four, but subsequent models went with sixes until the outgoing generation upped the cylinder count to eight. With its latest model, BMW has dropped back to six cylinders with a pair of turbos taking the place of the extra pistons. But the next M3 sedan and M4 coupe could go back to the model line's roots with a four-cylinder engine.
Speaking with BMW M product manager Carsten Pries at the launch of the latest M3 and M4 in Portugal, our Aussie compatriots at Motoring.com.au report that "you could see a future [M3] powered by a four-cylinder engine." Offsetting the reduction in cylinders, the lighter engine would benefit the vehicle's weight and balance, thus enhancing performance.
We wouldn't expect the next M3 and M4 to lose any power in the process, though: Output in the M3 has only risen over the generations, from 192 horsepower in the four-pot original to 282 hp in the six-cylinder E36, 338 hp in the six-cylinder E46, 414 hp in the V8 E90 and 425 ponies in the new turbocharged six-cylinder F80 model. With that latter model having just debuted, it'll likely be a good six or seven years before the next version comes along, giving BMW plenty of time to settle on an engine - however many cylinders and turbochargers it has. In the meantime, you'll have to forgive us for taking a romp down M3 memory lane in the fresh gallery of images above.

BMW Concept 4 Series Coupe proves that 3-2=4

BMW may be calling this 4 Series Coupe a concept, but take a long, hard look - this will be the car that replaces the 3 Series Coupe in the automaker's lineup. Don't let that number change trip you up. This car will have all the basic elements of what makes a 3 Series coupe so popular, and while this isn't technically the production model (there are still come conceptual elements and we don't have powertrain details), it's pretty much what we can look forward to seeing out on the road very soon. And honestly, the naming strategy isn't that weird (though it's still plenty odd) - BMW will be using even numbers for all its coupes and convertibles moving forward. 1 Series, meet 2 Series. And when a 3 Series loses two doors, it becomes a 4 Series.
Dimensionally, the new 4 Series coupe is 1.7-inches wider, half an inch shorter in overall height, and rides on a 2.0-inch longer wheelbase. It's a really pretty thing, with bold, aggressive body sculpting up front, and a rear deck that's sort of like a downsized version of the larger 6 Series two-door. It's all very handsome, but we'll reserve final judgment until we see the production version with its likely smaller wheels and possibly toned-down visuals.
We don't yet have powertrain details, but we fully expect the 2.0-liter turbocharged four-cylinder and 3.0-liter turbo-six to carry over in 328i 428i and 435i guise. Though remember, other 3.0-liter models in BMW's range use 40i designation, so we could possibly be looking at a 440i Coupe, instead. We won't know until the production car officially bows later this year.

BMW calls in 50,000 motorbikes over fuel pump leak

If you don't often see motorbikes being recalled, it's probably because there's less to go wrong on a motorcycle. But a problem with the fuel pump on a wide array of BMW Motorrad products has prompted the National Highway Traffic Safety Administration to issue a recall for over 50,000 of the Bavarian two-wheelers across America.
The issue revolves around the fuel pump flange on R-model, K-model, S 1000 and HP2 motorcycles built as far back, in some cases, to 2005 and as recent as 2012, depending on the model. The flange was found to be prone to crack and leak fuel, which NHTSA evaluated as a fire risk. As a result, precisely 50,184 such motorbikes are being recalled to have their flanges reinforced or, where necessary, to replace the entire fuel pump. If you're the owner of such a Bimmer bike, expect a call from your dealer sometime next month, but you can read the full notice below.
