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 broadens engine bolt recall to nearly half-million cars worldwide

Almost one month ago, we reported on a BMW investigation into a potentially defective bolt that lived in the company's VANOS variable valve timing system. At that point, the potential recall was seemingly limited to Chinese-market cars; the company was filing a recall application with Chinese officials.
Today, Bloomberg is reporting that the engine bolt issue has expanded into a recall for several world markets, involving some 489,000 vehicles. BMW was able to verify that report to Autoblog, while also providing a great deal more detail about the issue and vehicles affected.
The recall affects vehicles powered by N55 inline six-cylinder gasoline engines equipped with VANOS and Valvetronic technologies. 1 Series, 3 Series, 5 Series and 5 Series Gran Turismo, X3, X5, X6 and Z4 models from the 2010 to 2012 model years are included, as is the 2012 6 Series.

BMW apparently still undecided about future i project electric vehicles

Coaches like to say that there's no "i" in team. At least one BMW executive is saying the company's not sure if there are any more "i"s in its near future. BMW executive Harald Krueger indicated that the German automaker is holding back on any i-project plans besides the i3 city car and i8 plug-in hybrid sports car until the company gets a better idea of how those models are selling, Reuters says. Bimmer has spent about $2.7 billion on the plug-in sub-brand and says it's taken more than 11,000 orders for the i3 since the model was first shown off at German dealerships last fall. Additionally, BMW has no plans to make the i3 in China (BMW makes versions of its 3- and 5-series sedans there). As we all know, should the brand expand, BMW has already trademarked the "i" badge from i1 through i9. There are a lot of mixed messages on the BMW i project front. For example, early indications are that i3 demand has been higher expected. BMW North America chief Ludwig Willisch indicated earlier this month that US demand for the electric city car, at least for the near future, will likely to outstrip supply. Bimmer dealers in the US will start getting the $41,350 i3 in May. Additionally, fellow BMW executive Jacob Harb said the company was already starting to work on its next EV, to be larger than the i3, though he didn't give many details and was later somewhat refuted by another BMW spokesman.
