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 i5 could get Toyota-sourced hydrogen power

It's starting to feel like the automotive landscape is right on the cusp of a boom in hydrogen-fueled vehicles. After all, the Toyota FCV is nearly ready, Volkswagen is readying a fuel cell concept for this week's Los Angeles Auto Show and Hyundai already sells its Tucson Fuel Cell. The next big name to add to that list might be BMW, as the company's co-development deal with Toyota starts to bear fruit.
According to Autocar, BMW may use a version of the fuel cell system from the Toyota FCV in the future i5. As part of its eco-oriented i sub-brand, the i5 is expected to be a stretched version of the i3 (pictured above) with extra rear legroom and cargo space. It's unclear at the moment whether a battery-powered pure electric powertrain will also be available. If accurate, then the rumor could give the Bavarian brand a counterattack against Mercedes-Benz' planned fuel cell vehicle in 2017.
BMW and Toyota first signed the memorandum of understanding to co-develop fuel cells, lightweight technology and a sports car back in 2012, and they made the arrangement official in late 2013. So far, few details on the progress of the work have been disclosed, but the performance model has been rumored to use a front-engine, all-wheel drive layout with supercapacitors.

BMW looking to fix i3 acceleration problem uncovered by Consumer Reports

The BMW i3 has been hailed in some quarters as the future of electric mobility, what with its innovative carbon-fiber-reinforced plastic body and commitment to sustainable materials wherever possible. The modernist little hatch is even available with a 650cc two-cylinder gas engine with 34 horsepower to act as a range-extender for those who want it. However, that optional engine might have a drawback - at least for the moment.
Consumer Reports brought the problem to light when one of its drivers was behind the wheel of an i3 using the range-extender. When the driver attempted to pass another vehicle on a rolling, two-lane road, the BMW suddenly had no power to accelerate - a scary situation. CR started examining the car and found something pretty shocking: After driving at a constant speed for a while without any regenerative braking in range-extended mode, acceleration to 60 miles per hour plummeted from about 9 seconds normally to a staggering 27 to 40 seconds in their testing.
A BMW spokesperson told CR that it knows about the problem and has a fix coming next spring that also works on current models. The upgrade includes a state of charge indicator, a warning about loss of power and uses the car's navigation to boost the battery before driving on rolling terrain. It is not clear if the severe power deficiency will also eventually result in a recall.
