BMW preparing new M4 GTS with water injection

Last month, BMW revealed a new safety car for the MotoGP series. Only instead of just taking one of its production models and giving it some flashing lights, special livery and emergency equipment, the Bavarian automaker used the specially equipped M4 to showcase a new water injection system. And now word has it that the tech is being worked into a new M4 GTS. The system sprays water into the combustion chamber in order to lower the temperature of the air and increase the engine's efficiency, thus allowing it to produce more power without overheating, and relying less on ambient temperatures. It does require refilling a 1.3-gallon water tank in the trunk, though. According to Car and Driver, it's that same system that BMW will be installing in the new M4 GTS, taking the place of previous M3 GTS specials. If precedent is anything to go by, the M4 GTS will also be stripped of excess weight and feature a tighter suspension, stickier tires and more, in order to make BMW's muscle coupe even more hardcore and focused for the track. We could be looking at a debut as early as Pebble Beach in August.

BMW increases i3 price by $1,075 for 2015

The BMW i3 did well in its first year on the market, selling 6,02 units in the US and 16,052 units worldwide. For 2015, it gets total price increase of $1,075, partially reflecting new standard equipment that was formerly an option and a bump in its destination cost. The 2014 starting price of $41,350 becomes $42,400 for 2015, an extra $1,050, and the destination increase of $25 to $950 makes the out-the-door price $43,350. The range-extended model goes up by the same amount, from $45,200 last year to $46,250 this year. After destination, it's $47,200 out the door. For 2015, DC Fast Charging is included, no longer a $700 option, thanks to the expansion of the fast-charging network through a collaboration between BMW, Volkswagen and Chargepoint. Beyond that, satellite radio and heated seats migrate to the standard features list. We have a feeling none of this will hurt the plug-in car's sales momentum this year.

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.
