The overall cost for the SAE Combo DC Fast Charge option that enables the BMW i3’s owner to fill up its battery to 80 percent in just 20 minutes, or to touch 100 percent in half an hour, remains unspecified. Perhaps when it comes to the Los Angeles Auto Show that is set to happen in November, more details will be shared. The BMWi3 will hit the US market sometime in the second quarter of next year. The Range Extender option would arrive in the form of a 650cc, two-cylinder engine which is capable of churning out 34 horsepower which will more or less double the i3’s 80-to-100 mile electric range, courtesy of a relatively diminutive 2.4-gallon tank.
