Tesla has dropped hints that it's ready to extend the range of its electric cars (there was an allusion to a "P100D" hidden in firmware), but it now looks like that long-distance technology is getting closer to fruition. Dutch regulators have approved 100D and P100D versions of both the Model S and Model X, hinting that a 100kWh power pack might soon hit the streets. If the listings are accurate, the Model S would get a whopping 380 miles on a charge -- no mean feat when the 90D can 'only' manage 294 miles. The Model X would likely have a shorter range given that the existing SUV officially tops out at 257 miles, but it's reasonable to say that you'd get over 300 miles on a charge.
