The latest achievement comes from Tesla and its Model X P100D, an all-electric SUV that managed to tow a Boeing 787-9 Dreamliner from Qantas. By pulling 143 tons, the Model X - which has a 5,000-pound towing capacity - is billed by the Australian airline company as being the new record holder for the heaviest tow accomplished by a production electric passenger vehicle. The record-breaking attempt took place at the Melbourne airport in Australia.
