Answer: A Boeing 787.
A Tesla Model X now holds the Guinness World Record for the “heaviest tow by an electric production passenger vehicle.” The feat was completed last month at Melbourne Airport in Australia. The all-electric SUV towed the aircraft, Australia-based Qantas Airlines’ new Boeing 787-9 Dreamliner, almost 1,000 feet down a taxiway. While there were no passengers or cargo aboard the plane, and only a small amount of fuel, it still weighed in at 287,000 pounds. That’s more than 50 times the Model X’s rated tow capacity of about 5,500 pounds.
This is not the first time a Tesla and an airplane have gone head to head. In 2016, a Tesla Model S and a Qantas Boeing 737 raced each other down a runway. According to a Qantas press release, the Qantas-Tesla partnership is exploring ways to reduce the airline’s carbon footprint and “[drive] innovation for our customers and increasing sustainability in the transport industry.”
