With the release of Tesla’s (TSLA) Cybertruck on Nov. 21, Elon Musk posted a video to Twitter showing the vehicle in a tug-of-war match with Ford’s (F) F-150 pickup truck. While some speculation about the validity of the test circulated, Ford responded to the Tesla CEO in a tongue-in-cheek gesture that may put the two electric truck makers in a head-to-head battle.

In a tweet to Musk from Sundeep Madra, vice president of Ford X, he challenged the Cybertruck to an “apples to apples test” with its Ford F-150. The challenge came after the video showed the Cybertruck winning the tug-of-war contest against Ford’s popular F-150 pickup truck.

Quick criticism of the video came as viewers wondered about the specifications of the F-150. Many speculated that it was a base model with rear-wheel drive and not a top-end model that would more fairly compete against the Cybertruck, Motor 1 reported.

Encouraged by the challenge to a fair battle from Madra, Musk responded on Twitter, “Bring it on.”

Ford has announced that it is bringing its own all-electric F-150 pickup truck to market, which is expected to arrive in 2021. The automaker has teased the power of the truck, showing it pulling 1 million pounds of train cars.

Shares of Tesla stock were down 1.55% as of 1:31 p.m. EST on Tuesday while shares of Ford stock were down 0.39% at the same time.
