(CNN) When Elon Musk unveiled Tesla's much anticipated Cybertruck Thursday, he showed a video of the all-electric truck winning a tug-of-war against a Ford F-150 in spectacular fashion. As Ford's bestselling pickup was dragged backwards, its wheels spinning, Musk pointed out that the Cybertruck was pulling the Ford uphill.

Musk tweeted out that same video Monday and a Ford executive responded by challenging Tesla to a real "apples to apples" truck test. Elon Musk, in turn, responded "bring it on." But it's far from clear that this is a fight Ford actually wants.

Let's back up a moment to look more closely at what happened here.

Tesla's TSLA After Musk tweeted the truck battle video, a writer for the car blog Motor1 pointed out that the F-150 Cybertruck was pulling was apparently a rear-wheel drive truck -- only the Ford's back wheels can be seen spinning -- and that, alone, made it an unevenly matched fight. The Cybertruck prototype was all-wheel drive and that would give it an advantage because it could pull with all four of its wheels.

The Motor1 post also noted that, from looking at the features on the Ford pickup, it probably had Ford's turbocharged 2.7-liter V6 engine, far from the strongest engine to be had in an F-Series truck. (Tesla has not said what sort of F-150 it chose for this fight.)
