    Like when he said that the CyberTruck beat a Porche Porsche 911 in a quarter mile whilst towing a Porche Porsche 911, but Engineering Explained did the math and called BS. Then backed up the math by actually doing the quarter mile to prove it.

        I read that a few times…is he saying Porsches break down a lot so ya the truck would win. But then I noticed the spellings. So ya a cyber truck would beat a Porche, they’re cheap knock offs of Porsches

          The entire gimmick was “cybertruck is faster loaded with an entire car and towing it, than the car itself”. They didn’t mention they didn’t go for the entire 1/4 mile. They didn’t mention they cherrypicked the slowest Porsche there is. They didn’t mention they lightened the trailer etc. It was 100% made in their favour, yet they still lost.

            IMO a lightened trailer is fair. It’s really all about power to weight ratio. If a cyber truck could tow a car faster than that car can drive itself, then it means the power to weight ratio is that much higher. Torque also plays a role. They’d have to use a negative weight trailer for it’s weight to change that.

            Guessing they ran the numbers and realized the instant torque of the electric motor would give them an edge at the very beginning, based on the “didn’t go the entire 1/4 mile” bit, which just means it takes less than 1/4 mile to make up for the higher torque in that particular scenario.

            Also the skill of the drivers would play a role unless they set up an automated system (and tuned it right for both vehicles).

              No, the marketing was “a tesla towing a porsche is faster on a 1/4 mile than the porsche”. And then they only tested it up to 1/8th, and “extrapolated” that it would win 1/4. Which it didn’t. It simply was false advertising, even with everything going “their way”.

                Yeah, I don’t disagree with the way you put it there, the only part I disagree with in your comment above is that using a lightweight trailer should be considered a part of the cheating.

                  Why isn’t it part of cheating? You wouldn’t be able to use that trailer on public roads. It’s not that they used a lightweight trailer, it’s that they took an already barebones trailer and then cut and hacked away at it to make it lighter.

                    Because being able to accelerate just the combined mass of the two vehicles faster than the other can accelerate its own mass alone would still be impressive when that other vehicle is a high performance one.

      Silly human. You used earthling mathematics. On Mars (where Lonnie is from), physics works a different way. See? Lonnie is the genius all his sycophants say he is.
