In one of the crucial genius experiments, a Tesla Mannequin Three was charged by being towed utilizing a Ford F-150 Raptor and the outcomes will make you query what you understand about thermodynamics.
On a critical notice, the experiment didn’t break any legal guidelines of Physics, in truth, it proves simply how important regenerative braking and aerodynamics are in rising effectivity of the Tesla Mannequin 3.
The experiment was carried out by Jason Fenske, who runs a preferred YouTube channel known as Engineering Explained. In his experiment, he answered a variety of questions together with “what’s extra environment friendly? To drive a Ford F-150 Raptor alone or tow a Tesla Mannequin Three behind it and recharge it after which drive it?”
Right here’s how issues performed out.
Tesla Mannequin Three Vs Ford F-150 Raptor Effectivity Take a look at
Within the first spherical of testing, Jason and his associates tried to search out the reply to 2 predominant questions, “Are you able to recharge a Tesla by towing it?” and which is extra environment friendly: “To drive a Raptor from level A to level B?” or “Use that raptor to cost a Tesla and take that Tesla to wherever you’re going?”
Jason tied the Tesla Mannequin Three behind the Ford F-150 Raptor and his pal drove the truck round for a single lap. At the beginning of the lap, the Tesla Mannequin was at 62% cost and simply after touring a number of meters the Mannequin Three gained round 740 Wh/km of cost.
By the point the lap ended, the Tesla Mannequin Three had gained about 1,019 Wh/km, or round 1 kW of power utilizing regenerative braking with an extra 2% of electrical battery cost at 64%. The Raptor was driving at a relentless velocity of 30km/h whereas towing the automotive.
Jason then drove the recharged Mannequin Three across the similar monitor. The electrical automotive accomplished the lap with round 165 Wh/km of remanent cost. Additionally, understand that Jason drove the automotive fairly aggressively across the monitor and nonetheless managed to avoid wasting electrical cost on the finish of the lap.
Now, at first look, it won’t be clear how power is being transformed thrice, from gas in Raptor to regen in Tesla and from its battery to its electrical motor.
“Once you’re pulling it’s (the Mannequin 3) it’s mainly braking actually onerous, so that you’re pulling one thing that’s taking the kinetic power of what velocity the automotive is at consistently,” explains Jason.
He then carried out one other check to search out out which automobile returned most miles on a single gallon of gas and by which approach. Is it extra environment friendly for the Raptor to journey alone on one gallon of gas or tow a Tesla Mannequin Three and recharge it as properly?
By itself, whereas driving across the monitor, the Ford F-150 raptor delivered a gas effectivity of 22 liters per 100 km or 10.eight mpg. Whereas Tesla Mannequin Three took 193 Wh/km, which is equal to 2.2 liters per 100 km or 108.5 mpg.
Whereas towing the Tesla Mannequin Three the raptor gave a gas effectivity of 69 litre/100 km or 3.four miles per gallon. Nevertheless, through the means of being towed, the Tesla Mannequin Three gained sufficient power to journey 18.1 miles.
“So 1 gallon of gas in a Raptor will will let you recharge your Tesla for 18.1 miles. So it’s extra environment friendly to tow the Raptor with the Tesla than to drive the Raptor by itself.”
Which Is Extra Environment friendly?
So to recap, the Ford Raptor travels round 10.eight miles/gallon of gas when driving by itself. Tie a Tesla Mannequin Three behind it and its gas effectivity is diminished to simply 3.four miles per gallon, nevertheless it recharges the Tesla to drive an extra 18.1 miles.
Due to this fact the entire distance traveled equals 21.5 miles.
It’s one hell of an experiment and the outcomes may baffle some puny individual’s mind as they did it to me. Nevertheless, Jason defined that whereas towing Tesla the Ford Raptor is dealing with an enormous quantity of drag as it’s much less aerodynamic and weighs much more than the electrical automotive.
Mannequin 3, alternatively, could be very aerodynamic and due to this fact delivers excessive gas effectivity after being recharged.
I hope you’re nonetheless with me in spite of everything these calculations. And if I did a poor job in explaining this stunning experiment, watch Jason’s video above to get a greater concept about issues.
