Which is stronger? Which has better traction? Tesla Model S or Mercedes G 500 4×42?
Electric motors are characterized by the fact that they offer high torque at start-up, but then the maximum torque is capped and even begins to decrease at high revs.
By comparison, the heat engine develops maximum torque at higher revs and it stays constant over a wide rev range at turbo engines.
What is the situation in this case? Colleagues from Dobre cars put face to face Tesla Model X and Mercedes G 500 4×42.
This is a kind of battle like Schwarzenegger vs Statham. Tesla has two electric motors one on each axle that develop 670 HP in total. But like Rolls-Royce many years ago, Tesla does not communicate maximum torque. The G 500 4×42 has a 4-liter twin-turbo V8 engine that develops 422 HP/ 5250-5,500 rpm and a maximum torque of 610 Nm/ 2,250-4,750 rpm.
So, the G 500 4×42 maximum torque of 610 Nm is achieved at 2,250 rpm and remains constant on a wide rev range up to 4750 rpm, close to the maximum power revs which is at 5250 rpm.
So, who is stronger? Tug of war between Tesla Model X and Mercedes G 500 4×42.
As expected, at the start, the Tesla Model X tends to be stronger and pull a little the G 500 4×42. But only a little.
This is explained by the fact that the electric motors have very high torque at start, but even so the Tesla Model S only manages to move the colossus Mercedes G 500 4×42 a little.
Instead, after accelerating, the torque of the G 500 4×42 increases and reaches its maximum value. At this moment the traction force of the G 500 4×42 is maximum, especially since the G 500 4×42 also has a reductor and three lock differentials that improve traction under load.
In the end, the winner is clear. Mercedes G 500 4×42 tows the Tesla Model S with all the opposition of the 670HP.
