High power and instant torque of Tesla Model S P85D causes problems for those who test it on the dyno.

Recently, DragTimes presented video on the how Tesla Model S P85D broke and AWD dyno at 700+ ft-lbs:

“While we had trouble getting our Tesla Model S P85D to stay put on a Mustang Dyno back in January due to it’s massive amounts of instant torque, another Tesla P85D owner ran into similar but more destructive issues when trying to dyno his P85D.  After going full power from a slow roll on an AWD dyno, the instant torque was measured at 700+ ft-lbs before breaking one of the dyno belts.

On a previous run where they gradually applied power they measured 435HP and had the Tesla up to it’s 155 MPH top speed on the dyno.”

Well, it seems it’s time to develop dynos for the upcoming new generation of AWD electric cars with at least 1,000 kW.

Maybe also some dynos that really are AWD vs rolling the front wheels and not measuring them.

Maybe dynos that are used for the vast majority of cars aren’t rated for this amount of torque or horsepower…

This isn’t a real problem. Its a Tesla problem.

That car should really be chained (not strapped) down, btw. Its lucky they didn’t go charging through the wall.

Yeah . . . holy smokes, I would not want to be anywhere near people using a dyno like that. They are quite dangerous and can cause a lot of damage if things go wrong. Which does happen occasionally. You can find youtube videos.

“Toroidion 1MW Concept also would broke the dyno” …broke?

yes broke

Better word is break. Broke implies that it already happened.

The dynamometer didn’t break, one of the internal belts in the dynamometer broke. By the looks of it, this belt was pretty old anyway.

Let’s not over dramatize it.

Besides, you can’t really break a dynamometer because if you did exceed the eddy brake capabilities, it just keeps speeding up until the car reaches maximum speed.

Yah, the darn belt is all frayed and torn at each end. It must have been old and tattered.
