No, there’s a starter / alternator / generator bolted to the front of the engine. The fan is bolted to the back of the body.

“ Finally, a V-max mode works just like Streamline mode, but takes top speed over consumption and gives the car a 30bhp boost using the 48V starter motor.”
So 30hp boost for some Vmax running means a fairly chunky battery?

He explained in Harry’s video. They’ve developed their own power pack with a 12v battery, a 48v battery, a cooling system and something to do with running the aircon that somehow only weighs 12 kilos.

On reflection, I am not sure he's thought through every scenario.
Imagine you take delivery of your new T50. (Why did you order it with the drivers seat in purple Ostrich skin Jimmy? )
You're making progress along a country road, revelling in the available grip, when you come across a section where Farmer Bill has been dragging his manure truck, and the contents have spilled onto the road...... well.... I don’t need to spell out what's going to happen next do I ?....
It's filtered, so not much really.
If the filter is after the fan - my joke still works.
But I suspect it is ahead of the fan.
So you have ruined my joke.
Come 2 think of it - These filters are going to need replacing pretty regularly I would think....

Apparently they don't expect it to pick much up due to the way the air is being directed, so perhaps not as much as you'd think.
That said, I suspect the test mules will prove that one right or wrong....

I'm struggling to understand how the fan draws 8.5KW ?
40cm fan spinning at 7krpm. 8.5kw probably isn’t the steady-state power requirement at this speed, but the power needed to quickly accelerate it to this speed in order that it can actually respond quickly enough as part of the active aero system?
At a guess when producing that amount of air supply/ suction it’ll be under quite a bit of load.

It's gonna turn the boundary layer along the diffuser to shit?

That filter shall from now forth be know as the shit filter.

Sort of defeats the point of the active aero though, which is specifically to avoid having a massive wing.
Fucking felt tip fairies!

Well I’ve had a look at the Le Mans Hypercar regulations and the fan would be banned.
“ 3.4.1 General
Only one bodywork may be homologated.
Only one bodywork adjustable aerodynamic device (such as a wing, flap...) may be used. Whatever the position of this device, the car must fullfill the aerodynamic criteria defined in the Appendixes to these Regulations at all times. Movable and/or deformable bodywork parts/elements are forbidden when the car is in motion.
Any system operated automatically and/or controlled by the driver to modify any airflow when the car is in motion is forbidden, unless explicitly authorized by the present regulations.”
I admire the ‘no aero add ons’ philosophy, it all goes to pot when there’s a massive weird looking fan glued to the back though, hardly subtle aero is it
Personally I think it would look miles better with a little splitter at the front like the lm rendering.

Solution: have it controlled by another team member via remote control.

yep, the strange little overbite front end needs a lower part to finish it.
