You seem to insist in some idiotic points, totally useless to OP.Oldie wrote: ↑Sat Nov 20, 2021 5:31 pm Am not and never have been and don't care a hoot anyway - simply responding to points raised i.e. blastpipe hadn't heard of energy efficiency of brakes, so explained the theory - however, having driven many many cars the XC40 is a first for me to have a reverse logic to brake wear - i.e. rear's wearing out before the fronts - don't care why, don't matter why - they just do - and seems expensive to replace too - oh, and in the world of thermoelectric devices seems you only need nano-semiconductors to convert, and guess they would be very small???
As OP mentioned he has a T3, so no re-gen there.
If Volvo indeed uses KERS in the true sense ie capturing heat, converting and storing, i'm sure they'd have made a point of explaining that. And that would be at least 35-40 kgs IF they used top-of-the-range tech such as in F1 cars.
Regardless, it wouldn't apply to OP's car.
Besides Hill Start, handbrake etc, you'll surely notice the car doesn't lean forward very much when braking, so perhaps more pressure is applied to the rear to keep the car as level as possible, or as comfortable as possible going by their Comfort driving mode.
So yeah, maybe learn when to stop and accept that you're wrong, or learn to read the question properly
