A Closer Look At The Nissan LMP1's Incomprehensible Rear Suspension

Illustration for article titled A Closer Look At The Nissan LMP1s Incomprehensible Rear Suspension

The Nissan GT-R LM NISMO LMP1 car is front-wheel drive. Except when it is sending power to the rear wheels in an utterly incomprehensible setup that may or may not resemble a Unimog.


Here is a better picture of the rear wheel packaging, shot while the car tests at Sebring. The reason for everything looking so impossibly compact is because the car uses flow-through aerodynamics. There are huge air tunnels that run the length of the car and take up the space where rear suspension and rear driveshafts go.

We should be seeing some kind of step-down gearing system for the rear electrical power and we should be seeing the tiny little spring, damper, and wishbones as well.


What do you notice in this picture below, in ultra-high res?

Very interesting arrangement — the near lower piece looks like it's set up purely to carry the vertical load through the coilover, via that turnbuckle/threaded drop link which goes right up to the middle of the upright. The (very short) wishbones are the black pieces top and bottom in the background. I can't tell if there is a toe link between the coilover arm and the lower wishbone or what.

I've never seen a setup like this with a turnbuckle drop link from the upright (for ride height adjustment I guess) down to a lower link, with such a big buckling load on the bottom arm — I guess they couldn't get the lower coilover mount any further outboard because of clearance with the drop link? There doesn't appear to be an anti roll bar unless something's fitted on the front side.

For one thing it's very compact, and for another with the rear bodywork off all of the knobs for damper and ride height adjustment are right there for easy access. Also note how teeny tiny the rear brake disc is.
