I'm trying to understand why the XFG seems to oversteer under acceleration at times. My understanding was that throttle would shift the weight to the back and give understeer. I have been told that throttle should balance out the car in front wheel drive, but that doesn't seem to work sometimes?

I tried to make this happen for a replay for this question. It's not an ideal example but I'm just trying to understand what's happening. First corner in file 123, last corner in file 122 Thanks.

You need work on the setup, some people love understeer, other oversteer. Put mix tyres for the rear Work on tyres presure, slow gaz etc...

These behaviours originate from track geometry, really. Last corner is you asking too much out of front tyres: applying both steer and brakes, they run out of grip to supply both of these at the same time, so the car just goes forward. As for the first corner, it's really all track geometry, car front loves to drip there first while rear remains on high level throught whole corner. You can either soften the rear damper (from -0.1 up to -0.6 max) or increase the front damper (from +0.1 up to +1.5 max) if that becomes an issue during the race, it might demolish time in other sectors, but better to have setup in which you're able to finish races and improve rather than hop in to hot waters with alien sets just to score new speedruns to grassalla from race start.

Thanks! I'm usually able to keep it under control, was just trying to understand. I'll try test out a different setup, maybe a stiffer front or a softer rear as you said! Cheers

Normally the default setup of the XF GTI has that behavior similar to a Citroën Saxo due to the "bounce" of the rear axle that, sometimes, threatens to drift.

front wheel drive pulls the car around the corners, as opposed to rear wheel drive pushing the car around.

very simply put, think of a keychain that you drag along a table with your finger. if you yank too hard the tail of the chain will swing around too hard. you can yank enough to not make it swing too wide, but just enough to get you to the exit of the turn at good speed.

Thanks, that makes a lot of sense. Definitely feels like I'm dragging the back of the car around the track sometimes haha.

with the exception of keychain rotating freely around

it's hard to explain but i felt that analogy might be the best. car chassis isn't as flexible as a keychain

with braking you might experience a lot of understeer in fwds, too, best to aim your braking to the straightest place and when you want to cut into apex you can yank the chain

depends a lot on differential settings though. if you got locked diff then you will certainly experience this. might be able to configure it on preference but locked diff usually is the fastest setting so it is better to adapt than to circumvent through settings.
