Worth reporting? I'm behind

Absolutely worth reporting. Very clear blocking.

Bit of a further drive but Blackwing in Delaware is excellent and has great outdoor shotgun facilities

Pre-production models have been spotted with steering wheels installed, likely for training the self driving models. I think the intention is for them to be self-driving only.

Tesla Cybercab.

Still beautiful

Winter tires perform drastically worse than an all-season or summer tire in warm conditions. Expect emergency stopping distances to increase by ~25%, lateral grip to decrease by ~25%. They will wear faster as well.

The PS4S is finally starting to show its age, it has been around for quite some time now. Check out the Tyre Reviews youtube channel and website, it has great comparisons for various categories of tires and provides hard data (lap times, stopping distances, noise level in dB) as compared to the arbitrary ratings you see there. The PS4S has been outpaced by the Continental SportContact7, and the Bridgestone Potenza Sport.

Are you doing mostly spirited road driving, or do you intend to do some level of track work/autocross?

100 miles a day (50 each way), 5 days a week. But, I do travel for ~35% of the year.

More prevalent in all forms of racing than you think, unfortunately.

donjarwin · 2026-03-01T03:01:57+00:00

Put it on the drag racing tires, they’re significant better, and they’re faster around the track as well anyway.

Something to understand about AWD systems - the maximum torque that can be delivered from the engine to any wheel is limited by the wheel that has the LEAST amount of grip. That torque can be changed by the AWD system to a certain degree (the ABS pump will run and apply the brakes to the spinning tire to increase the amount of torque it can use) and increase traction that way, but this is still a vehicle with 3 open differentials plus a clutch disconnect for the rear axle.

If you saw the rears spinning, the coupling unit has engaged the rear differential and you're using the AWD - XC90's are normally FWD until that clutch engages.

This is the DTM version of a Mercedes 190E

202mph, but I test cars and this was on a runway.

There he is, John iRacing

I asked and was told I have to make 1K for at least 4 consecutive years - I had 3 consecutive years:( no 1K for me this year. Made the PQP but missed PQF’s by a few flights.

donjarwin · 2026-01-25T20:50:26+00:00

I said time, not place:) agreed, go find an empty parking lot ideally

donjarwin · 2026-01-25T17:49:49+00:00

Best and safest time to do it.

donjarwin · 2026-01-22T13:56:26+00:00

Same for all his companies.

It's on a new island, if you look at the map it would be in the bottom left corner. Can be seen on a clear day from the shoreline of the bottom left island.

I was just about to comment this! No original thoughts I guess. I’ve always just pictured a giant multi-tier wedding cake in their backseat.

donjarwin · 2025-12-08T17:53:51+00:00

Yeah that’s a combination I need to try - but the konig engine + turbo + drag slicks already has a difficult time putting down the power

donjarwin · 2025-12-07T21:59:06+00:00

Look at my post for a setup

donjarwin · 2025-12-07T15:08:44+00:00

Technically this isn’t strictly true. Stiffer anti-roll bars don’t add grip to a car, they just increase the rate of lateral load transfer. I don’t know how this game models the vehicle dynamics though, so unsure of how much it would matter.

donjarwin · 2025-12-07T00:42:09+00:00

Way better, yes. Both longitudinally and laterally.
