Just realised fuel won't be a factor next week. Ran the 962. Alone it tops out at 361-363km/h. With a tow(behind an AI Jag), 371-372km/h.
787B:
No tow - 365km/h
Tow - 373km/h
XJR-9:
No tow - 363km/h
Tow - 369km/h
C9:
No tow - 357-359km/h
Tow - 369km/h
R92CP:
No tow -
372km/h!
BUT...
Tow - 372-373km/h
Going to be an interesting one. I guess if you're by yourself, the R92CP is what you want. Probably to gap the new cars.
Jag is a bit heavy thru the first few esses at the start. Thought it'd be much faster with a tow. Same with the C9.
C9 is a bit wilder and tossable. Communicates actually better than the 787B.
962C, I can't call it. Felt like it took a long time to get up to speed on its own. Might struggle to shake the new cars.
787B doesn't have the grunt, even though it has that high terminal speed. Simply ear shattering for that 55seconds at full throttle.

All these years and it's still insane.
