Here's my latest lookup list for R3E cars. Updated 27/4/19 Physics: Old: prior to mid-2015 "floaty". Still loved by many though, especially DTM 92. New: mid-2015 to mid-2017. Improved - not floaty. Newest: the latest physics (since mid-2017) from Alex Hodgkinson ** Physics marked with two stars - Alex has advised that these car sets are currently being updated (as at 26/4/19) ABS: whether or not the cars in class have factory ABS - note that ABS can still be turned on/off as desired for all cars (multiplayer restrictions may apply and penalties apply for using 'artificial' ABS on cars without factory ABS). TC: whether or not the cars in class have factory traction control - note that traction control can still be turned on/off as desired for all cars (multiplayer restrictions may apply and penalties apply for using 'artificial' TC on cars without factory TC). TP: whether or not the cars in class have adjustable tyre pressures. NOTE: a number of other cars currently appear to have adjustable tyre pressures but Alex has advised that changes to these make no difference. The cars shown here DO have adjustable pressures as listed in the development notes. Thanks Alex! PI: a value that defines the performance of every car class. Some Classes that fall under the same Balance of Performance (BOP) share the same Performance index. That means these classes will be grouped together on the grid and listed as one class in the results. ID: ID for these cars in game Blank means I didn't have the information. Thanks to @Georg Ortner and @OtterNas3 for posting information on PI and IDs. Any errors in translation are mine. Let me know of any errors/ omissions and I will fix.
