The difference between a 300 I and 350 R would be the difference between an E 92 and an E 92 M 3 GTS . The M 50 is the Formula car , obviously . Whether the 350 R ' s track only setup is justifiable or not remains to be seen . There ' s no way for you , or anyone else , to make that declaration so early . 1 . M 50 vs 350 r is a balance consideration , extremely likely to be tweaked and changed . By the way , Ben has said that the M 50 is the fastest without upgrades but not the fastest with upgrades . 2 . We don ' t know how profitable racing is . If the 350 R is an amazing racer , it sounds like that would make it worth it to have as a track only vehicle . So far they ' ve talked about shipping your racer to the track , rather than flying it there . Sure , there may be some guys who ride their race cars to the track , but most people don ' t . 3 . We only have a few tracks . Tuning , the track , the type of race , etc . will all play a role in a ship ' s performance . We know there are longer distance races . In this case the M 50 may have to stop to be refueled or at least slow down to what a Starfarer travels at . 4 . For all we know , the M 50 and 350 R do not compete with eachother . Just as an F 1 car does not compete with a GT car . As for the performance difference between a 350 R and a 300 i , both those ships are in for a rework . Not to mention there was quite a large difference in both acceleration and handling . The 350 R is significantly faster . I ' d love to see a comparison of the two on the same map , but I had a 300 i as a loaner and that thing is a dog .
