Between seasons there have been several changes in cars lineup,here is the overview:
First of all there was a car with rather low performance,which was supposed to be put on voting between the seasons if it should stay. However the car received update from it's creator,which made it heavier,thus rendering the car even more uncompetitive,therefor no voting was required as organization decided to retire the car from RandomCar by default.

The VGI-6 TEDAVI was drawn 17 times through the season of 2023,it's highest qualifying result was 6th position (achieved by S1DUS*FasT in round 4 at Kyoto National Rev.) and it's best finishing result was 14th (achieved by B2マ Rayman in round 6 at Lindoring). The car finished 24th in 2023 Manufacturers championship,scoring 23 points in 5 attended rounds.

Between seasons 2 RandomCar eligible cars have received approved status,which grants addition to the series lineup by default:
First of those is
FEND TORUS,an all wheels driven sedan which will become the most powerful and also the 2nd heaviest car in the list. It will receive 4% restrictor as balancing measure.

2nd approved status car is
SALIVA15,a japanese coupe with pretty much equal performance to the LFS's standard TBO class,therefor it will join the league without any kind of balancing.

2 cars have been added via voting - one of those is an approved status car that has more than 300N@40m/s total downforce,which allows cars to be added by default,therefor the
DORITO FD7 had to receive users approval first and it succeeded. The coupe with a simulated rotary engine will start it's journey in RC with 13% air restrictor.

The new addition from standard voting is the new lightest car in the list -
STELLAR K61 tipps the scales to 841kg together with it's 80kg additional weight required for balancing,while with 190 horsepower it is also the least powerful car in the series.
6 cars have received update in balancing between the seasons:
COQUETTE Z5 - restrictor reduced to 27% (-1%)
FRAUD WHEELER E2 - restrictor reduced to 12% (-1%)
Raceabout 06 - restrictor reduced to 16% (-1%)
TALOT SUNS LOMIS - weight ballast incresed to 102kg (+2kg to balance out LFS update's caused difference)
XF COUPE TURBO - weigth ballast reduced to 25kg (-5kg)
XF TURBO 5 - weight ballast of 10kg (previously no balancing)
Votings to add new cars will be made only twice in 2024 - 1st is set between rounds 3 and 4,but 2nd voting will be held between rounds 6 and 7. Both these voting will feature 3 cars nominated by round winners,2nd best car from previous voting and 1 car nominated from organization.
