Treehouse Moderator 68,468 PointsYou are on the right path. Here are some items to fix:
- in run_laps, the attributefuel_remainingneeds to beself.fuel_remaining- also, look for missing underscore and "remaning" typos
 
- the attribute lapsshould be referenced asself.laps
- In __init__, either setself.laps = 0or addlaps=0to parameter list and setself.laps = laps
Post back if you need more help. Good luck!!
