So I’ve been craving a racing rp for a few years now, with a focus mostly on the racers themselves and not so much the races, though I still want those to have an impact. I thought that using dice would be a good and fair way to determine what happens during a race, but I wanted to do a bit more than “roll the dice to see if you win or what place you get”.

My main goal is a system that’s not too crunchy, but still gives the feeling of vehicle stats mattering and adds a bit of chance. The players can add more descriptive flavor text based on what happens in the roll. Since I’m fairly inexperienced in this field, I would appreciate advice on simplifying, balancing, or tweaking to make this better. 

[hider=Racing System (using a d10):]

Dice Value meaning:
1-3: Complete Failure
4-6: A little success
7-9: Mostly success
10+: Full success

Stats and their meaning:

Think of level values themselves as stat bonuses to add onto a roll.
 
Turbo Acceleration Level (TAL): How fast the vehicle can go when the acceleration is hit; the higher the level, the quicker you can go in the less amount of time; stat doubles in the last lap

Turbo Acceleration Level 
+1-Takes a while to affect vehicle speed
+2-Takes some time
+3-kicks in almost right away

Durability Level (DL): How many hits the vehicle can tank; the higher the stat, the more hits you can take.

DL Level 1: 30 HP
DL Level 2: 40 HP
DL Level 3: 50 HP

Durability Level (must be opposite of TAL unless TAL is a 2)
+1- made of tinfoil
+2- can take a few hits
+3- practically a tank

Handling Level (HL): Reaction time of the vehicle to what a driver does; the higher the level, the better you can take sharp turns and avoid obstacles. 

Handling Level
+1-not good at sudden turns
+2- handles turns okay
+3- turns on a dime

Three possible actions a player can do:
-Accelerate (d10+ TAL)

1-3: Speed doesn’t increase enough to make a difference
4-6: Speed up to almost catch up to next higher-ranking vehicle
7-9: Speed up to be neck-and-neck with higher-ranking vehicle
10+: Overtake next higher-ranking vehicle, take an additional action

Attack (d10 + DL)

Damage dice: d10

1-3: Miss
4-6: nudge opponent; opponent rolls Handling with advantage to see if any damage is taken
7-9: hit opponent, sending them into a slight serve, opponent rolls Handling to see amount of damage is taken
10+: smash into opponent, sending them careening out of control; opponent rolls Handling with disadvantage if they remain in control, take an additional action

-Maneuver (avoiding obstacles, avoiding another vehicle, etc.) (d10 + HL)

1-3: Maneuver fails, take damage from hitting obstacle/barrier/vehicle
4-6: Maneuver succeeds, but not without a hitch, take half damage 
7-9: Maneuver succeeds, take no damage
10+ Maneuver succeeds, take an additional action

If this works fine, I might play around with giving players the opportunity to upgrade vehicle stats to increase their bonuses more via temporary equipment. Like I said, I don’t want this to get overly crunchy. 

Thanks a bunch for your help. Even if this rp never happens, I can put this in my back pocket and use it for future endeavors. Feel free to ask any questions if something’s unclear.
