11 specifications across 5 groups, covering stock setup, dimensions and components.

Basis
Vehicle
Power
A brushed motor carries current through carbon brushes that rub on the commutator.
It is cheaper and smooth at low speed.
The brushes wear and the motor loses power over time.
Scale
The maker's nominal size compared with a full-size vehicle. It works more as a class label than a measurement.
A 1/10 monster truck is far bigger than a 1/10 touring car, so compare length and weight for real size.
Part number
The maker's product number for this exact version.
A V2, a new color, or a kit instead of an RTR usually has a different number, and parts can differ between them.
Check it against your box or receipt before ordering parts.

Drivetrain
Pinion
The small gear on the motor shaft. Fewer teeth gear the car shorter: quicker acceleration, lower top speed and a cooler motor. More teeth do the opposite.
It depends on the motor you fit, so the maker does not list one.
Spur
The large gear the pinion drives. A bigger spur with the same pinion gears the car shorter.
Pinion and spur must have the same pitch, or tooth size, to mesh.
Transmission & axle
Every reduction after the spur, multiplied together: transmission, differentials and axle gears.
It is fixed by the design; the gearing you change is the pinion and spur.
Final drive
How many times the motor turns for one turn of the wheels. A higher number is shorter gearing: more acceleration and pulling power, less top speed.

Wheels & tires
Tire diameter
The outside diameter of the mounted tire, tread to tread. A taller tire covers more ground each turn, which gears the car taller.
At high speed tires can balloon and grow, so the real gearing gets taller as the car goes faster.

Power
Motor
Brushed motors are rated by can size and turns rather than KV, so there is no KV to show.
Battery
The highest LiPo cell count the maker rates the electronics for.
The maker does not publish it.

Theoretical top speed
A brushed motor has no KV rating, so no theoretical top speed is worked out. Compare gearing by rollout instead.

How to read these figures
Stock is as the vehicle ships.
Calculated is worked from the stock figures on this page rather than stored beside them, so the two cannot drift apart.
Not applicable means the vehicle does not come with it, like the motor on a roller or the tires on a race kit, or does not have one, like a KV rating on a brushed motor.
Not published means it exists but no source we could find prints it.
