5.1. All variables in Play-to-Earn mode are divided into two categories, mechanics-related and metagame-related. The mechanical parameters are any parameters pertaining to a specific car.
The metagame parameters include all kinds of slots, unlocks, statistical parameters and other numeric parameters.
Cars consist of a number of key components. Below is an explanation how tuning affects them.
Every car has a set of predetermined basic variables, but these variables are all provided by detachable parts. Hence, a car is not merely a spec sheet, but rather a set of preinstalled parts with their own attributes. Swapping these parts for others changes the attributes.
Aerodynamic and exterior styling parts determine the appearance of the car:
- front bumper; - rear bumper; - front apron; - arch flare; - side skirts; - rear spoiler (rear wing); - headlights and taillights; - wheels. These parts add bonuses to economic (i.e., non-gameplay) indicators: - fuel expenditure per race; - car wear-and-tear; - experience bonuses; and so on.
Engine parts that affect the Speed attribute are: - filters; - pistons; - exhaust system.
Transmission parts that affect the Acceleration attribute are: - flywheel; - gearbox; - clutch.
Brake system parts that effect the Handling attribute are: - wheels; - brakes; - shock absorbers.
5.2. Upgrading a car in Drive-to-Earn mode requires players to: - Accumulate enough experience points based on the individual car and its level; - Procure certain car parts also based on the requirements of the car and its level.
Each NFT level-up also leads to the improvement of its main attributes: - Car wear-and-tear – once this indicator reaches 0, players can no longer use the car until repaired; - Speed is an indicator proportional to token farming per 1 unit of fuel; - Tank is the volume of the fuel tank; - Fuel Economy is an indicator showing fuel consumption for 1 km of driving.
