Prices are per tier and per vehicle. Displayed effects are relative to stock: a later tier replaces the earlier setting rather than adding its modifier again.

Upgrades / 01

Upgrade System

Upgrade one vehicle at a time at the mechanic. Sixteen purchases across seven systems cost 675 Pebbles for a full set; that spending does not upgrade the rest of your garage.

Systems: 7
Purchases per vehicle: 16
Full upgrade budget: 675 Pebbles

Field notes

Engine, suspension, tyres, protection and water resistance each have two purchased tiers. Inventory and winch range each have three.

The complete budget is 75 Pebbles for each two-tier system and 150 for each three-tier system. Earlier purchases count toward the 675 total.

Upgrades / 02

Tyres & Grip

The two purchased tyre stages add 0.08 or 0.16 to stock grip. All 21 release vehicles have these upgrades; body size and engine class remain separate considerations.

Upgrades / 03

Liveries & Cosmetics

Change colours, liveries and accessories at merchants and cabins.

Field notes

Cosmetic choices change the vehicle’s appearance; mechanical upgrades are listed separately.

Upgrades / 04

Engine Stage 2

The first engine purchase improves torque and raises the speed limiter. The result depends on the vehicle class; Trail and Expedition engines do not gain the same numbers.

System: Engine
Release menu price: 25 Pebbles
Applies to: All 21 release vehicles
Trail torque: 100 → 106 N·m
Wagon torque: 125 → 138 N·m
Workhorse torque: 175 → 190 N·m
Expedition torque: 200 → 227 N·m

Upgrades / 05

Engine Stage 3

The upper engine tier takes each class to its strongest listed engine setting. Compare the Stage 3 torque in the vehicle list before choosing which rig to finish.

System: Engine
Release menu price: 50 Pebbles
Applies to: All 21 release vehicles
Trail torque: 106 → 112 N·m
Wagon torque: 138 → 151 N·m
Workhorse torque: 190 → 207 N·m
Expedition torque: 227 → 256 N·m

Upgrades / 06

Protection Stage 2

Reduce damage taken by 15% relative to the stock setup. Protection helps with impacts but does not remove the need to repair the vehicle.

System: Protection
Release menu price: 25 Pebbles
Applies to: All 21 release vehicles
Damage taken: -15%

Upgrades / 07

Protection Stage 3

The upper protection tier reduces listed damage taken by 30%. Its value is the final stock-relative modifier, not another 30% stacked onto Stage 2.

System: Protection
Release menu price: 50 Pebbles
Applies to: All 21 release vehicles
Damage taken: -30%

Upgrades / 08

Suspension Level 2

Add 8 cm to the stock suspension travel. The upgrade changes suspension travel rather than promising a fixed increase in clearance beneath every part of the body.

System: Suspension
Release menu price: 25 Pebbles
Applies to: All 21 release vehicles
Suspension travel: +8 cm

Field notes

The June Demo menu showed 20 Pebbles for the Protector. The release-day menu shows 25; use the current garage price.

Upgrades / 09

Suspension Level 3

The upper suspension tier adds 16 cm of travel relative to stock. Its listed effect replaces the earlier tier’s 8 cm value.

System: Suspension
Release menu price: 50 Pebbles
Applies to: All 21 release vehicles
Suspension travel: +16 cm

Upgrades / 10

Tires Stage 2

Add 0.08 to the tyre grip coefficient. This value is a coefficient adjustment, not an 8% speed or climbing bonus.

System: Tires
Release menu price: 25 Pebbles
Applies to: All 21 release vehicles
Grip coefficient: +0.08

Field notes

The June Demo menu showed 20 Pebbles for the Protector. The release-day menu shows 25; use the current garage price.

Upgrades / 11

Tires Stage 3

The upper tyre tier adds 0.16 to stock grip. Do not add the earlier tier’s 0.08 again when comparing the final setup.

System: Tires
Release menu price: 50 Pebbles
Applies to: All 21 release vehicles
Grip coefficient: +0.16

Upgrades / 12

Tool Slots — 2

Carry two equipped tools instead of the stock capacity. This is the first inventory purchase, not two extra slots added to the vehicle.

System: Inventory
Release menu price: 25 Pebbles
Applies to: All 21 release vehicles
Total tool slots: 2

Upgrades / 13

Tool Slots — 3

The second inventory purchase raises total capacity to three tools. It gives a recovery loadout room for another piece of field gear.

System: Inventory
Release menu price: 50 Pebbles
Applies to: All 21 release vehicles
Total tool slots: 3

Upgrades / 14

Tool Slots — 4

Four tools is the highest listed inventory capacity. This final slot costs more than either of the earlier inventory purchases.

System: Inventory
Release menu price: 75 Pebbles
Applies to: All 21 release vehicles
Total tool slots: 4

Upgrades / 15

Water Resistance 2

Increase the listed time before engine flooding by 50% relative to stock. The vehicle can still flood; this is extra tolerance rather than waterproofing.

System: Water Resistance
Release menu price: 25 Pebbles
Applies to: All 21 release vehicles
Time before flooding: +50%

Upgrades / 16

Water Resistance 3

Double the listed stock flooding time. The final water-resistance tier gives more recovery time without making deep water harmless.

Release menu price: 50 Pebbles
Applies to: All 21 release vehicles
Time before flooding: +100%

Upgrades / 17

Winch Stage 2

Reach attachment points 15% farther away than with the stock winch. Range changes do not establish a higher pulling force.

Release menu price: 25 Pebbles
Applies to: All 21 release vehicles
Winch range: +15%

Upgrades / 18

Winch Stage 3

Extend winch reach by 30% relative to stock. This is the middle range upgrade, before the longer Stage 4 cable reach.

System: Winch
Release menu price: 50 Pebbles
Applies to: All 21 release vehicles
Winch range: +30%

Upgrades / 19

Winch Stage 4

The final winch tier extends reach by 50% relative to stock. It is a range upgrade, not a stronger winch motor or a guaranteed recovery from every angle.

System: Winch
Release menu price: 75 Pebbles
Applies to: All 21 release vehicles
Winch range: +50%
