The Toyota Tacoma offers two main drivetrain layouts: rear-wheel drive (RWD) and part-time four-wheel drive (4WD). These systems pair with gasoline and hybrid powertrains, depending on the trim level.
2025 Brown Toyota Tacoma
The Tacoma uses a body-on-frame platform with a front-engine layout. Power transfers through an automatic transmission to the rear wheels or to all four wheels when equipped with 4WD.
Rear-Wheel Drive Configuration
Rear-wheel drive is standard on select Toyota Tacoma models.
Layout and Operation
In a rear-wheel drive Tacoma:
- The engine sends power through the transmission.
- A driveshaft transfers power to the rear differential.
- The rear wheels provide propulsion.
The front wheels handle steering duties only.
Use Case
Rear-wheel drive suits:
- Daily commuting
- Highway driving
- Light cargo transport
- Towing within rated capacity
This layout offers a simple mechanical setup and supports balanced weight distribution when the truck carries cargo in the bed.
Part-Time Four-Wheel Drive System
The Toyota Tacoma offers a part-time 4WD system on specific trims.
System Structure
The part-time 4WD system includes:
- A transfer case
- Front and rear differentials
- A front driveshaft
- Electronic or mechanical shift control
The driver can select between drive modes based on road conditions.
4WD Modes
Common drive selections include:
- 2H (two-wheel drive high range)
- 4H (four-wheel drive high range)
- 4L (four-wheel drive low range)
In 2H mode, the truck operates in rear-wheel drive.
In 4H mode, the system distributes power to both front and rear axles for improved traction on loose or slippery surfaces.
In 4L mode, the transfer case engages a lower gear ratio. This mode supports low-speed control in off-road or steep terrain conditions.
Part-time 4WD systems require appropriate surface conditions when engaged, such as snow, gravel, mud, or dirt.
Engine and Transmission Integration
The drivetrain connects directly to the engine and transmission.
Gasoline Engine Configuration
The Toyota Tacoma offers a turbocharged 2.4-litre four-cylinder gasoline engine.
This engine pairs with:
- An 8-speed automatic transmission
The transmission transfers torque to either the rear axle or to both axles in 4WD models.
Hybrid Powertrain Configuration
Select Tacoma models use the i-FORCE MAX hybrid system.
This hybrid system combines:
- A turbocharged 2.4-litre four-cylinder engine
- An electric motor integrated within the transmission housing
- A hybrid battery pack
The electric motor assists the gasoline engine. Power continues through the same drivetrain layout, either rear-wheel drive or part-time four-wheel drive, depending on the model.
The hybrid configuration does not replace the mechanical drivetrain. Instead, it adds electric motor support within the transmission system.
Transfer Case Function
The transfer case plays a central role in four-wheel drive models.
Power Distribution
In 4WD mode:
- The transfer case divides torque between the front and rear driveshafts.
- Both axles receive power.
In low-range mode:
- The transfer case uses a lower gear ratio.
- Wheel torque increases at lower speeds.
This setup supports controlled movement on uneven terrain.
Differential Systems
The Tacoma drivetrain includes front and rear differentials.
Rear Differential
All models include a rear differential. It allows the rear wheels to rotate at different speeds during cornering.
Some trims may include an electronically controlled locking rear differential. When engaged:
- Both rear wheels rotate at the same speed.
- Traction increases on uneven surfaces.
Front Differential
Four-wheel drive models include a front differential. It performs the same speed-balancing function for the front wheels.
Suspension and Drivetrain Connection
The drivetrain works with the Tacoma suspension system.
The front suspension uses a double wishbone design. The rear suspension uses a multi-link setup with coil springs on current-generation models.
This design supports:
- Wheel articulation
- Load stability
- Off-road control
The drivetrain components mount within the frame structure, which supports towing and payload capacity.
Towing and Payload Relationship
Drivetrain configuration affects towing and payload performance.
The Toyota Tacoma offers a maximum towing capacity up to approximately 2,948 kilograms when properly equipped.
Payload capacity depends on trim and drivetrain selection.
Four-wheel drive models may have slightly different weight ratings due to additional drivetrain components.
Drive Mode Selection
Four-wheel-drive Tacoma models include a drive-mode selector.
The system allows the driver to switch between:
- Rear-wheel drive
- Four-wheel drive high
- Four-wheel drive low
The shift process may occur electronically through a dial or switch, depending on trim level.
This setup supports flexibility across different terrain types.
Electronic Traction Systems
The drivetrain integrates with traction control and stability systems.
These systems monitor wheel speed and adjust engine output or braking force when slip occurs.
When paired with 4WD and a locking rear differential, the Tacoma can maintain traction in low-grip conditions.
Electronic systems work in coordination with mechanical drivetrain components.
Hybrid Drivetrain Characteristics
The i-FORCE MAX hybrid system adds electric torque assistance.
The electric motor sits within the bell housing between the engine and transmission.
This placement allows:
- Direct torque transfer to the transmission
- Seamless integration with rear-wheel or four-wheel drive layouts
The hybrid battery stores energy recovered during deceleration. The electric motor supports acceleration and low-speed torque delivery.
The mechanical transfer case and differentials operate the same way as in gasoline-only models when equipped with 4WD.
