The 2022 Toyota 4Runner relies on a tried-and-true formula that prioritizes rugged mechanical durability over modern fuel efficiency. Under its hood sits a naturally aspirated 4.0-liter V6 engine producing 270 horsepower and 278 lb-ft of torque, paired exclusively with an old-school five-speed automatic transmission. While this powertrain won't win any drag races or impress fuel economy purists, it delivers bulletproof reliability for trail riders and overlanders who care more about getting home than saving gas.
If you're shopping for a mid-size SUV that can handle severe trail abuse right off the showroom floor, understanding what makes this specific powertrain tick is essential. Let's break down the exact performance numbers, transmission behavior, and real-world trade-offs you'll live with.
Powertrain Specifications and Output
Every single trim level of the 2022 4Runner—from the base SR5 to the hardcore TRD Pro—shares the exact same engine block. You don't get a turbo-four or a hybrid option here.
- Engine Type: 4.0-Liter DOHC 24-Valve V6 with Dual Independent Variable Valve Timing with Intelligence (VTT-i)
- Horsepower: 270 hp at 5,600 rpm
- Torque: 278 lb-ft at 4,400 rpm
- Induction: Atmospheric (Naturally Aspirated)
- Fuel Requirement: Regular unleaded (87 octane)
This motor develops its peak torque relatively high up in the rev range at 4,400 rpm. When you're crawling over rocks, you'll rely heavily on low-range gearing to multiply that torque, because low-end grunt off-idle isn't as explosive as modern turbocharged competitors.
The Five-Speed Transmission Reality
The elephant in the room for any technical review of this vehicle is the five-speed automatic transmission. While most modern SUVs utilize eight, nine, or ten-speed gearboxes to balance highway cruising efficiency with snappy throttle response, the 4Runner sticks to its five-speed architecture.
- On-Road Impact: Because it has fewer ratios to choose from, highway passing maneuvers require deep throttle inputs, causing the engine to roar loudly as it kicks down a gear. RPMs sit higher at highway cruising speeds.
- Off-Road Benefit: Fewer electronic complications mean fewer failure points when exposed to deep water crossings, heavy dust, and extreme heat. Mechanical simplicity remains a core design philosophy for Toyota.
Drivetrain Options and Traction Systems
Power routes either to the rear wheels (2WD) or through one of two distinct four-wheel-drive systems, depending on the trim package you select.
Part-Time vs. Full-Time Four-Wheel Drive
- Part-Time 4WD System: Featured on SR5, TRD Off-Road, and TRD Pro models. It uses a dual-range transfer case with high and low modes for loose surfaces like dirt, mud, and snow. You shouldn't engage it on dry pavement.
- Full-Time 4WD System: Exclusive to the Limited trim. It incorporates a Torsen limited-slip center differential with a locking feature, constantly shifting power to the wheels with the best grip on wet or icy roads.
Towing Capacity and Real-World Utility
For owners looking to pull a small camping trailer, utility flatbed, or lightweight boat, the 4Runner maintains a respectable capability threshold.
- Maximum Towing Capacity: 5,000 pounds across all configurations.
- Receiver Hitch: Standard Class IV towing receiver with integrated 4- and 7-pin connectors.
- Payload Considerations: Loading up the cargo area with overlanding gear, rooftop tents, and extra fuel will eat into your payload capacity quickly, leading to noticeable rear-end sag unless upgraded suspensions are installed.
Fuel Economy Trade-Offs
You pay a heavy price at the fuel pump for the 4Runner's heavy-duty body-on-frame construction and old engine-transmission pairing.
- EPA Estimates: 16 mpg city, 19 mpg highway, and 17 mpg combined for both 2WD and 4WD variants.
- Real-World Experience: Upgrading to heavier all-terrain tires, adding roof racks, or slapping steel armor plates onto a TRD model easily drops real-world efficiency down into the 13–15 mpg range.

Frequently Asked Questions
Does the 2022 Toyota 4Runner require premium fuel?
No. The 4.0-liter V6 is designed to run completely fine on regular 87-octane gasoline, saving you money over the long haul during long road trips.
Can I tow with the TRD Pro model?
Yes, the TRD Pro retains the same 5,000-pound maximum towing limit as the rest of the lineup, though its soft off-road-tuned Fox suspension can feel a bit bouncier when a heavy trailer tongue weight is applied.
Why hasn't Toyota updated the 4Runner engine?
Toyota leans heavily on proven longevity. The 1GR-FE V6 engine architecture is widely regarded as bulletproof, capable of pushing past 300,000 miles with basic fluid maintenance, making mechanical evolution secondary to rock-solid reliability.
What is the fuel tank capacity?
The 2022 model features a large 23.0-gallon fuel tank, which helps offset poor fuel economy by maintaining a reasonable total driving range between fill-ups.
