2026 Toyota 4Runner Engine Specs and Towing Capacity
The sixth-generation Toyota 4Runner continues into 2026 with a turbocharged four-cylinder powertrain family in place of the old V6, built on Toyota’s TNGA-F body-on-frame platform for more power, better efficiency, and off-road durability. This guide covers the 4Runner’s two engines, drivetrain options, and towing capability for drivers across San Juan Capistrano and South Orange County.
i-FORCE and i-FORCE MAX: Two Turbocharged Powertrains
Two engines anchor the 2026 lineup, and both pair with an 8-speed automatic transmission that replaces the outgoing five-speed.
The standard i-FORCE is a 2.4-liter turbocharged inline-four making 278 horsepower and 317 lb-ft of torque. Without a hybrid battery, it’s lighter and preserves maximum cargo space behind the rear seats.
The available i-FORCE MAX hybrid adds a 48-horsepower electric motor and a 1.87-kWh nickel-metal hydride battery for a combined 326 horsepower and 465 lb-ft of torque — the most powerful 4Runner ever. Peak torque arrives near 1,700 rpm, so power builds instantly off the line with no turbo lag. The Trailhunter is rated at 323 horsepower due to its unique exhaust and intake.
| Specification | i-FORCE | i-FORCE MAX Hybrid |
|---|---|---|
| Engine | 2.4L turbocharged I4 | 2.4L turbocharged I4 + electric motor |
| Horsepower | 278 hp | 326 hp (323 hp on Trailhunter) |
| Torque | 317 lb-ft | 465 lb-ft |
| Electric Motor / Battery | — | 48 hp motor / 1.87-kWh NiMH |
| Transmission | 8-speed automatic | 8-speed automatic |
Drivetrain Options: RWD, Part-Time 4WD, and Full-Time 4WD
The 4Runner offers three drivetrain setups, summarized below. Every i-FORCE MAX hybrid comes standard with four-wheel drive.
| Drivetrain | Key Hardware | Availability |
|---|---|---|
| Rear-Wheel Drive (RWD) | Automatic limited-slip differential (Auto LSD) | Standard on SR5, TRD Sport, Limited |
| Part-Time 4WD | Two-speed (high/low) electronic transfer case, A-TRAC, Auto LSD | Standard on off-road grades; available on RWD trims |
| Full-Time 4WD | Electronic locking center differential | Limited and Platinum |
Which Trims Get the Hybrid Powertrain
The i-FORCE MAX hybrid is standard on the Platinum, TRD Pro, and Trailhunter, and available on the TRD Off-Road, TRD Off-Road Premium, and Limited. The SR5, TRD Sport, and TRD Sport Premium come only with the gas i-FORCE. Because the hybrid battery sits beneath the rear cargo floor, hybrid models are five-passenger only — the available third-row seat (seven passengers) is offered on the gas SR5 and Limited.
| Hybrid Availability | Trims |
|---|---|
| Standard (i-FORCE MAX) | Platinum, TRD Pro, Trailhunter |
| Available option | TRD Off-Road, TRD Off-Road Premium, Limited |
| Gas i-FORCE only | SR5, TRD Sport, TRD Sport Premium |
Maximum Towing Capacity of the 2026 4Runner
Properly equipped, the 2026 4Runner tows up to 6,000 pounds with the gas i-FORCE engine across most of the lineup, including the base SR5. The hybrid top trims (Platinum, Trailhunter, TRD Pro) are rated at 5,800 pounds due to their added equipment weight — both figures clear the old V6’s 5,000-pound maximum.
That capacity handles small boats, utility trailers, ATV and canoe carriers, and light-to-midsize campers. Near the limit, weigh the loaded trailer and keep tongue weight within Toyota’s guidance — see the owner’s manual and door-jamb label for your configuration.
| Powertrain | Trims | Maximum Towing (Properly Equipped) |
|---|---|---|
| i-FORCE (gas) | SR5, TRD Sport, TRD Sport Premium, TRD Off-Road, TRD Off-Road Premium, Limited | 6,000 lbs |
| i-FORCE MAX (hybrid) | Platinum, Trailhunter, TRD Pro | 5,800 lbs |
Maximum towing and payload capacity figures are based on properly equipped vehicles and vary by configuration. Do not exceed any weight rating. See your owner’s manual and the vehicle’s door-jamb label for specific capacities.
Towing Technology and Trailering Aids
Every 4Runner has an integrated hitch and 4-/7-pin wiring, with additional trailering aids available in the Tow Technology Package (detailed below). Tow/Haul mode holds steady speeds and reduces gear hunting under load.
Off-road, CRAWL Control manages throttle and braking over obstacles, Multi-Terrain Select tunes traction for mud, dirt, and sand, and Downhill Assist Control handles steep descents.
| Towing Feature | Function | Availability |
|---|---|---|
| Integrated hitch & wiring harness | Receiver hitch with 4- and 7-pin connectors | Standard |
| Integrated trailer brake controller | In-dash gain and manual output controls on the Multi-Information Display | Tow Technology Package |
| Trailer Backup Guide with Straight Path Assist | Uses cameras and sensors to help keep a trailer straight while reversing | Tow Technology Package |
| Digital rear-view mirror | Camera-fed mirror view unobstructed by cargo or trailer | Tow Technology Package |
| Blind Spot Monitor (trailer-aware) | Extends detection zone to cover an attached trailer | Standard |
| Tow/Haul mode | Sharpens throttle and transmission response, reduces gear hunting under load | Standard on all i-FORCE MAX; most others |
Off-Road Geometry and Ground Clearance
Ground clearance and approach geometry climb with the trim tier, from the SR5 up to the TRD Pro and Trailhunter’s taller suspensions and high-clearance bumpers (see below). A 19-gallon fuel tank supports longer trips between fill-ups.
| Trim Tier | Ground Clearance | Approach Angle | Departure Angle |
|---|---|---|---|
| SR5 | 8.1 in | 18° | 22° |
| TRD Off-Road | 9.1 in | 33° | 24° |
| TRD Pro / Trailhunter | Up to 10.1 in | 33° | 24° |
Engineering Behind the Turbocharged Engine
The 2.4-liter i-FORCE was engineered for the high-load demands of Toyota’s TNGA-F trucks and SUVs — it’s the same engine family used in the current Tacoma — so the move from V6 to turbo four doesn’t come at the expense of durability. Its specifications and Toyota’s warranty coverage are summarized below.
| Engine Detail | Specification |
|---|---|
| Displacement | 2,393 cc (2.4L) |
| Configuration | Turbocharged inline-4, aluminum block |
| Valvetrain | 16-valve DOHC with dual variable valve timing |
| Compression Ratio | 11.0:1 |
| Transmission | 8-speed automatic |
| Coverage | Term |
|---|---|
| Basic (bumper-to-bumper) | 3 years / 36,000 miles |
| Powertrain | 5 years / 60,000 miles |
| Hybrid components | 8 years / 100,000 miles |
| Hybrid battery | 10 years / 150,000 miles |
| ToyotaCare maintenance | 2 years / 25,000 miles |
| Roadside assistance | 2 years / unlimited miles |

EPA-Estimated Fuel Economy
The turbocharged engine improves efficiency over the old V6. Rear-wheel-drive gas trims (SR5, TRD Sport, TRD Sport Premium) carry a projected EPA-Estimated 20 city / 26 highway / 22 combined rating; four-wheel-drive gas trims are rated at an EPA-Estimated 19 city / 25 highway / 21 combined, and the Limited RWD at 20/24/22. Every i-FORCE MAX hybrid returns an EPA-Estimated 23 city / 24 highway / 23 combined.
| Configuration | EPA-Est. City | EPA-Est. Highway | EPA-Est. Combined |
|---|---|---|---|
| Gas i-FORCE, RWD (SR5, TRD Sport, TRD Sport Premium) | 20 | 26 | 22 |
| Gas i-FORCE, 4WD (SR5, TRD Sport, TRD Off-Road) | 19 | 25 | 21 |
| Gas i-FORCE, Limited RWD | 20 | 24 | 22 |
| i-FORCE MAX Hybrid (all) | 23 | 24 | 23 |
EPA-estimated fuel economy figures are for comparison purposes only. Your actual mileage will vary depending on driving conditions, how you drive and maintain your vehicle, battery age/condition, and other factors.
How the 4Runner Compares: Towing vs. Bronco and Wrangler
Among body-on-frame off-road SUVs, the 4Runner’s towing rating leads its two closest rivals. The Ford Bronco tows up to 3,500 pounds across nearly all configurations, rising to 4,500 pounds only on the 3.0-liter Raptor. The Jeep Wrangler tops out at 5,000 pounds, and only on select four-door models with the appropriate axle ratio. The 2026 4Runner’s 6,000-pound maximum (gas trims) is a meaningful, practical advantage — enough to bring a larger camper or a second watercraft that would otherwise stay home.
| Model | Maximum Towing | Notes |
|---|---|---|
| 2026 Toyota 4Runner | 6,000 lbs | Gas i-FORCE, most trims (5,800 lbs on hybrid top trims) |
| Ford Bronco | 3,500 lbs | 4,500 lbs on the 3.0L Raptor only |
| Jeep Wrangler | 5,000 lbs | Select four-door models with the appropriate axle ratio |
Frequently Asked Questions
Does the i-FORCE MAX hybrid require plug-in charging?
No. It’s a self-charging hybrid that uses regenerative braking and the gasoline engine to charge its battery automatically as you drive — there’s no plug.
What transmission does the 2026 4Runner use?
Both engines pair with an 8-speed automatic transmission, which replaces the previous five-speed for smoother, quicker shifts.
Does the hybrid battery affect third-row seating?
Yes. The hybrid battery sits under the cargo floor, so hybrid models are five-passenger only. The available third-row seat is offered on the gas SR5 and Limited.
What off-road suspension do the top trims use?
The TRD Pro rides on FOX 2.5-inch internal-bypass QS3 shocks with remote reservoirs and a standard Stabilizer Disconnect Mechanism; the Trailhunter uses Old Man Emu 2.5-inch forged monotube shocks tuned for overlanding loads.
Is a full-time four-wheel-drive system available?
Yes. The Limited and Platinum offer full-time 4WD with an electronic locking center differential. Other four-wheel-drive trims use a part-time system with a two-speed transfer case.
