2026 Toyota 2.4L Turbo Engine Powertrain

The 2026 Toyota 2.4L turbocharged 4-cylinder engine gives Toyota non-hybrid SUVs and trucks strong low-speed response from a smaller engine. Commonly identified as T24A-FTS in Toyota technical materials, it powers gas versions of the Highlander, Grand Highlander, Tacoma, and 4Runner.

This engine replaced older V6 powertrains in several Toyota models and also serves as the foundation for hybrid systems such as i-FORCE MAX and Hybrid MAX. This page focuses on the non-hybrid gas version.

Engine System

The 2.4L turbocharged Toyota engine is built to deliver strong torque early, then support that response with D-4S dual injection, Dual VVT-i valve timing, and an 8-speed automatic transmission in most gas models. Output varies by vehicle application, with Highlander and Grand Highlander gas models rated at 265 hp, while Tacoma and 4Runner models reach up to 278 hp and 317 lb-ft of torque.

How the System Works

The 2.4L turbocharged engine uses a turbocharger to make torque early in the rpm range. In the Highlander application, peak torque arrives low in the rev range, which helps the engine respond when pulling away from a stop, merging, climbing grades, passing, or towing.

Toyota's D-4S dual injection system uses both direct injection and port injection. Direct injection supports power under load, while port injection supports clean combustion during lighter driving. The system changes fuel delivery based on engine demand rather than relying on only 1 injection method.

Dual VVT-i adjusts valve timing across the rpm range. That allows the engine to respond to different driving conditions, from light throttle cruising to heavier acceleration.

The gas engine covered here should be separated from Toyota's hybrid systems that use the same basic engine layout. Highlander, Grand Highlander, Tacoma, and 4Runner gas models use the engine without electric motor assistance. Hybrid MAX and i-FORCE MAX applications pair the 2.4L turbo with electrified hardware, different system tuning, and a high-voltage hybrid battery.

Vehicles Powered by the 2.4L Turbocharged Engine

Four Toyota models use the 2.4L turbocharged engine in non-hybrid form: Highlander, Grand Highlander, Tacoma, and 4Runner. The same engine family appears across these vehicles, but Toyota tunes output, transmission choices, and vehicle role differently by platform.

Toyota Highlander (2026)

The 2026 Toyota Highlander uses the 2.4L turbocharged gas engine across XLE, XSE, Limited, and Platinum gas trims. The engine produces 265 hp and 310 lb-ft of torque. The Highlander gas model uses the Direct Shift-8AT 8-speed automatic transmission and is rated at up to 5,000 lbs of towing capacity. The 2026 Highlander gas model earns an EPA-estimated 21/28/24 mpg city/highway/combined.

Engine Comparison

Toyota's 2.4L turbocharged gas engine is most useful to compare against 2 powertrain directions: the older V6 engines it replaced, and the Toyota hybrid systems that use the 2.4L turbo with electric assist.

Compared to the Older V6 Engines It Replaced

Spec	2.4L Turbocharged Engine	Previous V6 Engines
Vehicles	Highlander, Grand Highlander, Tacoma, 4Runner	Prior Highlander, Tacoma, and 4Runner applications
Engine layout	Turbocharged Inline-4	Naturally aspirated V6
Highlander / Grand Highlander output	265 hp	Replaced the prior Highlander V6 powertrain
Tacoma / 4Runner output	Up to 278 hp, up to 317 lb-ft	Replaced the previous-generation Tacoma V6 and the previous 4Runner V6
Torque behavior	Strong torque arrives low in the rpm range	Larger displacement, less turbo-assisted low-rpm torque
Transmission	8-speed automatic, with Tacoma manual option on select trims	Varies by older application

The 2.4L turbocharged engine gives Toyota a smaller gas engine with stronger early torque than the older V6 applications it replaced. That matters most when accelerating from low speed, merging onto the highway, climbing grades, or moving a loaded SUV or truck. The trade-off is character: shoppers used to Toyota's older V6 engines may notice the different feel of a turbocharged 4-cylinder.

Compared to Toyota Hybrid Versions of the 2.4L Turbo

Spec	Gas 2.4L Turbo	Hybrid 2.4L Turbo Applications
Vehicles	Highlander, Grand Highlander, Tacoma, 4Runner gas models	Tacoma i-FORCE MAX, 4Runner i-FORCE MAX, Land Cruiser, Crown Platinum, Grand Highlander Hybrid MAX
Engine role	Main gas power source	Gas engine paired with electric motor assistance
Hybrid battery	Not used	High-voltage hybrid battery
Driving priority	Gas power, towing, torque, broad availability	More power, electric assist, or performance-focused hybrid tuning
Transmission	Direct Shift-8AT 8-speed automatic, with Tacoma manual option on select trims	Depends on hybrid system and vehicle

The gas 2.4L turbo is the simpler choice for shoppers comparing Toyota's non-hybrid SUVs and trucks. i-FORCE MAX and Hybrid MAX models add electric motor assistance, a high-voltage battery, and different system tuning. The key difference is simple: gas models use the engine as the main power source, while hybrid versions use it as part of an electrified powertrain.

Service and Maintenance

The 2.4L turbocharged engine needs routine gas-engine maintenance, including oil changes, filter replacements, fluid checks, tire rotations, and inspections at factory-recommended intervals. Turbocharged engines also make proper maintenance important because the turbocharger, cooling system, oil system, and fuel system all work together under load.

Every new Toyota Highlander, Grand Highlander, Tacoma, and 4Runner at Mike Kelly Toyota comes with ToyotaCare, which covers normal factory-scheduled maintenance for 2 years or 25,000 miles, whichever comes first, plus 2 years of unlimited-mileage roadside assistance. ToyotaCare Plus is available as an extension for owners who want longer coverage.

Factory-trained service technicians can inspect the engine, transmission, fuel system, cooling system, filters, fluids, and related components during scheduled visits. For Toyota owners in Western Pennsylvania, Mike Kelly Toyota can handle scheduled service for Highlander, Grand Highlander, Tacoma, and 4Runner models with the 2.4L turbocharged engine.

Driving the 2.4L Turbo in Western Pennsylvania

Western Pennsylvania driving makes low-rpm torque useful. Drivers in Uniontown, Connellsville, Brownsville, Waynesburg, Hopwood, and nearby communities deal with hills, highway merges, rural routes, and changing elevation, all places where early engine response helps a vehicle feel more confident without needing to rev hard.

The 2.4L turbo torque curve fits regional SUV and truck use. Route 40, Route 119, Laurel Highlands trips, and drives toward Morgantown, WV can involve grades, passing zones, winter conditions, and loaded family travel. In the Highlander and Grand Highlander, the engine supports 3-row utility with up to 5,000 lbs of towing capacity. In the Tacoma and 4Runner, it supports truck and trail-oriented use with more torque than the older V6 applications it replaced.

Fuel economy also matters for Western Pennsylvania drivers who split time between small-town driving and longer highway trips. The 2026 Highlander 2.4L turbo earns an EPA-estimated 21/28/24 mpg city/highway/combined, while the 2026 Tacoma i-FORCE offers an EPA-estimated highway rating of up to 26 mpg. For shoppers moving out of older V6 SUVs or trucks, those figures help explain why Toyota shifted this part of the lineup to a smaller turbocharged engine.
