How the Toyota Hybrid System Works

In the seven 2026 Toyotas that use the 2.5-liter hybrid engine, the gas engine and electric motor power work together to move the vehicle. The Camry, Crown Signia, Grand Highlander Hybrid, Highlander Hybrid, RAV4 Hybrid and Sienna use an electronically controlled continuously variable transmission (ECVT). Toyota rates the engine and motors working together as net system horsepower. That is Toyota's own figure for the whole hybrid system, not the engine's horsepower plus the motor ratings added up.

The engine works with the parts below, and some of them change from model to model:

Front electric motor: On the RAV4 Hybrid, for example, the front electric motor drives the front wheels and recovers energy when you brake.
Rear electric motor: On the RAV4 Hybrid and the Sienna, all-wheel drive adds a separate rear electric motor. The Crown's 2.5-liter grades and the Crown Signia come only with all-wheel drive and carry both a front and a rear electric motor.
Regenerative braking: The Camry, Crown, Crown Signia and RAV4 Hybrid build regenerative braking into an electronically controlled braking system, so slowing down also recovers energy.
EV mode: The 2026 Camry's and RAV4 Hybrid's drive modes include Eco, Normal, Sport and EV, and the 2026 Crown and Crown Signia also offer EV mode. EV mode lets you drive solely on battery power at low speeds, for short distances and in limited circumstances, such as in a parking garage. Some conditions may prevent or limit its use, and your Owner's Manual explains how to use it and its limits.
Hybrid battery: The Camry and RAV4 Hybrid use a sealed lithium-ion battery, while the Sienna, Grand Highlander Hybrid, Crown and Crown Signia use a nickel-metal hydride battery.

Camry

Every 2026 Camry is a hybrid, so every grade uses the 2.5-liter engine and comes with front-wheel drive or all-wheel drive. Of the seven 2026 2.5-liter hybrids, the Camry LE with front-wheel drive has the highest EPA combined rating. You can compare the grades across our new Toyota Camry models for sale.

RAV4 Hybrid

The 2026 RAV4 Hybrid's XSE, Woodland Edition and Limited grades come only with all-wheel drive, while the LE, SE and XLE Premium also offer front-wheel drive. If you'd rather have front-wheel drive, look for the LE, SE or XLE Premium among our new Toyota RAV4 models for sale.

Crown

The 2026 Crown uses the 2.5-liter hybrid in its XLE, Nightshade and Limited grades, and all 3 have all-wheel drive. The Crown Platinum uses the 2.4-liter turbocharged Hybrid MAX instead, which Toyota rates at 340 net horsepower. When you shop our new Toyota Crown models for sale, check the grade so you know which powertrain you're getting.

Crown Signia

Unlike the Crown, the 2026 Crown Signia uses the 2.5-liter hybrid in both of its grades, the XLE and Limited, and each comes with all-wheel drive. Get to know the Toyota Crown Signia before you choose between them.

Sienna

Every 2026 Sienna is a hybrid. Its LE, XLE, XSE, Woodland Edition, Limited and Platinum grades all use the 2.5-liter engine. The Sienna's net system rating stays the same with front-wheel or all-wheel drive, matching the Grand Highlander Hybrid's as the highest of the seven 2026 2.5-liter hybrids. If the Sienna is on your list, see our new Toyota Siennas for sale.

Highlander Hybrid

The 2026 Highlander Hybrid comes standard with all-wheel drive in every grade: the Hybrid XLE, Hybrid Limited and Hybrid Platinum. So when you browse our new Toyota Highlander Hybrid models for sale, the drivetrain is already settled.

Grand Highlander Hybrid

The 2026 Grand Highlander Hybrid comes in Hybrid LE, Hybrid XLE, Hybrid Limited and Hybrid Nightshade grades, with front-wheel drive or all-wheel drive. If you want more power, the Grand Highlander also comes with Hybrid MAX, rated at 362 net horsepower. It pairs a 2.4-liter turbocharged four-cylinder with a 6-speed automatic transmission and full-time electronic all-wheel drive. To start shopping, see our new Toyota Grand Highlanders for sale.

Engine Output by Model

Toyota rates the 2.5-liter engine on its own, apart from the electric motors. That engine-only output shifts a little from one 2026 model to the next.

Model	Engine-Only Horsepower	Engine-Only Torque
Camry	184 hp at 6,000 rpm	163 lb-ft at 3,600 to 5,200 rpm
RAV4 Hybrid	183 hp at 6,000 rpm	163 lb-ft at 3,600 to 5,200 rpm
Crown (XLE, Limited, Nightshade)	184 hp at 6,000 rpm	163 lb-ft at 5,200 rpm
Sienna	189 hp at 6,000 rpm	176 lb-ft at 4,400 rpm
Highlander Hybrid	186 hp at 6,000 rpm	175 lb-ft at 4,400 rpm
Grand Highlander Hybrid	187 hp at 6,000 rpm	-

Frequently Asked Questions

In Toyota's hybrid system, the 2.5-liter gas engine works together with electric motor power in each of the seven 2026 models that use it. The RAV4 Hybrid's front electric motor, for example, drives the front wheels and recovers energy when you brake, and its all-wheel-drive versions add a separate rear electric motor. In the Camry, Crown Signia, Grand Highlander Hybrid, Highlander Hybrid, RAV4 Hybrid and Sienna, the transmission is an electronically controlled continuously variable transmission (ECVT). Models with an EV mode, such as the Camry and RAV4 Hybrid, can also run on battery power alone for short distances at low speeds, in limited circumstances.

Seven 2026 models use it: the Camry, RAV4 Hybrid, Crown (XLE, Limited and Nightshade grades), Crown Signia, Highlander Hybrid, Grand Highlander Hybrid and Sienna. Every 2026 Camry and every 2026 Sienna is a hybrid. The 2026 Crown Platinum and the 2026 Grand Highlander Hybrid MAX use a 2.4-liter turbocharged four-cylinder instead.

For the 2026 models, Toyota's net system ratings run from 225 hp in the front-wheel-drive Camry to 245 hp in the Sienna and Grand Highlander Hybrid. On its own, the engine is rated from 183 hp for the RAV4 Hybrid to 189 hp for the Sienna. The net rating is Toyota's figure for the whole hybrid system, so it is not the engine and motor ratings added up.

Among the seven 2026 2.5-liter hybrids, EPA combined ratings run from a high of 51 mpg in the front-wheel-drive Camry LE to a low of 34 mpg in the all-wheel-drive Grand Highlander Hybrid. Within the 2026 RAV4 Hybrid lineup, front-wheel drive rates highest at 43 mpg combined and the Woodland Edition lowest at 38.

It can. For 2026, all-wheel drive raises Toyota's net rating for the Camry from 225 to 232 hp and for the RAV4 Hybrid from 226 to 236 hp. The Sienna keeps 245 hp either way, and so does the Grand Highlander Hybrid. EPA combined ratings dip with all-wheel drive in several of these models: the Camry LE goes from 51 to 50 mpg, the Sienna from 36 to 35 and the Grand Highlander Hybrid from 36 to 34.

Yes, within limits. The 2026 Camry, Crown, Crown Signia and RAV4 Hybrid have an EV mode that lets you drive solely on battery power at low speeds, for short distances and in limited circumstances, such as in a parking garage. Some conditions may prevent or limit its use, and your Owner's Manual explains how to use it and its limits.

Hybrid MAX uses a 2.4-liter turbocharged four-cylinder in place of the 2.5-liter. For 2026, Toyota rates the Crown Platinum's Hybrid MAX at 340 net hp, compared with 236 hp for the 2.5-liter Crown grades. The Grand Highlander's Hybrid MAX is rated at 362 net hp, against 245 hp for the 2.5-liter Grand Highlander Hybrid.

No. The 2026 Corolla Hybrid uses a 1.8-liter four-cylinder, and the 2026 Prius and Corolla Cross Hybrid use a 2.0-liter four-cylinder.
