The Toyota RAV4 “EV” Mode Explained (Prime vs. Hybrid)

Both the Toyota RAV4 Prime and RAV4 Hybrid have an EV mode meant to increase efficiency. Between the two models, the RAV4 EV mode works differently, so it’s important to understand the distinctions. I show the differences, explain how each works and give some helpful tips.

It doesn’t take long to see that the RAV4 Hybrid EV mode isn’t nearly as capable as the Prime.

Toyota RAV4 Prime vs. Hybrid “EV” Modes (An Important Distinction)

The Toyota RAV4 is available as both a Prime plug-in hybrid and Hybrid configuration. While they are similar, there is one big difference between the two. The RAV4 Prime is the plug-in hybrid model. It gets plugged in to charge and contains a larger battery capacity than the Hybrid.

The Toyota RAV4 Hybrid doesn’t get plugged in. It charges over time with the help of regenerative braking and the gas engine. It also includes a smaller electric battery than the Prime, thereby decreasing the driving range significantly.

While both RAV4 models have an EV button, it behaves much differently. The RAV4 Prime operates more like an electric vehicle because of the plug-in design. To understand the differences, read on for more information.

Toyota RAV4 Prime EV Mode

The RAV4 Prime debuted in the United States at the 2019 Los Angeles Auto Show. Sales started as a 2021 model. The RAV4 Prime EV mode is just one major feature that sets this plug-in hybrid electric vehicle (PHEV) apart.

How EV Mode Works in the RAV4 Prime

When the EV mode is engaged on the RAV4 Prime, it allows for electric-only driving. The electric motor takes over, circumventing the gas engine.

EV driving is easily canceled. When it cancels, the gas engine and electric motor get used together again. If EV driving becomes possible again, it will revert back to the EV mode.

These circumstances cause EV mode to be canceled automatically.

• If the vehicle speed exceeds about 84 mph (135 km/h).
• When power is needed temporarily. If you press the accelerator pedal firmly or attempt to accelerate quickly.
• If the hybrid system temperature exceeds normal parameters. This occurs when the vehicle is parked in the sun, driven at higher speeds, climbing a steep incline, etc.
• If the hybrid system temperature doesn’t hit minimal requirements.
• When the cabin heater is in use with outside temperatures below around 14°F (-10°C).
• If the windshield defogger switch is on.
• When the system determines the gas engine is needed.

RAV4 Prime EV Mode Range

The Toyota RAV4 EV mode range is up to 42 miles with the Prime model. Once the battery drains, the gas engine automatically kicks in.

The EV range can be shorter than expected if the car is driven aggressively. It also decreases when driving up hills or an abundance of accessories is used.

On the other hand, the EV range can exceed 42 miles when driving downhill because of regenerative braking. This advanced system recharges the battery and eases the burden on the electric motor.

Tips for Using EV Mode on the RAV4 Prime

It’s easy to maximize the performance of the EV mode on the Prime. Follow these helpful tips.

• Avoid sudden acceleration or deceleration. Drive as smoothly as possible to keep the battery at maximum capacity. EV mode automatically cancels if acceleration occurs too fast.
• Maintain adequate speeds. EV mode works most efficiently at normal speeds.

It does take some practice to get used to maximizing the EV range. After a few times, you gain a better feel for how to make the most of the drive.

Toyota RAV4 Hybrid EV Mode

In 2019, Toyota also released the RAV4 Hybrid model. With standard four-wheel drive and a 1.6 kWh nickel-metal-hydride battery, it’s been a top choice for fuel efficiency. Learning how to use the RAV4 Hybrid EV mode helps to enhance the ride.

How EV Mode Works on the RAV4 Hybrid

The EV mode on the RAV4 Hybrid is much different than the Prime. When using the EV drive mode, electric power gets supplied by the hybrid battery, known as the traction battery. The electric motor or traction motor drives the vehicle.

The benefits of the RAV4 Hybrid EV mode are different because the battery has minimal capacity. The EV mode system also only works up to about 25 mph for short distances.

It’s beneficial when noise or gas emissions are a concern. EV mode can be used to navigate a residential area early in the morning or late at night without disturbing anyone. It’s also helpful when driving through an indoor parking lot or garage to prevent trapping the exhaust gases in an enclosed space.

Still, the RAV4 Hybrid may still produce sound when the vehicle proximity notification system is activated.

The EV drive mode may be inoperable in these conditions:

• The hybrid system temperature is too high. Temperatures rise when parked in the sun, driving up hills or traveling at high speeds.
• The hybrid system temperature is too low. Temperatures drop when parked for an extended period in weather of about 32°F (0°C) or lower.
• The gas engine hasn’t warmed up yet.
• The hybrid (traction) battery is low. This measurement is displayed on the Energy Monitor.
• Speeds of the RAV4 Hybrid exceed about 25 mph.
• The accelerator pedal is pressed firmly.
• If the vehicle is climbing a hill.
• The windshield defogger is on.

When the EV mode cannot be turned on or cancels, a buzzer sounds. There’s also a message displayed on the multi-information center.

RAV4 Hybrid EV Mode Range

The RAV4 Hybrid EV mode range is much shorter than the Prime. EV mode can drive between a few hundred meters to about 0.6 miles (1 km).

Using the EV mode depends on whether the battery is charged. It is also dependent on the circumstances listed above that deactivate the functionality.

Tips for Using EV Mode on the RAV4 Hybrid

Before using the EV mode, here are a few helpful tips to consider.

• This mode is best used when driving in residential areas during quiet times.
• Use this mode in indoor parking lots where noise and gas emissions matter.
• When you need the gas engine is needed again, press the EV mode button again to cancel it.

Honestly, the EV mode on the RAV4 Hybrid is mostly a gimmick. It doesn’t last long and only reduces noise for a short time. Most people feel the RAV4 gas engine is quiet enough on its own that this mode isn’t needed.

Frequently Asked Questions About the RAV4’s EV Mode

Getting the Most Out of RAV4 EV Mode

While both the RAV4 Prime and Hybrid models have the EV mode, there’s clearly a difference between the two. When driving a RAV4 Prime, electric driving is possible for around 42 miles in perfect conditions. The RAV4 Hybrid can’t boast of that capability, making the EV mode less valuable.

Understanding how to use the Toyota EV mode makes a difference in noise and emission pollution. Before heading out on a daily commute, it’s helpful to review the tips outlined above.
