Subaru Solterra 2023-2026 Owner's Manual: Battery Electric Vehicle driving tips

When operating the Subaru Solterra, it is important to understand that battery electric vehicles behave differently from conventional gasoline-powered cars. At sustained high speeds—such as on highways or freeways—the efficiency of electricity consumption decreases, which can significantly reduce the estimated driving range. For this reason, if the traction battery level in your Subaru Solterra is low, avoid relying solely on the displayed remaining range and minimize extended high-speed driving whenever possible.

The following practical driving recommendations for the Subaru Solterra will help reduce energy consumption and maximize available driving distance.

Shift position operation

When driving the Subaru Solterra, keep the shift position in D during normal driving conditions, such as when waiting at traffic lights or moving through heavy traffic. Always shift to P when parking the vehicle.

Switching to N while driving does not provide any benefit in terms of energy efficiency. In fact, in the Subaru Solterra, regenerative charging is disabled in N mode, and electrical systems such as air conditioning will continue to consume battery power without replenishment.

Delays

Frequent acceleration and deceleration caused by traffic congestion, long stops at intersections, or driving on steep inclines can significantly increase energy consumption in the Subaru Solterra.

To minimize this effect, plan your route in advance and check traffic conditions before departure. When driving in congested traffic, gently release the brake pedal to allow smooth forward movement and avoid aggressive acceleration. This driving style helps conserve battery energy and improves efficiency.

When braking

Use the braking system of the Subaru Solterra smoothly and in a controlled manner. Gentle braking allows the regenerative braking system to recover more kinetic energy and convert it into usable electricity stored in the traction battery.

Highway (or freeways) driving

While driving the Subaru Solterra on highways, aim to maintain a constant speed to optimize efficiency. Anticipate stops—such as toll booths or traffic slowdowns—by releasing the accelerator early and applying the brakes gradually. This approach maximizes energy recovery through regenerative braking.

Air conditioning

• Operate the air conditioning system in the Subaru Solterra only when necessary, as excessive use can increase energy consumption and reduce driving range.

In summer: When outside temperatures are high, use recirculation mode to reduce the workload on the cooling system and improve efficiency.

In winter: Avoid excessive heating whenever possible. Limiting heater usage in the Subaru Solterra helps conserve battery energy.

Energy efficiency can also be improved by using alternative heating methods, such as seat heaters, instead of relying solely on cabin heating.

• When the ALL AUTO (ECO) mode is activated, the Subaru Solterra prioritizes energy-efficient heating methods like seat heaters, reducing the load on the climate control system.
• Using the Remote Air Conditioning System while the vehicle is connected to an AC charging cable allows the Subaru Solterra to pre-condition the cabin using external power, reducing battery consumption once driving begins.

Checking tire inflation pressure

Regularly check and maintain proper tire inflation pressure on your Subaru Solterra.

Incorrect tire pressure can increase rolling resistance, leading to reduced efficiency and higher energy consumption.

Additionally, using winter tires on dry roads can increase friction and negatively impact energy efficiency. Always choose tires appropriate for the current season.

Luggage

Excess weight has a direct impact on the energy efficiency of the Subaru Solterra.

Carrying unnecessary cargo increases power consumption and reduces the driving range, so it is advisable to keep the vehicle as light as possible for optimal performance.

By adopting these efficient driving habits, Subaru Solterra owners can significantly extend battery range, improve overall performance, and enjoy a smoother, more economical electric driving experience.
