Innovative design for superior handling
Harbinger's EV delivery trucks feature a unique chassis design that places the heavy battery within the frame, resulting in a significantly lower center of gravity compared to traditional medium-duty trucks. This innovative layout allows for powerful torque and superior handling, even for vehicles over 13 feet long. The result is a truck that handles more like a passenger car, even in harsh winter conditions.

tough winter test
The winter testing program in New Zealand focused on several key aspects.
Brake system: Harbinger thoroughly tested the truck's entire braking system, including traction control, stability control, ABS, and regenerative braking.

Automatic hill hold: This feature prevents the vehicle from rolling backwards (or forwards) when stopped on a slope, and Harbinger tested it in low-traction conditions of ice and snow. This feature is common in passenger cars, but Harbinger brings it new to medium-duty trucks.
Edge case: Approximately 80% of the tests conducted were designed around 5% of use cases, ensuring that the vehicle can cope with even the most extreme conditions.

Key elements of winter testing
According to Harbinger co-founder and CEO John Harris, winter testing is critical to vehicle development, especially EV development. It ensures that the vehicle performs well even on low-traction surfaces such as ice and snow. The focus is on typical cold-weather driving conditions, as well as less common but important and high-risk scenarios. This is especially important for EVs with high torque outputs, which can lead to loss of control if not managed correctly on slippery roads. Systems such as regenerative braking also need to be optimized for extreme conditions.

Special tests for driver safety
Some tests can only be conducted in real winter weather to provide stress testing to optimize driver safety.
Low adhesion surface control: Ensures vehicle maneuverability and stability even on snow and ice.
Traction and stability testing: Verify traction control and stability systems during hard acceleration, braking, and cornering.
Regenerative braking on slippery roads: Test how regenerative braking interacts in low traction conditions to prevent skidding.
These tests help ensure that the vehicle can safely handle extreme weather conditions, such as when a driver hits a patch of slippery black ice and has to stop steering or accelerate.

Battery performance in winter conditions
According to Harbinger, all battery-powered vehicles face challenges in cold climates due to two main factors: reduced battery performance and increased energy consumption for cabin heating. Cold temperatures slow down the chemical reactions within the battery, leading to reduced efficiency and power output. Additionally, electric cars require energy to heat the interior of the vehicle, further reducing their range. Harbinger addresses these concerns by utilizing a multi-zone heat pump that efficiently provides heating to both the battery and the cabin, thereby minimizing the negative impact of cold weather on performance.

Charging at low temperatures
Charging an electric car in cold weather is usually not a problem. Harbinger delivery trucks can safely charge in cold temperatures, allowing drivers to maintain uninterrupted operations. It's important to note that charging times can take longer when your battery is cold, but Harbinger alleviates this inconvenience by adjusting your battery to the perfect temperature for charging even when it's cold outside. .
