CES in Las Vegas has become a fashionable place for automakers to show off high-tech vehicles in recent years. At CES 2022, semi-truck maker Kenworth showcased the new electric big rig called the T680E. With the vast distances the typical semi-truck covers each day, the T680E certainly isn’t appropriate for most long-haul trucking scenarios. However, it represents a significant step forward in the electrification of commercial vehicles.
Specifications and Performance
Kenworth says the T680E has a driving range of 150 miles depending on the application. It is a Class 8 vehicle with an 82,000 pounds gross vehicle weight rating. The electric powertrain has 536 continuous horsepower and 670 peak horsepower. This makes it suitable for a variety of short-haul and regional delivery applications where the range is less of an issue.
The electric powertrain produces 1623 pound-foot of torque, providing ample power for heavy loads. Top speed is limited to 65 mph, which is common for semi-trucks to ensure safety and fuel efficiency. The vehicle can utilize charging systems with output ranging from 20 kilowatts to 350 kilowatts, allowing for flexible charging options depending on the infrastructure available.
Environmental Impact and Cost Considerations
One of the most significant advantages of the T680E is its zero-emissions operation. As regulations around emissions become stricter, electric trucks like the T680E offer a way for companies to comply with new laws and reduce their carbon footprint. This is particularly important in urban areas where air quality is a major concern.
It’s unclear how much the electric semi-truck costs, but keep in mind a traditional diesel-powered big rig can cost well over $160,000. While the initial investment in an electric truck may be higher, the lower operating costs and potential incentives for zero-emission vehicles could make it a more economical choice in the long run. Electric trucks have fewer moving parts than their diesel counterparts, which can result in lower maintenance costs. Additionally, the cost of electricity is generally lower and more stable compared to diesel fuel.
Challenges and Future Prospects
Despite its advantages, the T680E faces several challenges. The limited range of 150 miles means it is not suitable for long-haul routes, which make up a significant portion of the trucking industry. However, for short-haul and regional routes, the T680E could be an excellent option. Infrastructure is another challenge; widespread adoption of electric trucks will require significant investment in charging stations, particularly high-capacity ones that can handle the needs of large commercial vehicles.
Another consideration is the time required for charging. While the T680E can utilize fast-charging systems, the time it takes to recharge compared to refueling a diesel truck can be a drawback. Companies will need to plan their routes and schedules carefully to accommodate charging times.
The Kenworth T680E represents a significant step forward in the electrification of commercial vehicles. While it may not be suitable for all trucking scenarios, its zero-emissions operation, lower operating costs, and suitability for short-haul routes make it a promising option for the future. As technology advances and infrastructure improves, electric trucks like the T680E could become a common sight on our roads, contributing to a cleaner and more sustainable transportation industry.
