INTRODUCTION
The LEVC TX 1.5 Range Extender, launched in 2017, is a purpose-built vehicle primarily aimed at the professional driver market, particularly in densely populated urban environments. It represents a significant departure from traditional taxi designs, embracing a fully electric drivetrain supplemented by a small gasoline engine to extend its range. Built on a new aluminum-intensive platform, the TX is designed to meet increasingly stringent emissions regulations while providing a comfortable and practical experience for both drivers and passengers. The vehicle is a key component of LEVC’s strategy to become a leading provider of sustainable urban transportation solutions. It’s a rear-wheel drive vehicle, utilizing a single-speed automatic transmission.
Powertrain & Engine Architecture
At the heart of the TX 1.5 is a sophisticated PHEV system. The primary source of propulsion is a rear-mounted electric motor producing 150 horsepower and 250 Nm (184 lb-ft) of torque. This motor draws power from a 31 kWh lithium-ion battery pack located under the floor and front seats, providing an all-electric range of up to 103 km (64 miles) WLTP. When the battery is depleted, a 1.5-liter, three-cylinder turbocharged gasoline engine (code B3154T) kicks in as a range extender. This engine produces 91 horsepower and 160 Nm (118 lb-ft) of torque. It doesn’t directly drive the wheels; instead, it powers a generator to recharge the battery, allowing for a total range of over 600 km (373 miles). The engine features direct injection and a DOHC valvetrain. The single-speed automatic transmission is specifically designed for the electric motor, providing smooth and seamless acceleration.
Driving Characteristics
The TX 1.5 offers a distinctly different driving experience compared to conventional vehicles. In all-electric mode, it provides near-silent operation and instant torque, making it ideal for navigating congested city streets. Acceleration is adequate, with a 0-60 mph time of around 12.5 seconds, but it’s not designed for sporty performance. When the range extender engages, the engine noise is noticeable, but it’s generally well-insulated from the cabin. The single-speed transmission simplifies the driving experience, but it also means there’s no gear shifting to optimize power delivery. Compared to potential higher-output versions (which were never offered), this 150 hp configuration prioritizes efficiency and range over outright speed. The rear-wheel drive configuration contributes to a stable and predictable handling characteristic.
Equipment & Trim Levels
The TX 1.5 is primarily offered with a focus on practicality and passenger comfort. Standard features include air conditioning, power windows, central locking, and a user-friendly infotainment system with navigation. The interior is designed to be durable and easy to clean, with seating for up to six or seven passengers depending on the configuration. Optional extras include upgraded upholstery, premium audio systems, and advanced driver-assistance features such as lane departure warning and autonomous emergency braking. The trim level is relatively standardized, reflecting the vehicle’s primary use as a commercial vehicle. However, LEVC offers customization options to meet the specific needs of fleet operators.
Chassis & Braking
The TX 1.5 features a robust chassis designed to withstand the demands of continuous urban operation. It utilizes an independent McPherson strut suspension at the front and an independent multi-link suspension with a leaf spring at the rear. This setup provides a comfortable ride quality while maintaining good handling characteristics. The vehicle is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. An Anti-lock Braking System (ABS) is standard, enhancing safety and control. The relatively high kerb weight (2144-2305 kg) necessitates a strong braking system.
Market Reception & Comparison
The LEVC TX 1.5 has been generally well-received by critics and operators, particularly in London where it has become the dominant taxi model. Its low emissions and all-electric range have made it a popular choice for drivers seeking to comply with increasingly strict environmental regulations. Compared to older diesel-powered taxis, the TX offers significantly improved air quality and reduced running costs. While the initial purchase price is higher, the lower fuel and maintenance costs can offset this over the vehicle’s lifespan. Compared to other PHEV options, the TX stands out due to its unique design and purpose-built nature. Its fuel economy of 0.8 l/100km (WLTP) and low CO2 emissions of 19 g/km are highly competitive.
Legacy
The LEVC TX 1.5 represents a pivotal moment in the company’s history, marking its transition from a manufacturer of traditional taxis to a provider of sustainable urban mobility solutions. The powertrain, while not without its complexities, has proven to be relatively reliable in real-world operation. The vehicle’s long-term durability will depend on factors such as battery health and maintenance practices. On the used car market, the TX 1.5 is gaining traction as a viable option for environmentally conscious buyers and those seeking a unique and practical vehicle. Its innovative design and commitment to sustainability are likely to ensure its place in automotive history.
