In terms of the initial burst force of torque output, the gas utility mini bike equipped with a small internal combustion engine usually shows a significant advantage. Its peak torque can reach 40 Nm, and it can instantly release 95% of the torque when the rotational speed reaches 3000 RPM. Compared with electric models of the same specification on the market, the median peak torque of this model is approximately 35 Nm. Although the response time of the electric motor is only 100 milliseconds, which is 300% faster than that of the fuel engine, the torque curve of the gas engine is more gentle when the load suddenly increases, with a fluctuation rate of less than 5%. For instance, an independent assessment of North American utility companies in 2023 revealed that when towing a 150-kilogram load up a 15-degree slope, gas-powered vehicles achieved a success rate of 98%, while electric vehicles performed at 92% in the same test.
However, the assessment of torque performance must be combined with the working cycle and temperature variables. In an extremely cold environment of minus 10 degrees Celsius, the torque output of a gas engine only decreases by approximately 8%, while under the same conditions, lithium batteries may experience a reduction of up to 25% in torque output due to a decrease in capacity and discharge efficiency. Referring to the report of a certain technical research institute in Germany in 2024, a typical gas utility mini bike controlled the deviation range of torque stability within ± 3% during a continuous 4-hour heavy-load operation. However, for electric vehicles under the same duration of high-load, due to the accumulation of battery heat and voltage drop, The torque output may show a periodic attenuation of 15%. This feature makes gas vehicles more reliable in long-term tasks such as emergency maintenance in winter.
From the perspective of full life cycle cost analysis, the torque advantage needs to be balanced with the operating budget. The purchase price of a gas-powered mini bicycle is approximately 70% of that of an electric model, but its fuel cost may be 40% higher over a five-year usage period. If calculated in terms of the cost per unit of Newton-meter of torque output, gas-powered vehicles lead in the initial return on investment, with the acquisition cost of each 1 Newton-meter of torque being 20% lower than that of electric vehicles. As recorded in the procurement assessment of a certain Asian energy company in 2022, they chose gas models for their mountain inspection fleet precisely because they could still maintain 90% of the rated torque in high-altitude and low-oxygen environments, while the torque attenuation rate of electric motors exceeded 18% at altitudes above 3,000 meters.
Future trends indicate that technological innovation is changing the competitive landscape. The new gas engine can increase the torque density to 90 Newton-meters per liter of displacement through turbocharging technology. Meanwhile, the breakthrough in the magnet material of the electric motor has also enabled its maximum torque output to increase at an annual growth rate of 5%. A market forecast for 2025 indicates that in the public utility sector, the torque performance gap between gas and electric vehicle models will narrow to within 10% over the next decade. However, in terms of current application scenarios, for those areas that require continuous fieldwork for more than 72 hours and lack charging infrastructure, the torque reliability and energy replenishment speed (3 minutes of refueling compared to 2 hours of charging) of the gas utility mini bike are still decisive advantages. This has been verified many times in critical tasks such as emergency response to natural disasters.
