What is the gap between ideal and mass production
The transfer chain cut off the space and came out
The conventional fuel undercarriage must be fully equipped with a mixer, a transformer, a transfer axis, a speed differential, and a split, with an additional 40 kg of weight and regular oil replacement. The rotor plugs the drive unit directly into the circle, the transmission chain is cut off, the chassis space is empty and the short axle-range vehicle can be plugged into a large-capacity battery bag。
In 2024, data from the pure power platforms published by several of the country's front companies showed an average reduction of 8 to 12 kg in the overall mass of the vehicle after the removal of the transmission axes and differentials, a drive efficiency of more than 95 per cent from the conventional programme and a high-speed cruise of 0. 3 to 0. 5 degrees of electricity per 100 km of energy consumption。
We can all play around
Each wheel is equipped with a stand-alone electric generator, and a full-time round-trip front- and back-drive is a matter of switching the control signal at no additional cost to the hardware. The right and right wheel speeds vary, or even reverse, so that the vehicle can move like a tracked car, turning in situ at the limit and turning the radius close to zero。
In 2025, one of the country's special vehicle enterprises displayed a roulette undercarriage sample, with a rotation radius of less than 1. 5 metres in situ, nearly half the size of the fuel vehicle of the same grade. The cost, however, is that the tyre side of the turn-over is very slippery, with the wear and tear cycle contracting from the conventional 80,000 km to around 30,000 km, which is difficult for ordinary passenger users to accept in the long term。
Three new energy routes are directly connected
Pure electric power, fuel cells, add-ons, the main drive with the wheel-wire power, is all right, and the electric power itself deals with electricity and saves all the troubles with gearbox matching. It can also be used as a start-up and accelerator auxiliary power plant in a mixing programme, where two generators plus motors are used。
The regenerative brakes automatically cut the power mode as soon as the turbine brakes were set, and the kinetic energy returned directly to the battery pack, which was more efficient than the conventional option. In 2024, three new energy companies in the country reported an average of about 2 additional degrees per 100 km of power recovered from a wheeled motor vehicle, resulting in an additional 10 to 12 kilometres of flight。
It's a lot of manipulation
The engine is loaded into a circle with an additional 10 to 15 kg of spring mass, the speed of the response is slowed visiblely, and the sense of car invertion is even more evident when the speed belt and pits are down. Aluminium alloy arms, light quantitative control arms, conventional weight reduction methods that do not contain the weight of the electric power plant, are effectively reducing the limits of manipulation。
For the time being, the city's motor vehicle users have been able to stand up to this short panel, and after all, daily commuting is not very much a matter of maximum control. However, the performance vehicle did not work, and in 2025, at a domestic test site, when the motor model was converted at high speed, it was almost three centimetres larger on the side than a fuel car of the same grade, and more traffic patterns made it impossible to catch up to the road。
Brake and heat spread are all hard bones
The engine's own electric brake capacity does not support the entire brake requirement and an additional mechanical brake system must be installed. The electric vehicle was free of engine-driven vacuum pumps and had to use the electric vacuum pump to support the brakes, which was more energy-intensive. The energy recovered from the regenerative brakes is not consumed, and the brake system becomes the back leg of the towing。
Seal and heat dispersion are more difficult to bypass, electrics are bubbled in the wheel, mud and dust are drilled into the cracks, the ip67 protection level is the bottom line, and the dissipation requires a separate exclusive channel. In 2024, domestic manufacturers dropped the output twister by more than 20 per cent after two hours of continuous load in the salt fog and high temperature cycle test, and the dissipation programme largely reversed。
The delivery window is the year after tomorrow
The technology is in the right direction, but the long-term reliability of the seal, the balance between the start-up large electrical current and the peak twist, and the differential control at the speed of the high-speed shift have not yet been fully eaten off. In 2025, the number of hands on the brand of a vehicle that actually produces a wheeled motor in real quantities in the country was reached, and most projects were in the demonstration operation and small batch phases。
However, the country’s motor power plant has been active in recent years, with the construction of production lines in suzhou, changzhou and wuhan, and the head enterprise’s capacity is planned to exceed millions by 2027. New energy vehicle holdings are continuing to rise, and the production window is likely to fall behind around 2028 when road survey data are accumulated。
