Parameter analysis of Tucki MONA M03 part of rear-drive hatchback coupe.

On July 3rd, Tucki MONA M03 was officially released, but this time only the appearance of the new car was released, but there was no interior information.

Tucki MONA M03 is a pure electric hatchback car with a size of 4780x1896x1445mm and a wheelbase of 2815mm, which is similar to that of BYD Qin L, and its level is between compact and medium-sized cars (A+ class), focusing on the market of 100,000-150,000 yuan. Booking will be started from now on and it will be officially launched in August.

▍On the "second in the world" wind resistance of 0.194

The wind resistance coefficient CD of MONA M03 in Tucki is 0.194, and the maximum cruising range of CLTC reaches 620km.

0.194 is the second lowest wind resistance of mass production cars in the world at present, surpassing 0.195 of Xiaomi SU7, but losing to 0.1925 of Extremely Fox Alfa S5.

It is worth mentioning that the drag coefficient value of 0.194 runs out at 160km/h (the test conditions are consistent with SU7).

Although the wind resistance test conditions of Extreme Fox Alpha S5 can’t be checked for the time being, it may be consistent with the test conditions of SU7 and Tucki M03.

Extremely low drag coefficient means better energy efficiency. In the case of limited cost, it is the most effective way to optimize the body structure if the hatchback car of 100,000-150,000 class wants to dig out more endurance.

It is worth mentioning that Tucki MONA M03 adopts 400V high-voltage platform, but its battery supplier is from Foday Battery, which is BYD, so its battery reliability is still very guaranteed.

▍Front McPherson, rear torsion beam+rear motor, rear wheel drive

Regarding the chassis and power parameters of the vehicle, this conference mentioned very little.

As a 100,000-150,000-class pure electric car, Tucki MONA M03 is equipped with front McPherson and rear torsion beam suspension, which is really not amazing, and even the rear torsion beam suspension will put a question mark on the rear comfort of the vehicle.

Besides, what was the last car in Tucki with a front McPherson and a rear torsion beam?

Yes, it’s Tucki P5.

Therefore, Tucki MONA M03′ s first impression on suspension is not good.

In addition, MONA M03 in Tucki only provides 18-inch and 19-inch rims, especially its 19-inch rim, and the flatness ratio is only 40(235/40 R19), which brings great challenges to the rear seat comfort of M03.

However, interestingly, according to the information, Tucki MONA M03 is a set.Rear drive carThe low-power version and the high-power version are equipped with 140kW Suzhou Huichuan Motor and 160kW Fisch Green Energy Motor respectively.

Then the question is coming-where should the Tucki MONA M03 rear motor be placed?

As we know, the rear suspension structure of pure trams with rear drive is generally in the form of rear five-bar linkage, because compared with the traditional E-type four-bar linkage, the rear five-bar linkage not only has more adjustment dimensions and stability, but also takes up more space for arranging rear motors.

Simply put, the rear motor can be placed in the middle of the suspension, that is, in the rear subframe (the picture above shows the schematic diagram of Volkswagen MEB chassis).

However, the rear torsion beam suspension of MONA M03 in Tucki, as a suspension that runs through the whole underbody of the vehicle, puts forward new requirements for the layout of the rear motor. Generally speaking, the most likely place to place the rear motor is directly above the rear torsion beam suspension. However, will the storage space of M03 be affected by this arrangement?

However, according to the official parameters, the trunk volume of MONA M03 in Tucki is 621L, and there are additional storage compartments under the trunk partition.

It seems that Tucki has made efforts to solve the interference problem between the rear suspension and the rear drive motor.

▍End: Besides intelligent driving, what is the "killer weapon" of Tucki M03?

In other aspects of the new car, except that the interior has not been announced, we should have seen a number of cameras mounted on the M03 in Tucki. It is expected that the full-roof model will be equipped with about 11 cameras to achieve a full-vision intelligent driving scheme.

If Tucki M03 can have the NOA function similar to XNGP, it will also become a major selling point of M03. However, in addition to smart driving, consumers with the price of 100,000-150,000 pay more attention to some basic skills as a "car", such as appearance, interior, comfort, driving control and so on.

In this respect, M03′ s opponent is obviously not Tesla, but BYD.
