At last. Gearbox in a EV as i predicted. Range doubled to over 700 km . And that is only two ratios.

If there is a four speed gearbox, who knows. 2000 km range?

EV have high torque. No need for powerful motor. What you need is a gearbox.

Mercedes-Benz has provided early details of the powertrains that will be offered for the third-generation CLA, which is set to be the first model to be built on the Mercedes-Benz Modular Architecture (MMA). The skateboard platform will also be used for three other cars, including a shooting brake and two SUVs.

According to the German carmaker, the CLA will be available as pure electric vehicle (EV) which uses its new-generation Electric Drive Unit (EDU 2.0). This sees a rear-wheel drive layout that was typically reserved for vehicles higher up the class tree, with electric motor rated at 272 PS (268 hp or 200 kW).

All power electronics, including a silicon carbide (SiC) inverter are integrated into a single component to keep things compact. For even better efficiency, the rear EDU 2.0 unit also gets a two-speed transmission, which is not common among EVs that typically opt for a single-speed reduction gear.

The transmission’s first gear (11:1 ratio) is used when accelerating from a standstill and switches to the second gear (5:1 ratio) at higher speeds, with the top speed being 210 km/h. The shift points also take in account the driving situation and the selected driving programme.

To meet the needs of customers who require all-wheel drive, 4Matic variants of the upcoming CLA will add a front-mounted electric motor (with a single-speed reduction gear) providing 109 PS (107 hp or 80 kW). This won’t be active all the time and will only kick into action when the corresponding power or traction is requiredrequired.

To achieve this, a Disconnect Unit (DCU) is used for the first time for the brand’s entry-level segment to decouple the electric motor on the front axle. Mercedes-Benz says this reduces front axles losses by 90% and helps to increase range, with the target being a WLTP-rated figure of 750 km as per the Concept CLA Class from a year ago. The compact front unit also allows for a frunk.
 
Your engineering understanding is bad. Torque has nothing to do with range. Only battery capacity, motor efficiency, drag coefficient determines range, everything else being equal.

So installing a gearbox with more gears does nothing for range but reduces the motor whine while accelerating.

You attended Malay school, that's why like this.
