SEM is the name by which the all-electric platform adopted by many cars of the Volkswagen Groupoffered on the market with i Skoda, Audi, Seat and Volkswagen brands. This modular platform is based on an engine positioned at the rear and traction on this axle, without prejudice to the possibility of installing a second front engine that transmits the movement to the front wheels, making the car four-wheeled driving.
In the current implementation, the MEB platform can accommodate a maximum of one battery pack with a capacity of 82 kWh.a value which makes it possible to obtain a maximum autonomy which varies according to the vehicle and the number of engines but which can be quantified around 500-550 km in the WLTP cycle.
However, the group’s future plans include the adoption of higher capacity batteries., still hosted on the MEB platform. Volkswagen did not give specific details but said a range of up to 700 km. Data of this type leads to the hypothesis of a capacity just over 110kWhbattery that could be used in vehicles of the group with dimensions greater than, for example, ID.4.
This will not be the only novelty of the group’s electric platform: the maximum power accepted under load will increaseat the moment it is fixed at 125kW and which should obviously exceed 200kW with charging solutions capable of providing this power. Performance will also benefit, with an acceleration time from 0 to 100Km/h that will reach 5.5 seconds in the AWD versions equipped with twin motors. With the added weight given by the larger battery, it’s easy to imagine that the increased performance will be achieved by engines with more power than the 299 hp of the current AWD versions of the Audi Q4 E-Tron and Volkswagen ID.4 .
