The ZGH Group held a briefing in Malaysia for the local media, where its chief engineer Kent Bovellan spoke about the modular architecture of SEA (Sustainable Experience Architecture). It turned out that five platforms have been developed: SEA1 (for large models of segments D, E, F), SEA2 (for classes from B to D), SEA-E (aka SEA Entry, for state employees of the A-segment), SEA-S ( SEA Sport for sports cars) and SEA-C (SEA Commercial for vans, vans and pickups). All platforms have a number of common components, so a combination of “carts” is possible. It is possible to replace them with some others.
The smallest SEA model in development has a wheelbase of 2,550 mm. Therefore, there is no need to wait for tiny electric cars and ATVs (a la Citroen Ami) on the SEA-E “cart”. Meanwhile, the SEA-S sports platform is directly compared to the PPE from Audi and Porsche.
Swede Bovellan, who previously worked at Volvo, recalled that now only SEA1 is in use, which is used by the five-door Zeekr 001, but a number of new models are on the way. Obviously, we are talking about the conditional Volvo XC20 and the Smart crossover, which will debut in the fall.
Universal SEA supports front, rear and all wheel drive. The power of the power plants is limited at around 600 kW (816 hp, 8000 Nm). The bar in acceleration to hundreds – 2.8 s. The capacity of CATL batteries ranges from 58 to 110 kWh. The cruising range is estimated at 460-700 km (NEDC), but 1000 km is possible with an additional generator. The operating voltage of 400-800 volts allows you to hope to charge up to 80% in 20-30 minutes. Bovellan said SEA platforms will outperform Tesla’s carts in all areas except performance.
