Geely refers the SEA platform as "open-source," meaning the manufacturer is open to supply the platform to other automakers.[2] Geely Holding has claimed it has entered into preliminary discussions with other manufacturers about potential use of the SEA platform.[3]

Overview

The SEA platform is more of an architecture that unifies multiple platforms covering almost all vehicle types. The platform will consist of five different core versions covering a variety of market segments:[4]

  • SEA1 for large vehicles covering segments D (mid-size) to F (luxury)
  • SEA2 for B-segment to D-segment
  • SEA-E (SEA Entry) for A-segment and budget vehicles
  • SEA-S (SEA Sport) for sports models
  • SEA-C (SEA Commercial) for vehicles between 3.5 and 5.5 tonnes, including trucks, vans, and buses.

Each core platform will further be available in several different variants such as front, rear, and all-wheel drive, as well as single, double, and triple motor configurations.[5] Performance is expected to be competitive, with support for both 400V and 800V architectures, fast charging, and 0-60 acceleration times as low as three seconds.[6]

The predecessor of SEA platform is Geely's pure electric vehicle platform PMA. According to Geely's plan for the SEA architecture, the PMA platform was split into two variants in the later phase with the PMA-1, now renamed SEA-1, used in medium and large vehicles such as the Zeekr 001, and PMA-2, now renamed SEA-2, used in small and compact vehicles such as Smart #1.[7]

The first model based on the SEA architecture is the Zeekr 001 (unveiled on 23 September 2019 as the Lynk & Co Zero Concept) and is being launched in 2021.[8]

On 5 September 2021, Geely and Mercedes-Benz Group announced the Smart Concept #1 based on SEA, and due in 2022.[9]

Jidu Auto, a joint venture between Geely and Baidu, intends to use SEA for a full portfolio of vehicles in different segments, starting in 2022.[10]
