Mercedes unofficially entered Formula E a season ahead of their debut through their affiliation with HWA. On 9 May 2018, HWA confirmed that it will enter the 2018–19 season as a customer team, using powertrains from Venturi, who HWA had already been in partnership with regarding technical support. On 8 October 2018, the HWA Racelab team has been officially launched, revealing the car along with Gary Paffett as its first driver. Stoffel Vandoorne was later confirmed as Paffett's teammate, moving straight to Formula E from his McLaren F1 drive that was coming to a close. HWA had a very complicated start to the season, not scoring any points in its first four races. In the season's fifth race in Hong Kong, HWA surprised with their pace in wet conditions during the weekend, with Vandoorne even qualifying on pole, giving HWA its first three points in the championship. Paffett qualified fourth. Vandoorne then retired from the race after a driveshaft failure, while Paffett finished eighth, which was HWA's first points finish. HWA then scored another points and first podium in Rome, where Vandoorne finished third. The car broke down immediately after the race due to another driveshaft failure. Venturi's reliability improved in the second half of the season, giving HWA a better chance at good results. Vandoorne was a regular points scorer, but the car wasn't quick enough in races to compete for podiums. HWA finished ninth in the Teams' Championship and scored 44 points in their one-off season.
2019–20 season
Mercedes' official debut, under the name of Mercedes-Benz EQ Formula E Team, took place in November 2019 at the Diriyah ePrix, which is a double-header event. In a form of continuity, the team will utilize the groundwork laid by HWA, rather than completely reworking the team structure. In addition to the established pairing of Paffett and Vandoorne, the team has also used Edoardo Mortara, Esteban Gutiérrez and Nyck de Vries in pre-season testing. Mercedes' first contender, dubbed the Mercedes-Benz EQ Silver Arrow 01, was unveiled in March 2019. It featured a 'teaser' black livery, resembling the HWA car already in competition. The car went on to appear at various events, in promotion of Mercedes' Formula E entry, including the 89th Geneva International Motor Show. In September 2019, the team announced it had signed Danish wind power company Vestas as a principal partner. On 11 September, Mercedes revealed the definitive look of their car, along with their new team principal and drivers. Stoffel Vandoorne will continue with team, becoming their 1st driver, but he will be partnering with the 2019 FIA Formula 2 Champion Nyck de Vries. The team will be managed by Ian James. In October, it was announced that the team will supply its new powertrain to Venturi Racing, reversing the manufacturer-customer relationship in the favor of Mercedes. In pre-season testing, which was held at Circuit Ricardo Tormo, Mercedes were the second slowest team in overall classification, only outpacing NIO 333. Vandoorne, however, won one of the two simulation races that were held during the week. Felipe Massa from Venturi was the fastest Mercedes-powered driver of the week, finishing twelfth in the overall classification. On 15 November, the team confirmed Gutiérrez to join Paffett as a second reserve and development driver. Mercedes-Benz got the podium in the first and second race, and able to lead the Team's Championship in the two opening races. But, Mercedes can't get its momentum going in the next races. Mercedes' first retirement is in Mexico E-Prix when Nyck de Vries got mistake in Turn 1 defending from Antonio Felix da Costa. Nowaday Mercedes' got 5th in Team's Championship outscored by DS TeCheetah, BMW, Panasonic Jaguar, and Nissan.
