Former European Le Mans Series LMP3 champions Mike Guasch and Christian England will return to the championship this year with United Autosports.
The pair will again contest the LMP3 category, driving a Ligier JS P3 Nissan in the six-round championship.
Guasch is back for his first full-time race campaign since winning the ELMS title with England in 2016, although he did make two LMP2 appearances in the IMSA WeatherTech SportsCar Championship last year.
The 60-year-old said he continued karting in 2018 despite not having a full-time program after plans to do more North American races failed to materialize.
“I’m very excited to come back to United Autosports,” said Guasch.
“I have wanted to come back to United for a while and the perfect deal came about and Richard and I were able to make it happen, so I’m very excited.
“I’ve stayed in contact with Christian over the last two years and we have been saying we would do something together again in the future so I was really pleased to be able to call him and tell him we were going racing again with United.”
England, meanwhile, contested the Michelin Le Mans Cup last season in a United-run Ligier-Nissan shared with Richard Meins.
“I can’t wait to get started working with Mike again,” said the 37-year-old Englishman.
“We had such a great friendship back in 2016 and of course winning the championship in our debut season was something very special.
“The competition is extremely strong in ELMS but one thing I do know is that our motivation is very high.”
United has confirmed two cars for the 2019 ELMS, with Filipe Albuquerque and Phil Hanson set to drive the team’s Ligier JS P217 Gibson in the LMP2 category.
