Inaugural Formula E champion Nelson Piquet Jr will make selected appearances in the new TitansRX rallycross series this year.
Piquet, who split with the Jaguar FE squad in March, previously competed in the now defunct American-based Global Rallycross series, winning the Washington DC round in 2015 aboard an SH Rallycross Ford Fiesta.
He will contest four rounds of the new Titans series this year, sharing one of the single-make series' Pantera RX6s with Alexander Wurz, whose participation had previously been confirmed.
"I'm very happy to be joining Titans RX, I love all forms of motorsport and I really enjoyed competing in rallycross in America a few years ago, so it will be great to get back behind the wheel of a rallycross car," said Piquet. "We're going to have a lot of fun!"
The Brazilian will race in the first two rounds of the series in France and the UK, before skipping the Portuguese weekend at Montalegre - where Wurz will drive the car.
Piquet will return for the following two events, before Wurz competes in the season-finale in Germany in October.
While Piquet's rallycross experience is largely from racing Supercar machinery in America, he has raced a single-make car in Europe before, when he competed in the British round of World Rallycross's RX Lites support category at Lydden Hill in 2014. He made the final there, but retired on the opening lap.
"It is truly a dream come true to see the starting field of Titans RX Europe 2019 go from great to fantastic," said series promoter Max Pucher.
"I am so proud to welcome Nelson Piquet Jr to the series. He has already got some Supercar rallycross experience and should be a great contender for some cool battles for a podium slot."
The opening round of the series in France, which will take place on the June 29/30 weekend, has been moved from Dreux to Essay.
