At the end of the year he took part in the 1996 EFDA Nations Cup for Formula Opel cars, representing Brazil alongside compatriot Wagner Ebrahim and taking third place.

He remained in the championship for 1998, driving an ADR-run Dallara chassis, and improved to seventh place overall, with two podium finishes, well ahead of teammates Yudai Igarashi and Miku Santavirta.

However, his performance was overshadowed by his compatriots Mario Haberfeld, Enrique Bernoldi and Luciano Burti, who dominated the championship between them, taking the top three positions in the drivers' standings.

Maurício moved up to International Formula 3000 for the 1999 season, driving for Super Nova alongside Jason Watt, but after a difficult start he was dropped after three races in favour of David Saelens.

He stayed with the team alongside Bernoldi for 2000, making up for a seven-race run of retirements at the start of the season by securing his first podium finish in the category at the Hungaroring, improving his final championship position to 17th.

[2] Maurício began the 2001 season without a drive, despite initially being reconfirmed at the Red Bull Junior Team alongside Patrick Friesacher, who replaced the Formula One-bound Bernoldi.

For 2004, Maurício returned to Brazil to take part in the Stock Car Brasil championship, a common location for Brazilian ex-single seater drivers.

For 2008, WA Mattheis switched cars to the Peugeot 307, which Maurício took to championship victory with five wins from the twelve races, narrowly beating the Astras of Marcos Gomes and Thiago Camilo in the process.
