Thierry Neuville suffered a nasty crash in a private test, his first since the season was suspended in March.
Earlier in April, manufacturers were forbidden from conducting any testing until May 30 to prevent anyone from gaining an unfair advantage during the suspension imposed due to pandemic.
The deadline having expired, Hyundai arranged a multi-day test for Neuville in Finland to get the crew up to speed ahead of the season resumption.
However, the test was short-lived as the Belgian driver careened off the road at a high rate of speed, with his Hyundai i20 suffering a roll before landing on its left side.
Both Neuville and co-driver Nicolas Gilsoul were unhurt in the accident, but the damage inflicted on the car was such that Hyundai were forced to abandon the test after a single day.
The team is now returning to its base in Alzenau, with a second test yet to be arranged.
