The M-Sport driver suffered a power loss in during his pass through stage three (Lankamaa, 14.21km) on Friday morning which was caused by an impact to the bottom of his Ford Puma.
Tanak, who started the day leading the rally after winning Thursday night’s Super Special, believes his car struck a bedrock during the stage which went through the car’s sump guard.
The impact caused terminal damage to the engine which will likely force Tanak out of the rally completely. It is the second rally in succession that the 2019 world champion has suffered an engine issue after M-Sport were forced to change a power unit prior to the start of Rally Estonia.
Tanak was able to run on EV mode briefly after losing power, although part of the reason to engage that power mode was to help cool the car after a fire ignited.
“In a very fast place it seems we touched a bedrock or something on the road in a compression and obviously it has broken the sump guard and gone through the sump guard,” said Tanak.
“I can see underneath that the starter motor is cracked and is broken and other than that I cannot find anything else but the oil from the engine has gone out and the engine is clearly broken.
