Reliability in the engine is the reported cause for the departure.
Telmex Ganassi Racing has packed up early and left the track following two days of testing at Daytona International Speedway, and the fastest time so far with Jamie McMurray's time of 1:38.980 (129.481 mph) in the No. 01 Telcel/Target Ford EcoBoost/Riley.
Reasons for the five-time Daytona 24 winning team's premature departure were not immediately given but regular driver Memo Rojas released a statement in Spanish on social media.
According to Rojas, the team "have decided to focus on doing more working in the workshop to develop the new engine and turbo mounted on the two team cars. Before this decision, the #01 had set the fastest time of the day."
This means Telmex Ganassi Racing will miss the third and final day of the roar before the Rolex 24, losing valuable track time ahead of the inaugural TUDOR United SportsCar Championship opening round at Daytona at the end of the month.
The No. 60 Michael Shank Racing Riley-Ford have also elected to sit out the final day of testing on Sunday. Both teams are running Ford EcoBoost powerplants.
“We have a couple of problems,” team owner Mike Shank told Sportscar365. “We want to make sure we maximize all the reliability things we can. It’s not the motor itself. It’s the things that hang on it.
“We’ve opted to get my trucks home early to beat the snow storm and be able to hit the ground running Monday morning to get after some of these ancillary things that we need to have.”
