It's really quite simple.
It has begun. According to a new report coming from Motorsport, Ford has officially begun track testing of the race-spec GT that'll participate in Le Mans. In fact, this source is also claiming that Ford might reveal this track-only GT next months at this year's Le Mans 24 Hours. More than likely, the GT will race in next year's event. So how much will the race-spec GT differ from the also upcoming road-going version? Apparently not dramatically.
The racing GT will be powered by a Roush Yates EcoBoost 3.5-liter turbo V6 and mated to a Ricardo-designed and built gearbox. Its final design was done in England by a team led by former Lola LMP designer Julian Sole. Testing itself has just taken place at the Calabogie Motorsports Park in Ontario, Canada. More extensive shakedowns are planned. If the car isn't ready for a public debut next month, then expect to see it premiere instead at the Daytona 24 Hours next January.
