2017 is history, as is the Aston Martin GT4. The car served the team extremely well, but ultimately it was too slow and heavy for where they want to be. Add into that having to spend a small fortune to fix anything on the car that breaks and its a no-brainer.
2018 is a new season, and as such is bringing in a new car. All will be revealed in a few days time at Donington circuit on the 27th March, so make sure to check back or visit the driver profiles for any announcements.
