For me, the EV (Gr.X) version was really hard to adapt to, as it doesn't have gears. So I mostly ended up too fast around corners in Nurburgring and spun or off the tracks. But I really like its spontaneous acceleration, no lag at all
Haven't tried the Gr.1 version yet, still gathering up credits for Lambo Countach and LaFerrari
Haven't acquired the gr1 as of yet but its sister grx variant was easy to adapt to. Pleasant and smooth with only small adjustments for me in braking when I participated in the one make Daily Event it starred in. I surprised myself by running 2 secs off the 121 best lap qualify time.
