Starting to think this car is too quick if it’s meant to be a semi accurate representation of a car from 1984/1985. I just took the car around Suzuka in a 1:39.1 which was far from a perfect lap. I reckon the absolute best on the game would be able to get a 1:36 which would qualify them ahead of two cars in the 2014 Japanese Grand Prix!
It isn't meant to be. As mentioned in this thread and in its description in the game, it's basically just an '80s shell with modern technology underneath.
I'm not sure what segment of people that's supposed to satisfy, but I'd rather have a true 1980s F1 car. Especially on engine sound.
