OH yes, the Aerodynamics from the AA4 is much better.
At the aerodymanic for the AA 2, 3, 3.5 is like a british truck height 4,30 meter
And the aerodynamic for the AA 4 is like a european truck with a height of 2,70 meter O0 >:D

Very interesting stuff. The fact that my 3.5 sc with 315 hp had a 235kmh top speed compared to the 220hp civic with a higher topspeed while it ways 2 times as much kind of gave it away allready😁

Digging through my inbox trying to clear some space and I found this from my colleague Wouter over at Airshaper (they do virtual wind tunnel work for various folk, including race teams).

His model (using public domain info only) suggests that there was a LOT of drag to be found on an Atom 2! https://ariel.club/wp-content/uploads/2 ... l-Atom.pdf

Seems an Atom 2 is about as slippery as a truck, so am guessing the 4 is much improved!
