I have compared turning circles from two RWD makes (BMW and Holden) and two FWD makes (Buick and Citroen). I did a linear regression of turning circl e versus wheelbase using at least 5 medium to large size cars of each make. Then computed turning circles for each at reference wheelbases of 2700, 2
800 and 2900 mm. These are kerb to kerb in metres.
2700 2800 2900
10.8 11.1 11.4 Holden
11.1 11.4 11.7 BMW
11.4 12.0 12.6 Citroen
11.4 11.9 12.3 Buick
