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 circle 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, 2800 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
