Nissan GTR for example:


Suzuka Racing.com:


(A) 2.09 sq.m (Estimated)

(cd) 0.27

(cd x A) 0.56

at 245km/h

downforce front 24kg

downforce rear 24kg


Sportauto test:


Nissan GT-R

(A) 2,30 m²

(cd) 0,31

(cd × A) 0,71

at 200km/h

lift front 3kg

downforce rear 8kg



-Just goes to show to take information with a grain of salt.  FYI the Ferrari 360 Modena was had a MUCH greater discrepancy than the GTR.  The NSX-R remains fairly consistent.
