The drag coefficient published for a particular vehicle will reflect any induced drag associated with the design.Like a Bugatti Veyron,with I think,three different Cds as a function of its rear wing orientation.
In a perfect world,we'd get front and rear lift coefficients,along with the Cd of a specific vehicle.Manufacturers may not want the average guy (and competitors) to have access to lift data.
When Darko measured my truck they provided me with front and rear lift forces at 130-mph.Based upon the 29-sq-ft frontal area and 130-mph velocity,it will be an easy matter to deduce the front/rear lift coefficients.
An LT1 Corvette at Bonneville,that was measured at Darko few days before me indicated front lift and at 220-mph got sideways,went vertical,did a reverse endo,then crashed onto its nose before getting its parachute out.The driver walked away but was visibly shaken.The SCTA and USFRA may want to discuss air fences further forward of the cowl.
If you want lift data on some cars you may have to pay for them.
