What is a "touring car?"

[Ron Earp]

Some data I had handy in a spreadsheet:

Car	Cd	Area (sq ft)	CdA
RX7	0.31	19.19	5.95
Integra	0.33	19.50	6.44
Camaro	0.34	22.00	7.44
Mustang	0.36	22.50	8.10
280zx	0.39	21.00	8.09
TR8	0.42	20.70	8.69
240Z	0.44	21.00	9.24

That's nifty info. Do you have the years those numbers apply as well? i.e. RX7 had 3 body styles and various bumpers and whatnot across its life. Same with Integra, Camaro, Mustang...
