The 1970 Dodge Challenger R/T and 1967 Mercury Cougar GT 390 stand as two of the most notable Pony Car cars from Muscle era. Both emerged during a period of intense competition, and choosing between them remains a passionate debate among collectors. The 1970 Dodge Challenger R/T holds a clear advantage in raw power with 375 hp compared to 320 hp, a 55-horsepower difference that shapes the driving experience. Under the hood, the contrast is notable: the Dodge Challenger uses a V8 OHV (RB big-block) displacing 7,210 cc, while the Mercury Cougar relies on a V8 OHV with 6,391 cc. In the sprint to 60 mph, the 1970 Dodge Challenger R/T edges ahead at 5.8 seconds versus 6.5 seconds.

Both trade at comparable values on the collector market, making the choice between them largely one of personal preference.
