1970 Mercury Cougar Facts and Specifications
General Year Information – 1970 Mercury Cougar Facts
For 1970, the Cougar underwent a revision to the front fascia, with the split grille with vertically slatted trim making its return. A new hood that had a pronounced body-color center section was also new. As part of the front fascia revision, a new front bumper and revised front fenders were fitted. Concave taillamp lenses remained but with revised trim bezels, as well as revised side marker lights. A change to the position of the rear axle also necessitated a new rocker panel length and rear quarter sheet metal when compared to the 1969 model. These changes not visually apparent.
Cougar also received a special option package styled by fashion designer Pauline Trigère, that included a houndstooth-patterned vinyl roof and matching upholstery; the roof and upholstery were available together or separately, in either brown-and-black houndstooth or white-and-black houndstooth check patterns. Further safety upgrades included the addition of locking steering columns and high-backed bucket seats that replaced adjustable head restraints.
The two-barrel 351 remained the base engine, with the four-barrel engine replaced by a 351 cubic-inch “Cleveland” V-8, rated at 300 hp. While unchanged in displacement, this engine was an all-new design. The 390 was dropped, with the 428 Cobra Jet remaining alongside the Boss 302 as the high-performance engine options.
Cougar Eliminator
For 1970, the standard engine for Eliminator became the 351 Cleveland 4-barrel. The Eliminator Option blacked-out exterior trim expanded from the front grille to include the hood scoop and tail light bezels. A Cougar “running cat” badge replaced the Mercury crest emblem on the fuel door, and a passenger-side racing-style mirror was added. The body side stripes, available in black only, were altered to run the length of the car along the upper belt line and now included a hood stripe, rear spoiler stripe with an “Eliminator” callout, and “Eliminator” callouts on the quarters behind the rear wheel. Exterior paint colors available for the 1970 Eliminator mimicked the “Grabber” colors in the Ford lineup and included: Competition Orange, Competition Yellow, Competition Blue, Competition Gold, Competition Green, and Pastel Blue. A Special Paint Order option was also available for Eliminators in 1970, producing single-digit examples in colors such as Black, Light Gray Metallic, White, and Red. Optional engines included: 428 Cobra Jet or Super Cobra Jet, both available with or without Ram-Air, and Boss 302 that was only available with the Eliminator Option. There were 2,268 Eliminators built for 1970
Hertz Special
The Hertz Rental Car Company purchased Cougar Eliminators as part of their “Rent-A-Racer” program. These Eliminators were ordered with the electric sunroof option, which was not available on Eliminators sold to the public. All of the Hertz Eliminators were equipped with the 351 Cleveland 4-barrel engine and FMX automatic transmission. They were also identically optioned, except for paint and interior trim colors, and the California Evaporative Emissions equipment required for the 1970 models sent to California. There were 101 Hertz Eliminators built in 1970.
