The Mustang Grande was back for 1970 model year after its decent debut in 1969. It was still considered the “fancy hardtop” Mustang and was not really changed for 1970. The Grande, was a hardtop with special trim and a deluxe interior similar to the Mach 1’s interior. It also got a vinyl roof and a more luxurious interior, upgraded two-spoke steering wheel, new wheel covers, color keyed racing mirrors, an electric clock, bright exterior moldings, dual outside paint stripes and luxury foam bucket seats.
The Mustang Grande models offered five sporty houndstooth design patterns that were popular in 1970. Another new option package featured automatic seat-back release, parking brake warning lights, remote-controlled outside mirror and lights for the trunk, glove box and instrument panel.
It still had its luxurious Comfortweave interior to set it apart from other cars on the market. It was available in only the hardtop body style. The Mustang Grande featured an upgraded interior with imitation wood trim, a smoother, more refined ride and additional sound-deadening materials. More than twice the usual amount of insulation (55 pounds) helped soak up noise and vibrations.
The Grande could have any Mustang engine, starting with the 200- or 250-cid six, on up through any of half a dozen V-8s (all the way to the Cobra Jet). Decorated by narrow two-tone stripes, racing mirrors, and wire-style wheel covers, Grandes had a manual three-speed or optional SelectShift, with T-bar gearshift lever. Black and white vinyl roofs were available.
