For 1977, Ford reduced the Thunderbird’s weight by more than 900 lbs, slashed the price by thousands, and created the best selling T-Bird in history.

The sixth-generation Ford Thunderbirds of 1972-76 were the largest and most luxurious T-Birds in history. In fact, the Big ‘Bird, as it was known, was nearly a clone of the Lincoln Continental Mark IV, the preeminent luxury cruiser of the 1970s. But with the introduction of the federal government’s Corporate Average Fuel Economy (CAFE) standards, which required the Ford Motor Company’s passenger car fleet to average 18.0 mpg by 1978, the thirsty Big ‘Bird would have to be retired. So for 1977, the Thunderbird was moved from the Continental to the Torino/LTD II platform, chopping off nearly 10 inches in length and 900 to 1,100 lbs to create a more fuel-efficient package.

Actually, the new T-Bird shared more than a little with the ’72-’76 Torino and ’77-on LTD II package, including the 114-in wheelbase body-on-frame chassis, suspension, and running gear. Many sheet metal components, interior pieces, and trim were borrowed from the Ford Elite, Torino, and Mercury Cougar. And as often noted, the Thunderbird bore more than a passing resemblance to the LTD II Coupe due to their common silhouette. Where the T-Bird differed was in its hidden headlamps, full-width tail lamp, and B-pillar and quarter window treatment. Design manager Dave Royer is credited with the look, working under studio director Gene Haldeman. assistant design VP Jack Telnack, and VP Gene Bordinat.

With the 460 cubic-inch 385-series V8 banished from the lineup, the base engine was now a 302 cubic-inch Windsor V8 with just 130 SAE net horsepower. (California ‘Birds got a 351M V8 to meet the state’s stricter emissions rules.) Optional upgrades included two 351 CID V8s with 135 or 149 hp and a 400M V8 with 173 hp, while the only available transmission was a three-speed Cruise-O-Matic. The base V8 was EPA rated at 15 mpg city, 19 highway, and 17 combined—almost in line with the new government-mandated corporate average. (See Ford’s 60-second sales pitch here.)

Thunderbird Town Landau 

Along with the improved fuel economy, there was one more important development with the move to the mid-sized platform. Ford slashed the list price from $7,790 to $5,063, moving the Thunderbird from its founder’s slot at the premium end of the personal luxury coupe category to the mass market, alongside the Chevrolet Monte Carlo and the rest. Now open to a much wider audience with the $2,700 price cut, T-Bird sales exploded to more than 318,000 cars in 1977, six times the 1976 volume. And with its distinctive styling and the prestige of the name, the mid-size Thunderbird outsold the similar LTD II Coupe by nearly four to one.

In mid-season ’77, Ford rolled out the Town Landau, a Thunderbird  loaded up with fancier trim, a brushed aluminum roof tiara, more standard equipment, and a base price of $7,990, back in Big ‘Bird territory. However, since the Town Landau was an option package rather than a standalone model, the production numbers were never broken out and its impact is difficult to gauge. But the Torino ‘Bird (as it was later nicknamed by T-Bird enthusiasts) sold in even greater numbers in ’78: almost 353,000 cars, the biggest year in Thunderbird history. By the end of ’79, the final year for the Torino ‘Bird, more than 955,000 cars were sold. There would be four more generations of Ford Thunderbirds, but that record was never equaled.
