exterior styling. The only significant change was that Torino models adopted the Gran Torino grille and front fascia. Torino's weight continued to climb even though the exterior dimensions were unchanged from 1974. The Federal Clean Air Act prompted Ford to install catalytic converters for 1975 to help meet the new emission standards. Installation of the converter increased exhaust back pressure resulting in significantly reduced the power output. In response, Ford revised the base engine on all Torinos to the 351-2V engine. Along with this change, the Cruise-O-Matic transmission became standard; no manual transmissions were available. Power for all engines, except the 460, was significantly reduced compared to 1974, and along with the weight increase, fuel economy and performance continued to decrease. The 400-2V and the 460-4V were the only engine options, as the 351-4V was no longer available. The new 351M joined the line-up to replace the 351 Cleveland. Although, when a Torino was equipped with a 351-2V engine it could result in the car being delivered either the 351M or the 351W, as they were used interchangeably. The 351M and 351W had no appreciable power output difference. Due to the lack of emissions certification, the 351M was not available in California. The 351M used the 400's tall deck block and shared its connecting rods and intake manifold, resulting in more parts shared between 351M and 400 compared to the 351C and 400. This saved Ford on the engine production costs. The Gran Torino Sport remained but was virtually unchanged from the 1974 model. The Sport was almost indistinguishable from a conventional Gran Torino, and customers responded with a lack of interest. 1975 was the least popular and last year for this model; only 5,126 units were produced. Sales for the Torinos dropped off significantly from the 1974 model year. With the Elite now a separate model, Torino lost a large portion of its sales. Ford produced only 195,110 Torinos for 1975. Even with the addition of the 123,372 Elites produced for 1975, total output was 318,482 which was still significantly lower than 1974. Sales decreases were likely due to the increased demand for smaller economical cars, while Ford's more sensibly sized Granada likely also stole sales from Torino. The Ford Granada was classed as a compact by Ford, but had exterior dimensions close to that of a late 1960s Ford Torino. 1976 The 1976 model year saw no major
