The most obvious change for the 1973 model saw was a new front fascia, required to meet new federal regulations.
The new regulation mandated that all cars manufactured after September 1, 1972 must be able to take a 5 mph (8.0 km/h) strike to the front without damaging safety related components such as headlamps and the fuel system.
For 1973 only, rear bumpers had a 2.5 mph (4.0 km/h) requirement.
The Torino's front end featured totally new sheetmetal from the firewall forward, with a blunt, more squared-off fascia replacing the previous year's pointed prow.
The new large square 5 mph (8.0 km/h) energy absorbing bumper replaced the almost body-fitting chrome bumper used on the front of the 1972 Torino.
The new larger bumpers caused all Torino models to increase in length by at least 1 in (25 mm), and weight also increased by at least 100 lb (45 kg) for all models.
Rear bumpers and taillights were unchanged from 1972.

Separate grille designs were still maintained for Torino and Gran Torino models; they mimicked the 1972s in design.
The Gran Torino now had a more rectangular grill with the parking lamps horizontally placed in the grille, but the quad headlights were still surrounded with a chrome bezel.
Base Torino models had a wider full width grill that surrounded the headlamps; however, the parking lamps were located on the outer edge of the fascia.
The leading edge of the hood was squared off to follow the fascia's lines, and all models shared the same hood.
The 1973 Torino used the same rear bumper as the 1972 Torino, and incorporated minor changes to meet the 2.5 mph (4.0 km/h) mandate.
Rear bumpers now had new brackets that increased the space between the bumper and the sheetmetal, an impact strip and bumper guards.

The model line-up for 1973 increased to 11 from the 9 models in 1972.
The model line-up consisted of "Torino", "Gran Torino", "Gran Torino Sport", and "Gran Torino Brougham."
The "Gran Torino Brougham" was available as a 2-door hardtop and a 4-door sedan.
Other models were offered in the same body styles as 1972.
Bench seats for 1973 reverted to low backs with separate head rests to increase rear visibility.
The high back bucket seats were still available on the two-door models.
The hood release was moved to inside for increased security.
All models used larger 11-inch (279 mm) rear drum brakes for 1973 to help cope with the extra weight; 1972 models used 10 in (254 mm) drums.
Radial tires were added to the option list which offered longer tread life and better road manners.


The standard engine remained the 250 CID inline-six for all models except the station wagons and Sport, which used the 302-2V. Engine options also remained the same, but all engines now had their compression ratio dropped to 8.0:1.
Power for all engines was slightly lower than in 1972.
The 351 CJ continued to be the only high-performance engine and only saw a 2 hp (1.5 kW) drop from 1972.
Police package Torinos had the same engine options as the civilian models but with the addition of a high-performance 460-4V exclusive to the "Interceptor" package.
 
For 1973, Gran Torino Sport had its own unique emblem, which it displayed in the grille and on the trunk lock cover.
The laser stripe was revised to a slightly different shape, and ran higher along on the body side.
The Sport no longer had a hood scoop, and the Ram Air induction option was gone.
The Sport was available as a 2-door SportsRoof or a 2-door hardtop but was otherwise unchanged from the 1972 model year.
In the Car and Driver magazine road test of a 1973 Gran Torino Sport, the suspension was noted to be a good balance of comfort and handling.
Car and Driver wrote that the Torino was as "..quiet as a Jaguar, smooth as a Continental, the Torino's ride is exceptional...even with the competition suspension."
Their test of a SportsRoof equipped with the 351 CJ, C-6 automatic, and 3.25:1 gears, resulted in a 0 - 60 mph (97 km/h) time of 7.7 seconds while the quarter mile went by in 16.0 seconds at 88.1 mph (141.8 km/h).
The 0 - 60 mph time was 0.9 seconds slower than the 1972 model
