Alfa Romeo GTA Coupe: Which Version to Buy and Why

The Alfa Romeo GTA Coupe catalogue contains two versions, both named 1.3 MT, within a single generation produced from 1965 to 1975. Their core specifications are identical: each has a 1,297 cc Gasoline engine with 4 Inline cylinders, Turbo boost, a 5-speed Manual gearbox, and RWD. The decisive difference is output. One 1.3 MT develops 110 hp (81 kW), while the other develops 160 hp (118 kW).

The Alfa Romeo GTA Coupe catalogue contains two versions, both named 1.3 MT, within a single generation produced from 1965 to 1975. Their core specifications are identical: each has a 1,297 cc Gasoline engine with 4 Inline cylinders, Turbo boost, a 5-speed Manual gearbox, and RWD. The decisive difference is output. One 1.3 MT develops 110 hp (81 kW), while the other develops 160 hp (118 kW). Therefore, the choice is straightforward: select the 110 hp 1.3 MT when lower output is preferable, or the 160 hp 1.3 MT when maximum power from the listed engine is the priority.

Alfa Romeo GTA Coupe generations compared

There is only 1 generation of the Alfa Romeo GTA Coupe in the supplied catalogue, so there is no later generation to compare for changes in engines, body style, transmission, or drive. The 1 generation ran from 1965 to 1975, used a Coupe body, and included 2 versions. Both versions cover the same production period, and no separate restyling is identified in the data.

Because the catalogue lists a single generation, the buying decision is entirely a comparison between its two power outputs. Neither version gains a different gearbox, drive system, engine displacement, cylinder arrangement, boost type, suspension layout, brake type, or ground clearance.

Alfa Romeo GTA Coupe engine and specs

Both catalogue entries must be distinguished by power because they share the exact version name 1.3 MT.

The 160 hp 1.3 MT produces 50 hp and 37 kW more than the 110 hp 1.3 MT. That is approximately 45.5% more horsepower from the same listed 1,297 cc displacement.

Calculated specific output makes the distinction clearer. The 110 hp 1.3 MT delivers approximately 84.8 hp per litre, while the 160 hp 1.3 MT delivers approximately 123.4 hp per litre. The stronger version consequently provides about 38.6 hp per litre more.

Apart from power, the recorded engine and drivetrain specifications do not separate the versions. Both are Gasoline, 4-cylinder Inline, Turbo, 5-speed Manual, and RWD models.

Performance and economy

The supplied data does not include acceleration or maximum-speed measurements for either 1.3 MT.

Although the 160 hp 1.3 MT has more power, the absence of measured acceleration and top-speed figures means the size of any real performance advantage cannot be quantified from this catalogue. Fuel-consumption figures are also not measured, so there is no numerical basis for claiming that either version uses less Gasoline.

Alfa Romeo GTA Coupe dimensions and weight

The available dimensional data records 120 mm of ground clearance for both versions. Kerb weight, gross weight, tank capacity, and wheel sizes are not measured.

Because kerb weight is not measured, weight per horsepower cannot be calculated for either 1.3 MT. It is also impossible to determine whether the versions differ in mass or whether the stronger model has a better power-to-weight ratio. The identical 120 mm ground-clearance figure gives neither version an advantage in that specification.

Both versions use Independent, spring front suspension and Dependent, spring rear suspension. Each also has Disc front brakes and Disc rear brakes. On the supplied chassis specifications, the versions are equal.

Which Alfa Romeo GTA Coupe version should you buy?

Choose the 1.3 MT (160 hp) if power is the main criterion. It retains the same 1,297 cc Gasoline, 4 Inline cylinder, Turbo, 5-speed Manual, and RWD specification as the weaker version while adding 50 hp and 37 kW. Its calculated output is approximately 123.4 hp per litre, compared with approximately 84.8 hp per litre for the 110 hp 1.3 MT.

Choose the 1.3 MT (110 hp) if the lower-output configuration is specifically what you want. It has the same production years, body type, displacement, fuel label, cylinder count and layout, boost, gearbox, drive, suspension, brakes, and 120 mm ground clearance as the 160 hp 1.3 MT. However, no economy, weight, acceleration, or top-speed measurements are available to establish an additional numerical advantage for the lower-output version.

There is no price data, so the extra money required for the 160 hp 1.3 MT is not measured and value for money cannot be calculated. Based strictly on the supplied specifications, the stronger 1.3 MT is the more compelling choice because it provides 45.5% more horsepower without a recorded change in displacement or the other listed mechanical specifications. The 110 hp 1.3 MT remains the alternative for buyers deliberately seeking the less powerful version rather than a measured advantage in economy, weight, or dimensions.
