Geo Metro: Which Version to Buy and Why

The Geo Metro Cabrio was produced from 1989 through 1997 in a single generation. The catalogue lists eight entries, but they represent four recurring version names: 1.0 MT, 1.0 AT, 1.3 MT, and 1.3 AT.

The Geo Metro Cabrio was produced from 1989 through 1997 in a single generation. The catalogue lists eight entries, but they represent four recurring version names: 1.0 MT, 1.0 AT, 1.3 MT, and 1.3 AT. The main buying choice is therefore between a 993 cc three-cylinder engine with 56 hp and a 1298 cc four-cylinder engine with 70 hp, followed by a choice between a 5-speed Manual and a 3-speed Automatic. The 1.3 engine adds 14 hp and 21 Nm over the 1.0, while the Manual versions are the only ones with a measured kerb weight.

Geo Metro generations and versions

The Geo Metro has 1 generation in the supplied catalogue. This generation ran from 1989 to 1997, used the Cabrio body, and contains 8 listed modifications. The version names repeat within the generation: there are two entries each for 1.0 MT, 1.0 AT, 1.3 MT, and 1.3 AT. Their engine, transmission, drive, clearance, tank, and suspension specifications are identical within each matching pair. The recorded difference is in the front-brake description: one set has Ventilated disc front brakes, while the other is recorded as Disc front brakes. Every listed version has Drum rear brakes.

There is no second generation to compare with the first, and the data does not identify a separate restyling. A buyer is choosing among powertrains and gearbox types within the same 1989–1997 generation rather than between different generations.

Engine and specs comparison

The 1.0 MT and 1.0 AT use the same front, transverse 993 cc Gasoline engine. It has 3 Inline cylinders, 2 valves per cylinder, No boost, a 9.5 compression ratio, and a 74 × 77 bore-and-stroke figure. Output is 56 hp at 5700 rpm and 79 Nm at 3300 rpm.

The 1.3 MT and 1.3 AT share a front, transverse 1298 cc Gasoline engine. It has 4 Inline cylinders, 2 valves per cylinder, No boost, a 9.5 compression ratio, and a 74 × 75.5 bore-and-stroke figure. It develops 70 hp at 5500 rpm and 100 Nm at 3000 rpm.

Both engines are recorded with Direct injection (direct). All versions are FWD. The Manual has 5 gears, whereas the Automatic has 3.

Power per litre and weight per horsepower

Calculated from the supplied displacement and output figures, the 1.0 produces about 56.4 hp per litre. The 1.3 produces about 53.9 hp per litre. The smaller engine therefore has roughly 2.5 more hp per litre, but this does not make it the more powerful choice: the 1.3 still provides 14 hp more overall.

The torque comparison also favours the 1.3. Its 100 Nm output is 21 Nm above the 1.0 engine’s 79 Nm. Maximum torque is listed at 3000 rpm in the 1.3, which is 300 rpm lower than the 1.0 engine’s 3300 rpm figure. Maximum power is recorded at 5500 rpm for the 1.3 and 5700 rpm for the 1.0, a difference of 200 rpm.

Measured kerb weight is available only for the Manual versions. The 1.0 MT weighs 750 kg, giving approximately 13.4 kg per hp. The 1.3 MT weighs 826 kg, or approximately 11.8 kg per hp. Although the 1.3 MT is 76 kg heavier, its additional output improves the calculated weight-to-power burden by approximately 1.6 kg per hp. On the available figures, the 1.3 MT offers the stronger power-to-weight proposition.

Kerb weight for the 1.0 AT and 1.3 AT is not measured, so a valid weight-per-horsepower comparison cannot be calculated for either Automatic.

Performance, mpg, and fuel economy

For 1.0 MT, acceleration from 0–100 km/h is not measured, top speed is not measured, city fuel consumption is not measured, highway fuel consumption is not measured, and combined fuel consumption is not measured.

For 1.0 AT, acceleration from 0–100 km/h is not measured, top speed is not measured, city fuel consumption is not measured, highway fuel consumption is not measured, and combined fuel consumption is not measured.

For 1.3 MT, acceleration from 0–100 km/h is not measured, top speed is not measured, city fuel consumption is not measured, highway fuel consumption is not measured, and combined fuel consumption is not measured.

For 1.3 AT, acceleration from 0–100 km/h is not measured, top speed is not measured, city fuel consumption is not measured, and highway and combined fuel consumption are not measured.

Because no consumption figures are measured, the data cannot support an mpg ranking between the 1.0 and 1.3 engines or between the Manual and Automatic gearboxes. CO₂ output and environmental class are also not measured for every version.

Dimensions, weight, clearance, tank, and wheels

Every 1.0 MT entry has a measured kerb weight of 750 kg. Every 1.3 MT entry has a measured kerb weight of 826 kg. Kerb weight is not measured for 1.0 AT or 1.3 AT, and gross weight is not measured for any version.

All four version names have 160 mm of ground clearance and a 40-litre fuel tank. Wheel sizes are not measured for 1.0 MT, 1.0 AT, 1.3 MT, or 1.3 AT.

The chassis specification is otherwise consistent across the range. Every version has Independent, spring front suspension and Independent, spring rear suspension. Rear brakes are Drum throughout. Depending on the duplicate catalogue entry, front brakes are recorded as either Ventilated disc or Disc, so this item should be checked against the exact car represented by the listing.

Reliability and problems

Reliability ratings, fault records, service intervals, and model-specific problems are not measured in the supplied data. The specifications therefore cannot establish whether 1.0 MT, 1.0 AT, 1.3 MT, or 1.3 AT is the most reliable version. Likewise, the data does not support claims about repair costs, parts durability, or recurring mechanical issues.

What can be compared is mechanical configuration: the 1.0 versions have 3 Inline cylinders and the 1.3 versions have 4 Inline cylinders; the Manual versions have 5 gears and the Automatic versions have 3. These differences describe the cars but do not, by themselves, prove a reliability advantage.

Which Geo Metro version should you buy?

The 1.3 MT is the strongest specification-led choice. It combines the range’s highest output—70 hp and 100 Nm—with the 5-speed Manual gearbox. Against the 1.0 MT, it adds 14 hp and 21 Nm while adding 76 kg. Its calculated 11.8 kg per hp is better than the 1.0 MT’s approximately 13.4 kg per hp. It also reaches its listed torque peak 300 rpm earlier.

Choose the 1.0 MT if lower measured kerb weight matters more than maximum output. At 750 kg it is the lightest version with a recorded weight, 76 kg below the 1.3 MT. It retains the 5-speed Manual gearbox, but its output falls to 56 hp and 79 Nm.

Choose the 1.3 AT when an Automatic gearbox is the priority but you still want the higher-output engine. It has the same 70 hp and 100 Nm as the 1.3 MT, paired with a 3-speed Automatic. Its acceleration, top speed, consumption, and kerb weight are not measured, so those factors cannot be compared responsibly with the Manual.

The 1.0 AT combines the 56 hp, 79 Nm engine with the 3-speed Automatic. It is the least compelling selection if the decision is based solely on measured output and gearbox ratio count: it has 14 hp and 21 Nm less than the 1.3 AT while sharing the same number of gears. However, performance, economy, and weight data are not measured, so the available figures cannot show how large the real-world difference is.

Overall, buy the 1.3 MT for the best measured power-to-weight result and the highest torque, the 1.0 MT for the lowest recorded kerb weight, or the 1.3 AT if Automatic transmission is essential. With two catalogue entries under each exact version name, confirm whether the individual car has Ventilated disc or Disc front brakes before choosing between otherwise matching examples.
