Dodge Omni: Which Version to Buy and Why

The Dodge Omni range in this catalogue offers two closely matched versions: 2.2 MT and 2.2 AT. Both belong to the model’s single generation, produced from 1978 to 1990 as a Hatchback 5-door. They share the same 2,212 cc Gasoline engine, 93 hp output, FWD layout, 49-litre fuel tank and 127 mm ground clearance.

The Dodge Omni range in this catalogue offers two closely matched versions: 2.2 MT and 2.2 AT. Both belong to the model’s single generation, produced from 1978 to 1990 as a Hatchback 5-door. They share the same 2,212 cc Gasoline engine, 93 hp output, FWD layout, 49-litre fuel tank and 127 mm ground clearance. The decisive difference is the transmission: the 2.2 MT has a 5-speed Manual gearbox, while the 2.2 AT uses a 3-speed Automatic. The 2.2 MT is the easier version to assess because its kerb weight and fuel-consumption figures are measured; the corresponding figures for the 2.2 AT are not measured.

Dodge Omni generations compared

There is only one Dodge Omni generation in the supplied catalogue, so there is no later generation to compare for changes in engines, body style or dimensions. The 1 generation ran from 1978 to 1990 and was offered as a Hatchback 5-door. It contains two versions, 2.2 MT and 2.2 AT. No separate restyling is listed in the data.

Because both versions cover the same production period and use the same body and engine specification, choosing between them comes down primarily to the 5-speed Manual versus 3-speed Automatic transmission. No generation-to-generation upgrade can be identified because the catalogue records one generation only.

Dodge Omni engine and specs

Both versions use a naturally aspirated 2,212 cc Gasoline engine with 4 cylinders in an Inline layout and 2 valves per cylinder. Output is 93 hp (68 kW) at 4,800 rpm. This equals approximately 42.0 hp per litre. Compression ratio is 9.5, bore and stroke are 87.4 × 91.9 mm, and the fuel system is Central injection (single-point or single- point). Both versions specify 95 fuel.

The 2.2 MT and 2.2 AT have no measured difference in engine output: each produces 93 hp and 68 kW. The Manual version provides 2 more forward gears than the Automatic. Torque is not measured for either version, so the data cannot establish which transmission provides stronger acceleration in a particular gear.

Suspension specifications are also identical. Both versions have Independent, torsion front suspension and Semi-independent, torsion rear suspension. Front brakes are Disc on both; the rear-brake specification is not measured.

Dodge Omni performance, mpg and fuel economy

Acceleration from 0–100 km/h is not measured for the 2.2 MT and not measured for the 2.2 AT. Top speed is likewise not measured for either version. Equal power alone does not prove equal performance, especially because the transmission ratios differ and the 2.2 AT kerb weight is not measured.

Fuel consumption is available only for the 2.2 MT:

For the 2.2 MT, city consumption is 2.5 L/100 km higher than highway consumption. Its combined figure of 8.2 L/100 km sits 1.2 L/100 km below the city result and 1.3 L/100 km above the highway result.

The 2.2 AT cannot be labelled more or less economical from the supplied information because all three consumption figures are not measured. Both versions have the same 49-litre tank, but driving range is not measured for either version.

Dodge Omni dimensions, weight and practicality

The supplied data identifies both versions as Hatchback 5-door models, but exterior length, width and height are not measured. Wheel sizes are also not measured for either version.

The measured 1,025 kg kerb weight of the 2.2 MT corresponds to approximately 11.0 kg per horsepower, or about 90.7 hp per tonne. The same calculations cannot be made for the 2.2 AT because its kerb weight is not measured. Gross weight is not measured for either version.

Ground clearance does not separate the choices: the 2.2 MT and 2.2 AT both provide 127 mm. Tank capacity is also equal at 49 litres.

Dodge Omni reliability and problems data

Reliability ratings, failure records and model-specific problems are not measured in the supplied data. The catalogue therefore cannot claim that either the 2.2 MT or 2.2 AT is more reliable. It also provides no maintenance-cost or repair-frequency figures with which to judge whether the Manual or Automatic transmission is the less expensive ownership choice.

The technical comparison only confirms that both versions share the same engine specification, drive type, suspension descriptions, front-brake type, ground clearance and tank capacity. Those similarities do not constitute measured reliability evidence.

Which Dodge Omni version should you buy?

Choose the 2.2 MT if you want the version supported by the more complete set of measurable data. Its 5-speed Manual gearbox has 2 more forward gears than the 2.2 AT’s 3-speed Automatic. It also has a measured 1,025 kg kerb weight, an approximately 11.0 kg-per-horsepower ratio, and recorded consumption of 9.4 L/100 km in the city, 6.9 L/100 km on the highway and 8.2 L/100 km combined.

Choose the 2.2 AT specifically if the 3-speed Automatic transmission is your preferred feature. It does not buy additional measured power: like the 2.2 MT, it produces 93 hp from 2,212 cc. It also retains FWD, a 49-litre tank and 127 mm ground clearance. However, its kerb weight, fuel consumption, acceleration and top speed are not measured, so its performance and economy cannot be compared numerically with the Manual version.

On the available evidence, the 2.2 MT is the stronger data-backed choice. The 2.2 AT remains the transmission-preference option, but the catalogue contains no prices, so it cannot determine what extra money—if any—the Automatic requires or whether that difference represents good value.
