That sameness is the point of a version choice: the chassis numbers do not split the range; the engines and gearboxes do.

Engines and specs

All listed engines are Gasoline, 4 or 6 cylinders, boost No except 2.5 MT (210 hp) (Turbo). Use the exact names; duplicate names are split by horsepower.

Power per litre (hp per 1000 cm³, from the table): 2.5 MT (210 hp) 85.4; 2.0 MT (140 hp) 70.2; 2.0 MT (136 hp) 68.2; 2.0 MT (120 hp) 60.2; 2.2 MT (124 hp) 56.9; 2.7 MT (144 hp) 53.3; 2.2 MT (116 hp) 53.2; 2.0 MT (103 hp) 51.6; 2.2 MT (110 hp) and 2.2 AT (110 hp) 50.8; 2.9 MT (136 hp) and 2.9 AT (136 hp) 47.7. The smallest 2.0 injection fours beat the 2.9 V-shaped sixes on specific output. Compression where measured: 2.5 MT 8.1; 2.0 MT (103 hp) and 2.2 2165 cm³ lines 9.2; 2.0 MT (136/140 hp) 9.3; 2.9 9.5; 2.0 MT (120 hp) 10. Bore × stroke: 2.0 lines 88 × 82; 2165 cm³ 88 × 89; 2.5 MT 91 × 63; 2.9 91 × 73; 2180 cm³ and 2.7 MT not measured.

Performance and economy (mpg-style litres, 0-100, top speed)

Measured 0–100 km/h, fastest to slowest: 2.5 MT (210 hp) 7.4 s; 2.0 MT (136 hp) and 2.0 MT (140 hp) 9.9 s; 2.7 MT (144 hp) and 2.9 MT (136 hp) 10.0 s; 2.0 MT (120 hp) and 2.2 MT (124 hp) 10.3 s; 2.0 MT (103 hp) and 2.2 MT (110 hp) 11.6 s; 2.2 AT (110 hp) 12.4 s. Not measured: 2.2 MT (116 hp), 2.9 AT (136 hp).

Top speed, where measured: 2.5 MT 233 km/h; both 136/140 hp 2.0 MT 203; 2.0 MT (120 hp) 195; 2.0 MT (103 hp) and 2.2 MT (110 hp) 187; 2.2 AT (110 hp) 183. Not measured: 2.2 MT (116 hp), 2.2 MT (124 hp), 2.7 MT (144 hp), 2.9 MT (136 hp), 2.9 AT (136 hp).

Mixed consumption, where measured: 2.0 MT (120 hp) 7.4; 2.0 MT (103 hp) and 2.2 MT (110 hp) 8.1; 2.2 AT (110 hp) 8.3; 2.0 MT (136 hp) and 2.0 MT (140 hp) 8.5; 2.5 MT (210 hp) 9.6. City / highway on those same lines: 10.9 / 6.0 (120 hp 2.0); 12.1 / 6.5 (103 hp 2.0 and 110 hp 2.2 MT); 12.6 / 6.8 (110 hp 2.2 AT and both 136/140 hp 2.0); 14.7 / 7.6 (2.5 MT). Not measured for 2.2 MT (116 hp), 2.2 MT (124 hp), 2.7 MT, 2.9 MT, 2.9 AT.

Arithmetic that matters at the pump: 2.0 MT (120 hp) uses 2.2 l/100 km less mixed than 2.5 MT (210 hp) (9.6 − 7.4). On the 72 l tank that is about 9.7 l saved per fill if both ran at mixed figures, and the 120 hp 2.0 still reaches 195 km/h. 2.2 AT (110 hp) costs 0.8 s and 4 km/h versus 2.2 MT (110 hp) (12.4 vs 11.6 s, 183 vs 187 km/h) and 0.2 l/100 km mixed (8.3 vs 8.1). 2.0 MT (103 hp) and 2.2 MT (110 hp) share 11.6 s and 187 km/h and 8.1 mixed; the extra 170 cm³ and 7 hp of the 2.2 do not show up in those three figures.

Dimensions and weight

Ground clearance 120 mm and tank 72 l do not change with version. Wheel size not measured on any line.

Kerb / gross, where measured:

• 2.0 MT (103 hp): 1180 / 1605 kg
• 2.0 MT (120 hp): 1180 / 1690 kg
• 2.2 MT (110 hp): 1220 / 1705 kg
• 2.0 MT (136 hp) and 2.0 MT (140 hp): 1270 / 1710 kg
• 2.5 MT (210 hp): 1410 / 1870 kg
• 2.2 AT (110 hp): kerb not measured / gross 1705 kg
• 2.2 MT (116 hp), 2.2 MT (124 hp), 2.7 MT (144 hp), 2.9 MT (136 hp), 2.9 AT (136 hp): kerb not measured, gross not measured

Payload from measured pairs: 2.0 MT (103 hp) 425 kg (1605 − 1180); 2.0 MT (120 hp) 510 kg (1690 − 1180); 2.2 MT (110 hp) 485 kg (1705 − 1220); both 136/140 hp 2.0 440 kg (1710 − 1270); 2.5 MT 460 kg (1870 − 1410). The 120 hp 2.0 is the lightest car with the largest measured payload.

kg per hp (kerb / hp): 2.5 MT (210 hp) 6.71; 2.0 MT (140 hp) 9.07; 2.0 MT (136 hp) 9.34; 2.0 MT (120 hp) 9.83; 2.2 MT (110 hp) 11.09; 2.0 MT (103 hp) 11.46. The turbo four is in a different weight-to-power band from every naturally aspirated line with a kerb figure.

Which version to choose

If you want the lowest measured fuel use: 2.0 MT (120 hp). It is the only line with mixed 7.4, city 10.9, highway 6.0. Versus 2.0 MT (103 hp) it adds 17 hp and 6 Nm, cuts 0–100 by 1.3 s (11.6 → 10.3), raises top speed by 8 km/h (187 → 195), and still sits on 1180 kg kerb. The mechanical swap in the data is Carburetor and Front, longitudinal versus Distributed injection (multi-point) and Front, transverse, plus compression 9.2 versus 10. Gross weight is 85 kg higher (1690 vs 1605), so the 120 hp car carries more, not less.

If you want the strongest 2.0 without turbo: 2.0 MT (140 hp) over 2.0 MT (136 hp) only if 4 hp and 2 Nm matter. 0–100 is 9.9 s on both, top speed 203 on both, mixed 8.5 on both, city 12.6 / highway 6.8 on both, kerb 1270 / gross 1710 on both, 3 valves per cylinder, Front, longitudinal, Distributed injection (multi-point), fuel 95. Specific output 70.2 vs 68.2 hp/l. Versus 2.0 MT (120 hp) you pay 90 kg kerb (1270 − 1180), 1.1 l/100 km mixed (8.5 − 7.4), and you gain 0.4 s and 8 km/h (10.3 → 9.9 s, 195 → 203). That is a small speed step for a real fuel and weight step.

If you want automatic: two names, not one. 2.2 AT (110 hp) is Automatic with 3 gears, 12.4 s, 183 km/h, mixed 8.3, fuel 92, 2165 cm³, Central injection (single-point or single- point). 2.9 AT (136 hp) is Automatic with 4 gears, 6 V-shaped, 2849 cm³, Distributed injection (multi-point), fuel 95; 0–100, top speed, and all three consumption figures are not measured. There is no automatic 2.0 and no automatic 2.5 MT in this record. 2.2 AT versus 2.2 MT (110 hp) is the only pair where gearbox is the sole drivetrain difference and both have a full performance set: 0.8 s, 4 km/h, 0.2 l/100 km mixed.

If you want a 2.2 and will shift yourself: 2.2 MT (110 hp) is the only 2.2 with a complete measured set (174 Nm, 11.6 s, 187 km/h, 8.1 mixed, 1220 kg). 2.2 MT (124 hp) has 8 hp more than 2.2 MT (116 hp) (124 vs 116) on the same 2180 cm³ Carburetor 80-octane recipe, and it has a measured 10.3 s; 2.2 MT (116 hp) 0–100 is not measured. Both 2180 cm³ cars leave Nm, top speed, consumption, kerb, gross, compression, bore, and engine position not measured. Fuel 80 versus 92 on the 2165 cm³ pair is a real catalogue split, not a nickname.

If you want a six-cylinder: 2.7 MT (144 hp) makes 8 hp more than 2.9 MT (136 hp) from 151 cm³ less (2700 vs 2849). Both 0–100 figures that exist are 10.0 s (2.7 MT and 2.9 MT). 2.9 MT documents V-shaped 6, 2 valves per cylinder, Front, longitudinal, Distributed injection (multi-point), compression 9.5, 91 × 73, fuel 95. 2.7 MT documents V-shaped 6 and 144 / 106 kW; valves per cylinder, position, feed, compression, bore, fuel, Nm, top speed, consumption, kerb, and gross are not measured. Specific output still favours the 2.7 (53.3 vs 47.7 hp/l). Neither six beats 2.0 MT (140 hp) on 0–100 (9.9 vs 10.0) where both are measured.

If you want the performance car: 2.5 MT (210 hp) is the only Turbo, the only 210 hp / 154 kW, the only 290 Nm, the only 7.4 s, the only 233 km/h, and the heaviest measured car at 1410 / 1870 kg. Versus 2.0 MT (140 hp): +70 hp, +114 Nm, −2.5 s, +30 km/h, +140 kg kerb, +1.1 l/100 km mixed (9.6 vs 8.5). Versus 2.0 MT (120 hp): +90 hp, −2.9 s, +38 km/h, +230 kg, +2.2 l/100 km mixed. Torque peak is 2500 rpm versus 4300–4500 on the strong 2.0 injection fours. Compression 8.1 is the lowest measured, consistent with Turbo and No on every other line.

What extra displacement does not buy. 2.9 MT (136 hp) equals 2.0 MT (136 hp) on horsepower and loses 0.1 s where both are timed (10.0 vs 9.9). 2.2 MT (110 hp) equals 2.0 MT (103 hp) on 0–100, top speed, and mixed fuel. 2.7 MT (144 hp) is only 4 hp above 2.0 MT (140 hp) with a 10.0 s time against 9.9. In this catalogue the efficient buy is a 1995 cm³ four; the fast buy is 2.5 MT; the automatic buy is 2.2 AT if you need numbers on the page, or 2.9 AT if you need 4 automatic gears and accept not-measured speed and mpg.

Reliability, known faults, and prices are not in this record; they are not measured here. Chassis, brakes, clearance, and tank do not differentiate the versions. Choose on the table: 2.0 MT (120 hp) for economy, 2.0 MT (140 hp) for the last naturally aspirated 2.0, 2.5 MT (210 hp) for turbo performance, 2.2 AT (110 hp) or 2.9 AT (136 hp) for Automatic.
