Alfa Romeo 75

Generations: what actually changed between 1 generation and 1 generation, restyling

The restyling did not add a second body or a second drivetrain. What it did change, version by version:

1 generation ran 1985-01-01 to 1988-08-31. 1 generation, restyling ran 1988-09-01 to 1992-06-30. Body is Sedan in both. Ground clearance is 120 mm on every version. Wheel size is not measured on every version. CO2 and eco class are not measured throughout.

The restyling did not add a second body or a second drivetrain. What it did change, version by version:

• Fuel tank: 65 L on every 1 generation car, 68 L on every restyling car — +3 L.
• The Diesel 2.0 MT (95 hp, 70 kW, Turbo, 1995 cm³) exists only in 1 generation. After 1988-08-31 there is no Diesel line in this data.
• The 2.5 MT 156 hp (115 kW) exists only in 1 generation. Restyling keeps only 2.5 MT 154 hp.
• The carbureted 2.0 MT 128 hp exists only in 1 generation.
• Restyling adds three naturally aspirated 1.8 MT cars that the first generation does not list: 129 hp (1773 cm³, 4 valves per cylinder), 120 hp (Carburetor), and 122 hp (Distributed injection (multi-point)).
• 1.6 MT loses 3 hp at restyling: 110 hp (Carburetor, 2 valves per cylinder) becomes 107 hp (Distributed injection (multi-point); valves per cylinder not measured). Peak rpm moves from 5800 to 6000. Torque falls from 146 Nm to 137 Nm. 0–100 goes from 10.7 s to 11.3 s (+0.6 s). Top speed stays 180 km/h.
• 2.0 MT 148 hp in 1 generation is the lightest of the injected 2.0 cars at 1060 kg kerb and uses fuel grade 92; the restyling 2.0 MT 148 hp is 1200 kg kerb (+140 kg) and uses fuel grade 95. Same 8.2 s and 205 km/h, but 8.11 kg/hp versus 7.16 kg/hp. Combined consumption on the first-generation 148 hp car is not measured; the restyling twin is 8.4 L/100 km combined.

Identical across both generations (same hp, same 0–100 where measured, same layout labels): 1.8 MT 116 hp Carburetor; 1.8 MT 150 hp Turbo; 1.8 MT 155 hp Turbo; 2.0 MT 146 hp; 2.5 MT 154 hp; 3.0 MT 185 hp. On those, the restyling mainly buys the 68 L tank versus 65 L.

1 generation, restyling lists 3.0 MT twice: both 185 hp, 136 kW at 5800 rpm, 245 Nm at 3000 rpm, 2959 cm³, 6 V-shaped, 2 valves per cylinder, boost No, 7.3 s, 220 km/h, kerb 1300 kg, gross 1725 kg. The two rows do not differ in any measured field in this data.

Engines and specs

All petrol versions are labelled Gasoline. Cylinder counts in the data are 4 Inline or 6 V-shaped. Gearbox is Manual 5. Drive is RWD. Boost is No except Turbo on the 1.8 MT 150 hp, 1.8 MT 155 hp, and Diesel 2.0 MT.

1 generation, restyling (1988-09-01 – 1992-06-30)

Feed on restyling: 1.6 MT 107 hp, 1.8 MT 129 hp, 1.8 MT 122 hp, both Turbos, both 2.0 MT, 2.5 MT, and both 3.0 MT use Distributed injection (multi-point). 1.8 MT 116 hp and 1.8 MT 120 hp use Carburetor. Engine position is Front, transverse only on 1.8 MT 155 hp; not measured on the others.

1 generation (1985-01-01 – 1988-08-31)

Feed on first generation: Carburetor on 1.6 MT 110 hp, 1.8 MT 116 hp, 2.0 MT 128 hp. Distributed injection (multi-point) on both Turbos, 2.0 MT 146 hp, 2.0 MT 148 hp, both 2.5 MT, 3.0 MT. Diesel 2.0 MT feed is not measured. Engine position Front, transverse is listed on 1.6 MT 110 hp, 1.8 MT 155 hp, and 2.0 MT 148 hp; not measured on the rest.

Fuel grade (English labels): 92 on the small petrol cars listed with a grade; 95 on the Turbos at 150 hp, the 2.0 MT 146 hp cars, 2.5 MT, and 3.0 MT; Diesel on Diesel 2.0 MT. 1.6 MT 107 hp fuel grade is not measured. Compression is 10.3 on restyling 1.8 MT 129 hp (bore × stroke 82 × 75.6); 9 on both 1.8 MT Carburetor 116 hp cars and restyling 120 hp; 10 on 2.0 MT 128 / 146 / 148 hp (where listed) and 2.5 MT; 9.5 on 3.0 MT. Bore × stroke 84 × 90 is listed on first-generation 2.0 MT 128 hp; 88 × 68.3 on 2.5 MT 154 hp and 156 hp. Elsewhere compression and bore are not measured.

Power per litre (hp ÷ displacement in litres): 1.8 MT 155 hp 87.1; 1.8 MT 150 hp 84.3; restyling 2.0 MT 148 hp 75.4; 2.0 MT 146 hp 74.4; restyling 1.8 MT 129 hp 72.8; first-generation 1.6 MT 70.1; restyling 1.6 MT 68.2; restyling 1.8 MT 122 hp 68.6; restyling 1.8 MT 120 hp 67.5; 1.8 MT 116 hp 65.2; first-generation 2.0 MT 128 hp 65.2; 3.0 MT 62.5; 2.5 MT 156 hp 62.6; 2.5 MT 154 hp 61.8; Diesel 2.0 MT 47.6. Turbo on 1779 cm³ is the density play; the 6 V-shaped cars make more total hp with less hp per litre.

Performance and economy (mpg / L/100 km)

• First-generation 1.6 MT: 10.7 s, 180 km/h.
• Restyling 1.6 MT: 11.3 s, 180 km/h.
• Diesel 2.0 MT: 12.4 s, 175 km/h — slowest and lowest top speed.

Not measured: 0–100 and top speed on restyling 1.8 MT 129 hp. Peak power rpm and both torque figures on both 1.8 MT 150 hp Turbos.

Combined consumption, where measured (L/100 km): Diesel 2.0 MT 7.2 (city 8.7, highway 5.3) is the lowest. Next is 2.0 MT 146 hp (and restyling 148 hp) at 8.4 (city 9.9, highway 6.0). Restyling 1.6 MT 107 hp, restyling 1.8 MT 120 hp, and restyling 1.8 MT 122 hp share 8.9 combined; the 107 hp car is city 10.0 / highway 6.7, the 120/122 hp cars city 10.5 / highway 6.9. 1.8 MT 116 hp is 9.2 (city 12.2, highway 7.2) — +3.3 L/100 km in the city versus restyling 1.6 MT. 2.5 MT and 3.0 MT share 9.4 combined; city is 13.2 vs 12.9, highway 7.6 vs 7.4. Combined, city, and highway are not measured on: restyling 1.8 MT 129 hp, both 150 hp and 155 hp Turbos, first-generation 1.6 MT, first-generation 2.0 MT 148 hp.

Range arithmetic on the 68 L restyling tank at combined figures: 68 / 8.4 × 100 ≈ 810 km on 2.0 MT 146/148 hp; 68 / 8.9 × 100 ≈ 764 km on 1.6 MT 107 hp; 68 / 9.4 × 100 ≈ 723 km on 2.5 MT / 3.0 MT. On the 65 L first-generation tank: Diesel 65 / 7.2 × 100 ≈ 903 km; 2.0 MT 146 hp 65 / 8.4 × 100 ≈ 774 km; 3.0 MT 65 / 9.4 × 100 ≈ 691 km.

Dimensions and weight

Ground clearance 120 mm on all. Tank 65 L then 68 L. Wheels not measured.

3.0 MT is 240 kg heavier than the 1060 kg base cars (+22.6%) for +78 hp versus restyling 1.6 MT (185 − 107). 1.8 MT 155 hp at 1070 kg is only 10 kg above that base and 230 kg below 3.0 MT, with 30 hp less than 3.0 MT and the same 7.6 s versus 7.3 s.

kg/hp: 1.8 MT 155 hp 6.90; 2.5 MT 156 hp 6.99; 3.0 MT 7.03; 2.5 MT 154 hp 7.08; first-generation 2.0 MT 148 hp 7.16; 1.8 MT 150 hp 7.67; 2.0 MT 146 hp 7.95; restyling 2.0 MT 148 hp 8.11; restyling 1.8 MT 129 hp 8.22; first-generation 2.0 MT 128 hp 8.36; restyling 1.8 MT 120 hp 8.83; restyling 1.8 MT 122 hp 8.85; 1.8 MT 116 hp 9.14; first-generation 1.6 MT 9.64; restyling 1.6 MT 9.91; Diesel 2.0 MT 12.53.

Suspension: most cars are front Independent, spring and rear Dependent, spring. Rear Independent, spring is listed on 1.8 MT 155 hp (both generations), first-generation 1.6 MT, and first-generation 2.0 MT 148 hp. Brakes are Disc front and rear on every version (label as in the data).

Which version to choose

Buy 1.8 MT 155 hp Turbo if the question is power density and mass. 155 hp from 1779 cm³ is 87.1 hp/L; kerb 1070 kg is 6.9 kg/hp; 0–100 7.6 s; top speed 209 km/h; 225 Nm at 2600 rpm is the lowest torque peak rpm in the petrol set. Fuel grade 92. Boost Turbo, 4 valves per cylinder, Distributed injection (multi-point), rear Independent, spring. Combined consumption not measured. The same spec exists in 1 generation (65 L tank) and restyling (68 L). Restyling is the later window (1988-09-01–1992-06-30).

Buy 3.0 MT 185 hp if the question is peak power and peak speed. 185 hp, 245 Nm at 3000 rpm, 7.3 s, 220 km/h, 6 V-shaped. You carry 1300 kg kerb and 1725 kg gross — 230 kg more kerb than 1.8 MT 155 hp for +30 hp, +0.3 s to 100, +11 km/h. Combined 9.4 L/100 km versus not measured on the Turbo. Two restyling 3.0 MT rows are numerically the same 185 hp cars.

Buy 1.8 MT 150 hp Turbo only if you accept 80 kg extra kerb versus the 155 hp Turbo (1150 vs 1070 kg) for 5 hp less, the same 7.6 s, and 210 km/h (+1 km/h). Torque, torque rpm, and power rpm are not measured. Fuel grade 95 versus 92 on the 155 hp car. Gross weight not measured.

Do not assume 2.5 MT is quicker than 2.0 MT. 2.5 MT 154 hp and 2.0 MT 146 hp / 148 hp all post 8.2 s and, except 156 hp, 205 km/h. 2.5 MT 156 hp only adds 4 km/h (209). Combined 9.4 versus 8.4 on the injected 2.0 MT 146 hp. 2.5 MT is 1090 kg — lighter than 2.0 MT 146 hp at 1160 kg, but city use is 13.2 vs 9.9 L/100 km. Choose 2.5 MT 156 hp only in 1 generation if you want the extra 2 hp over 154 hp; restyling has no 156 hp row.

Buy restyling 2.0 MT 146 hp (or first-generation 2.0 MT 146 hp) if you want the best measured petrol combined figure among cars that also have a full 0–100: 8.4 / 9.9 / 6.0, 8.2 s, 205 km/h, 146 hp, fuel 95. The restyling 2.0 MT 148 hp matches the times but is 1200 kg (+40 kg vs 146 hp restyling, +140 kg vs first-generation 148 hp at 1060 kg). First-generation 2.0 MT 148 hp is the light injected 2.0 (7.16 kg/hp) with fuel 92, but combined consumption not measured.

Buy first-generation 2.0 MT 128 hp if you want Carburetor, 1962 cm³, 128 hp, 8.9 s, 196 km/h, 1070 kg, combined 8.4. Versus injected 146 hp you lose 18 hp, 0.7 s, and 9 km/h, and you stay on Carburetor. It is not in restyling.

Among 1.8 MT naturally aspirated cars, the 116 hp Carburetor is the quicker measured car, not the 122 hp injection car. 1.8 MT 116 hp: 9.5 s, 190 km/h, 1060 kg, combined 9.2, city 12.2. Restyling 1.8 MT 120 hp: same 9.5 s, 193 km/h, city 10.5 (−1.7 vs 116 hp), combined 8.9. Restyling 1.8 MT 122 hp: 10.4 s, 190 km/h, 1080 kg. Restyling 1.8 MT 129 hp: 129 hp, 4 valves per cylinder, 1773 cm³, compression 10.3, 72.8 hp/L, 1060 kg — but 0–100, top speed, and all three consumption figures are not measured. If you need a measured sprint, do not pick the 129 hp row on numbers you do not have.

Buy 1.6 MT only as the lightest, lowest-power petrol. First-generation 1.6 MT 110 hp is the better of the two on paper: +3 hp, +9 Nm, 10.7 s vs 11.3 s, Carburetor, fuel 92. Restyling 1.6 MT 107 hp adds injection and the 68 L tank and is the only 1.6 MT with measured consumption (8.9 / 10.0 / 6.7). Both 1060 kg, both 180 km/h.

Buy Diesel 2.0 MT 95 hp only in 1 generation, and only if consumption is the ranking axis. 7.2 / 8.7 / 5.3, ≈903 km on 65 L, 193 Nm at 2300 rpm. Cost in the data: 95 hp, 12.4 s, 175 km/h, 1190 kg, 12.53 kg/hp. It disappears in restyling.

Generation pick when the engine is the same: take restyling for +3 L tank and the later production window; take 1 generation if you need Diesel 2.0 MT, 2.5 MT 156 hp, 2.0 MT 128 hp, or the light 2.0 MT 148 hp at 1060 kg. Reliability, prices, and options are not measured in this data; the ranking above is only hp, kg, seconds, km/h, and L/100 km as listed.
