Alfa Romeo Giulia is listed as 4 generations. Dates, body, and version counts:

From 1 generation to 2 generation the layout flips: FWD Cabrio to a rear- or all-wheel sedan, Manual 4- or 5-speed to Automatic 8 or Manual 6, peak power 102 hp to 510 hp, kerb 998–1130 kg to 1374–1695 kg, clearance 165 mm to 100 mm. Top speed 138–185 km/h versus 210–307 km/h.

2 generation, restyling versus 2 generation is not a power jump on the shared petrol cores: 2.0 AT 200 hp still 336 Nm, 6.6 s, 235 km/h; 2.0 AT 280 hp still 5.2 s and 240 km/h; 2.9 still 510 hp and 3.9 s / 307 km/h. The diesel line is renamed 2.1 → 2.2 AT (same 2143 cm³) and the 136 / 150 / 180 hp Manual and Automatic diesels disappear. Estrema trims appear. Diesel tank is 52 L on restyling 2.2 AT versus 58 L on 2 generation 2.1 diesels.

2 generation, restyling 2 overlaps the first restyling from 2022-10-01. Four versions only. Engine position is Front, transverse on 2.2 AT 210 hp AWD, 2.2 AT 160 hp RWD, and 2.0 AT 280 hp AWD; 2.9 AT Quadrifoglio stays Front, longitudinal. Fuel on petrol is 95, not 98. 2.9 AT Quadrifoglio is 520 hp / 382 kW versus 510 hp / 375 kW on earlier 2.9. 0–100, top speed, mpg, CO2, eco class, and kerb are not measured on three of the four restyling-2 cars.

You give up restyling-era 210 hp: 136 hp is 74 hp below 2.2 AT 210 hp; 0–100 is 9.0 s versus 6.8 s (2.2 s slower). 2.1 AT 180 hp RWD is 7.1 s, still 0.3 s slower than 210 hp, with the same 4.2 mixed figure.

Daily diesel after 2020: restyling 2.2 AT 210 hp RWD — 6.8 s, 235 km/h, 4.7 mixed, 122 g/km, 52 L tank (6 L less than 2.1). 2.2 AT Estrema matches those numbers; the measured difference is Independent, pneumatic versus Independent, spring. Restyling-2 2.2 AT 210 hp AWD adds AWD and Front, transverse; 0–100 is 6.8 s, consumption not measured. Restyling-2 2.2 AT 160 hp is 50 hp below the 210 (24% less); 0–100, top speed, mpg, weight not measured.

Lightest petrol sedan in the restyling list: 2.0 AT 200 hp — 1504 kg, 80 hp and 101 kg below restyling 2.0 AT 280 hp RWD, 1.4 s slower (6.6 vs 5.2), 5 km/h lower top speed (235 vs 240), mixed 5.9 vs 6.4 (0.5 L/100 km less), CO2 138 vs 194.

280 hp petrol: three restyling cars share 280 hp / 408 Nm / 5.2 s / 240 km/h / 6.4 mixed: 2.0 AT Estrema (RWD, pneumatic, CO2 194), 2.0 AT 280 hp RWD (spring, CO2 194), 2.0 AT 280 hp AWD (spring, CO2 152, gross 2105, wheels 255/40 R18 and 225/45 R18). AWD does not change listed 0–100. 2 generation 2.0 AT 280 hp AWD is 1429 kg with 400 Nm (8 Nm below restyling 408) and 206 kW versus 205 kW; 2.0L AT is the RWD 280 name in that generation.

Halo 2.9: 2.9 AT AWD 612 Nm, mixed 8.2, city 12.4, highway 5.7, 1695 kg; 2.9 AT RWD 600 Nm, mixed 9.2, city 11.9, highway 7.6, 1620 kg, wheels 285/30 R19 and 245/35 R19. Same 510 hp, 3.9 s, 307 km/h. AWD is 75 kg heavier, 12 Nm more, 1.0 L/100 km lower mixed, 2.5 g? wait 189 vs 214 CO2 (25 g/km less). 2.9L matches the AWD Automatic 612 Nm / 8.2 mixed set in 2 generation. 2.9 MT is the only 6-speed Manual 510: 1580 kg (lightest 2.9), mixed 8.5, 198 g/km. 2.9 AT Quadrifoglio is the only 520 hp listing; mixed 8.2 like AWD 510, RWD like the 600 Nm car, kerb 1695 like AWD 510.

Cabrio only in 1 generation. Fastest listed top speed there is 1.6 MT 102 hp at 185 km/h; 1.8 MT diesel 55 hp is 138 km/h. 1.6 MT 98 hp is the lightest measured Giulia in the whole file at 998 kg (10.18 kg/hp). 1.3 MT 89 hp versus 1.3 MT 82 hp: +7 hp, −1 Nm (104 vs 105), same 160 km/h.

What extra power buys (restyling 2.0 200 → 280): +80 hp, +72 Nm, −1.4 s to 100, +5 km/h, +0.5 mixed, +101 kg, +56 g/km CO2 on RWD. What 2.9 adds over 280 RWD: +230 hp, +192 or +204 Nm, −1.3 s, +67 km/h, +1.8 to +2.8 mixed, +15 to +90 kg.

Problems and reliability: not measured in these data. Fuel grade, injection, and eco class gaps are listed as not measured above; they are missing measurements, not proof that the car has no fuel grade or no eco class.

Short pick: 2.1 AT 180 hp or 2.2 AT 210 hp for measured economy; 2.0 AT 200 hp for the lightest restyle petrol; 2.0 AT 280 hp AWD if 5.2 s plus AWD; 2.9 AT Quadrifoglio if 520 hp is the requirement; 2.9 MT if Manual 6 and 3.10 kg/hp; 1.6 MT 102 hp if the Cabrio years are the requirement.
