Alfa Romeo GT

Which Alfa Romeo GT to buy: 1.8 MT, 1.9 MT, 2.0 MT, 2.0 TCT or 3.2 MT

The Alfa Romeo GT ran as 1 generation from 2003-01-01 to 2010-01-31, always as a Coupe, with 6 versions on one platform. There is no second generation to “wait for,” and no restyling listed as a separate generation. The buying question is which of the six powertrains to live with: 1.8 MT (140 hp), 1.9 MT (150 hp), 1.9 MT (170 hp), 2.0 TCT (165 hp), 2.0 MT (165 hp), or 3.2 MT (240 hp).

Wheel size is not measured. CO2 is not measured on every version. Eco class is Euro 4 on the 1.8 and both 1.9 diesels, and not measured on both 2.0 petrols and the 3.2.

People looking up GTV, GTV6, GTA, GTAm, Giulia GT, GT Junior, GT Ultimate or Q2 will not find those names in this catalogue row. This article is the 2003–2010 Coupe GT and the six names above.

Generations: what actually changed (one generation)

1 generation (2003-01-01–2010-01-31), Coupe, 6 versions. Every listed version shares the same start and stop dates, 140 mm ground clearance, a 63 L tank, Independent, spring suspension front and rear, and Disc brakes at both ends. What changes between “which GT to buy” is engine, gearbox, mass and the 0–100 / top-speed / consumption set — not a later body or a later generation.

Alfa Romeo GT engine options and specs

Power per litre (hp ÷ displacement in litres) and kerb kg per hp are arithmetic on the catalogue numbers.

1.8 MT is the only naturally aspirated 1747 cc unit: 140 hp (103 kW) at 6500 rpm, 163 Nm at 3900 rpm, compression 10.3, bore × stroke 82 × 82.7, Distributed injection (multi-point), engine Front, transverse, fuel 95.

The two 1.9 MT diesels share 1910 cc, Turbo, 4 Inline, 4 valves per cylinder, compression 18.5, 82 × 90.4, fuel Diesel. Engine position and injection system are not measured on both. Distinguish them by power: 150 hp (110 kW) at 4000 rpm with 305 Nm at 2000 rpm, versus 170 hp (125 kW) with rpm and torque not measured.

2.0 TCT and 2.0 MT share the same 1970 cc Gasoline four: 165 hp (121 kW) at 6400 rpm, 206 Nm at 3250 rpm, No boost, Direct injection (direct), compression 11.3, 83 × 91, Front, transverse, fuel 95. The split is gearbox: Robotic, 6 versus Manual, 5.

3.2 MT is the only 6-cylinder: 3179 cc Gasoline, V-shaped, 240 hp (176 kW) at 6200 rpm, 300 Nm at 4800 rpm, No boost, Distributed injection (multi-point), compression 10.1, 93 × 78, Front, transverse, Manual, 6, fuel 95. It has the lowest specific output (75.5 hp/L) and the lowest kerb mass per horsepower (5.88 kg/hp).

Length, width and wheelbase are not measured. Weight distribution is not measured.

Performance, mpg and what the extra power costs in fuel

1.8 MT → 2.0 MT: +25 hp, 0–100 faster by 1.9 s, top speed +16 km/h, mixed use +0.2 L/100 km. The 2.0 pair matches the 170 hp 1.9 MT on top speed (216) but is 0.5 s slower to 100 and uses 2.5 L/100 km more mixed.

1.9 MT 150 hp → 1.9 MT 170 hp: +20 hp on the same 1910 cc Turbo diesel. 0–100 improves by 1.4 s (9.6 → 8.2). Top speed +7 km/h. City use is identical at 8.7. Highway drops 0.6 L (5.4 → 4.8); mixed drops 0.5 L (6.7 → 6.2). Torque is published only for the 150 hp car (305 Nm at 2000 rpm); for the 170 hp car torque is not measured.

2.0 MT versus 2.0 TCT: identical 0–100 (8.7 s), top speed (216) and all three consumption figures. The robotic six-speed does not buy a measured speed or economy gain over the five-speed manual on this data.

2.0 MT → 3.2 MT: +75 hp, 0–100 faster by 2.0 s, top speed +27 km/h, mixed use +3.7 L/100 km (8.7 → 12.4). Versus the 170 hp 1.9 MT, the 3.2 is 1.5 s quicker to 100 and 27 km/h faster at the top, at +6.2 L/100 km mixed (12.4 vs 6.2) — twice the mixed figure plus 0.0 leftover (12.4 / 6.2 = 2.0).

3.2 MT versus 1.8 MT: +100 hp, 3.9 s off 0–100, +43 km/h top speed, mixed +3.9 L/100 km. City use on the 3.2 (18.6) is 6.5 L above the 1.8 (12.1) and 9.9 L above either 1.9 diesel (8.7).

Highway ranking, lowest first: 1.9 MT 170 hp 4.8 → 1.9 MT 150 hp 5.4 → 1.8 MT 6.4 → 2.0 MT / 2.0 TCT 6.8 → 3.2 MT 8.7. Mixed ranking is the same order except the two 2.0s sit 0.2 L above the 1.8.

Dimensions, weight and tank (what the scales actually say)

Length, width, height, wheelbase and tyre size: not measured for every version.

Lightest kerb is 1.8 MT at 1295 kg — 30 kg under 2.0 MT (1325), 70 kg under the diesels and 2.0 TCT (1365), 115 kg under 3.2 MT (1410). Highest gross is the 2.0 pair at 1840 kg. Highest payload is a tie: 1.8 MT and 2.0 MT at 515 kg. Tightest payload is 3.2 MT at 340 kg — 175 kg less than the 1.8 / 2.0 MT, because kerb rose 115 kg while gross fell 60 kg versus the 1.8 (1810 → 1750). Both diesels share the 3.2’s 1750 gross at 1365 kerb, so payload is 385 kg.

2.0 TCT is 40 kg heavier at kerb than 2.0 MT (1365 vs 1325) with the same 1840 gross, so the robotic car’s payload is 475 kg, 40 kg less than the manual 2.0. kg/hp on 2.0 MT matches the 170 hp 1.9 MT at 8.03; 2.0 TCT is worse at 8.27 solely because of that 40 kg.

Ground clearance does not help you choose: 140 mm on all six.

Which version to choose

Buy 1.8 MT if you want the lowest kerb (1295 kg), the highest payload tied with 2.0 MT (515 kg), Euro 4, and the cheapest mixed petrol use among the gasoline cars (8.5). You accept the slowest 0–100 (10.6 s) and the lowest top speed (200). Peak torque arrives late (3900 rpm) and is the smallest number in the table (163 Nm) — 142 Nm below the 150 hp diesel’s 305 Nm.

Buy 1.9 MT (150 hp) if you want published low-rpm torque (305 Nm at 2000 rpm), a 6-speed Manual, Euro 4, and mixed use of 6.7 without stepping to the 170. Versus 1.8 MT you gain 10 hp, 1.0 s to 100, 9 km/h on top speed, and 1.8 L/100 km mixed, at +70 kg kerb and −130 kg payload (515 → 385). Specific output (78.5 hp/L) is actually 1.6 hp/L below the 1.8.

Buy 1.9 MT (170 hp) if diesel is acceptable and you want the best measured economy and the strongest four-cylinder sprint in this list. It is the highest hp/L here (89.0), matches 2.0 MT on kg/hp (8.03) and on top speed (216), and beats both 2.0s to 100 by 0.5 s (8.2 vs 8.7) while using 2.5 L/100 km less mixed. Versus the 150 hp 1.9 MT you pay nothing extra in city fuel (8.7 both) and gain 1.4 s / 7 km/h. The gap you must accept: torque and power rpm are not measured on this 170 hp row, and payload stays the diesel 385 kg.

Buy 2.0 MT if you want petrol, Direct injection (direct), 165 hp, and the same 0–100 / top speed as 2.0 TCT without the robotic box. Versus 1.8 MT: +25 hp, −1.9 s, +16 km/h, +30 kg kerb, same 515 kg payload, mixed +0.2 L. Versus 1.9 MT 170 hp: same 216 km/h, 0.5 s slower, +2.5 L mixed, +130 kg payload (515 vs 385), and you keep a published 206 Nm at 3250 rpm. Eco class is not measured. Gearbox is Manual, 5, not 6.

Buy 2.0 TCT if the Robotic, 6 is the point. On 0–100, top speed and L/100 km it is a duplicate of 2.0 MT. What you do not get: a faster sprint, a higher top speed, or lower fuel use. What you do get: +40 kg kerb and −40 kg payload versus 2.0 MT. Eco class is not measured.

Buy 3.2 MT if the catalogue job is maximum hp and minimum seconds: 240 hp, 6.7 s, 243 km/h, 300 Nm, 6-speed Manual, 6 cylinders V-shaped. Versus 2.0 MT that is +75 hp, −2.0 s, +27 km/h. Versus 1.9 MT 170 hp: +70 hp, −1.5 s, +27 km/h. The bill in the same units: heaviest kerb (1410 kg), smallest payload (340 kg), highest mixed (12.4), shortest mixed tank range (508 km on 63 L), lowest hp/L (75.5). Eco class is not measured. It is still FWD; drive type does not change with the 3179 cc engine.

If the search was GTV / GTV6 / GTA / GTAm / Junior / Giulia GT / Q2 / Ultimate: those labels are not versions in this data. The closest “GT 3.2 specs / GT 3.2 weight” match is 3.2 MT at 240 hp, 1410 kg kerb, 1750 kg gross. The closest “GT engine options” set is the six rows in the table. Engine-bay, engine-mount, engine-swap, motor-control-failure and Ferrari-motor topics are not measured here.

Short rule from the arithmetic only: 1.9 MT (170 hp) wins economy and four-cylinder 0–100; 2.0 MT wins petrol-with-payload; 1.8 MT wins lightest kerb; 3.2 MT wins hp, 0–100 and top speed; 2.0 TCT is 2.0 MT plus 40 kg; 1.9 MT (150 hp) is the only diesel with a published 305 Nm at 2000 rpm.
