Volkswagen Quantum: which version to buy
Two body types, two eras, the same two gasoline engines. Generation 1 (1985–1988) is a Sedan. Generation 2 (1998–2003) is an Estate 5-door. Across both, the line-up is always 1.8 MT, 1.8 AT, 2.0 MT, and 2.0 AT. Every engine is Gasoline, 4 cylinders Inline, 2 valves per cylinder, boost No, mounted Front, transverse, drive FWD.

There is no all-wheel version in this data set, so a Syncro search does not map to any listed modification.
The 1.8 litre versions share 1781 cm³, 90 hp (66 kW) at 5200 rpm, and 152 Nm at 3000 rpm. The 2.0 litre versions share 1984 cm³, 114 hp (84 kW) at 5200 rpm, and 172 Nm at 3000 rpm. That is +24 hp and +20 Nm for +203 cm³. Specific output is 90 / 1.781 ≈ 50.5 hp per litre on the 1.8 versus 114 / 1.984 ≈ 57.5 hp per litre on the 2.0.
Generations: what actually changed
1 generation (1985–1988) — Sedan, 4 versions
Kerb weight is 1125 kg on all four. Gross weight is 1585 kg on all four. Ground clearance is 150 mm. Tank is 60 litres. Front suspension is Independent, spring. Front brakes are disc. Rear suspension, rear brakes, wheel size, CO2, and eco class are not measured on the 1.8 pair; on both 2.0 versions rear suspension is Semi-independent, spring and rear brakes are Drum.
Gearboxes on this generation: 1.8 MT is Manual with 4 gears; 1.8 AT is Automatic with 3 gears; 2.0 MT is Manual with 4 gears; 2.0 AT is Automatic with 3 gears.
2 generation (1998–2003) — Estate 5-door, 4 versions
The 1.8 pair keeps kerb 1125 kg, gross 1585 kg, 150 mm clearance, 60-litre tank, the same 4-speed Manual / 3-speed Automatic split, and the same 0–100 and top-speed figures as generation 1. The estate 2.0 pair is the only place the chassis numbers move: kerb 1130 kg (+5 kg versus generation 1 2.0), gross 1655 kg (+70 kg). 2.0 MT gains a 5-speed Manual (was 4 in generation 1). 2.0 AT gains a 4-speed Automatic (was 3). Acceleration and top speed of the 2.0 stay 10.3 s and 186 km/h — extra ratios and extra payload capacity, not a quicker sprint.

Performance, mpg, and weight per horsepower
1.8 MT (both generations): 0–100 km/h in 12 s, top speed 176 km/h. City 9.4, highway 6.4, mixed 7.8 l/100 km. Kerb 1125 kg → 1125 / 90 = 12.5 kg per hp.
1.8 AT (both generations): 0–100 in 12.5 s (+0.5 s versus 1.8 MT), top speed 170 km/h (−6 km/h). City 9.8, highway 6.8, mixed 8.1 l/100 km — +0.4 / +0.4 / +0.3 l/100 km versus the manual. Same 12.5 kg per hp.
2.0 MT and 2.0 AT, generation 1: both 10.3 s and 186 km/h. Fuel city, highway, and mixed: not measured. Kerb 1125 / 114 ≈ 9.87 kg per hp. Versus 1.8 MT, that is −1.7 s to 100 km/h and +10 km/h top speed; versus 1.8 AT, −2.2 s and +16 km/h. The automatic 2.0 does not give up 0–100 or top speed to the 4-speed manual on this generation.
2.0 MT and 2.0 AT, generation 2: still 10.3 s and 186 km/h. Fuel figures not measured. Kerb 1130 / 114 ≈ 9.91 kg per hp — 0.04 kg/hp heavier than generation 1 2.0 because of the extra 5 kg. The 5-speed Manual and 4-speed Automatic do not change the published sprint or Vmax.
Wheel sizes: not measured on every version.
Dimensions and weight (buyer-relevant)
Tank 60 litres and clearance 150 mm do not change. Payload (gross minus kerb): 1585 − 1125 = 460 kg on every 1.8 and on generation 1 2.0; 1655 − 1130 = 525 kg on generation 2 2.0 MT and 2.0 AT — +65 kg of rated load on the estate 2.0.
Which version to choose
Need a wagon: only generation 2. Then pick engine and gearbox.
Need a sedan: only generation 1.
Cheapest-to-run 1.8 on paper: 1.8 MT. It is the only 90 hp car here with mixed 7.8 l/100 km and the shortest 1.8 sprint (12 s). 1.8 AT costs 0.3 l/100 km mixed, 0.5 s, and 6 km/h for a 3-speed Automatic.
Want the 2.0 power without waiting for generation 2: generation 1 2.0 MT or 2.0 AT. Same 114 hp, same 10.3 s, same 186 km/h, same 1125 kg. Gearbox is the only split: Manual 4 versus Automatic 3. Fuel use is not measured, so you cannot pick the 2.0 on mpg from this catalogue.
Want the 2.0 plus extra ratios and extra gross weight: generation 2 2.0 MT (5-speed Manual) or 2.0 AT (4-speed Automatic). You pay 5 kg kerb and still 10.3 s / 186 km/h. What the later 2.0 buys is not acceleration; it is one extra gear and +70 kg gross (525 kg payload versus 460 kg).
Do not buy a Quantum for Syncro: none of the eight versions is anything but FWD.
Do not use 1984 as a year filter against this list: production in the data starts 1985-01-01.
Engine / motor takeaway: two displacements, no turbo, no layout change. If 24 hp and 20 Nm matter more than 0.3–0.4 l/100 km on the 1.8, take a 2.0. If mixed consumption is the only measured economy you have, stay on 1.8 MT. If you need an automatic and already chose 114 hp, generation 2 2.0 AT is the only 4-speed Automatic; generation 1 2.0 AT and both 1.8 AT are 3-speed.
