Daewoo Lacetti

Daewoo Lacetti: which version to choose

Take 1.8 MT when the measured sprint matters: 122 hp, 165 Nm, 9.5 s to 100 km/h, 194 km/h. That is the fastest 0–100 and the highest top speed in the table. Take 2.0 MT when torque is the point: 280 Nm at 2000 rpm versus 165 Nm at 4000 rpm on 1.8 MT (+115 Nm, 1800 rpm earlier). Take 1.6 MT when mixed consumption is measured and you want the same 7.1 L/100 km as 1.4 MT (92 hp) with 18 more hp.

Take 1.8 MT when the measured sprint matters: 122 hp, 165 Nm, 9.5 s to 100 km/h, 194 km/h. That is the fastest 0–100 and the highest top speed in the table. Take 2.0 MT when torque is the point: 280 Nm at 2000 rpm versus 165 Nm at 4000 rpm on 1.8 MT (+115 Nm, 1800 rpm earlier). Take 1.6 MT when mixed consumption is measured and you want the same 7.1 L/100 km as 1.4 MT (92 hp) with 18 more hp. Take 1.5 AT only if you need Automatic and Euro 3 is recorded. Do not pick 2.0 AT for speed: 12.7 s to 100 km/h is the slowest measured run.

There is no second generation in the data, so there is no later body or later powertrain to “buy into.” Differences below are arithmetic on the 12 versions shown (the generation count is 19; 12 are in this extract).

Generations (what actually changes)

1 generation (2002-11-01 to 2009-10-31): Sedan, 19 versions in the catalogue, 12 in this data. Every version below uses the same dates. Wheel sizes: not measured on all 12. CO2: not measured on all 12.

Engines and specs

Gasoline versions use 95, Distributed injection (multi-point), compression 9.5 except 1.8 MT / 1.8 AT at 9.8. Diesel 2.0 MT / 2.0 AT: compression 17.5; fuel system not measured. Rear brakes on all 12: Disc.

The three 1.4 MT cars must not be treated as one. Two make 92 hp at 6000 rpm and 130 Nm at 3400 rpm; they differ only at the front axle: Ventilated disc versus Disc. The third 1.4 MT is 95 hp at 6300 rpm and 131 Nm at 4400 rpm, Disc front. The two 1.5 MT cars both make 106 hp / 139 Nm; one is Euro 3, 1130 kg kerb, Ventilated disc front, top speed not measured; the other is 1140 kg, Disc front, 183 km/h, emissions class not measured.

Performance and economy (mpg-style figures as L/100 km)

Measured 0–100 km/h, fastest to slowest:

• 1.8 MT: 9.5 s, 194 km/h
• 2.0 MT: 9.8 s, 186 km/h (1.8 MT is 0.3 s quicker; 2.0 MT has +115 Nm)
• 1.6 MT: 10.7 s, 187 km/h (same 10.7 s as 1.8 AT)
• 1.8 AT: 10.7 s, 185 km/h (Automatic costs 1.8 MT 1.2 s and 9 km/h)
• 1.6 AT: 11.5 s, 175 km/h (Automatic costs 1.6 MT 0.8 s and 12 km/h)
• 1.4 MT (92 hp, Ventilated disc), 1.4 MT (92 hp, Disc), 1.4 MT (95 hp): all 11.6 s, 175 km/h — the 3 hp step does not change the measured sprint
• 1.5 AT: 12.2 s, 181 km/h
• 2.0 AT: 12.7 s, 188 km/h (slowest sprint; Automatic on Diesel is 2.9 s slower than 2.0 MT)

Not measured: 0–100 on both 1.5 MT versions; top speed on 1.5 MT (Euro 3, 1130 kg) only.

Mixed consumption, where measured:

• 1.4 MT (all three) and 1.6 MT: 7.1 L/100 km. City 9.3 / highway 5.9 on the 1.4s; city 9.1 / highway 6.0 on 1.6 MT. The 1.6 Manual is 18 hp and 20 Nm above the 92 hp 1.4 MT at the same mixed figure.
• 1.8 MT: 7.5 mixed (city 9.8, highway 6.2) — +0.4 mixed versus 1.6 MT for +12 hp, +15 Nm, −1.2 s, +7 km/h.
• 1.6 AT: 8.1 mixed (city 11.2, highway 6.2) — +1.0 mixed versus 1.6 MT.
• 1.8 AT: 9.1 mixed (city 12.5, highway 6.9) — +1.6 mixed versus 1.8 MT.

Not measured: city / highway / mixed on 1.5 MT (both), 1.5 AT, 2.0 MT, 2.0 AT. Diesel economy cannot be ranked from this data.

Specs: power per litre and weight per horsepower

hp per litre (displacement as given):

• 1.5 MT / 1.5 AT: 106 / 1.498 ≈ 70.8 hp/L (highest Gasoline density)
• 1.6 MT / 1.6 AT: 110 / 1.598 ≈ 68.8 hp/L

• 1.8 MT / 1.8 AT: 122 / 1.799 ≈ 67.8 hp/L
• 1.4 MT (92 hp, both brake types): 92 / 1.399 ≈ 65.8 hp/L
• 2.0 MT / 2.0 AT: 121 / 1.991 ≈ 60.8 hp/L (Diesel; torque is the other axis)

Kerb kg per hp, where kerb is measured:

• 1.8 MT: 1205 / 122 ≈ 9.88 kg/hp (lightest per hp)
• 1.5 MT (1130 kg): 1130 / 106 ≈ 10.66 kg/hp
• 1.6 MT: 1175 / 110 ≈ 10.68 kg/hp
• 2.0 MT: 1295 / 121 ≈ 10.70 kg/hp
• 1.5 MT (1140 kg): 1140 / 106 ≈ 10.75 kg/hp
• 2.0 AT: 1305 / 121 ≈ 10.79 kg/hp
• 1.4 MT (95 hp): 1170 / 95 ≈ 12.32 kg/hp
• 1.4 MT (92 hp, both): 1170 / 92 ≈ 12.72 kg/hp (heaviest per hp)

Kerb not measured: 1.6 AT, 1.8 AT. Gross not measured: 2.0 MT, 2.0 AT.

Bore × stroke (identity of the five displacements): 1.4 MT all 77.9 × 73.4; 1.5 both 76.5 × 81.5; 1.6 79 × 81.5; 1.8 81.6 × 86; 2.0 83 × 92.

Dimensions and weight

Ground clearance 160 mm and tank 60 L on all 12. Wheels: not measured.

Kerb / gross (kg):

• 1.5 MT (Euro 3): 1130 / 1645 — lightest kerb
• 1.5 MT (183 km/h): 1140 / 1645
• 1.4 MT (all three): 1170 / 1645
• 1.6 MT: 1175 / 1650
• 1.6 AT: kerb not measured / 1650
• 1.8 MT: 1205 / 1680
• 1.8 AT: kerb not measured / 1680
• 2.0 MT: 1295 / gross not measured — 125 kg heavier than 1.8 MT
• 2.0 AT: 1305 / gross not measured — 10 kg over 2.0 MT

Payload from measured pairs: 1.4 MT 1645 − 1170 = 475 kg; 1.5 MT (1130 kg) 515 kg; 1.5 MT (1140 kg) 505 kg; 1.6 MT 475 kg; 1.8 MT 475 kg. Same 475 kg on 1.4, 1.6, and 1.8 Manual; the light 1.5 MT (1130 kg) is the only one with a larger measured payload.

Manual vs Automatic (what the extra ratio set costs)

Gasoline Automatics are 4-speed; Diesel 2.0 AT is 5-speed Automatic.

• 1.6 MT → 1.6 AT: same 110 hp / 150 Nm; +0.8 s; top 187 → 175 km/h; mixed 7.1 → 8.1 L/100 km.
• 1.8 MT → 1.8 AT: same 122 hp / 165 Nm; +1.2 s; 194 → 185 km/h; mixed 7.5 → 9.1. 1.8 AT matches 1.6 MT at 10.7 s but uses 2.0 L/100 km more mixed.
• 2.0 MT → 2.0 AT: same 121 hp / 280 Nm; +2.9 s (9.8 → 12.7); top 186 → 188 km/h (Automatic is 2 km/h higher here — the only pair where Automatic is not slower on top speed). Economy not measured.
• 1.5 AT has no paired 0–100 on 1.5 MT; 1.5 AT is 12.2 s / 181 km/h, Euro 3.

If you want Automatic and a measured sprint under 12 s, the only options are 1.6 AT (11.5 s) and 1.8 AT (10.7 s). 1.5 AT and 2.0 AT are slower than 12 s.

Gasoline vs Diesel

2.0 MT is 1 hp below 1.8 MT (121 vs 122) and 0.3 s slower, with 90 kg extra kerb (1295 vs 1205). What Diesel buys is 280 Nm versus 165 Nm and peak torque at 2000 rpm versus 4000 rpm. Specific output is the lowest (60.8 hp/L) because the 1991 cc Turbo Diesel is sized for torque, not peak hp. Fuel use is not measured, so a long-distance economy case cannot be closed from this table. 2.0 AT keeps the 280 Nm but is the slowest 0–100 (12.7 s).

Reliability and problems (what the numbers can and cannot say)

No failure rates, service intervals, or defect lists are in the data. What is measured and relevant to a used-car pick:

• Front brakes: Ventilated disc on 1.4 MT (92 hp, first row), 1.5 MT (Euro 3), 1.5 AT, 1.6 MT, 1.6 AT, 1.8 MT, 1.8 AT, 2.0 MT, 2.0 AT. Disc front on the second 1.4 MT (92 hp), 1.4 MT (95 hp), and 1.5 MT (1140 kg). Same name 1.4 MT at 92 hp is two brake specs.
• Emissions class: Euro 3 only on 1.5 MT (1130 kg) and 1.5 AT; not measured on the other ten.
• All Gasoline: No boost. Only Diesel: Turbo.

Short pick list

• Fastest measured Gasoline Manual: 1.8 MT (9.5 s, 194 km/h, 7.5 mixed, 9.88 kg/hp).
• Same mixed as the 1.4s, more power: 1.6 MT (110 hp, 7.1 mixed, 10.7 s, 187 km/h).
• Automatic under 12 s: 1.8 AT (10.7 s) then 1.6 AT (11.5 s); budget mixed 9.1 vs 8.1.
• Torque / Turbo Diesel: 2.0 MT (280 Nm, 9.8 s); skip 2.0 AT if 0–100 is the test (12.7 s).
• Lightest kerb: 1.5 MT (Euro 3, 1130 kg); 0–100 not measured. 1.5 AT is the Euro 3 Automatic (12.2 s).
• Entry 1.4 MT: three cars — two at 92 hp (Ventilated disc vs Disc front) and one at 95 hp; all 11.6 s / 175 km/h / 7.1 mixed. The 95 hp car does not buy a quicker measured sprint.

There is one generation in the data. Choosing a Lacetti is choosing among these 12 rows, not among model years.
