Chevrolet Optra: which version to buy
If you are choosing a Chevrolet Optra rather than reading a catalogue overview, the data set is small and the differences are arithmetic. There is one generation (February 2004–November 2013), Sedan only, and four listed versions: two named 1.6 AT (both 109 hp), one 1.6 MT (109 hp), and one 1.8 AT (122 hp).
If you are choosing a Chevrolet Optra rather than reading a catalogue overview, the data set is small and the differences are arithmetic. There is one generation (February 2004–November 2013), Sedan only, and four listed versions: two named 1.6 AT (both 109 hp), one 1.6 MT (109 hp), and one 1.8 AT (122 hp). Production in this data ends in November 2013, so searches for Chevrolet Optra 2025, Chevrolet Optra 2026, 2025 specs, or 2026 horsepower do not match a later generation here — they still map to this 2004–2013 sedan. There is no Chevrolet Optra LS trim, no Magnum horsepower figure, no price, and no engine-for-sale listing in the source.
The buy decision is therefore not “which generation.” It is 1.6 vs 1.8, and Automatic vs Manual on the 1.6.
Chevrolet Optra specs by version (what you actually compare)
All four versions are Gasoline, 4 Inline cylinders, 4 valves per cylinder, Front, transverse, Direct injection (direct), FWD, 60 L tank, Independent, spring front and rear, Disc front / Drum rear, 92-octane fuel.
| Version | hp (kW @ rpm) | Nm @ rpm | cc | Boost | Gearbox | 0–100 | Top speed |
|---|---|---|---|---|---|---|---|
| 1.6 AT | 109 (80 @ 5800) | 153 @ 4000 | 1598 | not measured | Automatic 4 | 11.5 s | not measured |
| 1.6 AT | 109 (80 @ 5800) | 153 @ 4000 | 1598 | not measured | Automatic 4 | 11.5 s | not measured |
| 1.8 AT | 122 (89 @ 5800) | 165 @ 4000 | 1799 | No | Automatic 4 | 10.7 s | 185 km/h |
| 1.6 MT | 109 (80 @ 5800) | 153 @ 4000 | 1598 | not measured | Manual 5 | not measured | not measured |
The two 1.6 AT rows are the same on every measured field in this data (109 hp, 80 kW, 153 Nm, 1598 cc, 11.5 s, Automatic 4, FWD). You cannot split them by power the way two differently rated engines with one name would split. Treat them as one automatic 1.6 specification listed twice.
Chevrolet Optra engine: 1.6 vs 1.8 (horsepower, cc, what the extra displacement buys)
Engine capacity. 1.6 AT / 1.6 MT use 1598 cc. 1.8 AT uses 1799 cc — 201 cc more (+12.6%).
Horsepower. 109 hp vs 122 hp is +13 hp on the 1.8 (+11.9%). In kW that is 80 vs 89 (+9 kW, +11.3%). Peak power rpm is the same: 5800 on every version.
Torque. 153 Nm vs 165 Nm is +12 Nm on the 1.8 (+7.8%). Peak torque rpm is the same: 4000 on every version.
Specific output (arithmetic on the given numbers).
- 1.6 (109 hp / 1.598 L) ≈ 68.2 hp/L; 80 kW / 1.598 L ≈ 50.1 kW/L; 153 Nm / 1.598 L ≈ 95.7 Nm/L.
- 1.8 AT (122 hp / 1.799 L) ≈ 67.8 hp/L; 89 kW / 1.799 L ≈ 49.5 kW/L; 165 Nm / 1.799 L ≈ 91.7 Nm/L.
The 1.8 is larger and stronger in absolute hp and Nm; it is not a higher-output-per-litre engine. You pay (in displacement and, where measured, in fuel) for more cubic centimetres, not for a denser tune. Compression ratio is 9.8 and bore × stroke 81.6 × 86 on 1.8 AT only; both figures are not measured on 1.6 AT and 1.6 MT. Boost on 1.8 AT is No; boost on both 1.6 versions is not measured.
Chevrolet Optra 2004 / 2005 / 2006 / 2007 / 2008 / 2009 / 2012 engine specs in this catalogue are the same four rows: the generation does not change engine figures by calendar year in the data. A 2006 1.6 AT and a 2012 1.6 AT are the same 109 hp / 153 Nm / 1598 cc specification here.
Performance: 0–100 and top speed
1.8 AT is the only version with both a 0–100 time and a top speed: 10.7 s and 185 km/h.
1.6 AT (both listings): 11.5 s to 100 km/h; top speed not measured. Versus 1.8 AT, that is 0.8 s slower (11.5 − 10.7). The 1.8’s extra 13 hp and 12 Nm show up as that 0.8 s, not as a different gearbox: both automatics are Automatic with 4 gears.
1.6 MT: 0–100 not measured, top speed not measured. You cannot claim the five-speed Manual is quicker or slower than the four-speed Automatic from this data. You can only say it has one extra gear (5 vs 4) and the same 109 hp / 153 Nm engine as 1.6 AT.
If the question is “which Optra is fastest in the measured set,” the answer is 1.8 AT. If the question is “is the 1.6 MT faster than the 1.6 AT,” the answer is not measured.
Fuel consumption (mpg-style figures as given, L/100 km)
Only 1.8 AT has economy numbers: city 12.5, highway 6.9, mixed 9.1 L/100 km. 1.6 AT (both) and 1.6 MT: city, highway, and mixed are all not measured. CO2 and eco class are not measured on every version.
You cannot pick the 1.6 as “the economical one” from these numbers, because its consumption was not recorded. You can say that the only Optra whose mixed figure exists is the 122 hp 1.8 AT at 9.1 L/100 km, with a 60 L tank on every version.
Chevrolet Optra weight in kg, tank, dimensions
Kerb weight: 1.6 AT (both listings) 175 kg; 1.8 AT not measured; 1.6 MT not measured. Gross weight: 1.8 AT 1680 kg; both 1.6 AT and 1.6 MT not measured. Ground clearance: not measured on all four. Wheel sizes: not measured on all four. Tank: 60 L on all four.
Chevrolet Optra dimensions / size / 2006 dimensions / 2026 dimensions are not measured in this data. There is no length, width, height, or wheelbase to compare between versions.
Weight per horsepower can be computed only where both mass and power exist:
- 1.6 AT: 175 kg / 109 hp ≈ 1.61 kg/hp (kerb). That pair is what the source gives; it is not comparable to the 1.8 because the 1.8 has no kerb weight.
- 1.8 AT: 1680 kg gross / 122 hp ≈ 13.8 kg/hp on gross mass — a different kind of mass, so do not rank 1.6 against 1.8 on kg/hp. The 1.6 has no gross weight.
For a buyer: tank size does not decide the version (60 L across the board). Ground clearance and wheels do not decide it (not measured). Weight decides nothing between 1.6 MT and 1.8 AT because kerb is missing there.
Automatic vs Manual on the 1.6 (same engine, different box)
1.6 AT and 1.6 MT share: 109 hp, 80 kW @ 5800, 153 Nm @ 4000, 1598 cc, Gasoline, 4 Inline, Direct injection (direct), FWD, 92 fuel, 60 L tank, same suspension and brakes.
They differ on:
- gearbox: Automatic 4 vs Manual 5;
- 0–100: 11.5 s vs not measured;
- kerb weight: 175 kg vs not measured.
If you want a measured 0–100 on a 1.6, that is 1.6 AT at 11.5 s. If you want five gears and a Manual, that is 1.6 MT, with acceleration not measured. There is no 1.8 Manual in the data: the 122 hp engine is tied to Automatic 4 only.
Which Chevrolet Optra version to choose
Choose 1.8 AT if the numbers you care about are peak power, torque, and a recorded top speed. You get 122 hp / 165 Nm / 1799 cc, 10.7 s 0–100, 185 km/h, mixed 9.1 L/100 km, gross 1680 kg, compression 9.8, and 81.6 × 86. Versus 1.6 AT that is +13 hp, +12 Nm, +201 cc, −0.8 s to 100. Specific output is slightly lower (≈67.8 vs ≈68.2 hp/L), so you are buying capacity, not a hotter 1.6.
Choose 1.6 AT if you want the smaller engine with a measured 0–100 (11.5 s) and an Automatic 4, and you accept top speed, consumption, gross weight, clearance, and wheels as not measured. Both 1.6 AT listings are 109 hp; there is no 109-vs-something split under that name.
Choose 1.6 MT if the gearbox is the point: Manual 5, same 109 hp / 153 Nm / 1598 cc as the automatic 1.6. Do not pick it for a claimed sprint or economy figure — both are not measured.
Do not choose by generation, model year badge, or 2025/2026 specs. This catalogue has one generation (2004–2013), one body (Sedan), and the same four version names for 2004, 2006, 2008, 2009, and 2012 searches. Chevrolet Optra price, engine oil capacity, engine number location, engine mount, and engines for sale are not in the data and are not a basis for picking a version here.
Short ranking on measured fields only: fastest and most powerful — 1.8 AT; only 1.6 with a timed 0–100 — 1.6 AT; only Manual — 1.6 MT; no version has a measured advantage on clearance, wheels, or dimensions.
