Chery QQ6 (S21): which version to buy — 1.1 MT vs 1.3 MT

If you are choosing a Chery QQ6 (S21), the catalogue has one generation and two named versions: 1.1 MT and 1.3 MT. Both are Liftback, Gasoline, Inline 4, Front, transverse, Manual 5, FWD, built from 2006-01-01 to 2011-05-31. The buy decision is not “which generation” — there is only 1 generation. It is which engine: 1083 cm³ / 68 hp versus 1297 cm³ / 83 hp.

Both are Liftback, Gasoline, Inline 4, Front, transverse, Manual 5, FWD, built from 2006-01-01 to 2011-05-31. The buy decision is not “which generation” — there is only 1 generation. It is which engine: 1083 cm³ / 68 hp versus 1297 cm³ / 83 hp.

There is no restyling generation in the data. Searches for Chery QQ6 S21 1.3 MT 2008, 1.1 MT 2008, or 2009 all point at the same production window. Year of a used car does not split the table into extra versions.

Which version to choose: the arithmetic

1.3 MT is the stronger car. 1.1 MT is the lighter, slightly cheaper-to-run car on highway and mixed figures.

What the larger engine buys, in numbers from the data:

Power per litre: 1.1 MT is 68 / 1.083 ≈ 62.8 hp per litre; 1.3 MT is 83 / 1.297 ≈ 64.0 hp per litre. Specific output is almost the same. The 1.3 is not a high-strung tune of the 1.1; it is a larger engine with similar specific power.

Kilograms per horsepower: 1.1 MT 990 / 68 ≈ 14.6 kg/hp; 1.3 MT 1050 / 83 ≈ 12.7 kg/hp. The 1.3 carries 60 kg more, but each horsepower has less mass to move. That matches the 2.5 s gap to 100 km/h.

Payload (gross minus kerb): 1365 − 990 = 375 kg on 1.1 MT; 1425 − 1050 = 375 kg on 1.3 MT. Load capacity does not change with the engine. You do not buy the 1.3 to haul more.

City fuel is 8 on both. Mixed is 7.2 versus 7.3. Highway is where 1.1 MT is leaner: 6.1 against 6.5. Over a 45-litre tank, mixed range is about 45 / 7.2 ≈ 6.25 tankfuls of mixed distance units on the 1.1 versus 45 / 7.3 ≈ 6.16 on the 1.3 — the tank is the same size, the mixed gap is 0.1.

Compression: 9.5 on 1.1 MT, 10 on 1.3 MT. Bore × stroke: 72 × 66.5 versus 73 × 77.5. Both take fuel 92. Both: No boost, Distributed injection (multi-point), 4 valves per cylinder.

Buy 1.3 MT if 0–100 of 14.5 s and 164 km/h top speed matter more than 60 kg and 0.4 highway consumption. Buy 1.1 MT if you want 990 kg kerb weight, 130 km/h top speed is enough, and you want the lower highway figure. There is no Automatic, no AWD, no third engine in this generation.

Prices are not in the data — not measured. “What extra money buys” here means what extra displacement buys: 15 hp, 24 Nm, 2.5 s to 100, 34 km/h of top speed, for 60 kg and a 0.1 mixed / 0.4 highway penalty, with city consumption unchanged.

Generations: only one, so generation does not pick the car

1 generation (2006-01-01 – 2011-05-31): Liftback, 2 versions — 1.1 MT and 1.3 MT. Both versions share the same start and stop dates. A 2008 1.3 MT and a 2009 1.1 MT are the same generation, not a facelift split.

Nothing in the data changes between early and late years of this window: no second body, no extra gearbox, no restyle row. Comparing generations is not available; comparing 1.1 MT and 1.3 MT is the whole catalogue.

Engines and specs (Chery QQ6 S21 engine)

Both peak power at 6000 rpm. Torque band: 1.1 MT 3500 – 4000 rpm; 1.3 MT 3800 – 4500 rpm — the 1.3’s peak torque is later. If you want punch lower in the rev range, the 1.1’s 90 Nm is quoted from 3500; the 1.3’s 114 Nm starts its quoted band at 3800.

kW: 50 versus 61, same +11 kW as the hp gap implies at the same 6000 rpm.

Performance and economy (specs, mpg)

1.1 MT: 0–100 in 17 s, top speed 130, city 8, highway 6.1, mixed 7.2. CO2: not measured. Eco class: not measured.

1.3 MT: 0–100 in 14.5 s, top speed 164, city 8, highway 6.5, mixed 7.3. CO2: not measured. Eco class: not measured.

Relative performance: 14.5 / 17 ≈ 0.85, so the 1.3’s 0–100 time is about 15% shorter. Top speed 164 / 130 ≈ 1.26, about 26% higher. Mixed economy 7.3 / 7.2 ≈ 1.014, about 1.4% more fuel on mixed. The performance step is large; the mixed-economy step is small.

City consumption equal at 8 means the 1.3 does not cost extra in the figure that usually hurts small cars most. The measured penalty is highway (+0.4) and mixed (+0.1).

Units of consumption in the source are as given (8 / 6.1 / 7.2 and 8 / 6.5 / 7.3); they are not converted here.

Dimensions and weight

Wheel sizes: not measured on both versions.

Ground clearance: 150 on 1.1 MT and 1.3 MT. Tank: 45 on both.

Kerb / gross: 990 / 1365 (1.1 MT); 1050 / 1425 (1.3 MT). The 60 kg on kerb is the same 60 kg on gross; the structure’s load allowance stays 375 kg.

Suspension is the same: Independent, spring front; Dependent, spring rear. Brakes: Disc front, Drum rear on both (English labels from the data). Chassis choice does not separate the two versions.

Reliability and problems — what the table does and does not say

The data have no failure rates, no review scores, no service intervals. Reliability and owner problems are not measured here. Do not read silence as “no problems.”

What you can compare without leaving the numbers: both engines are Gasoline, No boost, Distributed injection (multi-point), fuel 92, Manual 5, FWD. There is no turbo to choose or avoid. There is no automatic to choose or avoid. Layout is Front, transverse on both.

If a listing is labelled Chery QQ6 S21 1.3 MT, it is the 83 hp / 114 Nm / 1297 cm³ / 14.5 s / 164 km/h / 1050 kg car. If it is 1.1 MT, it is 68 hp / 90 Nm / 1083 cm³ / 17 s / 130 km/h / 990 kg. Same names must not be mixed: there are not two different 1.3 MT power figures in this generation.

Direct answer

With one generation (2006-01-01 to 2011-05-31) and two Liftback versions, pick 1.3 MT when you want 83 hp, 114 Nm, 14.5 s to 100, and 164 km/h, and accept 1050 kg and highway 6.5 / mixed 7.3. Pick 1.1 MT when you want 990 kg, highway 6.1 / mixed 7.2, and accept 68 hp, 17 s, and 130 km/h. City 8, tank 45, clearance 150, payload 375 kg, Manual 5, FWD, Gasoline, No boost — identical. Price: not measured. CO2: not measured. Wheels: not measured. Eco class: not measured.
