BYD G3: which version to buy (1 generation, 2009–2014)

The BYD G3 exists as 1 generation only (2009-01-01 to 2014-12-31), Sedan, 6 versions, all Gasoline, 4 Inline cylinders, No boost, Front, transverse, FWD, 92 fuel. There is no second generation in this catalogue, so a “newer G3” is not a choice here. The real choice is among two 1.5 MT rows at 105 hp, two 1.8 MT rows at 121 hp, and two 1.8 CVT rows at 121 hp.

Same names must be kept exactly as in the database; they are told apart by displacement, kerb weight, tank, brakes, and which figures are measured.

BYD G3 specs by version: what the extra 16 hp buys

121 − 105 = 16 hp (about 15% more peak power). Peak torque is 160 Nm versus 145 Nm (+15 Nm). The 1.5 engines are 1468 cm³; the 1.8 rows are listed as 1838, 1839, or 1800 cm³. Specific output:

The smaller 1.5 MT is the denser engine on paper. The 1.8 versions win on absolute power and on weight per horsepower (next section), not on hp per litre.

Weight per horsepower and payload (dimensions that actually differ)

Gross mass is 1582 kg on every version. Ground clearance is 170 mm on every version. Wheel sizes are not measured on every version. Kerb mass is the lever.

The lightest listed 1.5 MT (1170 kg) still carries 11.14 kg per hp. Both fully measured 121 hp cars at 1200 kg sit at 9.92 kg per hp1.60 kg/hp lighter than the 1210 kg 1.5 MT, and 1.22 kg/hp lighter than the 1170 kg 1.5 MT. If the question is “which engine works less hard per kilogram,” the 1.8 rows win. If the question is “which listed car can carry the most,” the 1170 kg 1.5 MT has 412 kg of payload versus 372 kg on the 1210 kg 1.5 MT (+40 kg).

BYD G3 engine: 1.5 MT versus 1.8 MT versus 1.8 CVT

All six use Distributed injection (multi-point), Manual 5 or Variable, FWD. Peak rpm: 5800 on both 1.5 MT; 6000 on all four 1.8 versions. Torque rpm: 4800 on 1.5; 3700 – 4200 on 1.8.

Buy a 1.5 MT if you want the only 0–100 figure that is 11 s, the only top speed of 170, and (on the 1210 kg row) the only mixed consumption of 6.5 L/100 km. That 1.5 MT (105 hp, 1468 cm³, Ventilated disc front, tank 50 L) is the only version with city 8.5, highway 5.4, and mixed 6.5 all measured.

The other 1.5 MT (105 hp, 1468 cm³, kerb 1170 kg) matches 11 s and 170, Manual 5, same 145 Nm, but city / highway / mixed and tank are not measured, and the front brakes are Disc, not Ventilated disc. Same name, same power: choose the 1210 kg row when you need fuel and tank numbers; choose the 1170 kg row when you need 40 kg less kerb and 40 kg more payload.

Buy a 1.8 MT if you want 121 hp and 160 Nm with Manual 5, without paying the CVT’s measured fuel penalty. Neither 1.8 MT has 0–100 or top speed measured. The 1838 cm³ 1.8 MT has tank 50 L and kerb 1200 kg; the 1800 cm³ 1.8 MT has tank not measured and kerb 1207 kg (+7 kg). Front brakes: Ventilated disc on the 1838 cm³ row, Disc on the 1800 cm³ row.

Buy a 1.8 CVT if you want Variable instead of Manual 5. Both 1.8 CVT rows: 121 hp, 160 Nm, 0–100 12 s, top speed 175. Versus the measured 1.5 MT: +1 s to 100, +5 on top speed. The 1839 cm³ 1.8 CVT is the only Variable row with fuel measured: city 10.4, highway 6.9, mixed 8.2. Versus the 1.5 MT mixed 6.5, that is +1.7 L/100 km (about 26% more). City 10.4 − 8.5 = +1.9; highway 6.9 − 5.4 = +1.5. The 1800 cm³ 1.8 CVT matches 12 s / 175 but kerb, tank, and all three consumption figures are not measured; front brakes Disc.

BYD G3 mpg / fuel: the only measured pair

Only two versions have a full consumption set:

On a 50 L tank, mixed range arithmetic is 50 ÷ 6.5 × 100 ≈ 769 km versus 50 ÷ 8.2 × 100 ≈ 610 km (about 159 km less on the CVT, mixed). Highway: 50 ÷ 5.4 × 100 ≈ 926 km versus 50 ÷ 6.9 × 100 ≈ 725 km. City: 50 ÷ 8.5 × 100 ≈ 588 km versus 50 ÷ 10.4 × 100 ≈ 481 km.

The other four versions: consumption not measured. Three of those also have tank not measured. Do not treat a blank as “this engine uses no fuel.”

BYD G3 2012 / 2013 / 2014 (and years that are not this car)

Production in the data is 2009-01-01 to 2014-12-31 for the generation and for every version. A 2012, 2013, or 2014 G3 is still 1 generation, still these six rows. There is no 2016, 2023, 2024, or 2025 G3 in this dataset, and no G318 as a separate model here. Year of first registration does not add a seventh engine.

Chassis that does not change the ranking

Front suspension Independent, spring and rear Semi-independent, torsion on all six. Rear brakes Disc on all six. Front brakes split: Ventilated disc on the 1210 kg 1.5 MT, the 1838 cm³ 1.8 MT, and the 1839 cm³ 1.8 CVT; Disc on the 1170 kg 1.5 MT, the 1800 cm³ 1.8 MT, and the 1800 cm³ 1.8 CVT. If ventilated fronts matter, pick from the first trio.

Which version to choose (short)

1. Lowest measured fuel, only 11 s 0–100, tank 50 L, Ventilated disc: 1.5 MT (105 hp, 77 kW, 1468 cm³, kerb 1210 kg). Cost in this table: 16 hp and 15 Nm less than the 1.8s, 11.52 kg/hp, 372 kg payload. 2. Lightest listed kerb and largest listed payload, same 105 hp and 11 s: 1.5 MT (105 hp, 1468 cm³, 1170 kg). Fuel, tank, and ventilated fronts: not measured / Disc. 3. Most hp with Manual 5 and measured tank 50 L: 1.8 MT (121 hp, 1838 cm³, 1200 kg). 0–100 and top speed not measured; fuel not measured. 9.92 kg/hp. 4. Same 121 hp Manual, 1800 cm³: 1.8 MT (121 hp, 1800 cm³, 1207 kg). Tank and fuel not measured; front Disc. 5. Variable gearbox with every performance and fuel cell filled: 1.8 CVT (121 hp, 1839 cm³, 1200 kg). 12 s, 175, mixed 8.2 versus 6.5 on the measured 1.5 MT. 6. Variable with 12 s and 175 but almost everything else blank: 1.8 CVT (121 hp, 1800 cm³). Kerb, tank, mpg: not measured.

There is no generation-to-generation jump: pokoleniy = 1. The extra 16 hp is the 1.8 package; the extra fuel on the only measured 1.8 CVT is +1.7 L/100 km mixed; the extra speed is +5 versus 170. If a figure is missing on the row you want, it is not measured in this catalogue.
