BYD M6: Which Version Should You Buy?

The BYD M6 range covered one generation of Minivan production from 2010 to 2015 and offered four Gasoline versions: 2.0 MT, 2.0 AT, 2.4 MT, and 2.4 AT. All use FWD, an Inline 4-cylinder engine without boost, and a 65-litre fuel tank.

The BYD M6 range covered one generation of Minivan production from 2010 to 2015 and offered four Gasoline versions: 2.0 MT, 2.0 AT, 2.4 MT, and 2.4 AT. All use FWD, an Inline 4-cylinder engine without boost, and a 65-litre fuel tank. The central choice is between the 1991 cc engine with 140 hp and 186 Nm and the 2378 cc engine with 165 hp and 220 Nm, followed by the decision between a 5-speed Manual and a 4-speed Automatic. Based strictly on the measured figures, 2.0 MT is the economy-focused choice, while 2.4 MT provides the strongest measured performance. The Automatic versions may suit buyers who prioritize transmission type, but their acceleration, maximum-speed, consumption, and kerb-weight figures are not measured.

BYD M6 generations and versions

The BYD M6 has one generation in this catalogue. The 1 generation was produced from 2010 to 2015 as a Minivan, with four versions: 2.0 MT, 2.0 AT, 2.4 MT, and 2.4 AT. There is therefore no between-generation mechanical change to compare. Choosing an M6 means comparing engines and gearboxes within the same generation rather than deciding between different generations.

The engine determines output and injection type. Both 2.0 versions produce 140 hp at 6000 rpm and 186 Nm at 4000 rpm from 1991 cc, using Distributed injection (multi-point). Both 2.4 versions produce 165 hp at 5000 rpm and 220 Nm from 2378 cc, using Direct injection (direct); the engine speed for peak torque is not measured.

Moving from either 2.0 version to its 2.4 counterpart adds 387 cc, 25 hp, and 34 Nm. That represents approximately 12.4% more horsepower and 18.3% more torque. Output per litre is approximately 70.3 hp for the 1991 cc engine and 69.4 hp for the 2378 cc engine, so their specific horsepower is very close even though the larger engine supplies more total output.

BYD M6 engine and specs

Each version has 4 valves per cylinder and uses 92 fuel. The 2.0 MT and 2.0 AT have Distributed injection (multi-point), whereas the 2.4 MT and 2.4 AT have Direct injection (direct). Engine location, compression ratio, and bore-and-stroke measurements are not measured for any version.

For buyers comparing horsepower and torque, the gearbox does not alter the stated engine output: 2.0 MT and 2.0 AT both have 140 hp and 186 Nm, while 2.4 MT and 2.4 AT both have 165 hp and 220 Nm. The transmission choice is therefore between a 5-speed Manual and a 4-speed Automatic, not between different power ratings.

BYD M6 performance, acceleration, and fuel economy

Among versions with measured results, 2.4 MT reaches 100 km/h 3 seconds sooner than 2.0 MT and has a top speed 5 km/h higher. Its extra 25 hp and 34 Nm therefore accompany the strongest documented performance in the range.

That performance comes with higher measured fuel use. Compared with 2.0 MT, 2.4 MT consumes an additional 2.5 L/100 km in the city, 1.1 L/100 km on the highway, and 1.7 L/100 km combined. In relative terms, its combined figure is approximately 19.1% higher. Buyers prioritizing the lowest documented consumption should therefore favor 2.0 MT; buyers prioritizing acceleration should favor 2.4 MT.

No equivalent performance or economy figures were measured for 2.0 AT or 2.4 AT. Their results should not be inferred from the Manual versions merely because they share the same engines.

BYD M6 dimensions, weight, clearance, and tank size

Overall exterior dimensions, width, boot dimensions, and wheel sizes are not measured for 2.0 MT, 2.0 AT, 2.4 MT, or 2.4 AT. Every version has 179 mm of ground clearance and a 65-litre fuel tank.

The measured 2.4 MT is 50 kg heavier than 2.0 MT, while the gross weight of each 2.4 version is 50 kg above that of the corresponding 2.0 version. Despite that increase, the larger Manual has a better measured weight-to-power ratio: 2.0 MT carries approximately 12.2 kg per horsepower, compared with approximately 10.7 kg per horsepower for 2.4 MT. The additional 25 hp more than offsets the additional 50 kg in this comparison.

All four versions share an Independent, spring front suspension and a Semi-independent, torsion rear suspension. They also have Disc front brakes and Disc rear brakes.

Which BYD M6 version should you choose?

Choose 2.0 MT if documented fuel economy matters most. It is the only version combining the lower-output 140 hp engine with complete measured consumption data, including 8.9 L/100 km combined. Its 1710 kg kerb weight is also 50 kg below that of 2.4 MT. The trade-off is an 18-second 0–100 km/h time and a 180 km/h top speed.

Choose 2.4 MT if measured performance matters most. Its 165 hp and 220 Nm exceed 2.0 MT by 25 hp and 34 Nm, and it reaches 100 km/h 3 seconds sooner. It also improves the weight-to-power ratio by approximately 1.5 kg per horsepower. The trade-off is greater consumption in every measured cycle, including 10.6 L/100 km combined rather than 8.9 L/100 km.

Choose 2.0 AT if the required combination is the 1991 cc, 140 hp engine and a 4-speed Automatic. It matches 2.0 MT for stated engine output, torque, FWD layout, 179 mm clearance, 65-litre tank, and 2235 kg gross weight. However, its acceleration, top speed, fuel consumption, and kerb weight are not measured, so it cannot be ranked against 2.0 MT on those criteria.

Choose 2.4 AT if a 4-speed Automatic and the range’s higher-output engine are both priorities. It provides the same stated 165 hp and 220 Nm as 2.4 MT, along with FWD, 179 mm clearance, a 65-litre tank, and a 2285 kg gross weight. Its acceleration, top speed, fuel consumption, and kerb weight are not measured, preventing a numerical performance or economy comparison with 2.4 MT.

On the available measurements, the decision is clearest between the Manual versions: 2.0 MT offers the lower documented running consumption, while 2.4 MT offers the better documented acceleration and weight-to-power ratio. The Automatic versions remain transmission-led choices because the catalogue does not provide enough measured data to claim that either is faster, slower, more economical, or heavier than its Manual counterpart.
