BAIC X55

The BAIC X55 has one generation and two versions that share the same catalogue name. This piece is a version-to-version buyer's comparison, using only the supplied figures.

The BAIC X55 is a 5-door SUV with one generation on record (from 2022-01-01, no end date) and two current versions, both named 1.5 DCT. They are not the same car. One is 1.5 DCT with 188 hp; the other is 1.5 DCT with 177 hp. Same displacement (1498), same torque (305 Nm), same 7-speed Robotic gearbox, same FWD, same 7.8 s to 100 km/h.

# BAIC X55: which version to buy

The BAIC X55 is a 5-door SUV with one generation on record (from 2022-01-01, no end date) and two current versions, both named 1.5 DCT. They are not the same car. One is 1.5 DCT with 188 hp; the other is 1.5 DCT with 177 hp. Same displacement (1498), same torque (305 Nm), same 7-speed Robotic gearbox, same FWD, same 7.8 s to 100 km/h. The 188 hp car is 75 kg lighter at the kerb, uses 0.6 fewer litres per 100 km on the mixed cycle, and is the only one with a measured top speed (200 km/h). The 177 hp car is the only one with a measured CO2 figure (181). If you are choosing a BAIC X55, the decision is between these two 1.5 DCT rows, not between generations.

There is no second generation in this dataset. Searches for “BAIC X55 II” do not map to a listed generation here. There is also no separate “Plus”, “Verve”, or “Beijing” engine line in the data: both rows are Gasoline, Inline 4, Front, transverse, Direct injection (direct), Euro 6, fuel 92.

Generations: what actually changed

1 generation (start 2022-01-01, stop not measured) is the whole catalogue: body SUV 5-doors, 2 versions, both still open-ended. There is no restyling row and no later generation to compare year-on-year. “What generation changed” is therefore a null: nothing replaced 1 generation. All differences sit inside that one generation, between the two 1.5 DCT tunes.

BAIC X55 engine specs: the two 1.5 DCT rows

Both versions use a 1498 Gasoline engine, 4 cylinders, Inline, 4 valves per cylinder, Front, transverse, Direct injection (direct). Boost is not measured on both. Peak torque is 305 Nm at 4250 rpm on both. Peak power is at 5500 rpm on both. Gearbox is Robotic, 7 speeds, drive FWD.

Power gap: 188 − 177 = 11 hp (138 − 130 = 8 kW). Specific output on 1498 cc (1.498 L): 188 / 1.498 ≈ 125.5 hp/L versus 177 / 1.498 ≈ 118.2 hp/L. Difference: about 7.3 hp per litre in favour of 1.5 DCT 188 hp. Torque per litre is identical: 305 / 1.498 ≈ 203.6 Nm/L.

Engine type, size in cc, and layout are the same string in both rows. There is no Mercedes engine label in the data. Engine oil grade is not measured. Compression ratio and bore × stroke are not measured.

Performance and economy: same sprint, different thirst

1.5 DCT 188 hp: 0–100 7.8 s, top speed 200 km/h, mixed consumption 7.2, city not measured, highway not measured, CO2 not measured.

1.5 DCT 177 hp: 0–100 7.8 s, top speed not measured, mixed consumption 7.8, city not measured, highway not measured, CO2 181.

The 0–100 figure does not separate them. The 188 hp car is not quicker to 100 in this table; it is 11 hp stronger and 75 kg lighter, yet the recorded sprint is the same 7.8 s. What does separate them is mixed fuel use: 7.8 − 7.2 = 0.6 L/100 km. On a 53 L tank (both), mixed range from the given figures is 53 / 7.2 × 100 ≈ 736 km for 1.5 DCT 188 hp versus 53 / 7.8 × 100 ≈ 679 km for 1.5 DCT 177 hp — about 57 km more per tank on the lighter, thirstier-labelled 188 hp row. City and highway mpg are not measured on either, so a “real urban” ranking cannot be made from this file.

Top speed is only measured on 1.5 DCT 188 hp (200 km/h). Treating the 177 hp car as slower on a highway is not supported: the value is not measured, not “lower”.

Dimensions, weight, tank: the 75 kg gap

Length, overall size, ground clearance, and wheel sizes are not measured on both versions. Do not fill those from memory.

Kerb and gross:

Gross mass is the same 1970. The 177 hp 1.5 DCT is 75 kg heavier at the kerb, so payload is 420 − 345 = 75 kg lower. Mass-to-power: 1550 / 188 ≈ 8.24 kg/hp versus 1625 / 177 ≈ 9.18 kg/hp. The 188 hp car carries about 0.94 kg less per horsepower.

Front suspension Independent, spring; rear Semi-independent, springorts hélicoïdaux, sem (English label as given); front brakes Ventilated disc; rear Disc — identical on both, so chassis wording does not pick a winner.

Which version to choose

There is no generation fork. Choose inside 1 generation between two 1.5 DCT names.

Take 1.5 DCT (188 hp) if you want the higher specific output (≈125.5 hp/L), the lower kerb (1550), the higher payload (420), the lower mixed figure (7.2), the longer mixed tank range from those figures (≈736 km), and the only listed top speed (200 km/h). Power, weight, and mixed consumption all point the same way. The 0–100 time does not: it is still 7.8 s.

Take 1.5 DCT (177 hp) if you need the one row that publishes CO2 (181). That is the only measured environmental number in the pair. You give up 11 hp, 8 kW, 75 kg of payload, and 0.6 L/100 km on the mixed cycle, and you accept top speed not measured. Torque stays 305 Nm, gearbox stays Robotic 7, drive stays FWD, tank stays 53, fuel stays 92, eco class stays Euro 6.

What “extra” does not buy here: a different body, a second generation, AWD, a larger engine, or a different gearbox type. Those are not in the data. Interior, oil spec, list price, Sri Lanka or Egypt pricing, and “for sale” stock are not measured. Reliability and known problems are not measured.

Short ranking on the numbers we have. On power, kerb, payload, mixed consumption, and mass-to-power, 1.5 DCT 188 hp is the stronger catalogue row. On documented CO2, only 1.5 DCT 177 hp has a figure. If both sit in front of you with the same name on the badge, read the horsepower line: 188 versus 177 is the identifier that keeps the two 1.5 DCT pages from collapsing into one.
