BMW X7

Which BMW X7 Version Should You Buy?

The BMW X7 choice depends chiefly on whether you prioritize fuel consumption, acceleration, or power. Among the recorded versions, the first-generation 40d 3.0 AT xDrive Steptronic has the lowest combined consumption at 6.6, while the restyled M60i 4.4 AT MHEV xDrive Steptronic and first-generation M50i 4.4 AT xDrive Steptronic share the quickest 0–100 km/h time of 4.7 seconds.

Every listed X7 is an SUV 5-doors with AWD, an 8-speed Automatic gearbox, independent pneumatic suspension at both ends, and 221 mm of ground clearance. Price and sale data are not measured, so this comparison cannot determine whether any version justifies a specific financial premium.

BMW X7 generations and the changes that matter

The BMW X7 has one generation presented in two phases within the supplied data, although the catalogue records two generation entries. The original first generation ran from October 2018 through March 2022 as an SUV 5-doors and includes seven recorded versions. Its engine range spans 265–530 hp, while combined consumption, where measured, spans 6.6–11.1.

The first-generation restyling began in April 2022 and has no recorded end date. It remains an SUV 5-doors and contains three versions: 40i 3.0 AT MHEV xDrive Steptronic, 40d 3.0 AT MHEV xDrive Steptronic, and M60i 4.4 AT MHEV xDrive Steptronic. Compared with the original phase, all three restyled names add MHEV. The range still peaks at 530 hp, but the recorded maximum torque rises from 775 Nm in the original M50d 3.0 AT xDrive Steptronic to 750 Nm in the restyled range; therefore, the earlier M50d retains a 25 Nm advantage over the restyled torque leader.

BMW X7 engine options and specs

Power per litre separates several apparently similar choices. The original M50d 3.0 AT xDrive Steptronic produces about 133.6 hp per litre, the highest result in the catalogue. The restyled 40i 3.0 AT MHEV xDrive Steptronic follows at about 126.8 hp per litre. Both 530 hp V-shaped engines produce about 120.6 hp per litre, while the original 30d 3.0 AT xDrive Steptronic records about 88.5 hp per litre.

The two original versions named 40i 3.0 AT xDrive Steptronic must be distinguished by output. The 340 hp version has 458 Nm, reaches 100 km/h in 6.1 seconds, and has measured combined consumption of 9.5. The later 333 hp version has 450 Nm, takes 6.3 seconds, and records 8.4 combined. It gives up 7 hp, 8 Nm, and 0.2 seconds, but uses 1.1 less on the combined measure.

BMW X7 performance and fuel economy

For maximum measured economy, the original 40d 3.0 AT xDrive Steptronic is the clear choice: its combined figure of 6.6 is 0.7 lower than the 30d and 0.9 lower than the M50d. It also reaches 100 km/h in 6.1 seconds, 0.9 seconds sooner than the 30d.

The M50d 3.0 AT xDrive Steptronic is the strongest performance-and-economy compromise in the original range. It matches the 50i’s 5.4-second acceleration and 250 km/h top speed, yet its measured combined consumption is 7.5; the corresponding 50i figure is not measured. The M50d also supplies 125 Nm more torque than the 50i.

For outright acceleration, choose either the original M50i 4.4 AT xDrive Steptronic or the restyled M60i 4.4 AT MHEV xDrive Steptronic. Both make 530 hp and 750 Nm, reach 100 km/h in 4.7 seconds, and top out at 250 km/h. The recorded combined figures are 11.1 for the M50i and 13.3 for the M60i, a difference of 2.2 in favor of the earlier version.

BMW X7 dimensions, weight, tank and wheel specs

Exterior length and other body dimensions are not measured in the supplied data. Every version has 221 mm of ground clearance and an 83-litre tank.

The restyled 40i 3.0 AT MHEV xDrive Steptronic has the lowest kerb weight at 2,320 kg. It is 40 kg lighter and 47 hp more powerful than the later 333 hp original 40i, improving the calculated weight-to-power figure from 7.09 to 6.11 kg/hp. The original M50i has the best weight-to-power result at 4.82 kg/hp; the restyled M60i matches its output but weighs 120 kg more, raising the figure to 5.05 kg/hp.

Which BMW X7 version to buy and why

For the lowest measured combined consumption, buy the original 40d 3.0 AT xDrive Steptronic. Its 6.6 result is the catalogue minimum, and its 340 hp output still delivers a 6.1-second 0–100 km/h time.

For a diesel with substantially more torque, the restyled 40d 3.0 AT MHEV xDrive Steptronic offers 700 Nm, which is 242 Nm more than the original 40d’s recorded 458 Nm. Acceleration and top speed remain identical at 6.1 seconds and 243 km/h, while combined consumption increases from 6.6 to 8.7.

For the most compelling balance of acceleration, torque, and measured consumption, choose the original M50d 3.0 AT xDrive Steptronic. Its 400 hp and catalogue-leading 775 Nm produce a 5.4-second sprint, while combined consumption is 7.5. It is 1.3 seconds quicker than the 30d for an increase of only 0.2 in combined consumption.

For Gasoline performance without choosing a V-shaped engine, the restyled 40i 3.0 AT MHEV xDrive Steptronic is the strongest option. It has 380 hp and reaches 100 km/h in 5.8 seconds—40 hp more and 0.3 seconds quicker than the original 340 hp 40i. Its combined consumption is 10.5, which is 1.0 higher than that earlier version.

For the best power-to-weight result, buy the original M50i 4.4 AT xDrive Steptronic. It matches the restyled M60i’s 530 hp, 750 Nm, 4.7-second acceleration, and 250 km/h top speed, but is 120 kg lighter and records combined consumption 2.2 lower. Without price, maintenance, or reliability measurements, the supplied specifications provide no numerical reason to prefer the M60i unless the restyled phase and its MHEV designation are priorities in themselves.

Prices, used-car availability, engine-oil requirements, coolant specifications, service needs, problems, and reliability are not measured. Those factors should therefore be checked separately before purchase; the supplied data supports a specifications comparison, not a complete ownership-cost judgment.
