Caralogy Verdict
Suitable for

Demanding drivers: 16th of 48 in Power-to-weight (259 hp/t). 16th of 48 in Power-to-weight (259 hp/t).

Less suitable for

Frequent urban trips with stop-and-go. At 10,1 L/100 km on the combined cycle, consumption rises in the city without electric assistance. An HEV or PHEV would be more economical for this use profile.

Alternatives to consider

If the priority is 0–100 km/h, the Porsche Panamera Turbo S (1st with 3.0 s) takes the lead. If the priority is Top speed, the Porsche Panamera Turbo S (1st with 315 km/h) takes the lead.

Acceleration: 4.0 s 0-100 (18th of 48 in 0–100 km/h)

In pure acceleration, the M850i xDrive Convertible ranks 18th of 48 in 0–100 km/h, 1.0 s off the reference Porsche Panamera Turbo S (3.0 s).

Top speed: 250 km/h (43th of 48 in Top speed)

Top speed of 250 km/h. The segment reference reaches 315 km/h.

BMW M850i xDrive Convertible: what you need to know

Well-argued answers to the most asked questions about this model, based on Caralogy data and simulations.

Where does the M850i xDrive Convertible rank in its segment?

Among the 48 limousines 2018–2022, the M850i xDrive Convertible ranks 18th of 48 in 0–100 km/h (4.0 s, behind the Porsche Panamera Turbo S), 43th of 48 in Top speed (250 km/h, behind the Porsche Panamera Turbo S), 16th of 48 in Power-to-weight (259 hp/t, behind the BMW M8 Competition Coupe).

How much does the M850i xDrive Convertible cost to run?

Running costs depend on your profile (mileage, charging type, city/highway mix). Use the Caralogy consumption simulator for a personalised estimate.

Why not a Porsche Panamera Turbo S instead?

The Porsche Panamera Turbo S leads in 0–100 km/h (3.0 s vs 4.0 s). The choice depends on your priorities: check the M850i xDrive Convertible vs Porsche Panamera Turbo S duel for a detailed comparison.

How does Caralogy calculate its figures?

Caralogy does not reproduce manufacturer figures: we recalculate every number through physics simulation, starting from SCx, mass and the power curve. This is why our figures at 130 km/h differ from WLTP. Full methodology on the dedicated page.
