Among the 36 limousines, the 840d xDrive Convertible ranks (mid-table) in acceleration. Caralogy simulates its real-world performance: motorway simulation, performance simulation and consumption simulation.
Tailored to this vehicle?
Demanding drivers: 9th of 36 in Top speed (250 km/h). 9th of 36 in Top speed (250 km/h).
Regular family use with bulky luggage. The space and boot are sport-calibrated, not utility. A sedan or SUV from the same manufacturer would be more practical daily.
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: 5.1 s 0-100 (24th of 36 in 0–100 km/h)
In pure acceleration, the 840d xDrive Convertible ranks 24th of 36 in 0–100 km/h, 2.1 s off the reference Porsche Panamera Turbo S (3.0 s).
Top speed: 250 km/h (9th of 36 in Top speed)
Top speed of 250 km/h. The segment reference reaches 315 km/h.

BMW 840d 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 840d xDrive Convertible rank in its segment?
Among the 36 limousines 2019–2023, the 840d xDrive Convertible ranks 24th of 36 in 0–100 km/h (5.1 s, behind the Porsche Panamera Turbo S), 9th of 36 in Top speed (250 km/h, behind the Porsche Panamera Turbo S), 36th of 36 in Power-to-weight (167 hp/t, behind the BMW M8 Competition Coupe).
How much does the 840d 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 5.1 s). The choice depends on your priorities: check the 840d 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.
