Caralogy Methodology
Performance (0-100, top speed) simulated by the Caralogy physics engine (SCx, Crr, real torque curves). Motorway consumption values estimated from the manufacturer WLTP cycle.
See full methodologyManufacturer data · WLTP-estimated consumption · Caralogy-simulated performance
Among the 10 limousines hybrid, the 840d xDrive Convertible ranks (in the bottom third) in acceleration. Caralogy simulates its real-world performance: motorway simulation, performance simulation and consumption simulation.
Tailored to this vehicle?
Optimised urban and peri-urban trips with no charging to manage.
Home charging access not leveraged. If you have a dedicated outlet, a PHEV would allow daily commutes in pure electric mode.
If the priority is 0–100 km/h, the BMW 760i xDrive (1st with 4.2 s) takes the lead. If the priority is Top speed, the BMW 740d xDrive (1st with 250 km/h) takes the lead.
Acceleration: 5.1 s 0-100 (8th of 10 in 0–100 km/h)
In pure acceleration, the 840d xDrive Convertible ranks 8th of 10 in 0–100 km/h, 0.9 s off the reference BMW 760i xDrive (4.2 s).
Top speed: 250 km/h (5th of 10 in Top speed)
Top speed of 250 km/h. The segment reference reaches 250 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 10 limousines hybrid 2018–2022, the 840d xDrive Convertible ranks 8th of 10 in 0–100 km/h (5.1 s, behind the BMW 760i xDrive), 5th of 10 in Top speed (250 km/h, behind the BMW 740d xDrive), 9th of 10 in Power-to-weight (167 hp/t, behind the BMW 760i xDrive).
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 BMW 760i xDrive instead?
The BMW 760i xDrive leads in 0–100 km/h (4.2 s vs 5.1 s). The choice depends on your priorities: check the 840d xDrive Convertible vs BMW 760i xDrive 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.
