Caralogy Analysis

Tailored to this vehicle?

Caralogy Verdict
Suitable for

Optimised urban and peri-urban trips with no charging to manage.

Less suitable for

Home charging access not leveraged. If you have a dedicated outlet, a PHEV would allow daily commutes in pure electric mode.

Alternatives to consider

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 760i xDrive (1st with 250 km/h) takes the lead.

Acceleration: 5.1 s 0-100 (9th of 10 in 0–100 km/h)

In pure acceleration, the 840d xDrive Convertible ranks 9th of 10 in 0–100 km/h, 0.9 s off the reference Bmw 760i xDrive (4.2 s).

Top speed: 250 km/h (9th of 10 in Top speed)

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

Frequently asked questions

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.

Among the 10 limousines hybrid 2018–2022, the 840d xDrive Convertible ranks 9th of 10 in 0–100 km/h (5.1 s, behind the Bmw 760i xDrive), 9th of 10 in Top speed (250 km/h, behind the Bmw 760i xDrive), 10th of 10 in Power-to-weight (167 hp/t, behind the Bmw 760i xDrive).

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

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.
