BMW 840i 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 840i Convertible rank in its segment?
Among the 36 limousines 2019–2023, the 840i Convertible ranks 36th of 36 in 0–100 km/h (5.5 s, behind the Porsche Panamera Turbo S), 19th of 36 in Top speed (250 km/h, behind the Porsche Panamera Turbo S), 28th of 36 in Power-to-weight (181 hp/t, behind the BMW M8 Competition Coupe).
How much does the 840i 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 5.5 s). The choice depends on your priorities: check the 840i 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.
