Frequently asked questions
BMW 840i: what you need to know
Well-argued answers to the most asked questions about this model, based on Caralogy data and simulations.
Running costs depend on your profile (mileage, charging type, city/highway mix). Use the Caralogy consumption simulator for a personalised estimate.
The Porsche Panamera Turbo S Sport Turismo leads in 0–100 km/h (3.0 s vs 5.0 s). The choice depends on your priorities: check the 840i vs Porsche Panamera Turbo S Sport Turismo duel for a detailed comparison.
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.
