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 86 saloons, the 420d Convertible ranks (top 6 in segment) in fuel consumption. Caralogy simulates its real-world cost: motorway simulation, consumption simulation and performance simulation.
Tailored to this vehicle?
Good compromise for regular use without available charging infrastructure. 6th of 86 in Combined consumption (4.5 L/100), 3rd of 73 in Tank range (1311 km).
Some metrics lag behind the segment. Check the rankings above to identify weak points.
If the priority is Combined consumption, the BMW 420d (1st with 4.2 L/100) takes the lead. If the priority is Tank range, the BMW 420d (1st with 1405 km) takes the lead.
Fuel consumption: 4.5 L/100 L/100 (6th of 86 in Combined consumption)
The 420d Convertible consumes 4.5 L/100 on the WLTP combined cycle. The segment reference is the BMW 420d (4.2 L/100).
Tank range: 1311 km (3rd of 73 in Tank range)
On a full tank, the 420d Convertible covers 1311 km on the combined cycle. The segment reference reaches 1405 km.

BMW 420d 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 420d Convertible rank in its segment?
Among the 86 saloons 2019–2023, the 420d Convertible ranks 6th of 86 in Combined consumption (4.5 L/100, behind the BMW 420d), 3rd of 73 in Tank range (1311 km, behind the BMW 420d), 72th of 86 in 0–100 km/h (7.6 s, behind the BMW M3 Competition xDrive).
What is the range of the 420d Convertible?
1311 km on a full tank (4.5 L/100 on the combined cycle) - 3rd of 73 in Tank range.
How much does the 420d 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 420d instead?
The BMW 420d leads in Combined consumption (4.2 L/100 vs 4.5 L/100). The choice depends on your priorities: check the 420d Convertible vs BMW 420d 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.
