Caralogy Analysis · tailored to this vehicle
Caralogy Verdict
Suitable for
Optimised urban and peri-urban trips with no charging to manage. 1st of 11 in Top speed (250 km/h).
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 Power-to-weight, the Bmw 760i xDrive (1st with 240 hp/t) takes the lead.
Acceleration: 5.1 s 0-100 (8th of 11 in 0–100 km/h)
