Caralogy Analysis · tailored to this vehicle
Caralogy Verdict
Suitable for
Demanding drivers: 3rd of 31 in Top speed (250 km/h). 3rd of 31 in Top speed (250 km/h).
Less suitable for
Frequent urban trips with stop-and-go. At 7,7 L/100 km on the combined cycle, consumption rises in the city without electric assistance. An HEV or PHEV would be more economical for this use profile.
Alternatives to consider
If the priority is 0–100 km/h, the Bmw M5 Competition (1st with 3.3 s) takes the lead. If the priority is Top speed, the Bmw 540i xDrive (1st with 250 km/h) takes the lead.
Acceleration: 5.4 s 0-100 (30th of 31 in 0–100 km/h)
In pure acceleration, the 640i Gran Turismo ranks 30th of 31 in 0–100 km/h, 2.1 s off the reference Bmw M5 Competition (3.3 s).
Top speed: 250 km/h (3rd of 31 in Top speed)
Top speed of 250 km/h. The segment reference reaches 250 km/h.
