BMW i7 xDrive60 First Drive Review 2023

Under the floor of the new i7 resides a 101.7-kilowatt-hour lithium-ion battery pack rated by the EPA for 310 miles of range, which puts it roughly midpack in its class. 

That battery is fed by a 400-volt underlying architecture, although BMW has taken pains to ensure the system still recharges rapidly, at up to 195 kilowatts using a DC charger. 

That allows the i7 to go from 10 to 80 percent state of charge in 34 minutes – impressive, but again, no record-setter. 

Just as with the motor, however, battery performance is more than what shows on paper.  

The i7 features predictive thermal management that helps preserve the overall life of the battery pack.

when the i7’s nav system is set to a nearby fast charger, it automatically heats or cools the battery for the most efficient charging. 

The i7 achieves this overall efficiency despite its 5,917-pound curb weight by putting a heavy focus on aerodynamics.
