The big SUV is a step in fulfilling Cadillac's vision for an all-electric lineup of "tier one" luxury vehicles.

Cadillac has officially introduced the Escalade IQL, an even bigger version of its electric full-size SUV. Cadillac unveils the Escalade IQL, a stretched version of the electric Escalade IQ, measuring 228.

Recharging the Escalade IQL can come as quickly as 116 miles per 10 minutes of charge time when using a DC fast charger, or as slow as 15 miles of range per hour when using the 7.7-kW dual-level charge cord.
