Yes like the above said only if you're cruising and not in stop and go traffic. Stopping and acceleration that extra 50 pounds from a V8 does add up in poor fuel consumption not to mention the higher burn rate at idle unless you have cylinder deactivation or turning off the car at stop lights
That's why I said in another post if someone is getting a XC90 as a weekend only car and they drive only highways from Tung Chung into Kowloon/island AND they time their departure early in the morning to avoid getting stuck once they get into the city core, it's probably all right if they get the gas guzzler versus a Honda minivan
