Guys, you have to remember he stated NYC driving. I've never been there, but I imagine you spend more time idling than moving which obviously would KILL gas mileage. Also, he never stated how many gallons were used in these 120 miles.
I get 19-20mpg in my city driving, but traffic generally moves well with good distance between stop lights. That's around 260-280 per tank when I fill her with around 14 gallons.
I get 25-28mpg depending on season and weather. Mostly all highway and I do not stomp on it.
I get the same on the highway. These cars are really great cruising in 5th gear. i regularly get 25-27MPG on 87 octane with all highway driving. I drive 50 miles a day on the highway. My start and destination are within 1/2 mile from the on/off ramps...so i truely do nearly 100% highway driving.
