I just did a side-by-side comparison with EPA's fuel economy website, they call the annual difference between the two, based on 15,000 miles per year driven, 55% of the time in stop-and-go traffic 45% highway, $150 per year.
One can customize the tool for more or less miles, more or less percentage stop-and-go traffic. For me, where I drive more like 10,000 miles per year, 30% stop-and-go traffic, 70% highway, it's a dead-heat, no particular difference in fuel cost between the two models.
It looks to me like they expect about $13/month difference in fuel costs between the two with their default settings on their mileage and traffic.
