Isn't the 2013 Altima a redesign though? At least in a lot of aspects. I know the EPA rating went up for the '13s over its predecessors.
It's still not a more efficient car. Efficient cars don't sound like tractors. Thus why the 98 Mustangs were so fuel inefficient.
Your point addresses the range, not the mileage. As for reasons for not getting the gasoline Titanium, the major road that my wife and I need to access to get to the interstate has a speed limit of 55mph, and it's at least 10 miles to the interstate. That's perfect for a hybrid. That being said, I'd say 70 percent of her driving will be on local roads or the road I mentioned. Hybrid for the win.
Mileage = Range. They're one in the same. Miles per gallon is literally what range you can get on each gallon of gas multipled by the number of gallons your tank can hold. Simple arithmetic - the larger the tank, the greater the mileage. The greater the mileage, the wider/longer the range before you need to fill up. You're arguing semantics here.
Bottom line: Altima rules MPG on long stretches because it has more gas to do so. That does not make it more efficient.
By that logic, a kid who brings 4 different types of calculators and an iPad to math class is more mathematically inclined because they can punch up the answer faster than other kids who use pen and paper, or who only have a basic calculator. Negative.
As for your trip you're confusing me now. Previously you said "...people are getting about 36-37mpg at a highway speed of 75, which, is actually less than the Altima." Now, you're saying that just because it takes a bit to get to the highway (I'm assuming the highway has a decent speed speed limit) and just because of the local road driving, that the hybrid would be more logical. So either you don't spend a lot of time on the highway/freeway, or something isn't adding up. If you don't spend a lot of time on the freeway then what's it matter that the Altima does better "...at a highway speed of 75"?
If I spend 80% of my time going less than 60, a hybrid makes sense and an Altima is moot; shouldn't even be in the discussion and the mileage of the Fusion Hybrid should be forefront.
