Though no official numbers have been released, despite those efforts, the 2019 Altima won’t actually be much lighter than its predecessor. “I don’t think it [the weight loss] is significant at the end of the day,” Reed admits. Part of that is because the new car is wider on a longer wheelbase. But it’s also because Nissan added so many more features, like more safety technology. “You want to add a bunch of stuff, but you can’t make the car heavier because that hurts fuel economy,” Reed says. Still, keeping weight in check while adding size and features is still a net win.
