Let's be clear: This is still a four-door sedan, so in reality, most consumers don't need to be zooming off the line. They're probably driving in a kid-friendly neighborhood anyways. However, because it is affordable and now looks really sporty, there will be plenty of men, and certainly some high school kids, driving this car. And what do all guys and high school kids have? Lead feet. We tested both the four-cylinder and six-cylinder versions of the new Altima, and there was a pretty noticeable difference from the added 88 horsepower (270 in the V6 compared to 182 in the four-cylinder) you get from the 3.5-liter engine. We could actually pass a car on a country road without cheering for the engine to get up and go. Keep in mind, we're talking foot-on-the-ground responsiveness. The four-cylinder Altima still gets up to 60 mph in 7.1 seconds, which compared to its segment, is the fastest available.
