2012's Versa 1.6SV is an optional upgrade for those who want a little more horsepower. This generation's model weighs 250 pounds less than previous years. The Versa sedan uses a 1.6-liter four-speed automatic with continuously variable transmissions.
According to Consumer Reports, the "EPA ratings for the CVT version are now 30 mpg city, 38 mpg highway. This falls shy of the magic 40 mpg highway number many competitors are going for, but it's a big jump from the previous Versa, which only managed 25/33 with the four-speed automatic box."1
A couple of years ago, a (very) base Versa would run you $9990, but it didn't even include FM or AM radios. It was also manual transmission. Now, with all those, plus automatic, antilock brakes, stability control, air conditioning and destination charges, your Versa begins at $11,750.
As for the Versa 1.6SV sedan, you're still looking to spend around $15,490. This is lower than the 2009 1.8S sedan cost of $16,130 - and includes all previously mentioned standards, plus power windows/locks, ABS, and a little more horsepower.
Like always, you can add flashier trim, automatic adjustments in the seating and mirrors, sunroof, and plenty of other goodies that will still keep your 2012 Nissan Versa in an affordable price range.
