9. 2012 Hyundai Sonata: 205,006 Cars Through October 2012
Yes, there’s been plenty of scuttlebutt after the EPA cut fuel economy estimates across most of Hyundai/Kia’s product portfolio. The standard Sonata’s ratings were unaffected, and it remains a fairly fuel-efficient midsize sedan – and, with just over 205,000 sold through October, a fairly popular one at that.
Hyundai was one of the first major players in the midsize segment to adopt an all-four engine strategy. Take a look: there aren’t any six-cylinder models to be found in today’s Sonata. Most 2012 Sonatas sold are equipped with a 2.4-liter I-4, which is available with either six-speed manual or a six-speed automatic transmission. Either way, that combination is good enough for the EPA to rate at 24 mpg in the city, and 35 mpg on the highway. Want more power? A turbocharged 2.0-liter I-4 is also available, albeit only with the six-speed automatic. That combination is rated at 22/34 mpg city/highway. The Sonata Hybrid pairs a slightly different 2.4-liter I-4 with a 40-hp electric motor, and earns a 34/39 mpg rating from the EPA.
