MPG: 29/41; Base Price $24,390. The only midsize sedan among the top-10 fuel-sippers for 2018 – at least with the base 2.5-liter four-cylinder engine and eight-speed automatic transmission (a V6 is also offered) – the Toyota Camry is redesigned for 2018 with added style and substance. Those looking for a Camry with even better fuel economy might consider the gas/electric Hybrid model with as much as 51/53 mpg.
