The introductory 2009 Kia Borrego is the LX V6, a 2WD model that offers a 3.8L V6 engine that produces 276 hp. This engine comes standard paired to a five-speed automatic transmission. The next trim, the EX V6, offers the same engine and transmission configuration. The Environmental Protection Agency (EPA) estimates that the fuel economy ratings for these two vehicles are 17 mpg in the city and 21 mpg when on the highway for a combined rating of 18 mpg.
The next two trim levels are the 2009 Kia Borrego LX V6 4WD and the EX V6 4WD. They both have the same 3.8L V6 engine that produces 276 hp and five-speed automatic transmission. However, the four-wheel drive (4WD) system does affect the fuel economy rating slightly. For these two models the EPA fuel economy rating is 16 mpg in the city and 21 mpg when driving on the highway for a combined rating of 18 mpg.
Stepping up to the next trim, we find the 2009 Kia Borrego EX V8 2WD. This model offers a 4.6L V8 engine that produces 337 hp. The engine is paired to a six-speed automatic transmission. For this model, the EPA fuel economy rating comes in at 15 mpg in the city and 22 mpg when driving on the highway. This creates a combined rating of 18 mpg – the same combined rating as all the earlier trims.
The 2009 Kia Borrego LX V8 4WD and the EX V8 4Wd trims both have the same 4.6L V8 engine that produces 337 hp and both come paired to a six-speed automatic transmission. As they are both four-wheel drive models, their fuel economy will be slightly less than the previous 2WD model. In this case, the fuel economy rating comes in at 15 mpg in the city and 20 mpg when driving on the highway. This then gives a combined rating of 17 mpg.
