| Description of the problem | I purchased my optima sx turbo with less than 50 miles on it. I got the turbo with 274 hp because it was the closest i could get to a hot rod with four doors. I have send this information to kia in hopes of resolution. The car's acceleration is fantastic, especially from 40-50 with gas peddle floored. Here is the problem. The front end rises and the weight shift makes the car feel like you are about to pull a wheelie. At this point i question the traction of the front tires. It cannot be the same as with no severe acceleration. This takes away the reason i bought the car with this specific engine. Also think about this scenario. A family is driving this car on the highway in the rain. They want to pass an 18 wheeler going up a grade. Acceleration is increased and with weight shifted back off the front wheels, they crash. The car needs either stiffer suspension or ability to change the suspension. When i floor it, the weight ratios over all wheels must not change. |
