I heard that the 4AT transmission has serious jerking issues. Can any car owners share their real experiences?

4AT's fuel consumption is high. It's better to buy the Rapid.

What is the RPM of the Kia Pegas when driving at 120 km/h on the highway?

You can make the 1st and 2nd gear more distinct. For higher gears, if you coordinate the clutch well, it's basically seamless!

Alright.

I won't buy this car without a central locking switch. Having to get out to open a door is just annoying.

Still okay.

The hesitation in the Santana 1.5 with the 6AT is stronger than this 4AT, but it is much more fuel efficient, saving over a liter per 100 kilometers compared to this 4AT.

I really can't tell if it jerks or not. Just think about it, running at 90 km/h in 4th gear—how many revs and how much fuel does that take? If you really like automatic transmissions, why not spend a bit more and get a 6AT?

Yes, but it's not very obvious.

When I start at low speeds and shift gears, there's a bit of an issue. If I accelerate slowly, it doesn't happen.
