0-100 Times:

Civic Oriel X: 9.58
Sportage: 10.6 sec
All taken from Shaheel Shahzad Youtube Channel. Sonata's acceleration is not bad at all considering this. Also Motorports Pakistan has done a drag race and the Sonata 2.0 is quicker than Oriel X1 from 0-100, after 100 it's a totally different story same for the rolling race, but the kick down is much better on Sonata. It doesn't seem like the acceleration is slow on the 2.0 Sonata, it's fairly adequate. Top end seems weak but not that much, the civic crosses the 2.0 Sonata after 155-160, so not bad and for someone who doesn't push their cars this hard, it seems perfectly alright.
P.S: I don't own any of the above mentioned cars
