irrelevant bro.
both have the same transmission, and for LCI 320i, likely 325i has the better ZF shifter. still, the IL6 has better low down power for zero-to-traffic-light drag race. 325i also has DISA + Double VANOS + Valvetronic. no matter how the 320i is modded, it is still not going to gain 62 or so horses, unless it is FI-ed.
i would agree that the real deal is with the driver skills, but here in SG, no need. even sonata taxi also can win you even if you drive a lambo. how? he just have to accelerate before the light turns green and drive in the middle of two lanes in front of you. you also lan lan.
