mine turn , thanks bro docrayboy for organizing the event.
Event review :
It was great but was thought to have a engine / technical introduction but did not happen or i was out doing test drive maybe ? based on earlier planing
the car,
i was lucky because i sign up to test drive 520i but end up test both back 2 back thanks to SA Alex,
Now i own a f10 520d so my review can be on all 3 car except 535i . and i am using BUTT DYNO no real fact and figure , i did not time it or anything
520i
performance :
Torque based on paper was available from 1250 rpm onwards because of twin scroll , but when i drive it in Sport mode ( chassis and drive train ) i felt the power/ torque only come in after 3000+ more or less around 4/5k rpm. it was a strange thing to see again after converted to oil burner when i see the rpm reach 7/8k before change gear. also 1st time i tried comfort+ and i tried to floor it the RPM max at 3 only and change gear to prevent sudden acceleration
Sound :
the Petrol potter is quieter than my 520d 4 potter. the chattering sound is there but lower tone , unlike 520d which i call it sound like lorry
. a "+" here over 520d
consumption :
no need to compare lar , 520d win every time even sport mode also guilt free . so no comment
feature :
Auto stop start is there but a little bit irritating can be turn off on demand . if turn off the 6.4/l will not be achievable . IAS is there nothing to shout about.
528i
Performance :
again 2 mode confort and sport ( chasis and drivetrain ) , responsive of engine is there , torque / power is available at 3k rpm not like 520i which i felt lag. much more driver oriented car and aggressive. agreed with bro pussy the paddleshift in this case because of 8 gear is more or less to help you drop gear. too much gear to play around.
Sound :
same like 520i not much chattering . acceptable . performance sound much better than 520i , this was agreed by the group in my test drive. i asked the sa is it like M5 with built in sound to fake the roar.
consumption
worst
feature : 528i come with additional HUD display cool but sometime weird especially for specky like me , i tend to focus on the hud too much. VDO display is half LCD unlike 520i and 520d only quarter lcd. M body kit and 18" wheel. M sport trim , Msport seat and Steering wheel . so the 49k over 520i is worth it. I drive have additional function
overall summary
all 520i / 520d / 528i are fine car but really depend on what you want.
520i good all rounder ( urban driving /non performance ) sound decent unlike 520d lorry . ( tai tai car )
520d urban performance ( with so much torque , need i say more overtake in start stop traffic is a breeze ) ( daily driving )
528i Good highway car ( soo much toy and you get m sport kit ) , the 18 inch on sport plus is too harsh compare with 17" of 520. maybe change RFT it be better.
for me i stick with my 520D cuz after test drive that 2 beuty i love my diesel more ! , if you want performance non stop guilt free -> 520d , will get either vector / hartge / ac / chipexpress ECU when my warranty expired . cuz 528 remind me of what a remap of ECU can do your car
if undecided between 520i and 528i , get 528 the 49k different of 528 is worth it because officially Mkit + wheel cost more than that
