Re: Inline 6 (523) vs Inline 4 twin turbo (520)
Anyway, I have been enjoying the smooth acceleration for the last 3 weeks...
Suddenly today, the gear shift from 2nd to 3rd dragged till above 2000rpm to make the shift even as I step very gently on accelerator. Usually gear shift at around 1500 to 1800rpm.
Is it because I over accelerated or something? Please do provide some advice.
Thanks.

I still feel the 8sp auto takes a while to respond to throttle input and because of the narrow gear ratio if I want to overtake or do something smilar it will want to shift down TWO gears.
I usually drive in manual steptronic mode now and just shift myself, especially during overtaking and even just getting around corners. When in 'D' the car tends to keep the rpm too low for fuel economy and the engine strains a little trying to pull the car especially if you are taking a bend or those filter lanes that go uphill.
After driving in manual steptronic mode I find the 523i more than enough for SG roads... it takes off on command when in the right gear and I am still getting on average ~9.0km/l given 50/50 city/hway driving.

Don't play play with BMW diesel. Since the days of E39 530D, i have been amazed by torque from this oil burner. I have seen it in Malaysia how smooth it is.
520D definitely can chiet 520 as 520D got 110NM torque. Chevy Epica has as much torque as 520, so what do u think?Shev;901835 said:

The 8 speeder was meant for high speed driving. The last 2 gear is juz overdrive.detach8;901869 said:

Nothing wrong. Car is very intelligent. Probably a combination of how you were driving and road condition.
If you are going very steep uphill, car will only shift to 3rd at around 3000rpm, that is even if you step very very gently. Similarly, if accelerating up a slight gradient slope at 90, car die die will never shift from 7th to 8th no matter how gentle you go. If you are starting off a very steep downhill, car will use engine brake by holding gear, untill you reach about 50km/hr or so. Just something that I experience on my daily drive around my little town built around a hill.

Torque is over-rated, at least that was how I felt when riding in epicas and sonatas during my recent back to army activities. First impression was no pull, no power, even though the taxi drivers were reving the shit out of their car. I really wonder how often they change their brake pads. But then I must admit that when driven sanely, the epica(especially a new one) is really peaceful, smooth and comfortable.
Torque is NOTHING without horsepower. Adding more torque makes no difference once you have enough torque.
Diesel will only beat petrol if diesel is in power range while the petrol is not. For instance comparing the acceleration from 60-80km/hr in 7th gear. Then again, most of us(and the transmission) tend to do that for daily driving in the name of fuel consumption.
