On the contrary, I test drove the 520d during Chinese new year open event and find that the handling is beautifully poised around the curvy Sg besi Highway from AB Sg besi to Lakefields and back. Slammed the gear into manual and it hugged the roads beautifully. I honestly couldn't achieve it with the a6h.

However, my wife wasn't impressed with the interior and back space with were comparatively mediocre while I have a bone to pick with the puny steering wheel and a relatively plain cockpit.

To me, the master stroke by euroMobil was that they included the super sexy LED headlights that has given the a6h that distinctly premium and exclusive look. It was to have been a $14k option on the regular a6

Yes in general I do believe that a proper RWD BMW can handle better, but not by much in 99% of normal driving condition.

Last Sunday I went to outstation with an uncle, in his F10 528i 2.0 turbo. I drove his car for about 1 hour, on highway the power delivery did seem to be more responsive than our A6h. Tyre noise is louder blame to RF tyre.

Once I turned into normal road, taking an round about and I immediately felt that the 528 was too softly sprung. Not as composed as our car. Turned on the sport suspension mode the throttle was also adjusted together then the gear change too aggressive, not comfy for passengers. ( 4 of us in that car ) at the end I put back to comfort mode to slow down. Emm.... Not all that good.

And on top of it, it is 130k more expensive than my A6h, no sunroof, no LED light, higher FC. So I don't think I will miss it much.

Yes, in normal driving mode, recharging is more subtle.. If you want it to charge to near full, pull the gear down to sports mode and the charging will be more agressive.

Also, I find that one can charge the battery more when braking progressively within the regenerative braking zone (the green zone below the 0 line in the power meter) than comparatively, doing harder braking in shorter distances.  What I meant is that, say you see traffic lights far ahead approaching.  You can either
1- coast to stop, the regen meter shows very subtle charging taking place
2 - feather the brake pedal lightly WITHIN the regen charging zone (not exceeding it).  What happens now is that recharging is taking place more efficiently without mechanical braking and hence loss of energy (since most of the energy is now used to recharging the batteries)
3- depress the brake pedal more aggressively as you approach the lights.  The result, mechanical braking taking place and loss of energy .

So far, I've been quite happy with car.  Docile when you want it but good power available on tap when you need.  Just that the handling department is nowhere near BMW

the last discussion topic has something on your question.
yes, the battery rarely charges to FULL, but on long trips you should be able to experience it.

Battery never fully charged

Hi,
I realized that the battery is never fully charged and I can't use ev mode for more than a few hundred meters on city driving.
Is that normal?
Share your thoughts.

Regards,
Energy
