Full throttle

I noticed today that of you push full throttle that there's a r├ęsistance/stop

If you push harder you feel ├* little click and it seems that my autobox pushes my engine even ├* little more...

It deels like extra power... Did any one else notice this?

It's the kick down mode you feel. Read about it here.

Strange - I have now tested it with both IE and Chrome and both works here.

We can try this way.

The kickdown feature has been with us for many years in auto transmissions. All part of driving an auto transmission, the same as the brake pedal can be used to get down changes for engine braking, or the throttle can be modulated to hold a gear in some circumstances.

Using kickdown doesn't give more engine power, as full throttle (WOT) does that anyway, it is simply a way to instigate a down change (or more) on the throttle pedal.

Garage List
If you're cruising along on a flat road and you suddenly slam the throttle, but not beyond the point of resistance, will it stay in the same gear, or could it still change down?

Smashing the throttle without pressing that 'button' will still change gears down. Depending on what mode you're in, the number of gears it shifts down changes. It does it in my base Mazda 6, does it in my passat, R30, jag S-type, fortuner.... And almost all automatics.

Actually, that button does deal out a little more torque from the engine. BMW always rates their engines at Xnm Torque with X+Ynm of over boost for 5 seconds.

So that button does give more torque = slightly faster acceleration.

It could still change down. Depends on your speed though.
