What an amazing feature on the CLK!!!

Has anyone noticed how the 209 is at a standstill on an incline ( lets say if you have traffic lights on an incline/ slightly steep road). I just realized that when I took my foot of the brakes it didn't move back with the decline on the road. WOW!!!. now why didn't I get that earlier! Surprisingly this does not happen on a straight/ levelled road..or an descent ? Such a piece of mind when you are in a queue of cars at traffic lights. No worries that you'll roll back & hit the car behind you. I did notice that one has to keep the brakes on for a certain time period....few seconds perhaps.... before you achieve the "standstill" option?. It just stays glued!!!

On the other point about standstill on steep accent, I tried 4 different cars today ( other well as new Accord + a friend's account ). All 2004 models...this feature is not standard on either of them in D mode.
Try this - on a level road, take your foot off the brake in "Drive" - what happens? The car moves forward. Why? because the car is in gear and the engine is running - not rocket science. There is a specific force that is trying to move the car forward (and succeeding on a level road). Now as you incline the car (nose up), gravity is trying to pull it backwards, and the drive force is trying to move it forward. There is a range of inclines where these forces cancel out and the car stands still. The maximum incline at which the car remains stationary is dependent on the torque of the engine at idle. Our ML430 will remain stationary against our fairly steep driveway, whereas our CLK320 Cabrio used to run forward (we reverse out).

Don't confuse this with some active technology that other cars have, which actually engages the brake when you stop and disengages it again when you press the gas pedal. The CLK does not have this feature, AFAIK.

So the "feature" that you're so excited about, is simple physics. The Japanese cars simply don't have enough low-down torque to keep the car stationary against an incline.

And, as another poster noted, it is probably kinder to your drive train to use the brake in these cases.
