Just got my new S60 2.0T for about 2 months in Hong Kong and was satisfied with the performance that it delivered.

However, when releasing the foot brake after temporarily stopping at the traffic light on a steep road, I noticed that the S60 will slightly roll-backward. This also happens when engaging a reverse-gear in a down-hill road. Observations indicated the same problem occurs no matter how many passengers are on board.

Technicans from locally Volvo dealer explained that this is normal and is related to the new gear-box design for the S60/S80. The roll-backward effect can be circumvent by using the hand-brake. Is it true? Any one out there has similar experience with the S60 or S80?

Thanks.

The technicians are correct. The new Volvo automatic transmissions have something called "Neutral Grade Control". This system basically 'disengages' the transmission output to drive-shaft when the car comes to a stop to prevent wear and tear. If you are on a hill pointing upwards, the car will roll back slightly if you take your foot off of the brake pedal. The instant the drive-by-wire system detects a throttle input, the car goes engages to normal operating conditions.
