PACCAR have invested two years in making a new Active Cab Entry system to help drivers get in and out of their cabs easier. The trials are still underway but a prototype was unveiled at the Brisbane Truck Show on a Kenworth K200 cab over model. The step will retract automatically if you drive off with it open, it has sensors to stop it from opening if there's a chance it will hit something and it is operated via a switch only. It will be introduced later this year as an option. This is an automated step system, whereby a set of wide, non-slip steps folds out beneath the door, making it easier to enter and exit the vehicle. Scheduled for production release later in 2013, the ACE system is an ideal option for drivers on shorter distribution tasks requiring more frequent cab entry and exit.
