Cut engine idling
Engines left running during deliveries and unloading were burning fuel for no return.

Fuel Saving Case Study · Saudi Arabia
Up to 35% less fuel on a live delivery fleet
How a leading beverage distributor in Riyadh cut fuel use on 20 Isuzu trucks in a six week live trial: 35% saved with Auto Engine Cut-Off and 17% with Speed Limiters, as reported by the client's own fleet team.

The Challenge
Fuel lost at the kerb and on the open road
The client's distribution trucks spend the day between delivery stops and city roads. Engines left idling during unloading and uncontrolled speeds between drops were both driving avoidable fuel consumption.
Any solution also had to fit how the fleet works: installed around a live delivery schedule, and fitted directly by the technology provider.
Control vehicle speed
Capped speeds to support fuel efficiency, road safety and fleet discipline.
Keep deliveries moving
Every installation had to fit around the active distribution schedule.
Fitted by the maker
The client wanted Resolute Dynamics technicians on site, not remote fitment training.
Technology
Two systems, each aimed at one source of waste
Switch between the two technologies to see what each one controls and what it delivered in the trial.
Speed Limiter

Auto Engine Cut-Off

Trial Design
One yard, two groups, one fair comparison
The client split 20 Isuzu trucks into two groups of ten. Both groups ran their usual delivery routes from the same Riyadh yard, so each technology was judged on its own merits.

- Back in serviceReturned to normal operation
On Site in Riyadh
Our senior technical team travelled to Saudi Arabia and completed every installation at the client's distribution yard, starting in the afternoon and releasing each truck only when the delivery schedule allowed.
The client's Transport Supervisor coordinated operations, while their Lead Mechanic lined up vehicles and shared practical insight on each truck's condition, which made every fitment faster to plan.
Drivers were supportive throughout, and every truck passed a road test before returning to normal duties.
Results
What the client's fleet review reported
After approximately six weeks of normal operation, the analysis was led by the client's National Fleet Manager. Here is fuel use per group, with the start of the trial set at a full tank of 100.
