ANAC stands for ANAlysis Compared, a service that lets customers understand the condition of their vehicles and obtain diagnoses of problems before they happen.

Understanding what’s happening inside a vehicle isn’t simple, requiring extensive mechanical diagnosis, plenty of degreasing and all the associated downtime. Spanning buses, coaches, HGVs, lorries, light aircraft, planes and helicopters, ANAC eliminates these issues, allowing vehicle owners to gain a vehicular health check that tells them exactly what’s happening in their engines.


Compare your engine wear

Identify vehicles in which running costs can be reduced using the diagnosis report. This measures the wear coefficient of the engine compared to all identical ones in our database.

Early detection

Detect vehicle engine problems as soon as they appear and prioritise those that need urgent attention with our colour-coded diagnosis report.

Feedback to help you succeed

Discover suggested corrective actions and their probability of success based on statistical analysis of customer feedback.
