Vehicle Benchmarking

A specific, distinctive vehicle attribute branding is essential to make cars unique and competitive. Benchmarking vehicles in the competitive environment helps to understand and to strengthen or improve the potential of new models.

AVL offers a comprehensive vehicle benchmarking analysis of the most important, recently released passenger cars. The objective assessment delivers an overview of results for ten main attributes in a competitive scatter bands.

BMW X5 xDrive40eo Pedal map shows good agility and

consistency

o Consistent and reproducible ICE starts

o ICE start mostly during ratio change phase when down shifting quick start with strong Belt starter

o Less disturbance in acceleration feel at ICE start

Volvo XC90 T8o Pedal map shows low consistency, quite

harsh o Inconsistent and sometimes early ICE

starts

o Big disturbances in acceleration feel when ICE starts and down shifts occur
