However, rather than there being one overwhelming design factor that makes the RB19 stand out, the key appears to be a number of smaller details that are all contributing to the overall success.
One design aspect that proves this is the RB19's chassis, with a distinctive V-shaped profile applied to the lower half of the bulkhead.
It is a feature that builds on the tapered profile seen on its predecessor, which was already more contoured than many of the more square-chin variants seen elsewhere up and down the grid.
