I just GOOGLED this query, and all these cam up.
In real life, the Ioniq 5 is 63-inches tall ( 1600.2mm )
The 'Shorty' is 62-inches ( 1574.8mm )
Technically, your drawings need to reflect this slight difference.
And you'll need to superimpose a receiver-hitch-mounted ball extension behind the Ioniq's rear bumper in order to achieve the proper spacing.
