In the Power BI, you can just use the table chart to display as a new column because this column is filtered by the selection of a slicer. I think you can create a new table and a slicer to filter a table chart to achieve your requirement, you can follow my steps:
Create a calculated table:
Car = SUMMARIZE('Table1',Table1[Car])
Create a measure like this:
var _selectedcolumn=CALCULATE(MAX('Table1'[New Column]),FILTER(ALL('Table1'),[Car]=SELECTEDVALUE('Car'[Car])))
Then you can create a car slicer to place the column in the new table and a table chart to set the filter and summarize type like this:
