Yes, because the manufacturer provides a type approval report that covers all FN2's
However, for the FD2 (et al) you have to use a model report instead; these are invariably prepared by individuals/import companies who submit a car for test by VOSA, and as such there are variances between reports. Litchfields managed to get their test car through as a band F, but I know of another report shows the car as a band G.
Therefore depending on which report is submitted when your car is SVA'd depends on the tax bracket it ends up in.
