yes they are, but they are better known for their smaller scales, and they used to be under the HPI brand before getting cut loose by the company to be on their own as ignition model.
but after this last one, with the uneven quality control, high prices and there being only one distributor in the US (because they are no longer part of HPI) which makes it so difficult to get on this side of the world... it's not worth it
having said that, i've seen posts online where others buy these as upgrade projects knowing there are issues to be fixed, and then add upon them, from making them a rolling chassis (it's strictly a non-roller static model straight out of the box) or add lighting to it because resin models have no opening parts so it's a hollow shell inside with lots of room to do electronics... and they turn out pretty spectacular.
i'm going to have to search youtube again for the video i saw of one... it had engine sounds (recorded from gran turismo onto a sound card), and interior/exterior lighting (with working turn signals, etc.). it was part of a diorama that replicated a scene from gran turismo (the builder had a screen capture on a computer monitor in the background).
