Surely you know Liberty Walk’s work by now? The crazy Japanese tuner obsessed with running a bandsaw through the arches of supercars represents the epitome of Marmite tuning – you either love LW’s work or loathe it. Prepare yourself then, for things to get a lot more Marmite-y…

Kato-San and his crew have gone down a different route for this latest creation: grafting the face and rear of a Nissan GT-R onto a rarefied convertible kei car, the humble Daihatsu Copen.

Seemingly still obsessed with the addictive Face Swap app from a few years ago, it’s now made one of the craziest GT-R conversions to date. The FrankenCopen features Liberty Walk’s hallmarks: wide arches, ground-scraping ride height, and a paintjob that looks like you’ve accidentally mistaken it for a ready-meal and put it in the microwave.

There are no details on whether Liberty Walk has modified anything under the bonnet, but as per protocol, they’ll have a 660cc engine – a forced-induction three-pot mated to a CV transmission – to play with. Size-wise, we’re guessing it slightly bloats out the stringent Kei regs of 3,395mm long (145mm shorter than a VW Up) and 1,475mm wide.

We’ll bring you more news when we have it, and may even see it at SEMA or the Tokyo motor show later on in the year.
