This is the car that comes at the very end of my sports cars list alphabetically! though I suspect others on here may know of others.
Zynki Power Le Mans Turbo, from Germany, circa 2000/2003, 5.5 V10, 558bhp, 990kg, apparently BMW based but the builder seems to like comparing it to Porsches (Carrera GT, 959, 718 etc)
The designer/builder/seller has a website on this car
