The Giant Killer

Do you have a Giant Killer? For sure, we do! With the amazing 550 V8 we have combined the philosophies of the Porsche models:

  • 356,
  • 550, and
  • 718, especially the RS 61 with V8 engine,

    with our models:

  • 356 V8, the Outlaw,
  • Electron B, and
  • Cayman GT and Boxster GT

    for creating a pure driving machine that redefines the pure fun™ in a totally new way.

    As usual, we offer all exterior parts made out of Pure Carbon™ and our Carbon Hemp™, as well as the rear and side windows made out of polycarbonate, besides further lightweight components like the racing headlights.

    Carbon Hemp™ is also used for the fabricating of the interior parts as an option.

    For the drivetrain we have chosen a 2.8 to 3.0-liter 75° 32 valve V8 engine based on two engines of the Hayabusa motorcycle by the manufacturer Suzuki coupled to one of our Active Transmissions™ featuring a 6 speed sequential race gearbox with an adjustable lim- ited slip differential that is mounted transversely, a high-performance titanium exhaust system, as well as an optional carbon-carbon or ceramic composite brake system.
