GTA³™ Ultra

The GTA³ Ultra is the ultra-progressive, ultra-passionate, and ultra-performant version of our GTA³ coupé that has many outstanding features, which are the:

  • ultra lightweight chassis,
  • ultra sporty exterior and interior with eye candy factor,
  • ultra revs engine with extrem vividness and goose bumps effect, and
  • ultra agile suspension with an elaborately designed geometry.

    The GTA³ Ultra comes either with standard components of the RS and clubsport lines by the factory, or as a bare bone that the owner completes with assembled parts in different qualities of her/his choice for the:

  • exterior,
  • interior, and
  • drivetrain.

    Exterior Options
    For the exterior we apply parts made out of Pure Carbon™, and our Carbon Fiber-Reinforced Plastics for the:

  • roof,
  • fenders,
  • doors,
  • bonnets,
  • bumpers,
  • side skirts,
  • diffusor,
  • wings,
  • rims, and
  • other exterior parts,

    and polycarbonate for the:

  • rear window and
  • side windows,

    besides lightweight components, as the:

  • racing windscreen made out of a thinner laminated safety glass,
  • racing headlights, and
  • quick release fasteners for the hoods,

    and for sure additional stylistic elements, like the:

  • high-gloss paint jobs,
  • theme oriented decals, and
  • Hot Wheels® styles, as well as
  • fine leather and
  • further high-quality materials wherever it fits.

    Interior Options
    Fine Carbon™, Carbon Hemp™, Carbon Bamboo™, and Carbon Coconut™ are also used for the fabrication of the:

  • seats and
  • dashboard,

    while we are also offering as performance options:

  • steering wheels,
  • anti-noise system for cancelling all kinds of noise,
  • racing accumulator,
  • racing equipement, and
  • other interior racing parts.

    As the ultimative step, we offer the following engines:

  • eventually later Volkswagen→Audi→Ducati
    • V4 16 valve with 1.0 to 1.05-liter 90° of the model Desmosedici RR,
    • V8 32 valve with 2.0 to 2.1-liter 90° based on two Desmosedici RR engines,
    • V12 48 valve with 3.0 to 3.2-liter 90° based on three Desmosedici RR engines,
    • V2 8 valve with 1.2-liter 90° of the model 1199 Panigale, and
    • V4 16 valve with 2.4-liter 90° based on two 1199 Panigale engines,
    • V6 24 valve 3.6-liter 90° based on three 1199 Panigale engines,
  • Suzuki
    • R4 16 valve with 1.4 to 1.5-liter 75° of the model Hayabusa and
    • V8 32 valve 2.8 to 3.0-liter 75° based on two Hayabusa engines
  • Engine on Demand™ option for the connection of two and three engines.

    Due to the very small dimensions of the drivetrain and for a highly optimized weight distribution, we mount the engines transversely in front of the rear axle. Further optimizations on the side of the drivetrain are achievable with the:

  • Active Transmission™ based on our Modular Transmission™ System, and featuring:
    • 6 speed,
    • sequential race gearbox, and
    • single clutch or dual clutch,
  • high-performance exhaust system with optional side pipes made of
    • titanium or
    • Inconel®,
    as well as
  • ultra-performance brake system using brake discs made of
    • carbon carbon or
    • ceramic composite.
