Dubbed the XX, this model is likely to feature significant weight savings and aerodynamic upgrades. However, officials have already confirmed it would be "difficult" to extract any more power from LaFerrari’s current combined 950bhp hybrid output, saying this new model will have "more or less" the same power.
Previous early test mules, spotted at the Nürburgring, featured an unpainted body with its traditional windows replaced by sliding plastic units.
This latest test mule was caught at Ferrari's Fiorano test track, and features new a camouflaged body. The biggest styling change is the adoption of a new, split rear spoiler, which gives the car a far more aggressive look. A new front splitter can also be seen.
Our spies report the new car setting a time of around 6min 35 seconds around the 'Ring, which could potentially mean a new lap record for production cars.
