We've been talking about the Bugatti Veyron successor for what feels like an eternity but our spies have finally snapped photos of the highly-anticipated model.

We've been talking about the Bugatti Veyron successor for what feels like an eternity but our spies have finally snapped photos of the highly-anticipated model.

Caught in Southern Europe, the mule is based on the Veyron Super Sport and features a modified rear bumper and unique alloy wheels. The rear deck lid panel has also been removed to allow for easier access to data logging equipment.

The prototype's interior largely carries over but we can see an assortment of testing equipment and emergency buttons. The model also has a Volkswagen-sourced steering wheel but, rest assured, that won't be used on the production model.

Bugatti has been coy on specifications but the model - which could be called the Chiron - is expected to be significantly lighter than its predecessor. Sources have also hinted the car could produce up to 1,500 PS (1,103 kW) but executives have only confirmed it will "redefine the benchmarks" set by the Veyron.
