An undisguised Bugatti Chiron prototype has been spotted testing, which gives us a more detailed look at the upcoming supercar. Uploaded on Instagram after being snapped by Stefania Piffer, the picture shows the Chiron in black exterior paint.

Only the rear three quarters of the Chiron are visible. The taillights are not production-spec and the side of the car bares similarities to the Veyron with the marque’s side signature line. However, the flowing lines at the rear give the Chiron its own unique look as does the new diffuser and redesigned tailpipes. The design of the vehicle will be based on the Vision Gran Turismo and previously, the front of the Chiron has also been snapped.

It is said that the Chiron will feature the same basic quad-turbocharged 8.0-litre W16 engine as the Veyron. However, boost will be increased and at least two of the turbos will be electrically driven units. As a result, the new French hypercar should pump out 1500 hp and consequently be capable of hitting 100 km/h in just over 2 seconds before topping out at over 450 km/h. It will reportedly cost $2.5 million and Bugatti has promised that the Chiron will be more track-friendly than the Veyron.
