Bugatti just sold its final Veyron, which means full attention for the crew in Molsheim, France has turned to the car’s successor, a new supercar tipped to be called the Chiron and packing a hybrid powertrain. Early test mules for the car have been spotted, but no new details could be ascertained from these as they still resemble the original Veyron.

Some things we do know about the car is that it will feature an upgraded version of the Veyron’s quad-turbocharged 8.0-liter W-16 engine. The engine currently produces 1,184 horsepower in its most potent setting but with the addition of a new fuel injection system, an integrated electric motor, and perhaps even electrically-driven turbochargers, we could see output boosted significantly.

CAR is reporting that output of the Veyron successor will register at a staggering 1,500 horsepower and 1,106 pound-feet of torque. While these might seem like impossible numbers for a production car, recall that rival supercar marque Koenigsegg has just launched its Regera with 1,500 hp and 1,475 lb-ft of torque.

And with 1,500 hp on tap, the Veyron successor is said to be capable of accelerating from 0-60 mph in just 2.0 seconds, down from 2.5 seconds in the 1,184-hp Veyron Super Sport. Top speed, meanwhile, is said to be as high as 288 mph, or about 20 mph faster than the land speed record-holding Veyron Super Sport.

The unveiling of the Veyron successor, whatever it's called, is expected to take place next year.
