Under the menacing bodywork is a 4.0-litre twin-turbo V8 producing "in excess of 550bhp", which is sent to the rear wheels via a six-speed sequential transmission with a carbonfibre propshaft and limited-slip diff.
The car's debut will be in the first round of the Blancpain GT Series Endurance Cup at Monza, where it will aim to begin a defence of the 2017 crown won by the old vehicle.
The new Continental GT3 is now being developed and will be ready-to-race for the 2018 season.
Bentley hasn't revealed exact weight figures, but says the new GT3 will weigh "significantly less than 1300 kg (2866 pounds)".
Bentley's new Continental GT3 race auto has been unveiled, and it takes after the newly redesigned Continental road vehicle.
"The new vehicle leaves no area or system untouched in the search for even better performance, and the early test results are promising".
With the IGTC season-opening Liqui-Moly Bathurst 12 Hour running to previous-year GT3 homologations, the new vehicle will make its competition debut in the Endurance Cup season-opener at Monza in April, with the team set to run its current-generation model in Australia.
'The new Continental GT road auto has proved to be a great starting point for the development of a new racer, and the engineering development work is true to Bentley's impeccable standards'. Customer sales of the GT3 start June 2018, though Bentley has yet to reveal pricing.
Look for the new Bentley Continental GT3 to appear on-track in various racing series starting next year.
Bentley says testing sessions are already underway, and plans to run a full 24-hour race simulation with the vehicle to make sure it's up for the challenge of modern endurance racing.
The team is yet to announce its 2018 driver lineup.
