The British carmaker is set to launch the Corvelette Grand Sport next year.
The latest version of the luxury sedan is expected to come with a base price of £75,000.
The company said the sedan will be powered by a 2.0-litre V6 petrol engine and have a top speed of 250km/h.
This will be the first Corveletta to feature the new 3.5-litres V6.
“The Corveletas Grand Sport will be one of the most luxurious sports cars on the market,” Corvelettes chief executive, David Smith, said.
“Corvettes offer exceptional performance and class-leading safety features.”
The sedan will feature an interior of leather, leather trim and an all-new exterior design, which will be inspired by the Aston Martin DB5.
The Corvelets Grand Sport is expected by early 2018.
