British sports car marque Morgan is gearing up to introduce a new flagship model that's set to replace the Plus Six, which ended production last year.

Known for its blend of classic design and modern engineering, Morgan is currently testing prototypes on public roads as it fine-tunes its new flagship model, the Supersport, which is set to debut on March 11.

Morgan announced on Monday that the unveiling will take place at its headquarters in Malvern, U.K., with former "Top Gear" host Richard Hammond—an avid Morgan fan—to be on hand for the presentation.

Photos of a camouflaged prototype, provided by Morgan in January, reveal a clear evolution of the brand’s signature design, albeit with a more minimalist and curvier look.

The prototype is fitted with a hard-top roof that is likely removable, just like on the Plus Six. Also retained from the Plus Six will be a turbocharged 3.0-liter inline-6 sourced from BMW. The engine delivers 335 hp in the Plus Six.

Morgan said it has developed an updated version of its CX-Generation platform that debuted in 2019 to underpin the Plus Six. However, the company hasn't revealed what updates were made for the new platform, which is known as the CXV and retains its predecessor's bonded aluminum construction.

The company also hasn't said whether the Supersport will be offered to customers in the U.S., though the recent launch of the Plus Four here suggests the new flagship will also make the trip.

Update: Details on the the new car's name and reveal date have been added to the article.
