Chevrolet has already confirmed that its new 2014 SS sports sedan, the American cousin of the upcoming VF series Holden Commodore, will be making its official debut just prior to the Daytona 500 next February. Now it’s been revealed that the long-awaited VF Commodore will be revealed at the same time as the Chevy SS, with the covers set to come off both cars on February 21, 2013.

Previously, the VF Commodore was expected to be revealed towards the end of this year. Instead, it will debut next February along with the Chevy SS before going on sale later that same year in the Australian market. The information was revealed by Holden boss Mike Devereux recently to Drive.

"We'll launch them on the same day then. We'll make it happen," he said.

Devereux went on to explain that the attention afforded to the cars from tens of millions of NASCAR viewers is an opportunity not to be missed, and that it should be a boost to both the Chevrolet and Holden brands.

Few details about the actual cars are known, though the Commodore and Chevy SS it will spawn will both benefit from significant technology advances including innovations in lightweight construction and fuel efficiency. This is expected to include increased use of aluminum in their construction as well as aerodynamic styling. Underpinning the cars will be GM’s rear-wheel drive Zeta platform, the same platform found in the Chevrolet Camaro muscle car and the Commodore’s long-wheelbase cousin, the Caprice, which is already on sale in the U.S. as the Chevrolet Caprice PPV police cruiser.

Specific updates should include improved suspension, electric power steering, an electric parking brake, collision warning and blind-spot detection systems, and keyless engine start. Expect a choice of V-6 and V-8 engines for the Commodore, while the SS is likely to come exclusively with a V-8. A V-6 option may be added to the SS range if demand is sufficient.
