The fifth-generation Toyota Supra will be unveiled at the 2019 Detroit motor show, which begins on January 14.
Although the company has since taken down the comment, it was captured by a user on the SupraMkV.com forum.
Toyota has also begun taking pre-orders for the vehicle in major European markets. In order to secure one of the first 900 Supras in Europe, buyers will need to put down a €1000 ($1620) deposit.
The company's European arm says members of the "Supra 900 Club" will have "access to exclusive content, rewards and experiences" as they wait for their cars to arrive in the northern autumn.
Although the Z4 and Supra share many visible and under-the-skin components, each car will have its own unique design and tuning. The two-seat Supra will initially be available with a 3.0-litre turbocharged straight-six engine, rear-wheel drive and an active differential.
When CarAdvice drove a late-stage prototype last month, Toyota Australia confirmed the new Supra will go on sale Down Under during the third quarter of 2019.
