The images were quickly taken down, but not before fans on the Camaro6 forum managed to save a copy and republish them.
While the images are low resolution they do show that the sixth-generation Camaro convertible holds no surprises with a folding soft top in place of the coupe's metal roof. We also know, from the teaser video (top), that the electrically operated top is able to retract when the car is in motion.
It's expected that the new convertible will be offered with the same selection of engines as the coupe, which includes four-, six- and eight-cylinder options.
At present the Camaro range has been confirmed with a 205kW/400Nm 2.0-litre turbocharged four-cylinder engine, a 250kW/385Nm 3.6-litre V6 and a 339kW/617Nm 6.2-litre V8.
In the coupe range, these engines are mated to either a six-speed manual or an eight-speed automatic, both of which are connected to the rear wheels.
The new Camaro is smaller than the outgoing model, and is based on the Alpha rear-wheel drive platform that's shared with the Cadillac ATS and CTS.
Thanks to the slightly reduced dimensions and the use of aluminium components, and other measures, the weight of the coupe has been reduced by around 90 kilograms. It's unknown, at this stage, what type of weight penalty the new convertible carries.
The new Camaro convertible will be unveiled on June 24, US time.
At the launch of the coupe, Holden confirmed that the new Camaro won't be built in right-hand drive. This leaves the identity of the Holden-badged rear-wheel drive V8 vehicle, which will go on sale after the closure of its Australian factories, unclear.
