Toyota RV-1 (a recreational sporty wagon).
Shown at the 1971 Tokyo Motor Show.
This appears to be based on the prototype of the Celica liftback, released in Jan 1973.
The nose of the car looks more like the revised Celica nose from 1973, without the sloping indicators of the 1970-1972 celica.
The doors are reported to be gullwings, but I am not sure if they meant the main doors or the rear side windows.
Production Celica doors do not have window frames, so they probably meant the rear side windows.
The trailer included a tent and camping equipment. Its top cover could be used as a boat and could accept an outboard motor. This trailer was also shown (slightly modified and called the Marinetta) at the 1972 Tokyo Motor Show behind a standard Celica coupe.
The RV-1 was a 2-door wagon concept car based on the Celica and shown during the 1971 Tokyo Motor Show.
The front had vertical corners instead of the normal Celica's sloping park lights (indicator lights in some markets). The bonnet was also extended forward to match. An unusual grill was used featuring large round holes instead of the more common slats or hexagonal holes.
The front windows and the doors remained the same as the Celica but the roof line was extended to cover the rear passenger seats and then continued as a thin spine to the rear of the car. On each side of the spine a centre hinged gull wing window completed the roof and continued down to the waistline. A large integral roll bar completed the rear and also held up the rear of the roof spine. The tail lights and rear indicators shown through many small round holes in the rear face of the bodywork. Unusually for Celicas, the rear bumper had cut-outs to house red reflectors and reversing lights. A 1 metre wide tail gate with a frameless wind-down window occupied the centre of the rear. The centre section of the bumper moved with the tail gate instead of being fixed directly to the body.
A tow bar was fitted so that it could be shown with the Marinetta.
The RV-1 was designed a part of a recreational vehicle system that included the RV-1 car, the Marinetta trailer (which included a fibreglass dinghy), a 5-person inflatable tent and a jet ski on its own trailer.
The SV-1 Celica liftback prototype
was also shown at the same time at the 1971 Tokyo Motor Show. The RV-1 never went into production but the SV-1 did.
was a concept trailer made by Toyota and shown during the 1971 Tokyo Motor Show behind the RV-1 concept car.
The bottom half was a conventional single axle small trailer made from fibreglass. For the exhibit, it was shown with one inflatable tent next to it and another tent packed inside. The top half of the trailer was a small boat mounted upside-down, with the bottom half of the trailer matching the boat shape along their joining edges. The boat used an outboard motor that was could be disconnected and stowed in the bottom half when the halves were reassembled for towing. The exterior was painted white with a black stripe and the interior was painted bright orange.
A jet ski and its trailer were also shown alongside the Marinetta at the show stand.
