EX–7 (1970)

The EX-7 was a 2-seat concept car made by Toyota and shown during the 1970 Tokyo Motor Show. It was an experiment (hence 'EX') to see what a supercar based on the Toyota 7 (hence '-7') racing car would be like. The mid mounted 5 L (310 cu in) engine was similar to the Toyota 7 engine except that EX-7 did not have turbochargers. The Toyota 7 had 800 bhp (597 kW; 811 PS) but the EX-7 was detuned down to 450 PS (331 kW; 444 hp) for road use. Transmission was by a manual gearbox as part of a transaxle. Double wishbone independent suspension was on all 4 wheels and vented disc brakes were used on both the front and rear. The body shape was similar to that of other supercars of the time, like the Mercedes C111, with a long flat nose blended into a long windscreen and a high rear with a vertical cutoff. The doors were shaped like a typical gull-wing door but unusually the hinge was at the rear of the roof section of the door and each door opened to the rear.

Electronics Car (1970)

A modified Corona was shown at the 1970 Tokyo Motor Show as the Electronics Car. Based on the Corona Hardtop 1700SL, it was a cutaway model showing EFI, Electric Skid Control, Electronic Automatic Transmission, air bags, monitor display and cruise control. It was not put into production but many of its components did eventually reach production in various Toyota models.

SV–1 (1971)

Shown at the Tokyo Motor Show in October–November 1971, the SV-1 was the prototype for the Celica liftback released in April 1973. The prototype was built on a TA22 GT chassis with frame number TA22-026004. This was originally built in May 1971 as a Celica TA22 GT coupe. The mechanicals of the TA22 GT were retained (1600cc 2T-G twincam engine). The front of the interior was the same as the TA22 GT except for a different fabric pattern on the seats. Electric window lifts were used (optional but rare on the TA22 GT) but the TA22 GT's optional air conditioning was not present. The rear 2 seats were individually reclining using the same reclining hinges and latches as the front seats except that the rear latches were in the middle. A centre padded vinyl console was between the 2 rear seats and the seat belts clipped into it when not in use. The spare tyre sat vertically at the very rear of the cargo area under a vinyl cover. The SV-1 had a rear fuel filler similar to the early coupes. Toyota changed all Celicas to side fuel fillers in mid 1972, so from the RA28 all production liftbacks had fuel fillers on the left rear quarter panel with a cover flap. The RA25 and TA27 were the first production liftbacks and their fuel fillers were in the centre rear of the vehicle, behind a pulled down panel. The SV-1 rear hatch glass was a bit larger than the production version. The key hole for the hatch was on the beaver panel (it was on the hatch on production liftbacks). The grill was an ST type – just like all 1973–1975 production liftbacks (even the GT models). Dual exhaust tips exited out the rear (production Celicas had a single exhaust tip). An electric aerial was put in the left rear quarter (the TA22 had this on the left front wheel guard). The RV-1 (a prototype 2 door wagon ba

Marinetta (1971)

The Marinetta 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 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.

RV–1 (1971)

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.

MH20 (1972)

The Toyota MH20 is a concept car introduced in 1972, at the 19th Tokyo Motor Show. It is a motor home, based on a small bus.
