The FX-1 was a concept car by Toyota. It was first shown at the 1983 Tokyo Motor Show and also shown at the Geneva Motor Show in March 1984. It was a showcase for new technologies in driver controls, engine, suspension, materials and aerodynamics. Design cues from the FX-1 later ended up on the Toyota Camry XV20, built between 1996 and 2001.

The TAC3 was a 4WD concept car by Toyota, first shown at the 1983 Tokyo Motor Show. The driver sat in a central position, while two passengers sat behind in separate bucket seats. There was no roof but a rear roll bar provided roll over protection. The TAC3 was shown with a small trailer that also held 4 spare tyres on its towing arm. [2] [3]

The AXV (Advanced eXperimental Vehicle) was a concept vehicle by Toyota that was first shown at the October 1985 Tokyo Motor Show. Its goal was for ultra-low fuel consumption, to be under 650 kg in weight and to have the same interior volume as a small sedan. [4]

The body was aerodynamically shaped, with Cd=0.26, while still seating four people. The bonnet, rear suspension arms and wheel rims were made from SMC (Sheet Moulding Compound), the roof was made from resin between steel sheets and the windows were made from polycarbonate resin.

The engine was a 1.1 litre 3 cylinder diesel. It used turbo-charging, direct injection and electronics to keep high performance levels while maintaining low fuel consumption.

The FXV included both 4 wheel steering and 4 wheel drive with Electronic Skid Control.

The mid-mounted 2.0 L engine had both a supercharger and a turbocharger (with a ceramic turbine wheel), pistons made from magnesium fibre-reinforced metal (FRM), a distributor-less ignition system and a resin intake manifold.

The full colour computerised CRT displays had touch screens which could control the suspension, CD player, air conditioning, cellular phone and 8mm video display. Speed was projected onto a head-up display.

The Toyota GTV (Gas Turbine Vehicle) was a concept vehicle by Toyota with a gas turbine engine. It was first shown at the October 1987 Tokyo Motor Show. [7] [8] A very sophisticated concept vehicle, it was based on the Toyota Carina, and was in fact a proof of concept vehicle slated initially for small-scale production.

A measure of Toyota's intent with the vehicle was its allowing journalists from Car Magazine to review the vehicle in 1986. Their view was favourable with regard to the overall performance of the vehicle, although the natural turbine lag of the engine did hurt the overall impression of the review. The CVT automatic gearbox did however endear the vehicle to testers - this gearbox has now become the cornerstone of Toyota automatic gearboxes, and the basis of the Toyota Prius gearbox. The GTV was also reviewed by Popular Science magazine. [9]

The GTV used the Gas Turbine II engine. A one-stage turbine was used to drive the compressor while a second turbine was connected to the drive shaft. The second stage also took the place of the fluid flywheel (torque converter). Unlike the earlier Chrysler Turbine Car, the GTV had a de-coupled gas turbine (i.e. output was by a separate turbine) with a two-stage heat exchanger designed to reduce the exhaust gas temperature. The compressor turbine spun at up to 68,000 rpm while the output turbine spun at up to 65,000 rpm. A regenerator took waste heat and transferred it to the incoming air, increasing efficiency. The engine output was reduced by 10.13 before being mated to the gearbox, giving a maximum power of 148 hp (110 kW) at 5300 rpm and a maximum torque of 245.9 lb⋅ft (333 N⋅m).

Earlier versions of the Gas Turbine engine were shown at the Tokyo Motor Show in 1975 (in the Toyota Century) [10] and 1977 (free standing). [11]

The AXV-II was a concept car built by Toyota that was first shown at the October 1987 Tokyo Motor Show. [8] [12]

The concept has butterfly doors and pivoted up to the front to allow passengers to exit from the car in places that ordinary conventional doors cannot handle. Gas filled struts kept the door in place when open. The doors covered the roof of the car as well as the sides, with the door glass forming part of the roof.[12]

The hatchback was made entirely from glass that included the rear sides of the vehicle in a similar manner to the early Mazda RX-7.[12]

Mechanical components (engine, gearbox, suspension) were the same as those in the Starlet.[12]

The AXV-II went into production as the Toyota Sera in March 1990.

The FXV-II (Future eXperimental Vehicle II) was a concept vehicle by Toyota that was first shown at the October 1987 Tokyo Motor Show. [8] [12]

It had an all alloy, quad cam, 32 valve, EFI, 3.8 litre V8 engine. It is not clear if the engine was a development of the V series engines used in the Century or a prototype of the 1UZ-FE which was later used in the Lexus LS400 (some 1UZ-FE prototypes from about 1987 were the same size). The radiator cooling fans were hydraulically driven under computer control.[12]

At the time, the drive train was Toyota's only 4WD system using a V8. The front/rear split was normally 30/70 but could change up to 50/50. A 4 speed electronically controlled automatic gearbox was used. Electronic Skid Control and Traction Control were included.[12]

The Pegasus (Precision Engineered Geometrically Advanced SUSpension) was a prototype for the new Toyota TEMS suspension used on later Cressidas, Soarers and Supras.[12]

The FXV-II may have included 4 wheel steering.

The interior included GPS navigation and computerised CRT displays.[12]

The EV-30 was a concept two-seat electric vehicle by Toyota that was first shown at the October 1987 Tokyo Motor Show. .[12]

Th body was made from resin and was shown in both open (no roof) and closed (with a roof) forms, although both forms had no doors. The front bumper sloped back and upwards, running into the cabin to form the dashboard. The rear bumper sloped forward and down, running into the cabin to form the side armrests. The construction was lightweight, being designed as a LSV for use inside shopping malls, hospitals and similar environments.

Zinc-bromide batteries of 106 V were used to power an AC induction motor. This gave it a top speed of 43 km/h (27 mph). When driven at 30 km/h (19 mph) it had a range of 165 km (103 mi). The batteries could be charged from a standard Japanese 100 V mains socket.

Lexus SC400 Coupe

The Toyota 4500GT concept debuted at the 1989 Frankfurt Motor Show. It is a 2-door, 2+2 coupe that signalled Toyota's entry into the competitive upper-level luxury coupe class. Although the car's controversial styling was almost universally disliked by the show-goers at the Frankfurt show, its mechanical components were far more relevant, as they carried over much more closely to its production offspring than the styling did.

Toyota claimed the 4500GT was capable of transporting 4 passengers and their luggage comfortably at a speed of 300 km/h (186 mph). To achieve this, the car had to be both efficient, and powerful. The body's unusual shape (dropping snout, flat and abrupt rear end) yielded an extremely low coefficient of drag for the time period of Cd=0.29.

The power plant was quite impressive. A derivative of Toyota's then-new 1UZ-FE V8, the 4500GT boasted an additional 500 cc of displacement over the production unit, twin overhead camshafts per cylinder bank, and 5 valves per cylinder. This high tech masterpiece produced 220 kW (295 bhp) at 6600 rpm and 390 N⋅m (288 lb⋅ft) at 4800 rpm. This alloy V8 was mated with a 6 speed manual transmission, which was mounted at the rear with the differential to even out the front/rear weight balance.

The suspension used double control arms front and rear. The front utilized upper A arms and lower L arms, and the rear used upper L arms and lower A arms for increased camber to promote stability in high speed corners.

No acceleration testing was ever done on the car, but with 220 kW (295 bhp) and a curb weight of 1,450 kg (3,197 lb), the rear-wheel drive 4500GT could be reasonably expected to achieve 0–97 km/h (0–60 mph) in less than 7 seconds.

The 4500GT never made it directly to the showroom; however, it was the predecessor to the third generation Toyota Soarer (also known as the first generation Lexus SC). The Soarer/SC400 utilized a milder production version of the 4500GT's V8, a 4.0 L with 250 hp (186 kW). The styling of the Soarer/SC400 was in the eyes of many much more cohesive and attractive, and it went on to great commercial success on the mechanical backbone of the 4500GT concept.
