Toyota presented at the 1989 Frankfurt auto show, the 4500GT Concept, a 2 + 2 luxury coupe prototype. The car was equipped with a V8 engine producing 300 hp with 390 Nm of torque, combined with a 6-speed manual transmission. It had a total weight of 1,450 kilos and a top speed of 300 km/h.
The Toyota 4500GT concept had an extremely low drag coefficient of just 0.29 Cd. It had run-flat tires with sensors and an adjustable suspension. These technologies may not be impressive today, but in 1989 they were very innovative.
