The fight for fuel-efficient cars is still going on. Toyota already experimented with them in the seventies.

After 46 years, Toyota returned the Toyota Aluminum Body Experimental Vehicle study from 1977 to the Tokyo Motor Show. There are several reasons. On the one hand, it is an interesting diversification of the exhibition area, but above all, the idea of ​​this car is still relevant.

As Toyota’s press release states, the Japanese were looking for a solution to more responsible management of natural resources four decades ago. In short, they wanted to produce the most efficient cars with minimal consumption. Toyota has understood that the biggest fuel guzzler is weight. She saw the solution in aluminum bodies, which at the time were the privilege of only sports cars. The Japanese brand wanted to bring them into the world of regular passenger cars.

The two-seater aluminum concept weighs only 450 kg, and it is barely a titular kei car. It measures 3560 mm in length (the limit for kei cars is 3.4 m), is 1492 mm wide and only 1156 mm high. Under the hood, it has a 0.547-liter engine, which is said to consume only 2.9 liters of fuel per 100 km at a constant speed of 60 km/h.

It is clear that in addition to weight, aerodynamics also played a role. That’s probably why the unpainted aluminum concept looks like a shoe and has a long hood that would fit three times the used engine. The sloping rear makes you think of the AMC Gremlin, which was also produced in the 1970s. However, Toyota has taken into account space saving as the side doors slide back when opened like MPV rear wings. As a result, there is no need for a wide parking space.
