This showcar drew inspiration from the original NA generation to see the future of Miatas.
The 18-inch magnesium alloy wheels gave it the appearance of being glued to the road. While the rear and front designs were inspired directly by the Miata NA, the large 18-inch wheels looked like it was stuck to the road. The engineers moved the engine 15.7 inches (400mm) to the rear, and 1.6 inches (41mm) lower than the roadster. Mazda placed the air conditioning unit behind and ahead of the rear axle to provide extra space for the engine.
The heart of the Ibuki was a 1.6-liter four-cylinder gasoline engine. It had direct injection and sequential timing. The engine was combined with an electric motor which, in addition to boosting acceleration and controlling the engine vibrations, also worked well. Mazda was able to install a lighter flywheel which improved the response.
The concept also had a shorter-throw gearbox, which was lighter than the Miata NB’s. It was designed to replicate the feel of the first generation. The keyless entry and LED headlights were a novelty at the time. The audio system was another interesting feature, as the speakers and ducts for the air conditioning were combined in one unit.
To keep weight down, the body panels were made of reinforced plastic. This was combined with aluminum inner panels, carbon fiber engine frame, and propeller shaft. The trunk is unique because it has a side-opening mechanism that allows for easier loading and unloading of cargo.
Mazda created the Ibuki as a concept car. However, some of its design characteristics can be seen in Miata NC two years later.
