RWD sports sedan launched by Toyota in 1998. In Japan, it was sold under the name Altezza, Outside Japan, it was sold under the name Lexus IS (first generation) as a competitor to the Mercedes-Benz C-Class and BMW 3 Series. The Altezza was intended for the European D-segment market, so it had a sedan body with an emphasis on practicality and comfort, but it also had a short overhang body with excellent turning ability and a four-wheel double wishbone suspension with excellent handling performance at a high cost. In reality, the Altezza was a sports car in the shape of a sedan. The Altezza was also available with the famous 3S-GE engine, which had won numerous victories in F3, WRC, JGTC and Pikes Peak, and Toyota considered its dynamic performance to be on a par with that of a sports car. As a result, the Altezza achieved good results in racing as the base vehicle for racing machines, including a long reign as class champion in the Japanese endurance racing series. The Japanese tuning industry welcomed the Altezza as a sedan that was as close to a sports car as possible, and a wide range of tuning options were developed, including retrofitting turbochargers and engine swaps, and the car gained great support from Japan's racing enthusiasts.
