The Transformation of the Toyota Ist
First Generation (2002 – 2007)
The first generation TOYOTA IST went on sale in May 2002 as a subcompact car with elements of an SUV. The chassis was based on that of the TOYOTA VITZ, but with an enlarged upper body. The body size measured in length, width, and height at 3,855mm, 1,695mm, and 1,530mm respectively, thus making for a larger body than the Vitz and an enlarged interior space and luggage space. Moreover, the rear seats could be separated 6:4 and folded down, allowing for the storage of large cargo with substantial length.
The exterior design incorporated elements of an SUV, like a large front grille and wide fender aluminum arch. Moreover, the B and C pillars were blacked out, and by achieving a design that was uniform all the way to the rear windows, a refined exterior was achieved.
Metal decorative elements were used for the instrument panel center, leading to increased quality and texture in the interior. Moreover, for certain grades, genuine leather steering wheels were utilized. The interior design was simple and modern, thus leading to a sleek look that was not excessively ornate.
The 1,298cc gasoline engine with 87 horsepower and 1,496cc gasoline engine with 105 horsepower were made available. Both utilized regular gasoline.
The transmission available for all vehicles was the 4-speed automatic.
For vehicles carrying the 1,298cc engine with 87 horsepower, the FF was available as the drive system; for vehicles carrying the 1,496cc with 105 horsepower engine, both the FF and 4WD were made available.
Fuel consumption for FF vehicles carrying the 1,298cc engine with 87 horsepower measured at 18.0km/L, and for vehicles carrying the 1,496cc engine with 105 horsepower, it measured at 16.4km/L for the FF and 15.0km/L for the 4WD.
In April 2004, aero parts were installed, and the 1.5S L Edition Aero Sports Package was introduced to the lineup. Compared to the base grade, this grade was equipped with electrically storable door mirrors, front and rear spoilers, and specialized aluminum wheels.
In May 2005, minor changes were made, altering the exterior design. The primary changes involved altering the front grille design for a more powerful look. Moreover, for the 1,298cc engine with 87 horsepower, cleaner gas emission was realized, leading to its certification as a “2010 Fuel Consumption Achieving Vehicle.”
Second Generation (2007 - )
In July 2008, a full model change led to the introduction of the Ist’s second generation model. The exterior’s Keep Concept design was carried over, but greater SUV elements were incorporated into the design. The body size was enlarged to a 3 number body size, measuring in length, width, and height at 3,930mm, 1,725mm, and 1,525mm respectively, and the tire size was increased from 15-inch to 16-inch.
In terms of the interior, with an effort to achieve originality and uniqueness, such elements as floating center clusters were utilized, as well as concentric meters that were designed with a radar motif. Moreover, the space between the front and rear seats was enlarged by 30mm, further improving riding comfort. For the rear seats, sliding and reclining functions were installed, leading to an improvement in usability. Moreover, as the seats could be separated and folded down, more seat arrangements became possible.
SRS side airbags and curtain shield airbags were installed on all vehicles as standard equipment, further enhancing safety.
The engine displacement was increased, and the 1,496cc with 109 horsepower and 1,797cc with 132 horsepower were newly made available. Both ran on regular gasoline. Of these, the 1,496cc/109 horsepower 1NZ-FE engine saw improvements in environmental performance, leading to its certification as a “2010 Fuel Consumption Standards +10% Achieving Vehicle.”
The 4-speed automatic transmission was combined with the 1,797cc engine with 132 horsepower, and the CVT was combined with the 1,496cc with 109 horsepower.
As for the drive system, the FF was made available for the 1,797cc/132 horsepower engine, and both the FF and 4WD were made available for the 1,496cc/109 horsepower engine.
The fuel consumption for the 1,496cc/109 horsepower engine measured at 18.0km/L for the FF and 16.6km/L for the 4WD, and 15.4km/L for the 1,797cc/132 horsepower engine.
In October 2009, the 1,496cc/109 horsepower engine was reevaluated, leading to improved environmental performance and its certification as a “2010 Fuel Consumption +15% Achieving Vehicle.” As such, the fuel consumption improved by 0.6km/L, measuring at 18.6km/L.
In August 2010, minor changes were made, leading to an altered exterior design. The rear and front bumpers were made full-colored, and the rear spoiler was enlarged for a more powerful look. The engine lineup was also reevaluated, and the 1,797cc engine with 132 horsepower was discontinued.
In August 2011, improvements were made primarily to the interior. Silver decorative parts were newly added, and the seat materials were reevaluated for an overall enhancement in quality and texture.
In June 2012, with the aim to improve safety features, three-point seatbelts and headrests were added to the rear center seat. Moreover, to improve vehicle stability, the VSC and TRC were installed as standard equipment.
