The Toyota Belta is a Toyota Vitz-based sedan that replaced the Toyota Platz (originally launched by Toyota Motor Corporation in 1999) in Japan and the Toyota Echo sedan (as the Platz is known as) in North America. The redesigned sedan goes on sale in North America starting 2006. Renamed the Toyota Yaris sedan for North America, the Belta arrives for 2006. The Belta is equipped with 1.0 to 1.3 L engines in Japan and a 1.5 L from the Scion xA, xB and the Toyota Echo sedan. The hatchback variant of the Belta and Platz is the Toyota Vitz. In some parts of South East Asia (not including Hong Kong and Japan), a modified version of the Platz sedan with different body panels is sold under the name Toyota Vios.
The Belta and Yaris (2006 generation) comes in a variety of models, much like the outgoing Platz and Echo, but that is all that the two cars have in common. The Vitz hatchback model and the Belta share underpinnings with each other. However, the Vitz was designed at Toyota's European design studios while the Belta was designed at Toyota's Japanese design studios - two completely different design projects for similar cars marketed toward different demographics. The Belta out-proportions the outgoing Platz. While the outgoing Vitz and Platz models look and feel virtually alike (the only things the cars don't share is the front clip, lights, rear doors and bodies from behind the B-pillar), the new Vitz and Belta are much more subtly related. While the dashboards are similar, they are not the same. The cars only share a frame and the drivetrain options. Any sheetmetal is completely different. The doors, again, look similar, but are not the same. And the trim levels for the cars are far from each other. The Vitz goes sport with the RS package, while the Belta goes sportier or more towards luxury with the XS package and the XG package. Where as the Vitz is designed to be a cute car, the Belta is designed as a sedan.
The Canadian version of the Yaris sedan, which is simply called the Yaris, is based on the American Yaris S with power and all-weather guard packages, but with stardard 14 inch wheels. Option packages comes in one of B, C, D, or Aero packages. The B adds 15 in all-season tires, chrome trim on the decklid, front and rear splash guards, colour-keyed door handles, blacked-out side window frames, keyless entry and power door locks; the C adds ABS, air conditioning, power windows, colour-keyed mirrors and power mirrors; the D adds both side and side-curtain airbags; the Aero adds aluminum alloy wheels, wheel locks, a rear spoiler, and a body kit. The D, however, does not have air conditioning or side airbags.
