This year there are two Toyota Yaris models on the market, but practically the only thing they have in common is their name. One is the 5-door hatchback that's been available for years, and the other is the brand new sedan, which is known as the Scion iA in the U.S. The two models share the same engine, a 1.5-litre 4-cylinder, as well as a 5-speed manual transmission (though the hatchback can be equipped with a 4-speed automatic and the sedan offers a 6-speed automatic).
