"The 'A' for the sedan denotes the accommodating trunk and the aggressive styling," said Toyota in a statement on Wednesday.
The Scion iA is aimed at "young people who need a little more practicality, but still want engaging styling and outstanding driving dynamics," Toyota said.
Toyota earlier confirmed that the production version of the Scion iM Concept compact hatchback will roll out at the 2015 New York Auto Show.
"We've been eagerly waiting for this moment and are excited to introduce our new Scions in New York," said Scion Group Vice President Doug Murtha, in a statement.
"Both the iM and the iA are tremendous additions to our lineup and will appeal to young people with different perspectives and needs. These cars represent the evolution of Scion and are kicking off a new wave of momentum for the brand."
Edmunds says: Car shoppers will see the rebirth of Scion in the Big Apple, with two new vehicles that will end a product drought.
