Scion/Toyota 2AZFE

Scion tC is a compact car introduced by Japanese automaker Toyota in 2004 as a concept car under its recently introduced Scion brand name. The Scion tC was designed to appeal to the Generation Y market. They hoped to do so by making standard features numerous and optional features extremely easy to add. The Scion tC is generally considered Toyota's successor to the Celica whose production ended with the 2006 model year (2005 in the United States). The Scion tC uses the chassis of the Avensis which is sold in the European market, and the Camry's 2.4 L 2AZFE I4 engine with VVTi technology. Its low price (base MSRP of US$17,000 for the 2008 model) is a major feature, as well as the pure pricing marketing style that Toyota has adopted. According to Scion, tC stands for "Touring Coupe." The 2AZFE is also the engine platform of the 2nd generation xB release in 2007.
