The Scion tC coupe used to be the affordable brand’s most popular model, accounting for nearly half of Scion’s total sales from 2005 to 2007. In 2006, its highest-volume year, the Scion tC sold some 79,125 units in the United States.

By 2010, sales had dropped to just 15,204 units, and a replacement for the aging “touring Coupe” was launched for the 2011 model year. Though generally well-received by critics, the updated Scion tC failed to sell at anywhere near targeted volumes.

In 2011, Scion sold just 22,433 tCs in the U.S., and that number stayed essentially the same (at 22,666 units) in 2012. Clearly a new model of the tC is needed, and Toyota’s youth-oriented brand will be unveiling such as animal on March 28, at the New York Auto Show.

Aside from the teaser image seen here, neither Scion nor its parent, Toyota, are leaking any further details on the refreshed front-drive coupe. Since the Toyota Camry (which shares the tC’s 2.5-liter four cylinder engine) received a bump in fuel economy for 2012, it’s likely that the new tC will serve up the same.

As for output, if horsepower grows, we don’t expect it will grow substantially from the current tC’s 180 horsepower and 173 pound-feet of torque, unless Scion offers a factory supercharged variant.

We can’t tell much detail on the new tC’s form from the dark overhead view supplied by Scion, but the overall shape doesn’t seem that different from the current model. We’ll let you know the full story next week, as part of our complete 2013 New York Auto Show coverage.
