Sionic history

Sonic 2000, a five-year plan, unified the company with a consistent menu, brand identity, service, and a national purchasing cooperative and advertising program.

As the company employed sixty thousand teenagers, the Sonic carhop was named one of Teen People magazine's "Top 10 Jobs That Rock" in 2001.

The Sonic was originally introduced in 2002 as the Daewoo Kalos and was the first new model after being taken over by General Motors.

In 2003 Sonic celebrated its fiftieth anniversary, and every Oklahoma town with a population of more than four thousand had "America's Drive-In." At the turn of twenty-first century Sonic's new headquarters building was constructed near the Bricktown canal in downtown Oklahoma City.

At the 2007 Frankfurt Motor Show, an updated version of the hatchback was introduced as the Chevy Aveo to be marketed in North America and Europe.

Sionic Advisors is founded in October 2014.

Just one year later, at the 2016 New York International Auto Show, Chevy debuted a facelifted version of the Sonic sedan and hatchback.

In 2018 Inspire Brands acquired Sonic.

With more than thirty-five hundred franchises located in forty-six states in 2020, Sonic is the nation's eleventh-largest chain of drive-in fast-food restaurants.

Sionic Managing Partner Gilly Green won the Leading Individual Advisor award in the Ninth Annual European Wealth Briefing Awards 2021, in which her team were also highly commended alongside a pioneering new initiative from Sionic’s client lifecycle management colleagues.
