Since 1994, the Detroit auto show has recognized the North American Car/Truck of the Year, with the winners voted upon by a jury of 60 automotive industry journalists from across the US and Canada.
Thanks to the Accord, Honda won awards for three years straight.
The Accord beat the Toyota Camry and the Kia Stinger.
The 2018 Lincoln Navigator won Truck of the Year.

In other news, US energy companies added 10 oil rigs this week, the biggest increase since June. Other factors, including political risk, have also supported crude.
"Honda seems to have executed some sort of magic trick - not only is this 10th-generation Accord far sleeker and more decisively styled than its predecessor, it's somehow roomier inside, too", said Chris Paukert, a NACTOY juror and managing editor of Road Show by CNET. The award caps a positive year for Ford trucks, which saw a 4.3-percent annual pop in segment sales, and a poor term for the Lincoln brand, which saw a 17-percent sales decline. "With its design now aligned with the Continental, the Navigator becomes an even more important image - and the profit-maker for Lincoln".
The wins for the Navigator and the XC60 gave this year's awards a luxury skew. Eligible vehicles, chosen from dozens, must be new or substantially changed. The Volvo XC60 and Honda Civic both took top honors in 2016.
