The Cadillac ATS was chosen as the North American Car of the Year and the Ram 1500 as Truck of the Year at the North American International Auto Show in Detroit this week.
The ATS won over finalists the Ford Fusion and Honda Accord -- the first win for Cadillac in the award's 19-year history.
On the truck side, the Ram beat the Mazda CX-5 and Ford C-Max Energi, a plug-in hybrid crossover. It was the first truck win for Chrysler since 1994, the first year of the awards.
The winners were chosen by 49 veteran journalists who spend a lot of time evaluating each year's new crop of vehicles.
Mark Reuss, head of North American operations for General Motors, called the Cadillac win a "huge boost from a credibility standpoint."
"We out-engineered everybody," Reuss said after the award was announced, adding that the award validates all the hard work by the ATS team.
"A lot of people had written us off, but we went head-to-head with the best."
Juror Michelle Krebs, a senior analyst for Edmunds.com, said the judges appreciated that the ATS was moving into a new segment with the small luxury car.
