It was a one-two punch for General Motors at the opening event of the 2014 Detroit auto show on 13 January, earning top honours in the North American Car and Truck/Utility awards with the Chevrolet Corvette Stingray coupe and Silverado pickup, respectively.

For the second year in a row, both awards went to products from domestic automakers. The 2014 competition marks the first time since 2010 that a single automaker dominated the competition. Incoming General Motors chief executive Mary Barra and product chief Mark Reuss were among those in attendance.

“I’m very pleased and proud of the team,” Barra said amid a scrum of reporters.

Tadge Juechter, chief designer and lead line director for the Corvette Stingray, accepted the award on behalf of Chevrolet. Juechter characterised the win as “an unbelievable exclamation point on top of what has been a fantastic year for us”. The sports coupe defeated the Mazda 3 and the Cadillac CTS.

Despite a recent recall of the pickup truck that affected over 300,000 units already sold, the Silverado beat out the Acura MDX and Jeep Cheroke. This was the second year that the Truck of the Year category was expanded to also include crossover utility vehicles.

The second decade of the competition coincided with the 25th year of the auto show at Cobo Center in downtown Detroit. A panel of nearly 50 jurors selected the finalists from a short list of 12 vehicles in each category.
