A PEEK under the hood of three new cars from Volvo, Buick and Cadillac will not reveal a Made in China label. But those cars are breaking new ground in the auto industry, becoming the first to be manufactured in the People’s Republic and exported to the United States.

Sweden’s Volvo, now owned by Geely Auto of China, has shipped more than 1,000 copies of its S60 Inscription.

Buick, desperate to fill the most glaring hole in its lineup, the compact crossover, will import the Envision.

And this month, Cadillac announced that it would export a plug-in hybrid version of its new CT6 flagship sedan from China, supplementing production of the standard version from its Detroit-Hamtramck plant.
