Philipp Schiemer, president of Mercedes-Benz in Latin America, said the company estimates some 120,000 trucks will be sold in Brazil this year. That was slightly less than the 126,150 units estimated by Fenabrave, the local distributors' association.

The challenges for Mercedes will be returning to profit and boosting exports, which were hampered by an economic downturn in Argentina, Brazil's main client for vehicles, the executive said.

"Exports continue to be the sector's Achilles heel," Schiemer told reporters. "We are optimistic in relation to Brazil's market... It is important that the reform drive continues," he said.

In December, rival German car marker Volkswagen estimated 5% to 10% sales growth in the Brazilian truck market for 2020.
