General Motors has lifted its 2016 profit forecast following strong second-quarter earnings that included a big jump in operating profits in the key North America region.
Net income for the quarter ending 30 June more than doubled to $2.9 billion (€2.62 billion) from $1.1 billion (€1 billion) in the year-ago period.
Revenues jumped 11% to $42.4 billion (€38.35 billion).
"When you deliver cars, trucks and crossovers customers really value, and generate efficiencies across the enterprise, great results follow," said Chief Financial Officer Chuck Stevens.
"With our aggressive vehicle launch cadence and robust global industry sales, we are confident that we can continue to achieve strong financial performance."
The results demonstrated continued strong sales in North America, where cheap fuel and easy access to credit have led to a multi-year auto boom favouring trucks and sport utility vehicles.
Some analysts have predicted US auto sales growth will slow in 2016.
Other highlights included GM's first quarterly operating profit in Europe in five years.
GM also pointed to strong sales in China.
The biggest US carmaker now expects 2016 earnings of $5.50 to $6.00 a share, up from the prior range of $5.25 to $5.75 a share. Earnings in 2015 were $5.02 a share.
Shares of GM jumped 4% in pre-market trade to $32.76.
