General Motors (GM) shares have risen after the firm said it would be more profitable and return more money to shareholders.
Shares in the biggest US carmaker closed 0.6% up after it raised its 2016 earnings forecast by 25 cents to between $5.25 and $5.75 per share.
GM also plans to raise its stock buyback programme by 80% to $9bn and extend it to the end of 2017.
In total, it plans to give $16bn back to shareholders by the end of 2017.
GM executive Mary Barra said: "We made significant progress executing our strategic plan and the results are being demonstrated through our improved earnings."
Ford disappoints
Shares in rival car maker Ford fell more than 3.5% after it said US margins could hit a plateau of 9.5%.
Ford said on Tuesday it would give a special $1bn dividend, and that it expects pre-tax profit of between $10bn and $11bn in 2015.
But this figure was at the lower end of analyst expectations.
"Their guidance is in line or below what was expected," said Matthew Stover of Susquehanna Financial.
