The 37-year-old former Formula One driver from Rotherham, who now competes for Andretti Autosport, was in the closing laps of a race at Pocono Raceway in Pennsylvania on Sunday when a competitor crashed in front of him, hurling debris through the front of his car.
He suffered a severe head injury and had been in a critical condition in hospital since the smash.

Father-of-two Wilson had been fighting for life in hospital since the crash on Sunday.
Jessica Ennis-Hill has completed her golden comeback at the World Championships, winning her first major championship since London 2012 just 13 months after the birth of her son.
It was still unclear just four weeks ago whether the Olympic heptathlon champion would compete in Beijing, having only returned to action in May following the arrival of Reggie last summer.
The Olympic champion led the heptathlon going into today's final three events from nearest challenger and Team GB teammate Katrina Johnson-Thompson.
And after Jess recorded a seasons best of 6 metres 43 in the long jump, Johnson-Thompson fouled three times to end her challenge.
Jess then threw 42 metres 51 in the javelin which meant she went into the final event, the 800 metres, with a six second lead.
But just like in the Olympic stadium three years ago she romped home in first place to regain the title she last won in 2009.

"It is great to be back within a full-time environment and I am looking forward to repaying the faith the club has shown in me," said Mendeika.

"Injuries have set him back a little over the past couple of years but he has a long career ahead and he is certainly looking to make a name for himself here."
