It was announced on Thursday that IndyCar will postpone its plans to debut the hybrid technology – paired with its current 2.2-litre twin turbocharged V6 engine – from the season-opening Grand Prix of St. Petersburg on 10 March until after the Indy 500 on 26 May.
In total 13 drivers representing four teams – Andretti Global, Arrow McLaren, Chip Ganassi Racing and Team Penske – have combined for over 15,000 miles in testing over the last three months.
