Not again! Kiwi Brendon Hartley forced to retire from second straight F1 race after more engine problems

Kiwi Formula 1 driver Brendon Hartley has been forced to finish his race early once again after his car encountered more engine problems during the Brazilian Grand Prix in Sao Paulo this morning.

Hartley was sitting 17th in the race when his crew informed him the car had to be brought in for engine issues - something which has plagued Hartley's team Toro Rosso over the last month.

It is the second consecutive race Hartley has had to retire from due to the fault after his car caught fire two weeks ago in the Mexican Grand Prix.

But the Kiwi showed more signs of his potential, reaching as high as 12th place before exiting on the 41st lap.

Ferrari driver Sebastian Vettel won this morning's race.
