Aston Martin faces a race against time to have all three of its LMP1 challengers ready for the Le Mans 24 Hours, after new signing Jos Verstappen crashed heavily in testing at Monza on Monday.
The Dutchman, who is the reigning Le Mans Series LMP2 champion, went off the circuit after losing control under braking for the Parabolica, and claimed on his website that the 15G impact had written off the chassis.
"I was not even pushing for a quick lap time," said Verstappen, who was taking part in his first test for the team. "I was 1.4s slower than my fastest time.
"At the Parabolica I braked at exactly at the same point where I had on the previous laps. We can see from the data that there was less than a metre's difference. But the moment I touched the brake pedal, the rear wheels locked and I spun the car.
"Then I hit the barriers at 308km/h and that was it. The impact was almost 15G and the car is written off."
