Nico Rosberg was critical of Red Bull rival Daniel Ricciardo after the pair collided during the closing stages of the Hungarian Grand Prix.
Rosberg held second position on the Prime tyres but was being chased by Option-shod Ricciardo during the final few laps.
Ricciardo dived up the inside at Turn 1 but the pair made contact on the exit of the corner, with Rosberg sustaining a puncture.
Rosberg dropped down the order and eventually came home in eighth position, losing more ground to Lewis Hamilton in the title race.
"I had a decent start, if not the best," he said, having initially dropped down to third.
"But I still didn't have a great balance on the option tyre so the Ferraris were pulling away quite quickly at the beginning. It went better on the prime and the race was going well for me until lap 64.
"Racing is very tough sometimes. It's an awful feeling to lose it at the end. For me, the incident with Daniel was pretty clear.
"I was on the ideal line, he braked too late and went wide. I then stayed on the racing line, so it was my corner, but he still had his front wing there and hit me and I got a puncture.
"That destroyed my race, which is a real shame as I could have gained a lot of points on Lewis."
Stewards investigated the collision but deemed it to be a racing incident.
