BMW turned its fortunes around on Sunday after an abysmal Saturday race to finish with six cars in the top eight, as well as locking out the three podium positions.
Marco Wittmann took victory in a chaotic race that was red-flagged at one point due to multiple pit-stop accidents which resulted in three marshals and team members being taken to hospital, one with a "severe leg injury".
The race started with dry conditions but that quickly changed once the lights went out and the showers moved in. Although light to begin with, the rain intensified, forcing drivers to stop for wet weather tyres, which is when things began to go wrong.
Lucas Auer was the first to stop and as he tried to turn into his pit box his Mercedes didn't comply and hit a number of marshals, one of which was pinned between his car and part of the pit building. As the car was pushed back the marshal was seen hobbling into the garage.
Edoardo Mortara was next in and he overshot his box, running into the pit gantry which subsequently fell onto his car, before Bruno Spengler ran into his mechanics, sending a couple of them flying through the air.
A Safety Car was called but as race control realised the extent of what was happening in the pitlane, the red flag was quickly thrown. Meanwhile ambulances began to arrive on the scene, taking three marshals and team members to hospital for non-life threatening injuries.
Once the rain had finally abated, the race was restarted under almost completely dry conditions, with Pascal Wehrlein, Gary Paffett and Daniel Juncadella leading. However with Paffett still on wet tyres, he began to rapidly drop down the field and was almost at the very back when he finally stopped for slicks.
Juncadella took the opportunity to pounce on leader Wehrlein and at Turn 1 got past, but they had yet to stop alongside Nico Muller and Jamie Green. When they did, it was BMW's Philipp Eng who took control of the race ahead of Wittmann, Timo Glock and Joel Eriksson.
That didn't last long as Wittmann was quickly past and remained there until the chequered flag to take victory at the Hungaroring ahead of Glock and Eng, who fought off a challenge by Audi's Mike Rockenfeller.
"That was an unbelievable race and we certainly didn’t expect this result," commented Wittmann after the eventful race.
With Paffett finishing last, Glock was able to reclaim the lead of the championship and now holds an 11-point lead.
