The trio of Matthieu Vaxiviere, Jake Dennis and Nicki Thiim won by almost 11 seconds to comfortably secure a first overall victory for the British marque since 2013, when they triumphed at the same venue.
Starting from pole, Vaxiviere led away from the #88 AKKA ASP Team Mercedes-AMG entry of Adam Christodoulou and began to edge ahead at the front of the field. The Frenchman built a lead of around two seconds, but as the first round of pit stops approached Christodoulou trimmed the gap.
That would prove to be significant when Christodoulou handed the #88 Mercedes over to Tristan Vautier. Vaxiviere remained on track longer before stopping and handing over the Vantage to Jake Dennis, but the British driver emerged close behind Vautier.
He did not remain there for long, however. Dennis quickly caught the Mercedes driver and made a decisive move to re-take the lead, displaying a clear pace advantage in terms of pace.
From this point onwards, the Aston never looked to be under serious threat. Dennis quickly built a comfortable gap over Vautier, holding a lead of 12 seconds by the time of the second pit stops. 
Behind them, the #144 Emil Frey Racing Lexus of Norbert Siedler had moved into third position. Stephane Ortelli had run well in the first stint before handing over to Markus Palttala, who elevated the car into third spot by passing the #62 R-Motorsport Aston Martin with a bold move at turn three.
Out in front, the #76 Aston Martin pitted from the lead with a comfortable advantage and emerged from the stops with an even bigger lead. From there Thiim was able to take a calm approach during the final stint, with Raffaele Marciello taking over the #88 Mercedes in a distant second. Behind these two, however, there was plenty of action.
The #114 Lexus held third into the final stint, but there was a charging Dries Vanthoor to contend with. Just as was the case last time out at Monza, the youngster had a fresh set of tyres on the #1 Belgian Audi Club Team WRT machine he shares with Christopher Mies and Alex Riberas.
Vanthoor homed in on Norbert Siedler, who had taken the controls of the #114 Lexus, but was met with a robust defence from the Austrian driver. Despite Vanthoor holding an advantage in pace the #144 held firm to secure a first Blancpain GT Series podium for the Lexus brand, which sparked emotional scenes in the Emil Frey Racing garage.
Out front Thiim remained cool to win by a shade under 11 seconds, with Marciello following him home in a comfortable second spot.
While the destination of Pro class glory always looked assured, this was not the case in the Silver Cup class.
Throughout the first two stints, victory looked to be heading to the #54 Emil Frey Jaguar G3. Having scored a comfortable class pole, the car of Alex Fontana, Adrian Zaugg and Mikael Grenier went on to lead the first two stints, but technical problems cost them dear in the closing hour.
That created an opportunity for the #6 Black Falcon Mercedes-AMG crew to take top spot. Despite facing pressure from the #78 Barwell Motorsport Lamborghini Huracan, the crew of Abdulaziz Al Faisal, Hubert Haupt and Gabriele Piana held firm to take class honours.
The Pro-Am category was more straightforward. After a first-lap incident ended the hopes of the pole-sitting #333 Rinaldi Racing Ferrari 488, the #49 Ram Racing Mercedes-AMG soon assumed control of the class with Darren Burke at the wheel. He remained cool to hand over to Salih Yoluc leading Pro-Am, with the Turkish driver successfully navigating a largely trouble-free stint.
Finally, Euan Hankey took charge of the car with a comfortable advantage and was able to complete a home victory for the Ram squad.
There was a popular home win in the Am Cup class too, with the Garage 59 McLaren 650 S GT3 of Chris Harris, Alexander West and Chris Goodwin triumphing with a healthy advantage.
It had not always looked like being that way, however. Harris spent his stint battling with the #488 Rinaldi Racing Ferrari 488 machine, which ended with the McLaren running second in class.
But, following the first round of pit stops, West was able to take control of the Am Cup category with a comfortable lead. He successfully extended that advantage before handing over to Goodwin, who was untroubled as he took the car to the chequered flag.
The Blancpain GT Series will reach its halfway mark at the next event, with round five of the 2018 campaign taking place at Paul Ricard. The 1-2 June contest will see the Endurance Cup continue with a six-hour race into the night at the high-speed French venue.
Following the disqualification of the #76 Aston Martin from this morning’s qualifying session and the subsequent decision of the team to appeal, all results remain provisional.
DRIVER QUOTES
Jake Dennis, #76 R-Motorsport Aston Martin V12 Vantage: “I looked to my left coming out of the pits and I could see the Mercedes overtaking me. I pushed as hard as I could for a few laps to try and put some pressure on Tristan and the move paid off. We left each other enough space so there was good respect between us. From then on I just wanted to run a clean stint. The car was incredible all weekend. We’ve had a really strong package and my teammates have done an outstanding job.”
Tristan Vautier, #88 AKKA ASP Team Mercedes-AMG: “Jake had incredible pace and, to be honest, I struggled to get into the rhythm. I saw that he was pulling away so I decided to run the stint as well as I could and just try to be solid. I was hoping I could reduce the gap, but that’s the way it goes. We still managed to be strong all weekend and we finished the job, which is satisfying.”
Stephane Ortelli, #114 Emil Frey Racing RC F GT3: “Taking the first podium for Lexus in the Blancpain GT Series feels really good. This is a great achievement for Emil Frey Racing too as we have been improving a lot since the beginning of the season. Norbert did an amazing job by keeping Dries Vanthoor behind during the last stint, while Markus made a great move on the Aston Martin. We are still fighting to catch up and we’re on a very steep learning curve, but a big thank you to Emil Frey Racing today.
Abdulaziz Al Faisal, #6 Black Falcon Mercedes-AMG GT3: “We had a really good start to the race, so after that we just had to focus and keep going. I maintained the position and we did a good job with the pit stops and drivers changes. Compared to qualifying, the car was quite strong. Overall we had a good race and managed to keep the car safe.”
Salih Yoluc, #49 Ram Racing Mercedes-AMG: “I managed to do a few clear laps during my stint, but there were still some challenges with all of the traffic. Beside this, however, it was a good race. Our car was fast and the team did a great job today.”
Chris Harris, #188 Garage 59 McLaren 650 S GT3: “The team really prepared a solid machine for the weekend and the start was mega. We had a good first stint, the car was really strongly balanced, and I could do some overtaking. I think I over-did the tyres a bit, maybe being greedy, but I’m very happy.”
