Defending world champions Mercedes was used their all seven remaining in-season upgrading engine tokens ahead of the Italian GP and the race winner Lewis Hamilton shows unbeatable pace with upgraded power unit.
But, Rosberg had some troubles with his upgraded engine during FP3 on the Saturday morning and Mercedes decided to switch back to an older specification engine.
On the race day, German’s engine caught fire during the closing stages, forcing Rosberg to retire as Mercedes teammate Hamilton secure the victory to extend his title lead.
But, Nico declines to believe it is inevitable the Briton will retain the title.
“I approach the final seven races with the attitude that there’s nothing to lose. It’s maximum attack and I won’t be giving up the fight, no way,” Rosberg told DPA.
Germany’s Auto Motor Und Sport confirms that Rosberg will drive the “new Mercedes V6 Turb, which was changed in Monza after third practice” adding that the “a ruptured heat exchanger had caused the contamination of the oil”.
Hamilton is targeting a third world title and breathed a huge sigh of relief at Monza last time out when a stewards’ inquiry into incorrect Mercedes tyre pressures decided no action was necessary. His confidence is therefore high for this weekend
“It won’t be easy to make it three – far from it. But I’m riding high right now and I’ll be pushing for that hat-trick,” Hamilton told DPA.
After the Italian GP DNF, Rosberg has slipped to 53 points behind his Mercedes teammate and championship leader, Lewis Hamilton.
