If you disregard works teams such as Ferrari and Mercedes, what are the most successful and iconic chassis-engine combinations in Formula 1 history?
Lotus-Ford, McLaren-Honda and Williams-Renault might be among those that first spring to mind, and each of those combinations won four drivers' world championships. Somehow those names just seem to fit together. But what of the only other partnership that has earned four world titles?
Despite sharing that impressive record, Red Bull-Renault probably doesn't register with many fans as a combination that will be fondly recalled in years to come. That standing reflects the disjointed and at times dysfunctional relationship the two parties have experienced over 12 seasons, which will come to an end in Abu Dhabi in November.
