Thought I'd compile an alphabet of the most successful drivers beginning with each letter of the alphabet (surnames), some of this might be subjective but I'm going on championships first, then race wins, then placings. Nobody begins with X
Fernando Alonso (could argue for Ascari with also championships but obviously a lot shorter career)
Jack Brabham (Button actually has one more race win but only 1 championship to Brabham's 3)
Jim Clark
Patrick Depailler (surprisingly not that successful a letter - Elio De Angelis tied with 2 wins but Depailler had a lot more podiums)
Vic Elford (8 points in his era is better than Marcus Ericsson's 18 points in the modern era)
Juan Manuel Fangio
Dan Gurney
Lewis Hamilton (the most successful letter. world champs Hawthorn, Hill x 3, Hulme, Hunt and Hakkinen all miss out!)
Jacky Icxx
Alan Jones
Robert Kubica (Kovalainen ties him with 1 win but other results heavily go in Kubica's favour)
Niki Lauda
Nigel Mansell
Lando Norris (before this year it would have been Nannini)
Esteban Ocon (!)
Alain Prost
Dieter Quester (the only Q - he was profiled on the old Rejects site!!)
Nico Rosberg (has most race wins from him, his father, Raikkonen and Rindt who all also have 1 championship)
Michael Schumacher (we have rejects in this list but no Senna!)
Patrick Tambay (another surprisingly unsuccessful letter)
Alberto Uria (who? Had 1 6th place before points were awarded for them!)
Max Verstappen (before he clinched the 4th championship it would have been Vettel)
Mark Webber
Alex Yoong (there was only him and Sakon Yamamoto!)
Ricardo Zonta (again old points systems favour him over Zhou)
