Kimi Räikkönen

... is acclaimed by F1 nerds for winning Grands Prix in three engine eras.

He made his Formula 1 debut in 2001, and won his first Grand Prix in 2003. In those days, V10 engines were used (and had been since 1996).

By the time V8 engines were mandated, in 2006, Räikkönen had won nine Grands Prix. He won none in 2006, but in 2007 he won six and had a total of twelve podium finishes. A dramatic victory in the final race (the Brazilian Grand Prix) won him the drivers' championship by a single point over Lewis Hamilton and Fernando Alonso.

In the next six years (which included a two–year 'sabbatical' from Formula 1) he won only five Grands Prix, and in 2014 the rules were changed to make V6 turbo engines compulsory.

Räikkönen had to wait until the 2018 United States Grand Prix for his first victory in the V6 Turbo era. This set a new record for the longest gap between successive wins in Formula 1 history (113 races).

Lewis Hamilton made his Formula One debut in 2007, and recorded his first four victories that year. He led the drivers' championship going into the final race, but (as we've already seen) was pipped by Räikkönen in the final race. He won the championship for the first time in 2008.

What I don't understand is why V10, V8 and V6 Turbo are referred to as "all three engine specifications in Formula One" (and Kimi Räikkönen is the only driver to win races in all three), when clearly Formula One was going long before 1996 (and Wikipedia lists at least six different sets of engine regulations before that year). No doubt someone will be able to enlighten me.
