Season 4 crowned Jonno in D1, HPJones in D2, JDJT3593 in D3, Darth Ussh in E1 and JPlanteX in E2. Ferrari secured BOTT on 1,648.35 points, 179.4 ahead of VCARB, after 12 rounds of reversals everywhere except E1.
Those totals hide the route. D1 changed leader in China, D2 changed there and changed back at Silverstone-R, D3 passed through a 139-139 tie, and E2 reversed at Baku. E1 alone refused the fashion: Ussh led after all 12 rounds.

Ben and LimitlessDraco3 took first D1 podiums, while Murts converted P4 into a first IMS win.

JPlanteX took the E2 lead 101-78; jak75421's 20.315-second D3 win entered ninth on the margin table; Charlotte and RyeHZ3 added first podiums in E1 and E2. Ferrari's three wins restored it to the top of the round score.
Imola and Canada: records arrive in consecutive rounds

JarvisInitiate's Spanish runner-up score brought D3 to 139-139 with JDJT. VCARB scored 200.5 BOTT points through two wins and seven podiums, seventh in IMS history, and narrowed Ferrari's season lead to 56.8. MAKI took a first E2 victory, while CONNOROCE and piastrigoat applied 30-point and 24-point swings in D2 and D1.
China changed the D1 and D2 leaders together. Jonno overturned a 15-point deficit to lead Websey 133-127; CONNOROCE overturned 11 to lead HPJones 139-125. Tratracer23 beat Ussh by 0.073 seconds in E1, Deathlink10 claimed a first E2 win and winless Ferrari edged VCARB 123.8-122.6 in BOTT.
Silverstone-R and Brazil: one reversal before five final answers
HPJones won Silverstone-R and reversed CONNOROCE's D2 lead, moving from 125-139 to 151-147. FatCat won D1 as Mercedes expanded its constructor advantage to 30; DonutGorilla12 took a first D3 podium from P7. The five driver gaps before Brazil ranged from four points in D2 to 132 in E1.
Brazil produced five different race winners: Jonno, FTR Button, DonutGorilla12, PolyTromp and Webbah87. Jonno's P13-to-P1 recovery completed D1; HPJones' third place secured D2 first; absent JDJT remained first in D3; Ussh closed a wire-to-wire E1 season; JPlanteX finished the E2 reversal 63 clear.
Five constructor champions feed one BOTT winner
Mercedes finished first in D1 constructors, VCARB in D2 and D3, and Ferrari in E1 and E2. Ferrari's cross-division depth kept it ahead of VCARB after every round, then a 219.8-point Brazil score expanded the final BOTT gap to 179.4. Twelve rounds produced repeated reversals among drivers; the team championship's leading name never changed.
