The 2025 F1600 Championship Series season was the fourteenth season of the F1600 Championship Series.

Last year's winner was Mateo Naranjo from Team Pelfrey.

The 2025 F1600 Championship saw its tightest title race to date, as Ayrton Cahan narrowly surpassed his brother and teammate, Gabriel Cahan, and only 2 points Wesley Gundler, who clinched a clean sweep of all three races in the last weekend with the determined attempt to erase a 50-point gap.

Meanwhile, David Adorno dominated the F1600 Masters class to claim the season title; his fifth-place finish in the general standings marks the highest rank for a Masters competitor in over ten years. ^{[1] [2]}

Points are awarded to the top twentyfive classified drivers, and the top drivers who enables to achieve the Pole Position or the Fastest Lap during the qualify session are awarded with the corrispective bonus points +3 and +2 points.

The Season Championship will recognize only driver's best 18 of 21 race results including all bonus points earned. ^[19]

Points are awarded using the following system:

Position	1st	2nd	3rd	4th	5th	6th	7th	8th	9th	10th	11th	12th	13th	14th	15th	16th	17th	18th	19th	20th	21st	22nd	23rd	24th	25th+	DNF
Points	50	42	37	34	31	29	27	25	23	21	19	17	15	13	11	10	9	8	7	6	5	4	3	2	1	1

Guest drivers are ineligible to score points.

If a guest driver finishes in first position, the second-placed finisher will receive 50 points. The same goes for every other points scoring position. So if three guest drivers end up placed fourth, fifth and sixth, the seventh-placed finisher will receive thirtyfourth points and so forth - until the twentyeighth-placed finisher receives the final point.
