Test Season 5 took place from December 3rd to the 9th across 6 rounds of racing. The first round on Sunday was a Group 3 race staged on the Driving Park Yamagiwa, and here GSN538 entering with Chevrolet in the second race of the day, together with s-shohei_ of Honda and blackbeauty-79 of Renault Sport scored high on the point rankings.

Round 2 was a match on Mount Panorama in Gr.4 machines. Again the 2nd race of the day was the high scoring race, with the top 3 in this race (L-shooter_RB26, blackbeauty-79, and Brond) raking in a good amount of points. But Chevrolet with GSN538 also came in at a respectable 4th place in this race, placing the overall rankings in the order of Chevrolet / GSN538 in the lead, Renault Sport / blackbeauty-79 in 2nd, and Renault Sport / L-shooter_RB26 in third.

Many of the top rankers did not enter the third round on Blue Moon Bay Speedway/Gr.3, but Mercedes-Benz with Nik_Makozi, Porsche with JUN-_-JEEEEN, and Honda with s-shohei_ raised their effective points.

The top rankers were back in force for Round 4, joining the Gr.4 race on Alsace Village to raise their point totals. In the 2nd race of the day, Renault Sport with L-shooter_RB26, Renault Sport with Brond, and Renault Sport with mitosupa77, and Audi with legacy0193 had a direct match against each other, with Renault Sport/L-shooter_RB26 fending off Brond to win the race. L-shooter_RB26 acquired 1971 points, and because GSN538 of Chevrolet had not participated since the 3rd round, this put L-shooter_RB26 at a great advantage in the effective point rankings.

The onslaught of Renault Sport and L-shooter_RB26 continues into Round 5 at the Suzuka Circuit Gr.3 race. Going heads up against Porsche with JUN-_-JEEEEN, Renault Sport with Brond, Honda with s-shohei_ and Mercedes Benz with Nik_Makozi, he holds them all back for an incredible pole to win, gaining 2056points. Now standing at 5956 effective points, there is a considerable gap between L-shooter_RB26 in first place, and JUN-_-JEEEEN with Porsche in second, and Brond with Renault Sport in 3rd.

The final round was a Gr. 4 race on the Lake Maggiore. Here again there was no stopping Renault Sport and L-shooter_RB26. Winning the race against Renault Sport with Brond, Volkswagen with saika159-, and Audi with legacy0193 in the 2nd time slot, Renault Sport and L-shooter_RB26 became the undisputed Series Champion of Test Season 5.
