Chester Kieffer (born 23 July 2006) is a Luxembourgish racing driver who competes in Porsche Supercup and Porsche Carrera Cup Germany for Schumacher CLRT.
Career
Kieffer began karting at age 15 and made his single-seater debut in the 2023 Ultimate Cup Series Challenge Monoplace season finale at Paul Ricard, where he won all three races in the F4 class.[1] Kieffer then contested round three of the 2024 Formula 4 UAE Championship for X GP at the Dubai Autodrome, where his highest result was fifteenth in race one.[2]
Kieffer's main campaign of 2024 was the French F4 Championship, where he received backing from the Winfield Racing School and enjoyed success in the first half of the season.[3] He got his maiden pole position, podium and win in round two at Lédenon and became the first Luxembourger to win an FIA-sanctioned single seater race.[4][5][6] He picked up another podium in race three that weekend, before winning again in the next round at the Circuit de Spa-Francorchamps.[7] After that, Kieffer only mustered three points finishes from the last 12 races – a highest of sixth at the Nürburgring.[8] Despite this, Kieffer managed to hang onto fourth in the drivers' championship with 116 points.[9]
Kieffer also made a cameo in round six of the 2024 F4 British Championship with Xcel Motorsport at Zandvoort, the only international round in the season, and scored four bonus points for overtaking four cars on his way to 19th in race two.[10][11] In late 2024, Kieffer represented Team Luxembourg in the FIA Motorsport Games Formula 4 Cup at Paul Ricard and finished sixth in the main race.[12][13]
Porsche Cup racing
In 2025, Kieffer switched from Formula 4 to one-make Porsche racing and kicked off his season in the Porsche Sprint Challenge Southern Europe with CLRT Schumacher, where he claimed two pole positions at Portimão, a podium at Estoril, won the rookie title and finished third in the main championship.[14][15][16] Kieffer then competed full-time in the Porsche Carrera Cup France for CLRT Schumacher, scoring his only podium in round three at Circuit de Spa-Francorchamps.[17][18] Kieffer consistently finished in the top 10 throughout the season, beating Enzo Joulié to the rookie title and ending the overall championship in sixth.[19][20]
In 2026, Kieffer stayed with Schumacher CLRT to compete in Porsche Carrera Cup Germany and make his Porsche Supercup debut.[21][22] After a podium at Zandvoort,[23] Kieffer achieved his first PCCD win in the penultimate round at the Nürburgring.[24][25][26] In Supercup, Kieffer secured back-to-back second-place finishes at Spa and the Hungaroring, and never finished lower than 10th.[27][28][29] He ended the season fourth in the standings, as the rookies' champion.[30][31]
Personal life
Kieffer is coached by 2022 Porsche Supercup champion and fellow Luxembourger Dylan Pereira.[32]
