Hyundai Engine Builder Swindon Powertrain Exits BTCC Grid for 2027 Season

A prominent engine provider in the British Touring Car Championship (BTCC) is set to conclude its continuous 17-year participation in the series starting from the 2027 season. Swindon Powertrain, which has been instrumental in powering championship-winning Hyundai vehicles for Excelr8 Motorsport and Restart Racing, will not see its contract extended. This development follows a period where performance adjustments to engines impacted the Hyundai units, leading to a strategic shift by teams towards alternative powerplants.
Swindon Powertrain's journey with Excelr8 Motorsport began in 2022, supplying bespoke Hyundai engines that quickly propelled Tom Ingram to BTCC titles in both 2022 and 2025. This success underscored the engineering prowess of Swindon, which also supported Restart Racing from 2025. However, changes introduced by the series' technical team in 2026, specifically a reduction in boost across all engines, disproportionately affected the Hyundai units, necessitating further power cuts. These adjustments reportedly hampered the straight-line speed of Hyundai cars, leading to noticeable performance struggles during the 2026 season.
The impact of these performance changes became evident when Tom Chilton, Ingram's teammate, opted to switch to the customer M-Sport-built TOCA engine for the final two races of the season at Silverstone and Brands Hatch. This move signals a likely trend, with expectations that all Hyundai entries will adopt the TOCA engine unit for the upcoming season, further cementing Swindon's departure from its current role.
Beyond its recent work with Hyundai, Swindon Powertrain boasts a rich history in the BTCC. From 2010 to 2021, the company served as the sole supplier for the TOCA engine, contributing to Ashley Sutton's championship victories in 2020 and 2021 with the Laser Tools Racing/BMR Infiniti Q50. This long-standing involvement highlights Swindon's significant contribution to the championship, having powered four BTCC champions in the last seven years alone. The company's legacy also extends back to the 1990s Super Touring era, where it provided engines for the factory Vauxhall team, including John Cleland's championship win in 1995.
Raphael Caille, CEO of Swindon Powertrain, expressed immense pride in the company's achievements, acknowledging the team's contribution to the BTCC's competitive landscape. He emphasized the engines' performance, reliability, and cost-efficiency as key factors enabling numerous drivers and teams to contend for titles. Caille also noted the ever-evolving nature of motorsport, where regulatory changes and commercial considerations inevitably influence technical directions and supplier choices. Despite its anticipated exit from BTCC engine supply, Swindon Powertrain remains actively involved in other touring car series, notably building engines for Toyota in Australia's Supercars series, where the manufacturer has already secured multiple race victories in its inaugural season.
The company maintains an open stance regarding potential future collaborations within the BTCC under a new engine supply initiative. Caille stated that Swindon has gained substantial experience and introduced numerous innovations to the championship, affirming their readiness to achieve further success with the appropriate partner. This indicates that while their current chapter with Hyundai concludes, Swindon Powertrain remains a formidable entity in motorsport engineering, poised for new challenges and partnerships.
In conclusion, the impending withdrawal of Swindon Powertrain from its role as a Hyundai engine supplier in the BTCC marks a significant shift for the championship. With a legacy of powering multiple title winners and a deep history dating back to the Super Touring era, Swindon's impact on the BTCC has been substantial. The move, influenced by technical regulations and team strategic decisions, underscores the dynamic nature of motorsport. While this chapter closes, Swindon's continued engagement in other racing series suggests a future filled with new innovations and competitive endeavors, leaving the door open for a potential return to the BTCC in a different capacity.
