Alpine has introduced the A110 GT4+, an updated version of its GT4-class race car, featuring mechanical and aerodynamic improvements. The new model is homologated for seven years under SRO Motorsports Group GT4 regulations and is now available for customer racing teams.

The A110 GT4+ made its competitive debut in late 2024, winning its class in a six-hour endurance race at Circuit Paul Ricard. The car builds on Alpine’s experience in GT4 racing since 2018, incorporating upgrades aimed at improving reliability, performance, and cost efficiency.

Evolution of the Alpine A110 GT4

The original A110 GT4 was introduced in 2018, based on Alpine’s road-going A110. Designed and developed by Signatech Automobiles, it quickly became competitive in GT4 racing. One of its most notable achievements came in 2023, when it won the French FFSA GT Championship, marking Alpine’s first national GT4 title.

In 2022, Alpine released the A110 GT4 Evo, featuring improvements to the gearbox, turbo, and engine block. These refinements helped Alpine secure the 2024 GT4 European Series title, further cementing its place among the top GT4 manufacturers.

The A110 GT4+ builds on these developments, as well as its lessons learned with the A110 in rallying, incorporating further mechanical and aerodynamic enhancements for improved endurance racing performance.

Technical Upgrades and Design Changes

The A110 GT4+ introduces several key updates over its predecessor, aimed at improving reliability, performance, and efficiency in endurance racing. The upgrades focus on engine cooling, drivability, aerodynamics, and driver assistance systems, addressing challenges encountered in previous GT4 models.

  • Cooling and Supercharging Enhancements – Components from the Rallye GT+ version improve both power delivery and temperature management, ensuring the engine operates optimally over long stints. A larger front radiator enhances cooling capacity, particularly under extreme racing conditions.
  • Reinforced Gearbox Spacer – The redesigned spacer improves durability and transmission efficiency, addressing previous wear issues under sustained high loads.
  • Carbon Fibre Airbox – A new lightweight airbox optimises airflow to the engine, improving efficiency while reducing weight.
  • Exhaust and Traction Control Refinements – Adjustments to the anti-lag system and traction control provide smoother power delivery and better handling, particularly in low-grip conditions.
  • Altitude Adaptation via P_atmo Sensor – The new sensor automatically adjusts engine settings based on atmospheric pressure changes, preventing power loss at higher elevations without requiring additional ballast.
  • Aerodynamic Adjustments – An openwork carbon fibre rear windscreen enhances airflow for improved stability, while a reinforced front splitter made of natural fibres increases durability against race track debris and minor impacts.
  • Advanced Driver Aids – The car is equipped with an adjustable Bosch Motorsport ABS system, allowing teams to fine-tune braking performance based on track conditions. Additionally, the traction control system offers multiple settings, helping drivers maintain control in varying grip levels.

The car weighs 1,080 kg and is powered by a 1.8-litre turbocharged four-cylinder engine, producing between 350 and 400 bhp, depending on Balance of Performance (BoP) regulations. It features a six-speed sequential gearbox, a limited-slip differential, and Brembo brakes with six-piston front and four-piston rear calipers, ensuring precise stopping power in demanding race conditions.
