Development of the Intelligent Power Unit for the V6 Hybrid Midsize Sedan. <div class="htmlview paragraph">The Intelligent Power Unit (IPU) of the Integrated Motor Assist (IMA) system was developed with the dual objectives of increased output and reduced size. To realize miniaturization and to reduce energy losses, fine patterning of IGBT chips in the inverter was conducted, transfer mold power modules were used, and film capacitors were integrated in the unit. Parts integration by digital control was performed in the 12V DC-DC converter. The internal resistance was reduced and the output increased of the IMA battery by changing the construction of the current collector and increasing the l…

Evolution of Formula 1 Engine. Formula 1 represents the pinnacle of automotive engineering, continuously pushing the boundaries of performance, efficiency, and technological innovation. This paper explores the evolution of Formula 1 engines from the early naturally aspirated and supercharged configurations of the 1950s to the highly advanced turbo-hybrid power units used in the modern era. Key developments such as the Cosworth DFV era, the turbocharged dominance of the 1980s, the V10 and V8 atmospheric engines, and the current V6 hybrid systems with energy recovery technologies are examined in detail. The study also discusses the mechanical principles behind engine operation, turbocharging,…

Hybrid Power Unit Efficiency in Formula 1: Thermal Management, Energy Recovery Strategies, and Performance Optimization. Formula 1 hybrid power units (HPUs) combine highly optimized internal combustion engines (ICEs) with sophisticated electrical energy recovery systems (ERS) to deliver exceptional performance while meeting stringent efficiency and regulatory requirements. This paper explores the thermodynamic performance, waste heat recovery, and energy deployment strategies of modern Formula 1 HPUs, focusing on the integration between the 1.6 L turbocharged V6 ICE and the MGU-H and MGU-K motor-generator units. Drawing from FIA technical regulations, 2022–2024 team specifications, and comp…

Life of a Formula One Power Unit: Valvetrain Systems. <div class="section abstract"><div class="htmlview paragraph">The world of Formula One (F1) is changing with impending 2026 F1 regulations imposing even stricter limits on engine component usage while increasing races. The valvetrain system, specifically the intake valves, is a critical determinant in controlling gas exchange within the cylinders, directly impacting air-fuel charge and power output. The aim of this investigation is to study the mechanisms of intake valve and valve seat wear which will influence engine performance due to leakage path development. The wear mechanism of the intake valves considers wear from impact from valv…

Predicting the Impact of FIA 2026 Power Unit Regulations on the Performance of Formula 1 Car. <div class="section abstract"><div class="htmlview paragraph">This work investigates the impact of the forthcoming 2026 FIA <span class="xref">Formula 1</span> power unit regulations on vehicle track performance. This new regulation introduces a rebalanced power distribution between the internal combustion engine and the Motor Generator Unit-Kinetic (MGU-K), with each unit contributing up to 350 kW. This transition nearly triples the previous 120 kW output of the MGU-K while constraining the internal combustion engine through newly imposed fuel energy limits. A full vehicle powertrain model was dev…

Evaluation of Thermal Performance of the Motor Generator Unit-Kinetic (MGU-K) for 2026 Formula 1 Power Unit Regulations. <div class="section abstract"><div class="htmlview paragraph">The 2026 Formula One (F1) power unit (PU) regulations introduce significant changes, particularly in the Motor Generator Unit-Kinetic (MGU-K), allowing for increased energy recovery under braking and greater energy deployment per lap. These changes are expected to lead to higher heat generation within the electric motor during the energy recovery and deployment phases. This study presents a methodology for assessing the thermal performance of the MGU-K under the 2026 regulations, with a comparative analysis aga…

The Mercedes V6 hybrid Formula One power unit is a series of 1.6-litre, hybrid turbocharged V6 racing engines which features a kinetic energy recovery system (MGU-K) and featured a waste heat recovery unit (MGU-H) until 2025, developed and produced by Mercedes AMG High Performance Powertrains for use in Formula One. The engines were in use since the 2014 season by the Mercedes works team. Over years of development, engine power was increased from 630 kW (840 hp) at 15,000 rpm, to 810 kW (1,080 hp) at 15,000 rpm. Customer engines are supplied to Williams, McLaren, and Alpine. Historically, Mercedes supplied Force India (and its successors Racing Point Force India, Racing Point, and Aston Mar…

The 2026 FIA Formula One World Championship is a motor racing championship for Formula One cars and the 77th running of the Formula One World Championship. It is recognised by the Fédération Internationale de l'Automobile (FIA), the governing body of international motorsport, as the highest class of competition for open-wheel racing cars. The championship is contested over twenty-three Grands Prix held around the world. It began in March and is scheduled to end in December. Drivers and teams compete for the titles of World Drivers' Champion and World Constructors' Champion, respectively. Lando Norris is the reigning World Drivers' Champion, while McLaren-Mercedes are the reigning World Cons…

The Honda RA6xxH/RBPTH hybrid power units are a series of 1.6-litre, hybrid turbocharged V6 racing engines which from 2014 through to present, featured both a kinetic energy recovery (MGU-K) electric motor directly geared to the crankshaft and a heat energy recovery (MGU-H) electric motor attached via a common shaft to the turbocharger assembly. From 2026 onwards, new power unit regulations mandated the removal of the MGU-H electric motor. Developed and produced by Honda Motor Company (and subsequently under their Honda Racing Corporation organisation from 2022) for use in Formula One. The engines have been in use since the 2015 Formula One season, initially run by the then newly re-establi…
