Hyundai is taking the N brand to the next level with electrification using a number of smart technologies and an approach that doesn’t stray too far from the traditional sports car.
The IONIQ 5 N debuted at the Goodwood Festival of Speed, marking Hyundai N’s first participation at this iconic event. In addition, multiple N vehicles, including the hydrogen-powered N Vision 74 will participate on the iconic hill climb.
In preparation for the Goodwood event, Hyundai was racking at the laps at the challenging Nürburgring racing circuit in Germany.
“The Nürburgring is where every N model is honed to the Nth degree, so our first high-performance, all-electric N model must also prove itself here,” said Till Wartenberg, Vice President and Head of N Brand & Motorsport at Hyundai Motor Company.
“IONIQ 5 N just completed its 10,000km durability test on the Nordschleife, which is an important milestone that proves the vehicle’s high endurance and racetrack capability. And yet, we just began our second 10,000km test to push IONIQ 5 N’s limits.”
For IONIQ 5 N, Hyundai Motor has fused its Electrified-Global Modular Platform (E-GMP) with N’s motorsport-bred technologies and expertise to maximise the EV’s high performance capabilities and ensure it meets N’s three pillars of N performance: Corner Rascal, Racetrack Capability and Everyday Sportscar.
Redefining sound
Many performance enthusiasts have been outspoken about their dissatisfaction with the lack of driver feedback behind the wheel of many EVs. That’s why N engineers developed N Active Sound + and N e-Shift in order to deliver greater driver feedback and therefore more precise driver control of the vehicle’s dynamic handling. N brand’s unique emphasis on precise driver feedback differentiates from past iterations of EV sound.
N Active Sound + consists of a 10-speaker system (eight internal, two external) that provides three different sound themes available for drivers: Ignition, Evolution and Supersonic. Ignition simulates the 2.0 turbo engine of ICE N cars complete with pop and bang sound effects while Evolution is a N signature electronic sound inspired by the N 2025 Vision Gran Turismo Concept and RN22e. Supersonic simulates a fighter jet to give the drivers the sensation of a fighter pilot. All sound options are customisable for drivers to uniquely tailor to their preference.
N e-Shift works closely with N Active Sound + to simulate the eight-speed dual-clutch transmission (DCT) of ICE N cars. N e-Shift simulates a gearshift by controlling motor torque output and simulates the jolt feeling between shifts. The goal is to allow drivers to seamlessly utilise driving techniques honed with ICE cars for a more immersive driving experience that feels closer to ICEs than EVs.
Managing battery temperature
Extracting maximum performance from an EV requires strict discipline on heat management compared to cars with internal combustion engines (ICE) and that requires advanced software implementation. This means each hardware upgrade is further reinforced by advanced software-based performance enhancements.
IONIQ 5 N’s heat management through cooling is given particular care as EVs are more challenging to cool than its ICE predecessors. An enlarged cooling area with N-specific efficient radiator packaging, enhanced motor oil cooler and battery chiller complete the hardware enhancements similar to ICE vehicles. These hardware cooling techniques are further reinforced by new heat management solutions, such as N Battery Preconditioning and N Race.
N Battery Preconditioning pre-sets the temperature of the battery cells to their most power efficient temperature. The battery preconditioning function is split into two modes: ‘Drag’ mode and ‘Track’ mode to accompany different performance driving scenarios. In ‘Drag’ mode, the optimum temperature is set for immediate use of maximum power, while in ‘Track’ mode, the lowest possible battery temperature is optimised for increased number of laps.
N Race gives drivers more direct control on the car’s energy usage, prioritising ‘Sprint’ or ‘Endurance’ driving. ‘Sprint’ is the default state of IONIQ 5 N prioritising full power on demand for the driver. ‘Endurance’ is a setting that maximises IONIQ 5 N’s range on the racetrack. This is achieved by limiting sudden power spikes that slows temperature build-up and increases endurance.
N Battery Preconditioning and N Race are a direct result of N brand’s motorsport-derived approach. This helps drivers to strategise energy consumption in order to maximise performance or longevity. While this type of setting change would normally require a team of mechanics and equipment, IONIQ 5 N offers it at the convenience of a few button presses.
Regenerative braking on the track
Regenerative braking from the motors provide primary braking force with hydraulic brakes providing additional braking force if necessary. Hyundai N engineers designed this unique regenerative braking system especially for IONIQ 5 N, offering up to a maximum of 0.6 G decelerative force – an industry leading figure – through regenerative braking alone. Regenerative braking remains engaged even under ABS activation with a maximum of 0.2 G decelerative force.
IONIQ 5 N’s hydraulic brakes are enhanced with larger 400-mm diameter discs, featuring new lightweight material and optimised airflow for cooling. They reduced dependency on disc brakes increases the longevity compared to ICE vehicles. The seamless blending between the regenerative and hydraulic brakes creates an imperceptible transition to the driver.
