Hyundai reveals IONIQ 5 N electrified sports vehicle
16 November 2023
Hyundai revealed its all-new 2025 IONIQ 5 N electrified sports vehicle to North American media at a pre-show event for AutoMobility LA. IONIQ 5 N is the first electrified iteration for the Hyundai N brand, with future electrified N models to follow. IONIQ 5 N will be available at Hyundai dealers in March 2024.
IONIQ 5 N combines the standard IONIQ 5 model’s Electrified-Global Modular Platform (E-GMP) with N motorsport technologies and leverages N expertise from electrified Rolling Labs (e.g., RM20e, RN22e and N Vision 74). These allow Hyundai to maximize its performance capabilities and ensure it meets the three N performance pillars of ‘Corner Rascal,’ ‘Racetrack Capability’ and ‘Everyday Sportscar’.
IONIQ 5 N Corner Rascal capabilities begin with enhancements to the body-in-white (BIW) structure with 42 additional welding points and 6.9 feet of additional structural adhesives. The motor and battery mounting are reinforced, while front and rear subframes are enhanced for lateral rigidity. World Rally Championship-inspired integrated drive axles (IDA) are applied front and rear and reinforced to endure stronger electric motor torque while reducing unsprung mass with 21-inch forged aluminum wheels.
To enhance steering response and feedback, the IONIQ 5 N steering system was strengthened for improved rigidity. The vehicle features a specially-tuned N R-MDPS (Rack-Mounted Motor-Driven Power Steering) system with a quicker steering ratio and enhanced torque feedback logic. These enhancements result in a more direct and communicative steering experience for greater driving confidence and feel.
N Pedal was developed to help address the inherent weight and size of an electric powertrain while achieving the responsive handling characteristics seen in Hyundai’s championship-winning i20 N WRC cars. This intelligent software function, applied to IONIQ 5 N, is designed to provide instant turn-in behavior and enhanced throttle sensitivity.
Drawing on similar technology used in i-Pedal’s regenerative braking system, N Pedal prioritizes fast and exhilarating cornering over absolute energy efficiency. By utilizing decelerating force, aggressive weight transfer is positioned on the front axle, resulting in sharper, more confident corner turn-in.
N Drift Optimizer helps to maintain a desired drift angle by balancing multiple vehicle controls responding to real-time inputs. The integrated Torque Kick Drift function allows the driver to simulate the clutch-kick action of rear-wheel-driven internal combustion vehicles for scenarios where the driver desires more immediate drift initiation. This is a result of sophisticated, high-speed electronic control technology with reactions in milliseconds.
N Torque Distribution provides fully variable front and rear torque distribution that can be adjusted to 11 levels by the driver. The e-LSD (electronic limited-slip differential) at the rear axle optimizes cornering performance and control. Additional wheel sensors and broader damping ranges with increased damper size broadens the overall tuning envelope of the electronically-controlled suspension, ranging from Everyday Sportscar through full Racetrack Capability, two pillars of N performance.
This powerful EV benefits from several technical improvements. Its electric motors spin up to 21,000 RPM, providing an estimated 641 horsepower (478 kW) with N Grin Boost engaged. This is a result of the two-stage inverter with increased energy efficiency for stronger power output from a new 84 kWh battery.
Several exclusive features aid in track performance. N Grin Boost maximizes acceleration with extra power for a 10-second interval. N Launch Control automatically activates N Grin Boost during launch and provides three different traction levels for the fastest possible launch, allowing drivers to accelerate their vehicle like a professional race car. Track SOC (state-of-charge) automatically calculates battery consumption every lap.
IONIQ 5 N sets a new benchmark for thermal management in severe racetrack conditions. Compared to its competitors, IONIQ 5 N boasts a higher resistance to heat-induced power degradation—i.e., loss of maximum power due to excessive heat.
The enhanced thermal management system uses increased cooling area and volume, enhanced motor oil cooling and a battery chiller. The performance of the battery thermal management system is also enhanced with the minimized heat transfer route from the battery cells to the cooling channel and the new gap filler with high thermal conductivity.
The independent radiators for the battery and motor maximize IONIQ 5 N resistance to performance degradation both before and during intense track driving. Before driving, the driver can utilize N Battery Pre-conditioning to optimize battery cells to the most power-efficient temperature, choosing between ‘Drag’ mode for a short burst of full power or ‘Track’ mode that optimizes the lowest possible battery temperature for sustained lapping.
The N Race feature further optimizes endurance on the circuit, giving drivers more direct control over energy consumption. N Race applies a motorsport-derived approach to maximizing available resources for the fastest possible laps overall. While this type of setting change would normally require a full team of technicians and equipment, IONIQ 5 N offers it via convenient menu selection.
With N Race, drivers are given the strategic choice to prioritize ‘Endurance’ or ‘Sprint.’ ‘Endurance’ maximizes range on the racetrack. This is achieved by limiting peak power, which results in a slower build-up of temperature. Comparatively, ‘Sprint’ prioritizes power and provides shorter bursts of full energy. This helps drivers accurately manage their energy strategy and creates an ideal performance window to achieve their performance targets.
IONIQ 5 N features N-tuned brakes, which represent Hyundai’s most powerful braking system to date. It features 15.75 in. diameter front rotors with four-piston monobloc calipers and 14.2 in. rear rotors. These brakes are constructed with new lightweight materials and dedicated airflow ducting for improved cooling efficiency.
In addition, the regenerative braking system typically used for enhanced efficiency has been recalibrated with IONIQ 5 N to enhance braking performance. It serves as the primary source of braking force, while the mechanical brakes are used to supplement additional braking force when required, ensuring enhanced endurance on the track and exceptional power regeneration.
To address the harsh braking demands of the Nürburgring Nordschleife, Hyundai designed N Brake Regen, an N-specific regenerative braking system developed specifically for IONIQ 5 N. It offers up to a maximum of 0.6 g of deceleration force through N Brake Regen alone and remains engaged under ABS activation scenarios with a maximum of 0.2 g. The risk of brake fade due to vehicle weight is minimized by maximizing the regenerative braking power strategy, resulting in lower brake force and wear applied to the friction-based mechanical brakes.
The seamless blending between the N Brake Regen and hydraulic brakes creates a smooth transition, imperceptible to the driver. Moreover, performance-oriented left-foot braking allows the brake and accelerator pedal to be applied simultaneously on the track.
Fulfilling the N brand pillar of Everyday Sportscar, IONIQ 5 N delivers an engaging shift feeling and engaged driving through the integrated N e-shift and N Active Sound+. N e-shift provides a sense of control over power delivery and shift feeling. N Active Sound + works collectively to deliver a futuristic electrified sound with ICE-like engine and exhaust sounds for a more engaging experience behind the wheel. Together, they enhance the joy of driving by simulating the power-shift feel, rev-matching downshifts and powertrain notes of an ICE vehicle.
Performance enthusiasts have lamented a lack of feedback behind the wheel of many EVs on the market due to the fundamental nature of electric motor tuning. Hyundai N engineers developed the N e-shift and N Active Sound+ functions to deliver greater driver feedback and more precise driver control of IONIQ 5 N dynamic driving conditions. The unique emphasis on precise power modulation differentiates the N approach to EV sound engagement from other vehicles.
N e-shift simulates the eight-speed dual-clutch transmission (DCT) of internal combustion engine (ICE) N cars. It simulates a gearshift by controlling motor torque output and simulates the power-shift feeling between shifts, including synchronized audible cues. As a result, it provides a more precise, interactive driving experience that feels closer to an ICE experience than other EVs.
N Active Sound+ is paired with N e-shift to enhance the driving experience by creating a more engaging and exciting sensory experience for the driver. It incorporates a 10-speaker system (eight internal, two external) that offers three distinct sound themes. The ‘Ignition’ theme simulates the sound of an internal-combustion 4-cylinder engine, and ‘Evolution’ provides a signature high-performance sound inspired by the RN22e rolling lab prototype, featuring variable volume during cornering with a sense of synchronization with lateral g-forces. The ‘Supersonic’ theme is a unique concept inspired by twin-engine fighter jets.
The objective of N Active Sound+ is to provide drivers with an acoustic reference point to gauge the power utilized and available, especially when quickly gauging cornering speeds lapping a circuit. The driver gains an additional reference point to rapidly changing speeds in an intuitive manner, adding the sensory input of hearing to sight and tactile feel. This capability was developed out of thousands of kilometers of vehicle development and testing at the Nürburgring.
Like the standard IONIQ 5, its N variant is equipped with an external Vehicle-to-Load (V2L) capability when equipped with the V2L accessory adapter. V2L allows the driver to use the stored energy from the high-voltage battery to recharge devices, such as an e-bike, electrical camping equipment or domestic appliances — even when the vehicle is off.
