Hyundai N Vision 74 combines BEV and FCEV technologies for higher performance

Fuel cell electric vehicle (FCEV) technology is not new to Hyundai Motor. In fact, the company was already carrying out R&D on such vehicles, which use hydrogen, from the early 2000s. By 2013, it was able to commercialise a FCEV in the form of the iX35, the first carmaker to do so.

Since then, development on FCEVs has advanced further and the company has accumulated even more experience and feedback through the use of its FCEVs over millions of kilometres in many parts of the world.

Hyundai N, the performance arm, is also looking at FCEV technology for the future and has developed the N Vision 74 as a high-performance hydrogen fuel cell hybrid rolling laboratory. While it is the first such high-performance rolling lab for Hyundai N’s engineers to use, it is not the first time for N where FCEV technology is concerned.

In 2015, the company also created the N 2025 Vision Gran Turismo with the launch of the N brand to envision the future of hydrogen-based high performance. The futuristic N 2025 was conceived to represent Hyundai in the Vision Gran Turismo program, a series of fictional concept cars for the Gran Turismo videogame by Polyphony Digital. While it was never produced as a real-life running model, it had advanced technologies that gave extremely high performance which gamers could experience.

For the N Vision 74, Hyundai’s engineers developed a hybrid structure of a battery-electric vehicle (BEV) in combination with an FCEV system, placed in an all-new layout. By having a fuel cell system and battery-electric system powering the car together, the cooling efficiency is improved.

The two different power sources can be used together or independent, depending on different driving conditions. This fine-tuned logic system enables better torque vectoring by twin motors on the rear, allowing a precise and responsive cornering experience. Moreover, the N Vision 74 explores the balance between the performance and cooling with a 3-channel cooling system.

Measuring 4952 mm long, 1995 mm wide and 1331 mm tall on a 2905 mm wheelbase, the design of the concept car is inspired by the Hyundai Pony Coupe concept of 1974. This concept car developed by the designer Giorgetto Giugiaro was a proposal for a sportscar based on the very significant model in Hyundai Motor’s history. The concept car was then built into prototypes for what was to be Hyundai’s first production sportscar. Although it could not reach production in the end, the daring attitude set the tone for the entire company.

The N Vision 74 inherited the pure surface, dynamic proportioned profile and the unique B-pillar from the Pony Coupe concept. In addition, the lighting units have Parametric Pixel lighting, a feature which is seen on the latest models.

“N Vision 74’s future-oriented design reflects the respect and appreciation we have for the dedication and passion that went into the Pony Coupe concept,” said SangYup Lee, Executive Vice-President and Head of Hyundai Design Centre.

RN22e concept shows how Hyundai N will ensure high performance in fully electric cars

Hyundai will launch its first all-electric high-performance model in 2023. This will be based on the IONIQ 5 and is currently being developed by the carmaker’s N high-performance division. For the development work, the engineers are using two high-performance concept cars — the RN22e and N Vision 74 – as ‘rolling laboratories’.

Hyundai Motor’s ‘rolling labs’ are where it tests and verifies the company’s advanced technologies to apply them to future production models. In this case, a lot of work is being done on electrification and how to provide models with the type of performance the N brand is known for.

Adapt from IONIQ 6
The RN22e, which possesses track-ready performance, uses the Hyundai Motor Group’s E-GMP and a design based on the IONIQ 6 Electric Streamliner. As Hyundai N’s first rolling lab based on the E-GMP, the RN22e shows the N brand’s vision and direction in an electrified future. The concept received its designation because it is the rolling lab of N brand developed in 2022 and is an EV performance.

Testing of the RN22e focusses on the brand’s three performance pillars. These start with ‘corner rascal’, a cornering capability since the brand launch that makes use of e-LSD, Corner Carving Differential for most N models. The RN22e enhances the ‘corner carving’ feel with heavier weighting by exploiting torque vectoring. 3D-printed parts reduce weight and keep the rigidity high for better handling. With AWD, there is optimized torque distribution whatever the drive mode and the driver can customise the amount of torque going to the front and rear wheels.

Enhancing racetrack capability
To enhance the RN22e’s racetrack capability, the N engineers focused on cooling and braking endurance. Track-optimized settings let drivers go to the limit with 4-piston monobloc calipers and 400-mm hybrid discs to ensure plenty of stopping power is available. In addition, the engineers will use the RN22e to study how to deliver dynamic movement with regenerative braking that can precisely controls yaw and corner attack. Once verified, the new state-of-the-art technologies can be transferred to N production models.

Hyundai N Sound+

Sound is also part of the emotional driving experience – but electrified models don’t have the type of sound that excites enthusiasts. So the RN22e has N Sound+ which generates sound from speakers inside and outside the car. In addition, the N e-shift integrates the vibration and shifting feel with N Sound+.
By adapting the IONIQ 6’s streamliner design, the RN22e will leverage on the new EV’s aerodynamic features. In order to maximize the performance, Hyundai N added motorsport-inspired details that add visual dynamism and also improve cooling performance and aerodynamics.
