N Vision 74, the future signed by Hyundai. Here is the dream supercar that wants to rewrite the future of four wheels; like? With its own special engine…
Hyundai NVision 74the alternate future (but always greens…). End of 2022, almost 2023; right now we are in full swing towards the total electrification of means of transport. A process of ecological transition which started years ago and which points to its complete conclusion, at least as regards the countries of the European Union, in 2035. In short, a future of mobility that has already been written and decided; but apparently someone has some slightly alternative ideas…
Hence, an authoritative and authoritative “nonconformist” voice rises from Korea. And so Hyundai presents its new and futuristic project; a vehicle that unites two totally clean power sources to give life to breathtaking performance and at the same time green ed ecological. A real supercars with an aggressive aesthetic and a “charitable” soul. Here is N Vision 74, a laboratory on wheels (rolling lab) one of a kind, which manages to combine the innovative fuel cell hybrid architecture of the same Korean brand ia a bold and iconic design, represents Hyundai’s vision of the medium-long term future.
In a nutshell we are talking about an ambitious project that essentially translates the brand’s vision for the future sustainable and at the same time fun high-performance driving, surpassing (already) the era of battery electric vehicles (BEV) with the first hybrid cell architecture a hydrogen fuel. But let’s find out even more in depth what this N Vision 74 is all about…
N Vision 74, i.e. an alternative hybrid. Indeed, futuristic…
Let’s start from the beginning. Hyundai started developing the so-called rolling labs in 2012 when the RM project (which refers to the Racing Midship configuration with central engine and rear-wheel drive of the N prototype) got underway. Since the beginning of this new challenge and the subsequent evolution of the series of the same name, the RM models have undergone numerous and demanding road tests to test the new technologies developed, observe their effects on performance and improve them for subsequent application on future models No.
Some examples of technologies initially developed on the rolling labs and which were subsequently introduced on production models are e-LSD (electronic-limited slip differential), the 8-speed double clutch DCT transmission in oil bath and advanced high performance technologies such as the Power Electric System, or the EV dual clutch and torque vectoring systems. But what are rolling tabs?

These, in a nutshell, are real laboratories on four wheels through which Hyundai’s N brand has had the opportunity to explore everything that connects new high-performance motorsport technologies to future N models, building a bridge between its vehicles intended for motorsport and those intended for production. Thoroughly tested, these vehicles aim to bring high-performance technologies from the world of motorsport to the everyday streets. And it is from everything that the N Vision 74 is born, and above all its technology…
A challenge to electrification, or rather concrete help
Electrification is no longer a simple option for the Automotive sector, but rather a concrete change destined to remain forever (or at least until necessary); and this also applies to performance, sports and track cars. However, for a full transition, high-performance electric vehicles need to overcome a number of technical hurdles. Here’s how Hyundai tries to give a concrete solution to these obstacles.
In short, the rolling lab N Vision 74, the first rolling lab Hyundai N’s fuel cell hybrid, was primarily developed to overcome the limitations of electric vehicles. To achieve this ambitious goal, during the development phase, the engineers from the Korean company opted for a hybrid structure that used the combination of a battery electric and of a electric system in cells a hydrogen fuel (FCEV extension).
A system, therefore, capable of taking every advantage of battery electric vehicles (i.e. BEVs), as well as FCEVs. We’re talking zero emissions, better air quality while driving and maximum efficiency. Indeed, hydrogen fuel cells offer an efficiency of 50-60% when only electricity is produced and 80-90% when the heat emitted is reused, as well as higher autonomy and shorter refueling times compared to classic BEVs .
This design also, despite using a hybrid hydrogen-electric powertrain, has a different system configuration than other hydrogen fuel cell or battery electric vehicles. Indeed, it introduces an additional step with the high-capacity battery; this improves the peak loads of the batteries, keeping them within an optimal temperature range for constant power delivery. Furthermore, the two different power supplies of N Vision 74 can be used flexibly according to the different driving conditions; so as to truly offer the best of both worlds.
Performance and effectiveness are the keywords
High performance, high resistance and a very fast recharge, that’s what N Vision 74 intends to offer; precisely for this reason the engineers have developed a cooperative control system to allow the two different energy sources to work together in maximum synergy; giving life to a rather particular architecture…

The car’s hydrogen fuel cell stack is mounted up front, with a T-cell battery located just behind the driver to lower the car’s overall height and center of gravity. While EVs’ typically lower center of mass doesn’t fully compensate for the extra weight they carry, this feature offers significant benefits, such as better traction and less body roll, resulting in a more stable ride especially at high speeds. Furthermore, there are also 2.1 kg hydrogen tanks positioned on the rear axle, above two powerful engines capable of generating a total of 500 kW.
In this way the two power systems present here can work separately. In practice, when excessively high performance is not required, the fuel cell powers the car, while when advanced performance is sought, both systems work in combination.
On an aesthetic level, this N Vision 74 is looking for maximum aerodynamics and a design that is as alternative and “aggressive” as possible. This can be seen from the front intake, featuring a distinctive pixel pattern, as well as the side and rear vents. Furthermore, the tail end of the side skirt and the spoiler, this one inspired by motorsports, create a rear downforce that allows for better dynamics for high performance driving, while the aerodynamic design of the wheels balances aerodynamic efficiency and performance.
