ROME – Raising the bar higher to achieve bigger goals. At Hyundai this seems to be the saying, especially when it comes to electric, motorsport, rolling lab. But what is the end? Imagine a laboratory on wheels where you can test the limits of future technology for production vehicles. Hyundai engineers have developed a hybrid hydrogen architecture that combines a battery electric motor with an FCEV system in the all-new N Vision 74 model.
The first goal was to build a power train that provides high endurance and fast charging on the track. Hence the creation of a system to allow two different sources of energy to work together in high harmony. “The vehicle’s hydrogen fuel cell stack is placed in front, and the T-cell battery is behind the driver to lower the vehicle’s height and center of gravity,” Hyundai explains. “2.1 kg hydrogen tanks mounted on the rear axle, above two powerful motors – one to power each rear wheel – producing a total of 500 kW.”
Battery and hydrogen cell power systems can work differently. When you don’t need impressive performance, the fuel cell powers the car, while when you want high performance both systems work together. For their part, the hydrogen tanks can be refueled in less than five minutes and can be used to charge the battery while the car is running, while its battery-electric power system ensures that the car continues to work perfectly even if hydrogen is not available.
But that’s not all. In terms of cooling, “the car achieves better airflow efficiency under extreme driving conditions, providing the perfect balance to provide maximum performance on the track without overheating,” Hyundai engineers explain. “The placement of fuel cells, batteries, motors and other components has been optimized to make room for three independent cooling channels, the aim of which is to increase energy efficiency in different driving conditions, such as the track.
This is where the shape concept comes in, which is more than icing on the cake: the N Vision 74’s cooling elements are integrated into the aerodynamic design, such as the pixel-patterned front grille and side and side vents. the rear wheels, while the front wheel vents direct lateral airflow into large cooling inlets, to allow temperature control of the electric power system.
Thus, form and function are combined in one large project intended to lead the way of the future on wheels. (fp)
