With the new ET5, Nio proves once more that it is serious and is a company in constant growth, presenting an electric car that promises 1000 km of autonomy. For the uninitiated, Nio is a Chinese car manufacturer founded in 2014 with headquarters in Shanghai that immediately specialized in the production of zero-emission vehicles (a sort of Chinese Tesla). In 2016 he presented his first model, the EP9, a track-only supercar equipped with a 1300hp powertrain. A peculiarity of this supercar is the presence of a system to release and replace the flat batteries with the charged ones, without having to charge them directly. The first road model of the Nio is instead the ES8, a seven-seater SUV in production since 2018.
Nio ET5: Its rival is the Tesla Model 3
The Nio ET5 is a midsize sedan : it is 4,790mm long, 1,960mm wide, 1,498mm high and has a wheelbase of 2,888mm. Aesthetically, it is a sleek and modern car. The proportions are fastback , so two volumes and a sloping tail ending with a spoiler. This is a similar setting to what looks like its rival, the Tesla Model 3 , and is advantageous in terms of practicality.
The designers have focused on clean surfaces, with an eye to aerodynamic efficiency, and in fact the Nio ET5 boasts a cX coefficient of aerodynamic penetration equal to 0.24 , a very respectable value. To the advantage of greater aerodynamics of the vehicle, we find solutions such as the completely closed grille, the door handles flush with the bodywork and the slightly hinted duckbill rear spoiler. The only air intakes are found on the front, a trapezoidal-shaped lower one and two lateral ones.
Aesthetic side, the headlights in front are very thin, with two LED “blades” that form the luminous signature and act as daytime running lights. The side is characterized by large glass surfaces and a certain cleanliness, without any superabundance of lines , while not lacking in dynamism. The latter is also given by the trend of the pavilion, which descends gently towards the tail. The glossy black central pillar and side skirts also help lighten the view.
In the queue the lights take the stage, which in reality are a single band that wraps around the bodywork. The auxiliary brake light is embedded in the lower part of the rear window. In the lower part there is a hint of a diffuser, which however has a purely aesthetic function. The roof is completely made of glass (total area: 1.28 m 2 ) and makes the passenger compartment very bright , while protecting against 99.9% of UV rays.
Climbing aboard the Nio ET5 it is evident how the stylists have opted for clean and elegant lines , without too many "baroque". The general setting resembles that of the Model 3, although the latter is even more essential. It is a modern and technological cockpit , in which there is no shortage of refinements, see the air vents and speakers (23 with Dolby Atmos playback standard) hidden from view. Unlike the Tesla, in which all the information is shown in the central display, in the Nio we find, positioned behind the three-spoke steering wheel equipped with capacitive controls (in all probability customizable) a 10.2 "digital dashboard.
The control center is the central vertical display made with amoled technology having a diagonal of 12.8 "and a resolution of 1728 × 1888 pixels. Through it, air conditioning, radio and even the eight driving modes are managed. There is also an unprecedented head-up display, called PanoCinema , which projects information onto the windscreen over an area equal to what the driver would have if he consulted a 201-inch screen placed 6 meters in front of him. In the upper central part of the dashboard is a sphere, which contains cameras. These are used to activate the NOMI voice assistant (always connected to the network) through a simple glance.
Extensive use is made of recycled materials for the construction of the passenger compartment. For example, PET from 100 recycled bottles is used for each Nio ET5 . In addition to recycled materials, minerals and natural plant fibers are also used, which according to the company allows to reduce carbon emissions by more than 30% in the production process compared to conventional materials.
Nio ET5: performance and autonomy
The Nio ET5 is powered by two electric motors , located respectively on the front and rear axles. The front motor, which is asynchronous (or induction) develops a power of 150 kW, while the rear one, which is with permanent magnets, develops a power of 210 kW. Since there is a motor per axle, the Nio ET5 has four-wheel drive. The permanent magnet motor is equipped with a SiC (Silicon Carbide) power module which reduces both energy consumption and noise. Total power of 360 kW and peak torque of 700 Nm allow the Nio ET5 to reach 100 km / h in just 4.3 seconds . The braking distance from 100 km / h to 0 is 33.9 meters.
The autonomy varies according to the capacity of the battery pack , which in the case of the Nio ET5 will be available in three different sizes: standard 75 kWh (estimated autonomy greater than 500 km); 100 kWh (autonomy of over 700 km); 150 kWh (autonomy over 1000 km). The latter should be solid state, not lithium ion. The declared autonomy values, very interesting on paper (especially for the version with a capacity of 150 kWh), were obtained with the CLTC homologation cycle, which usually guarantees better results in the WLTP and NEDC cycles.
Nio has developed eight driving modes for the ET5, which affect the delivery of power and the calibration of the steering and suspension. Let's see them in detail:
- Sport + : is the sportiest mode. The 0-100 km / h sprint is covered in 4.3 seconds;
- Comfort : this is the most balanced mode, designed for maximum comfort;
- Eco : it is useful for gaining some kilometers of autonomy;
- Sport : slightly less thrust than the Sport +. In this case the power delivery is less "brutal", and in fact the 0-100 km / h rises to 5.9 seconds;
- Snow : useful for driving on snow;
- Sand : the torque is dynamically distributed to drive on the sand;
- Wet : it is designed for driving on wet surfaces;
- Custom : the driver has the possibility to customize every single parameter to his liking.
Under the bodywork: how the Nio ET5 is made
As you can see from the image below, the battery pack is flat and positioned between the two axes . This benefits from the space on board and the center of gravity, which is thus lower (it is 48.26 cm above the ground). The weight distribution is optimal, being 50:50. Nio promises neutral behavior of the ET5, with no oversteer or understeer. Low center of gravity and wide track (1,685 mm) made it possible to have a coefficient of resistance to overturning equal to 1.7 . This is higher than the minimum required by the NHTSA (National Highway Traffic Safety Administration) to obtain five stars in the homologation phase.
The ultra-high strength steel-aluminum hybrid body is designed in accordance with C-NCAP (Chinese counterpart of Euro NCAP) and Euro NCAP 5 stars standards. The integral cast rear floor has reduced its mass by 30% while increasing the boot space by 11 liters . The torsional stiffness of the Nio ET5 boasts an excellent torsional stiffness quantifiable in 34,000 N · m / degree.
Nio ET5 and autonomous driving
The Nio ET5, as well as the flagship ET7, is also equipped with advanced autonomous driving technology , called NAD (Nio Autonomous Driving). Let us dwell in particular on the Aquila system, consisting of 33 high-performance detection components, including 1 long-distance high-precision lidar, 7 8-megapixel high-definition cameras, 4 cameras dedicated to 360 ° high-sensitivity 3-inch view. megapixel and 1 enhanced driver perception main, 5mm wave radar, 12 ultrasonic sensors, 2 high precision positioning units and V2X vehicle-road coordination. All the information collected is then processed by the Adam software. Nio will update its level 2 autonomous driving system, but only for a fee.
Price and arrival on European markets
The Nio ET5 will be sold in China at a price of 328,000 yuan, corresponding to around 45,500 euros , with the first deliveries to be made starting from September 2022. By subscribing to the BaaS (Battery as a Service) service, which allows quick replacement of the battery, the purchase price of the Nio ET5 drops to 258,000 yuan, or about 35,700 euros. As for the landing in Europe, it will initially arrive in Germany, Norway, Holland, Belgium and Denmark. By 2025, the company will arrive in more than 25 countries. The car will be available in 9 different colors.
