NIO has pulled the covers off the new ET7 Sedan at its annual NIO Day. NIO claims exceptional range, performance and luxury from this striking sedan, as well as the introduction of Lidar technology — a first in all-electric consumer vehicles — to aid autonomous operation.

Exterior Design

Clearly carrying cues from the ET Preview displayed in 2019, the ET7 is objectively a handsome car. The short, squat front end is muscular and sporty, and its small, narrow headlights and grille-less front end are reminiscent of Hyundai’s 2021 Kona. The deliberate, triangular slots for the additional front lights remind us of the Kia Stinger (no bad thing).

With a large glasshouse profile, NIO designers have kept the side of the vehicle simple yet cohesive. One accentuating crease near the top of the door plays beautifully with light, while a rising ‘power line’ on the lower part of the doors is reminiscent of Audi’s A5 and A7 Sportback models.

The tapering rear roofline and chunky three quarter panel remind us of the Polestar 2, without the squared-off edges. It’s elegant — if a little unexciting — but does well to give the rear presence while masking the bulk of the vehicle.

The rear itself shares design elements the Audi A7 and Tesla Model 3, with what looks to be an integrated retractable spoiler as well as a fixed ducktail lip in the boot (trunk) lid, and plenty of horizontal lines to accentuate dynamism and presence. Plus the (now ubiquitous) LED light bar running the width of the vehicle as seen on vehicles from Polestar to Porsche.

Interior

The interior is a clean combination of Volvo Scandi-minimalism, Tesla austerity and familiar design cues from the NIO family. NIO has made a big deal about "invisible" smart air vents on both front and rear row, frameless windows and soft close doors with flush door handles.

NIO has compared the interior of the ET7 to a second living room, and it appears to be a comfortable space for four adults on a long trip. Standard equipment includes smart air suspension, heating, ventilation and massage functions all round. There is a full length glass roof, a 23 speaker audio system, dual-LCD screen dashboard and NIO’s Nomi; the automotive world’s first in-vehicle digital assistant.

Battery and Drivetrain

The NIO ET7 will initially be offered with two battery options; a 70 kWh with 500km (310 miles) of range, and 100 kWh with 700km (440 miles) range.

NIO plans a version with a solid-state battery packing 150 kWh and a density of 360wh/kg for later in 2022, which the company claims will offer 1,000km (620 miles) of range. While a number of automakers including Toyota have publicly discussed plans to develop solid state batteries and claim many advantages over Tesla’s technology, for now, solid state batteries have inferior cycle life to batteries with liquid electrolytes, such as Tesla’s setup.

NIO has also revealed Power Swap 2.0, it’s battery-as-a-service (BaaS) swap technology. While many — including us to a degree — remain sceptical about the scalability of this battery swap model, many NIO owners and Chinese customers generally are fond of the technology, which allows drivers to either turn up or book in a time to swap their vehicle’s battery pack in a matter of minutes. NIO claims the stations will be able to store 13 battery packs and provide up to 312 battery swaps per day. NIO plans over 500 battery swap stations by the end of 2021. NIO will offer a monthly payment option for this battery swap technology.

The ET7 offers an all wheel drive dual motor setup, with a permanent magnet motor in the front and an induction motor in the rear. It has a peak system output of 480 kW and 850 Nm of torque. NIO quotes a 0 to 100 km/h (62 mph) time of 3.9 seconds.

Autonomy and Vehicle Technology

One hundred million. That’s the number of real-world kilometres driven using Tesla’s Autopilot system, and its the reason Tesla will be so hard to beat when it comes to autonomous driving. During NIO’s presentation of the ET7, the company praised the new NAD (NIO Autonomous Driving) system, with its Lidar, eleven eight-megapixel cameras and crazy powerful — 1,016 Tera Operations Per Second (TOPS) — Nvidia chip, but what they didn’t talk about was software.

Elon Musk has long dismissed Lidar on passenger vehicles as unnecessary, and has even claimed “LiDAR is a fool's errand…anyone relying on LiDAR is doomed.” Tesla has stuck with a system of cameras and radar for the “eyes” of its autopilot system, but Tesla has had vehicles gathering data in the real-world for years now, with its Neural Network processing trillions of data points. In the video by Whole Mars Blog, a Tesla Model 3 successfully navigates from San Francisco to Los Angeles with almost zero human intervention, with just its computing power, and Tesla’s radar and camera system. Seriously impressive.
