Mind you, these two EVs are not the sleekest car money can buy today as that title goes to the Mercedes EQS, which has a remarkable Cd of only 0.20. Still, it’s an impressive feat for the ET7, made possible by developing an active grille shutter and special underbody for optimal airflow. While some countries already allow cameras instead of mirrors, Nio’s electric car has conventional chunky side mirror caps, making the 0.208 drag coefficient even more impressive.

It took a lot of work to bring the Cd down, with Nio saying no fewer than 120 hours were spent in the wind tunnel to perfect the shape of the ET7. More than 800 CFD (computational fluid dynamics) simulation cases were necessary during the last two years to tweak 13 different areas of the electric sedan’s body.

From the inclination angle of the windshield to the wheels, every little detail has been refined to achieve the 0.208 drag coefficient. The end result is quite remarkable when you take into account the roof hosts the LiDAR and cameras, which stick out from the body, thus impacting the vehicle’s aerodynamics. The standard air suspension also helped achieve that number, as did the alloy wheels with a bespoke aero design and the door handles that remain flush with the body.

As a refresher, Nio touts a generous maximum range of 620 miles with the giant 150-kWh solid-state battery pack (available late 2022), although that number is based on the NEDC test cycle. There’s also a 100-kWh battery promising 435 miles and a smaller 70-kWh with enough juice for 311 miles. One major feature we mustn’t neglect is the car’s battery-swapping capabilities, a process that will take less than three and a half minutes.

The ET7 is powered by a dual-motor setup with a combined 644 hp and 627 lb-ft (850 Nm), good for a sprint to 62 mph (100 km/h) in 3.9 seconds, making it one of the quickest-accelerating sedans out there. It’s no Model S Plaid, but it will be fast enough for the vast majority of EV buyers.

The NIO ET7 is the latest all-electric model from the Chinese EV manufacturer. Admittedly, the ET7 is likely to remain in the Chinese market but that’s also the largest automotive market in the world and one that BMW — along with every other German manufacturer — is desperate to become popular in. So the NIO ET7 will become a massive competitor for the BMW i4, even if it won’t be sold in Europe or the U.S.

What makes the NIO ET7 impressive is its range. According to the Chinese manufacturer, the ET7 will boast a range of 621 miles (1,000 km), which is by far and away the longest EV range claim yet. Admittedly, it’s been claimed on the Chinese NEDC cycle, which is even more forgiving than the European WLTP. The latter of which would likely give it a lower range rating. Still, that massive range claim is thanks to a monstrous 150 kWh battery pack, which should provide an incredible amount of range, even if it is short of NIO’s lofty claims.

That top-end model will also come with 644 horsepower and be capable of 0-60 mph in 3.9 seconds. There will obviously, smaller battery models, with shorter ranges and the ET7 will have a suite of models with which to take on Tesla, BMW and Audi.

Another trick NIO has up its sleeve is its “charging”. Rather than traditional charging stations (which NIO vehicles can also use), the brand also offers battery-swap stations, which can swap out a depleted battery for a fully charged one in minutes. Top Gear tested these stations awhile back and drove 800 miles, in a NIO ET6 SUV that boasts less than 300 miles of range, without ever charging once. The battery swaps take less than ten minutes and are incredibly simple. Plus, NIO is adding them into what it calls “NIO Houses”, which also house coffee shops and office spaces, so you can grab a quick coffee while your battery gets swapped.

In China, this will likely become an incredibly popular EV sedan, one that’s cheaper than the equivalent BMW, Tesla or Audi. With its longer range and battery swap ability, the NIO ET7 will be tough to beat. Especially if NIO ever sends its cars west.

Nio has developed the ET7 to accommodate two types of batteries at launch, starting off with a 70-kWh pack offering more than 311 miles (500 kilometers) of range per NEDC. Step up to the larger 100-kWh battery and the range between charges jumps to more than 435 miles (700 kilometers). Towards the end of 2022, an even bigger 150-kWh battery will enable the zero-emissions sedan to travel for more than 620 miles (1,000 kilometers) on a single charge.

At the heart of the Nio ET7 is a dual-motor, all-wheel-drive setup with a combined output of 644 horsepower (480 kilowatts) and an instant torque of 627 pound-feet (850 Newton-meters). The powerful hardware enables the car to reach 62 mph (100 km/h) from a standstill in just 3.9 seconds. The stopping power is provided by Brembo brakes offered as standard equipment.

The ET7 is brimming with advanced technology, including a sophisticated autonomous driving system using no fewer than eleven cameras, 12 ultrasonic sensors, five radars, and more. The interior is also a technological tour de force by combining a fully digital 10.2-inch instrument cluster with a massive 12.8-inch AMOLED touchscreen. Nio has crammed in 23 speakers for the 1,000-watt sound system that comes as standard across the range.

Nio is already taking preorders for its stunning sedan, but the first customer deliveries are not expected to kick off before the first quarter of next year. The company has also disclosed pricing details, with the base model equipped with the 70-kWh battery starting at 448,000 yuan (about $69,200) or 378,000 yuan ($58,300) if you opt for the battery as a service (BaaS), which is essentially a subscription for the battery pack at 980 yuan ($151) a month.

The mid-range ET7 with the 100-kWh costs from 506,000 yuan ($78,100) or 378,000 yuan ($58,300) with BaaS, in which case the owner pays 1,480 yuan ($228) per month. There’s also a fancier ET7 Premier Edition with this battery from 526,000 yuan ($81,200) or 398,000 yuan ($61,500) plus 1,480 yuan ($230) / month with BaaS. All prices exclude any applicable subsidies.

As a final note, it’s important to note the ET7 has been engineered with battery-swapping capabilities and the biggest of the three battery packs is actually a solid-state battery. The company says it takes less than three minutes to complete a battery swap and the whole process is automatic through a dedicated battery swap station of which Nio aims to have 500 operational by the end of this year.
