The most indispensable part of the FF91 development team is the former Tesla executives.

The time is not long, "closed door", finally replaced this year's first Internet eco-electric car FF91 turned out, and the new car created by more than 2,000 elite researchers around the world instantly detonated CES (international consumer electronics) The exhibition) created a record of up to 64,124 cars in just 36 hours. In the words of Lu Zhengyu, vice president of LeTV Supercar (China) Co., Ltd.: "This number is the first in luxury car and electric car bookings."

The Gardiner R&D Center is located in an industrial area south of Los Angeles. The grey buildings are not eye-catching, and only the front-facing fish-shaped "FF" sign is the most eye-catching.

It was once the R&D center of Nissan Motors. It was bought by Jia Yueting several years ago. Today, more than 900 R&D personnel from more than 40 countries around the world work here. More than 2,000 people from the other four bases in Munich, Germany, Silicon Valley, Shanghai, and Beijing, China, are working for the development of FF new cars. Silicon Valley is responsible for autonomous driving and artificial intelligence, while major operations such as batteries, inverters, designs, manufacturing and supply chains are carried out in Gardena.

The resume of Nick Sampson, senior vice president of product development and engineering at FF, is related to Tesla. He was responsible for vehicle and chassis engineering under Ellen Muske, and was one of the design leaders for ModelX and ModelS. After leaving Tesla, he became a major R&D executive at Trexa, a technology company focused on electric vehicle chassis. Trexa has developed the first open electric vehicle chassis "GeodrivePlatform" (also known as "variable vehicle platform"). This is reminiscent of the FF91's "VPA Variable Electric Drive Chassis Architecture". The same as the GeodrivePlatform, both have a modular chassis and battery design that can be flexibly matched to the power, anyone can be on their platform. Building a new electric car. NickSampson is also familiar with energy storage, electronics, drive units, applications and controls. He was the first to join FF in the former management of Tesla, in April 2014.

Since then, Tesla's original class has come to the fore: Alan Cherry, vice president of human resources, 23 years of automotive industry experience, and former Tesla senior director of human resources (2008~2012). After working briefly for Picarro for 20 months, he officially joined FF in September 2014.

DagReckhorn and TomWessner, respectively, are vice president of FF manufacturing and vice president of supply chain. They also have Tesla's work experience, and the time to join FF is October and November 2014. On May 17, last year, James Chen, who had worked in Tesla for six years, also announced his departure and joined FF, responsible for domestic and international government affairs and electric vehicle production.

DagReckhorn said: "We (for a few former Tesla colleagues) have known each other for a long time. During the work of Tesla, there was no mistake in research and development. Now, we hope to avoid the mistakes we made in Tesla. The FF plant will be built faster and the FF91 will be mass-produced."

Of course, although FF executives almost all have Tesla's background, they do not fully admit that they are mimicking Tesla to create a new luxury sedan product. The FF91 is seen as a completely different technology and design. Imagination of the new Internet eco electric car.

In the R&D workshop of the FF inverter, a staff member told reporters that the FF inverters are all produced by themselves. "We must ensure that this product is both efficient and reliable, so it must be independently developed and manufactured. It requires high energy. Density and volume should be as small as possible to leave space for passengers. The energy density of this product is 30% higher than that of ordinary products.” At the same time, Tesla uses induction motors, while FF uses permanent Magnetic magnet motor, "Look, there are a lot of windings on our product, which can improve the cross section and reduce the consumption."

In terms of battery design, FF gives a technical route with a battery life of up to 700 kilometers. The battery is not large, but the energy density is 130% of the competitor. It is beyond the Tesla and is rare in the industry.

The company's office responsible for battery technology development is in the middle of the R&D center building. Hundreds of seats are separated by a tight glass door and are not open to the public. One of the staff said: "This high-energy-density battery is highly demanding in terms of R&D and is extremely challenging. One of them is how to keep it for a long life. FF hopes that the battery can last for 15 years or even Longer use time."

In the battery design, the FF91 also inherits the design characteristics of multiple battery packs connected in parallel. Six sets of single cells are compactly placed in the battery module, and the batteries are connected into a safe and compact matrix, which greatly increases the mileage of the vehicle and reduces the excess space. "For us, the stability of the battery temperature is very critical, which is also a big problem in the industry." The battery pack developer told reporters that in the unique cooling design, the coolant continues to circulate throughout the system to achieve rapid heat dissipation. Make sure the cell temperature is the same. The electronic control network monitors the performance of the battery module in real time, balances the temperature, and activates the emergency plan when a component fails. The ballistic-weight, load-bearing aluminum housing maintains a balanced vehicle weight, lowers the center of gravity, and seals the battery pack. The collision zone around the battery pack further protects the battery pack from potential damage.

The FF91 has a facing door for the sensing device. Assuming that there are fire hydrants or other pedestrians around, the FF91 can automatically monitor and close the door in advance to avoid collisions. You can think of it as an enlarged version of a children's toy electric car that automatically avoids when it comes to corners or pedestrians. “The FF91, as a smart electric vehicle, is clearly ahead of the concept car designed by the traditional automobile brand in terms of design concept and technical presentation. This is definitely worthy of recognition.” Li Xiang, founder of the car home, commented on this. .
