Just when everyone forwarded the ideal ONE price increase, the third wave of official revelations of the ideal L9 also arrived as scheduled. In the first two spoilers, it can be seen that Ideal Car showed the smart cockpit, flagship sound system and flagship seat configuration of the flagship SUV, and this time the spoiler "flagship" is still there, but the label of "full self-development" is more eye-catching.
Key points for speed reading:
1. Self-developed and self-produced 1.5T four-cylinder range extender, fuel consumption of fuel mode heat engine 5.9L/100km;
2. The maximum power of the self-developed front/rear drive motor is 130kW and 200kW, and the acceleration time of zero hundred is 5.3s;
3. Equipped with a 44.5 kWh battery pack, with a fuel tank volume of 65L, it can achieve 1315km endurance (CLTC), and pure electric endurance of 215km (CLTC);

01
Self-developed 1.5T range extender
First of all, the ideal L9 power system, new chassis and domain controller are ideal team's technical self-development, the biggest benefit is that the ideal L9 can better focus on the coordination of software, can improve the efficiency and upgrade range as much as possible. On the contrary, if a new force does not have the scale, process and management of other suppliers, self-research will reduce the development rhythm of car companies.
Ideal L9 as the first product of the ideal X platform, the power system unsurprisingly adopted the route of extended range, which is one of the reasons why ideal cars can rush out of the sky among many new forces, after all, the most comfortable life in 2021 must be Li Xiang.
The Ideal L9 is equipped with a self-developed and self-produced 1.5T four-cylinder range extender, which has a thermal efficiency of 40.5%, and the "hot engine fuel consumption" in fuel mode is 5.9L/100km (CLTC), and the comprehensive fuel consumption will be slightly greater than this value, which is expected to be closer to the Ideal ONE.
However, the L9 has a larger body size, a larger battery pack, and a larger range extender, so the car has made great efforts in body lightweight, air resistance and tire roll resistance, and the application of aluminum alloy material on the chassis diagram is the best proof.
And we also learned from the previous news that the range extender is produced from the "Sichuan Ideal Xinchen Technology Co., Ltd." joint venture between Ideal Automobile and Mianyang Xinchen Power, and the new generation of range extender produced by Ideal Xinchen is a BMW authorized production engine, and the quality of the product has fully reached the quality level of BMW Prince engine.

Zero-hundred acceleration time 5.3s
Judging from the information released, the ideal L9 is also equipped with an intelligent four-wheel drive system, and the maximum power of the self-developed front/rear drive motor is 130kW and 200kW, respectively, so that the maximum power of the L9's drive system is 330kW, the peak torque is 620N·m, and its official 0-100km/h acceleration time is 5.3s (the ideal ONE is 6.5s).
Compared with the peak power of the ideal ONE front drive motor of 100 kW, the peak power of the rear drive motor is 145 kW, which is a significant improvement. And we also got the following horizontal comparison chart from related channels, if only from the perspective of power parameters, the ideal L9 is indeed not inferior to the mainstream of the same size model.
In addition, the Ideal L9 uses a front "five-in-one" powertrain, including a drive motor, generator, dual motor controller and reducer, which is a greater test for the lateral space arrangement of the front cabin, while the dual motor system (red box part) adopts a parallel shaft mechanism, which can be equipped with a more advanced suspension system. In addition, the motor layout is as far forward as possible, reducing the impact of the power system on the interior space.
The rear "three-in-one" powertrain, which includes a rear drive motor, motor controller and reducer, also brings better volumetric efficiency, and the utilization of space in the car will be correspondingly improved.
03
CLTC pure electric endurance 215km
The mileage of the ideal L9 is also exposed at this time, in the previous interior exposure picture, the ideal L9 full oil full power CLTC endurance of 1200km, CLTC pure electric mileage of 200km, is enough to make most users satisfied.
In this official announcement, the ideal L9 is equipped with a 44.5kWh (the ideal ONE is 40.5kWh) battery pack, plus a fuel tank volume of 65L, which can achieve 1315km endurance (CLTC working conditions), of which pure electric endurance is 215km, while the ideal ONE's pure electric endurance is only 188km.
04
Fully developed chassis control system
Chassis part, ideal L9 adopts a fully developed chassis control system, of which the chassis control system includes a number of sub-control systems and functions, such as the familiar car stability control system, active suspension system and steering and other systems are covered.
This allows the chassis control system to play the role of a nerve center, the coordination, information sharing and performance optimization of multiple sub-control systems, and the fully self-developed design can be better managed.
"Ideal L9"
"Ideal ONE"
The ideal L9 has a double wishbone suspension and a five-link structure for the rear suspension. Compared with the ideal ONE front McPherson and rear multi-link suspension structure, the ideal L9 suspension is more advanced, on the one hand, due to the increase in price, so that more research and development costs can be invested, on the other hand, due to the increase in body size, the suspension system also needs to be upgraded accordingly.
05
CDC shock absorber + gas spring
The Ideal L9 comes standard with a CDC continuously adjustable damping damping damper, which automatically adjusts the damping force of the shock absorber in milliseconds according to the vehicle's load, road conditions and the driving state of the car.
Maintain a good body posture for rapid acceleration and emergency braking, and of course, for passengers in the car, while improving driving smoothness and stability, comfort is also guaranteed.
The Ideal L9 is also equipped with a German Viebuck air spring, and the height of the body in different modes is controlled by inflating and deflating, which can not only provide more convenient access to and from the car when parking, loading and unloading luggage, but also automatically reduce the body at high speed to save energy consumption, and the overall handling will be better.
In addition, the gas spring is also different from the ordinary coil spring, which has the non-linear characteristics of variable stiffness, and can ensure better comfort when driving under different road conditions, which is also a more common configuration for high-level models.
06
Fully self-developed central domain controller
The ideal L9 is equipped with a fully self-developed central domain controller, which is more advanced than the current more mainstream functional domain controller, which is equivalent to realizing the deep decoupling between software and hardware, and the calculation and control of the whole vehicle can be covered through the central domain controller, that is, no code rewriting is required, and only a function key is needed to configure, and the iterative upgrade of the whole vehicle can be realized.
The fully self-developed central domain controller can control more components, better linkage of functions, and faster response. It is expected that the ideal L9 will be smoother in the process of automatic parking, including the process of AEB from perception to execution will be further shortened.
The chip is the core computing and integration capabilities that determine the domain controller, which can quickly build products similar to vehicle service gateways and central brains, and the ideal L9 is equipped with NXP's latest S32G vehicle specification chip (architecture below), and the ideal car completes the research and development of all hardware, systems and software.
The chip has 20 CAN interfaces, 4 Gigabit Ethernet interfaces and 2 PCIe 3.0 interfaces, and is also equipped with two network communication accelerators to guarantee a higher speed connection. In terms of security, the chip integrates ASIL D-compliant MCUs and MPU processors, and also provides application processing capabilities.
In addition, the ideal L9 for the extended range of electric systems, air conditioning systems, chassis systems and seat control systems and other functions to achieve full self-development, not only to ensure the scope and timeliness of future OTA, the future will also bring more scenario-based gameplay. It is also clear that the lower energy consumption of the ideal L9 also depends on the upgrading of the control strategy, including the optimization of the range extender and the three-electric system.
In terms of intelligent driving, it has been clear that the ideal L9 will use NVIDIA's orin X chip, and the computing power of a single chip can reach 254TOPS, and it is expected that the ideal L9 will be equipped with two Orin X chips. Desay SV will provide a powerful driving domain controller for the ideal car, and the ideal car will also independently complete all the programming and algorithm logic settings for automatic driving.
