For any vehicle, wind resistance has two sides. It's not that lower is better, and it's not higher that is!
The aircraft requires a small amount of drag when taking off, but a lot of drag when landing, so the aircraft adjusts the wind resistance through the spoiler changes in the wings.
The Shenzhou spacecraft needs small resistance to leave the earth, but it needs a lot of resistance to return to the earth, so the spacecraft is vertically up to the sky and returns with a parachute.
The car needs little drag when accelerating in a straight line, but it needs to increase downforce when cornering at high speeds, so the drag is also adjusted by means of a spoiler.
Nowadays, a lot of electric vehicles are promoting low wind resistance, low wind resistance. It feels as if the lower the drag of the car, the better. Not really! At different speeds, in different corners, different wind resistance is required. And in the automobile world, the car is not against the wind, but uses the wind, and wears the "wind" on the body.
Lotus believes that aerodynamic design is not only about fighting wind resistance, but also about understanding the wind, capturing the wind, controlling the wind, allowing the air flow through the vehicle, and efficiently using the air flow through the interior of the body to improve the aerodynamic performance, so that the wind can be used for excellent performance, like a windbreaker, adding elegance, which is the top aerodynamic design. To this end, Lotus invented a pore design that makes every car a "breathing Lotus".
1] Modeling design to reduce air resistance!
Drawing on the shark biomimetic design, it combs the airflow, reduces wind resistance, and depicts elegant lines to highlight the appearance of a supercar. This design also helps the vehicle to effectively reduce air resistance at high speeds, improve the stability of the vehicle and increase the cruising range.
2] Void design, improve air performance, take away heat!
The Lotus Emeya is the only model in the million-class coupe with a pore design. The pore design of the 4 sets of RACE-AERO aerodynamic air ducts in the whole vehicle. The four Race-Aero airways include the upper and lower airways of the front bumper, the rear bumper and the brake cooling airway. Among them, the front and rear bumper airways can improve aerodynamics, while the brake cooling airways can effectively remove the heat of the brake disc and prevent the thermal decay of the brakes.
3] Active air kit to feel close to the ground to fly.
The Lotus Emeya has the largest active aerodynamics package in its class and the only one in the industry. When activated, the Active Aerodynamics Package achieves a maximum net downforce of 150 kg for ultimate handling and driving stability.
When the active air intake grille (lotus grille) is open, air flows through the grille to help dissipate heat from the drivetrain and battery. In the closed state, the air is directed to the sides of the vehicle.
The active air dam (the only one in its class) reduces the space between the chassis and the road to improve aerodynamics, and offers both low drag and downforce modes. When the speed of the vehicle is 110km h, the air dam will automatically open and be at an angle of 90 with the ground, which can generate a maximum downforce of 76 kg and enhance the stability of the vehicle; When the speed < 70 km/h, the air dam will be automatically retracted.
The active double-layer rear wing (the only one in its class) balances drag and downforce and has three hovering states. At speeds of up to 90 km/h, the rear wing automatically adjusts to changes in speed, providing up to 215 kg of downforce, improving driving pleasure and stability. When the speed exceeds 170 km h or emergency braking is applied, the double-layer rear wing automatically adjusts to a horizontal angle of 27° to generate 215 kg of downforce, ensuring balance in emergency braking.
Active rear diffuser (unique in class) When driving at high speeds, these two diffusers will actively extend to reduce the contact time of airflow between the upper and lower parts of the body, thereby reducing air resistance.
Summary]: The wind resistance should be low when it should be low, and high when it should be high! This is the Lotus Emeya Blossom. Of course, making good use of the wind is only one aspect, it also has a 6D intelligent chassis, 50:50 balanced weight distribution ultra-low centroid, dual-chamber air suspension, rear-wheel active steering, intelligent anti-roll system, CDC continuous damping adjustable shock absorber, intelligent four-wheel drive system, SiC silicon carbide module and so on. These elements add up to make EMEYA an excellent all-electric supercar. With a lap time of 1:35.728, it also surpassed Mercedes-Benz AMG GT R Pro and Ferrari F8 and other supercars with outstanding track strength in one fell swoop, becoming the "fastest mass-produced electric car in Zhejiang" and "the fastest four-door sedan in Zhejiang".
