ชมตัวจริงแบบชัดๆ All-New Nissan Sylphy / Sentra 2019-2020 นิสสัน ซิลฟี่ โฉมใหม่ล่าสุด เปิดตัวในจีน ก่อนเข้าไทย

ในคลิปก่อน เราพาไปชมการเปิดตัว All-new Nissan Sylphy โฉมใหม่ พร้อมรายละเอียดเบื้องต้น ในงาน Shanghai Auto Show 2019 แต่ในคลิปนี้ ทีมออกแบบของ Nissan ทั้ง Alfonso Albaisa และ Ken Lee จะพาไปชม Nissan Sylphy โฉมใหม่อย่างใกล้ชิด ทั้งภายนอกและภายใน รวมถึงการทดลองนั่ง ว่ารถซีดานขนาดเล็กรุ่นนี้ จะให้ความสะดวกสบายในการโดยสาร มากน้อยแค่ไหน

SHANGHAI – The all-new Nissan Sylphy was unveiled today at the 2019 Shanghai Motor Show, sporting a new look and featuring the latest Nissan Intelligent Mobility technologies to give drivers increased connectivity, comfort and confidence.

With a new and more fuel-efficient powertrain, a wider stance, a lower center of gravity, improved aerodynamics and a roomy, luxurious interior, the new Sylphy delivers even better performance and an enhanced driving experience. Seamless connectivity features and a full suite of active safety technologies provide support for drivers.

“The all-new Nissan Sylphy represents the full landing of Nissan Intelligent Mobility in China,” said Daniele Schillaci, executive vice president of Nissan Motor Co., Ltd. “With an even more stylish design and advanced connectivity and safety technologies, the all-new Nissan Sylphy gives customers a whole new level of confidence and excitement, befitting of a leading family sedan.”

At first glance, the all-new Sylphy is characterized by its stance, which reflects the design concepts of “vigor” and “confidence.” The lower profile and streamlined exterior contribute to decreased wind resistance, with a drag coefficient of just 0.26 – equal to that of the Nissan GT-R. Signature Nissan features include the black grille with a three-dimensional V-motion design, bringing about a strong visual impact. The sides are defined by lean, striking proportions that create a sense of motion even when the car is stationary.

These dynamic exterior design cues hint at a number of key performance upgrades. The car is powered by the all-new Nissan HR16DE Gen3 intelligent drive engine with Xtronic transmission. The new powertrain technologies boost engine stability and fuel efficiency1 and provide a linear, smooth driving experience. Steering, suspension and body rigidity have also been enhanced to improve handling and deliver a more solid driving feel.

The wide stance and long wheelbase allow for a spacious cabin where up to five people can ride comfortably in soft, 3D Multilayer ergonomic seats. The interior comes in sporty black, light gray or tan. The tan version features a diamond-cut quilting pattern on the seats that adds a modern, luxurious feel.

Interior features that have been designed for increased comfort and convenience also include the three-outlet air conditioning system. Controlled by a single integrated switch, it supplies air separately to the left and right front seats and to the back seats. An 8-inch center color display and the 7-inch, high-definition thin-film transistor monitor, which shows drive information and readings from the car’s sensors, are arranged inside the meter assembly for a smart, highly functional design.

Among the many Nissan Intelligent Mobility technologies in the all-new Sylphy are seamless smartphone connectivity and intelligent voice command. The Integrated Dynamic Control Module uses targeted brake applications after the vehicle encounters a bump or undulation to immediately improve the level of the body, enhancing ride quality. Additional technologies to assist the driver include Intelligent Trace Control, Intelligent Ride Control and Emergency Brake for Pedal Misapplication.

Safety technologies such as Intelligent Forward Collision Warning, Blind Spot Warning, Lane Departure Warning, Cross Traffic Alert and Intelligent Driving Alert support the driver in anticipating and avoiding hazardous situations.

Over the course of the year, an ultra-sporty BMW M Performance version and an extremely efficient model with plug-in hybrid drive system will be added to the range.

Optimised aerodynamics. Drag coefficient (Cd) reduced from 0.26 to 0.23 (BMW 320d). Progress underpinned by features including active air flap control, Air Curtains and an almost completely sealed underbody.
