📝📝CLA35 試駕👇🏻👇🏻

https://www.opencar.hk/article/detail?kind=car-review-feature&id=1483

上年如果想買部入門級AMG 車款就一定係A35，不過斬尾車未必係每個人杯茶，而剛剛登場、全新嘅CLA 35 相信可以填補呢個缺口，行出嚟乜都唔需要搞，第一個畀人嘅感覺已經跑得又睇得，而63萬左右呢個「低門檻」價錢就可以擁有部AMG 又確實相當吸引。

全名係Mercedes-AMG CLA35 4MATIC Coupe嘅新車，引擎同A35一樣都採用M260 2.0公升直四turbo引擎，最大馬力有306匹，峰值扭力有400Nm，AMG SPEEDSHIFT DCT 7速孖極力子同4MATIC 四驅系統配合之下0-100km/h 加速時間只需要4.9秒。

第一次喺Showroom 見到CLA 35 真身時，啞灰色車身唔覺得有咩吸引之處。不過試車當日換上白色車身再加鋼琴黑包圍，成部車即時唔同晒，尤其是頭冚上面嘅肌肉感完成突顯晒出嚟，所以想買CLA 35嘅準車主不妨可以考慮白色車身。CLA 35 雖然同CLA 250採用同一個外殼，不過前者就有獨家嘅AMG 包圍、尾翼同19吋合金軨（另需加錢）再加上雙出尾喉，一望落去CLA 35感覺已經惡好多、更加似跑車。

車入面嘅設計配備同現時Mercedes 車系大致相同，最搶眼無疑一定係中間兩個10.25吋大嘅中控mon. 同電子錶板，另外仲有全景式天窗、AMG軚盤、64色氣氛燈、泊車鏡頭、MBUX人工智能系統等等。車籠入面例如門板、桶櫈都用咗猄皮材料令感覺更加有型，不過佢又唔係一味得個「型」字，其他位置混合咗鋼琴黑嘅設計，同車外套包圍互相輝映之餘仲令格調提昇不少，畢竟碳纖內飾真係睇到好悶。CLA 35嘅外觀設計，特別係近C柱嘅位置做工非常流線，所以後座頭頂空間唔會充裕，個人認為平時會向上Gel 頭嘅朋友唔建議坐後座，如果唔係坐完車可能會冇晒造型就慘！不過腿部空間就唔同，空間夠晒，以5尺8吋高嘅駕駛坐姿計，前座同膝頭都仲有兩個拳頭嘅空間。

行車表現方面，新車經過AMG 調校，所以避震比標準版嘅CLA 250 硬淨少少，但唔係會坐到唔舒服個種，硬少少嘅避震再加上4 Matic 四驅系統令行車同出彎都相當穩定，點解可以咁穩陣呢？根據廠方嘅資料，呢部車嘅4 Matic 系統扭力分佈最高前後可以去到50:50，令部車喺任何時間都有強勁嘅抓地力。CLA 35 行車模式一共有5種，分別係：Slippery、Individual、Comfort、Sport、Sport+，可以應付唔同情況下嘅行車需要，穩陣啲又得，進取啲亦得。不過值得一提，雖然轉用Sport+ 模式時喉聲比Comfort 模式澎湃，而且高轉縮油仲會有幾下嘅back fire 嘅聲音，但個人認為聽覺上佢依然可以有進步空間，因為講到尾，佢始終都係部AMG 嘛！至於306匹馬力以現今世代車嘅標準嚟講其實唔算得上係十分恐怖嘅數字，但喺香港咁細少嘅地方用感覺就啱啱好，平時要爬頭切線又或者激進少少都可以。如果你搵緊部又型又跑得下嘅房跑車，呢部Mercedes-AMG CLA 35 諗得過，但係記得揀埋AMG Aerodynamics package喎！會型好多㗎！

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.

เปิดตัว Lamborghini Huracan EVO ลัมบอร์กินี่ ฮูราคาน อีโว ในไทย เปิดตัว 22 มีนาคม 2019 นี้

Automobili Lamborghini presents the new Lamborghini Huracán EVO: the next generation V10 super sports car, based on the prowess and performance of the Huracán Performante and incorporating next-generation vehicle dynamic control and aerodynamics.

“Lamborghini is intent on leading the advance to the highest level of super sports car technologies and driving emotion. This is the essence of the new Huracán EVO. It takes the extraordinary abilities of the Huracán Performante and combines state-of-the-art vehicle dynamic control to amplify the everyday Huracán driving experience,” says Stefano Domenicali, Chairman and Chief Executive Officer of Automobili Lamborghini. “The Huracán EVO is the very definition of evolution: it is a step ahead, redefining the segment parameters. It is remarkably easy to drive, while delivering the most responsive, sensory and agile driving experience, in every environment.”

Technological evolution amplifies driving emotion

The Huracán EVO features the 5.2 l naturally-aspirated Lamborghini V10 engine, uprated to produce higher power output and an emotional and powerful sound, with Titanium intake valves and refined lightweight exhaust system. The Huracán EVO outputs 640 hp (470 kW) at 8,000 rpm with 600 Nm of torque delivered at 6,500 rpm. With a dry weight of 1,422 kg the Huracán EVO reaches a weight-to-power ratio of 2.22 kg/hp, accelerates from 0-100 km/h in 2.9 seconds and from 0-200 km/h in 9.0 seconds. Braking from 100 km/h to 0 is achieved in just 31.9 m, with a top speed of more than 325 km/h.

Lamborghini Dinamica Veicolo Integrata (LDVI)

The Huracán EVO features new Lamborghini rear-wheel steering and a torque vectoring system working on the four wheels, while at the heart of the car is the new feature of Lamborghini Dinamica Veicolo Integrata (LDVI): a Central Processing Unit that controls every aspect of the car’s dynamic behaviour, fully integrating all of the car’s dynamic systems and set-up to anticipate the next move and needs of the driver, interpreting this into perfect driving dynamics.

Lamborghini Piattaforma Inerziale (LPI), a comprehensive set of accelerators and gyroscope sensors placed at the car’s center of gravity, has been enhanced to version 2.0. With improved precision, it monitors in real-time the dynamic vehicle attitude regarding lateral, longitudinal and vertical accelerations, as well as roll, pitch and yaw rate. The magneto rheological suspension, upgraded to version 2.0, instantaneously adapts the damping following inputs from the LPI. A new advanced traction control system together with enhanced all-wheel drive and torque vectoring, allows traction to be directed to a single wheel as required.

Enhanced Lamborghini Dynamic Steering (LDS), able to provide higher responsiveness in corners while requiring the lowest steering angles, is now coupled with rear-wheel steering in order to ensure agility at low speed, as well as maximum stability in high-speed cornering and under braking in the most severe conditions.

The unique combination of all these systems is governed by Lamborghini’s LDVI to create a super-agile and responsive car with unparalleled level of control. Processing data in real time, the Huracán EVO recognizes the driver’s intentions through steering wheel, brake and accelerator pedal inputs, engaged gear and the driving modes selected via ANIMA controller: STRADA, SPORT or CORSA.

External conditions are determined through active suspension and all-wheel drive grip estimation function. All of this information is analysed and processed by LDVI, which turns them into precise inputs for the vehicle dynamic system. A ‘feed forward logic’ is implemented via the dynamic controller, which means the car doesn’t just react, but predicts the best driving set-up for the next moment.

In STRADA, the Huracán EVO is agile and capable for driving enjoyment, whereas in SPORT it becomes playful, intuitive and extremely exciting. In CORSA the Huracán EVO is sharp, reactive and exhilarating for the most extreme driving environments, such as racetracks.

เปิดตัว 2019 Mercedes-Benz CLA Class โฉมใหม่ล่าสุด

Las Vegas. The new Mercedes-Benz CLA Coupe is not only the most emotional vehicle in its class, it is also highly intelligent: From MBUX Interior Assist, which recognises operational demands from gestures and equips the interior with intelligence, through augmented reality for navigation and understanding indirect voice commands to the ENERGIZING COACH that provides individual fitness recommendations, the new CLA offers an array of clever solutions. There are also ingenious details when it comes to the aerodynamics and new functions for the Intelligent Drive driving assistance package. The design underlines the coupé character with its stretched form and design elements such as the bonnet with powerdomes or the rear licence plate which has been moved down. As such it does justice to its predecessor’s status as a design icon.

With MBUX, Mercedes-Benz has been revolutionising how to operate a car and communicate with it since the launch of the A-Class. “Now we go to the next level with an intelligent interior assistance system for the compact class. By recognising gestures it facilitates natural operation,” says Ola Källenius, Member of the Board of Management of Daimler AG, responsible for Group Research and Mercedes-Benz Cars Development. “This is not the only new feature by which the CLA offers a great deal of automotive intelligence.”

“With the first CLA we created a totally new segment with a four-door coupé and celebrated a huge success by selling some 750,000 CLA and Shooting Brake,” adds Britta Seeger, Member of the Board of Management of Daimler AG, responsible for Mercedes-Benz Cars Marketing & Sales. “The new edition of the CLA has been developed further in an intelligent way and is even more emotional and sportier than its predecessor. Coupled with new operating systems, it sets new benchmarks for the entire class.”

The new generation of compacts has made a key contribution to the rejuvenation and image change of the Mercedes-Benz brand. The CLA is important for winning and retaining new customers in particular. The CLA Coupé was launched in the USA in 2013, making it the first compact Mercedes‑Benz on the American market. At peak times, more than two thirds of CLA buyers in the USA came from competitors. On average, CLA customers in the USA are around ten years younger than the typical Mercedes‑Benz customer. In Europe, too, CLA customers are among the youngest in the Mercedes portfolio. In 2017, one in two customers in Europe previously drove a competitor's vehicle. Over 75 percent of European customers who previously drove a CLA as a coupé or Shooting Brake chose a Mercedes‑Benz again for their next vehicle. In total, some 750,000 units of the first-generation CLA Coupé and CLA Shooting Brake contributed considerably to the compact car's success.

In its first year, the new CLA will also be available as an Edition 1. In terms of both the exterior and the interior, this limited edition special model has numerous visual accents which underline its exclusivity. The new CLA will be manufactured at the Kecskemét plant (Hungary) and comes onto the market in May 2019.
