劳斯莱斯近日正式发布了新款Dawn敞篷车，该车将在法兰克福车展与公众见面。虽然该车外观设计变化不大，但车身细节部分有80%都是全新的，轮圈高度与车身高度之比为2:1。该车同样采用长引擎盖，短前悬，长后悬和高肩线设计。车头为硕大散热器格栅，向内凹进45毫米，而前保险杠则比Wraith向外延展53毫米。车尾采用优雅的“船尾”造型，车顶板则是“现代手工艺的精品”。车厢内采用的实木装饰可由消费者选择不同的图案和花纹。该车内部采用2+2座椅布局，大量采用实木和真皮装饰，同时提供四温区空调，专属高级音响带有六个独立调校扬声器，镀铬装饰条。该车的软顶在打开和关闭时几乎没有任何声音，整个开启/关闭过程耗时约20秒，不过要在车速50公里以下才可以操控车顶。为了营造更宁静的车内环境，劳斯莱斯工程人员采用所谓的“法式缝合”技术，以确保气流穿过车顶时，内部听不到风噪声。该车动力系统为一台6.6升V12双涡轮增压引擎，功率420千瓦/563马力@5250转/分，扭矩780牛米@1500转/分，车辆百公里加速时间4.9秒，最高时速250公里。
Rolls-Royce Dawn goes official
Rolls-Royce has officially unveiled the new Dawn convertible prior to the car's global premiere at the 2015 Frankfurt Motor Show.
Despite featuring a familiar design, the new luxury cabrio has 80% unique body details with 2:1 wheel height to body height, a long bonnet, short front overhang, a long rear overhang and a high shoulder line. At the front, the massive radiator grille is recessed by around 45 mm whilst the lower front bumper has been extended 53 mm compared to the Wraith.
The rear end of the car is echoing the “elegant design of early ‘boat tail’ Rolls-Royce drophead coupes”. The roof deck is being described as an “amazing work of modern craftsmanship”. The wood for it can be selected by the customers to suit their individual taste with the same pattern being used for different panels in the interior too.
Speaking of the cabin, it features a 2+2 seat configuration and plenty of wooden and leather details. The seats have been designed to help emphasize the “energetic, yet elegant intent and sense of purpose of the car”. Of course, as one would expect of a Rolls-Royce, the machine has all the posh options including a four-zone automatic climate control, Bespoke premium audio system with sixteen individually-tuned speakers, chrome decorative inserts, etc.
The car’s retracting roof is operating in “almost complete silence” in around 20 seconds at speeds of up to 50 km/h (31 mph). The Rolls-Royce engineering team wanted to create the quietest convertible car in the world today and used a “perfectly smooth surface”, combined with the so-called French Seam. These ensure the air flow over the car with the roof up creates no noticeable wind noise.
Power is provided by a 6.6-liter biturbo V12 unit, generating 563 bhp (420 kW) at 5,250rpm and 780 Nm (575 lb-ft) of torque at 1,500rpm. The car uses a dynamic accelerator pedal mapping which delivers up to 30% increased response at medium throttle. 0-100 km/h (0-62 mph) acceleration takes 4.9 seconds, while top speed is limited to 250 km/h (155 mph).
