大众近日发布了帕萨特蓝驱概念车,该车将在即将开幕的北美车展首次亮相。大众发布这款车旨在向人们展示如何利用非混动技术来提升燃油经济性，这款概念车采用蓝色金属漆车身涂装，改款格栅和后扰流器。车厢内配备双色内饰，真皮座椅，抛光黑色装饰件和碳纤维内饰。该车动力系统为一台1.4升TSI引擎，最大功率112千瓦/150马力，扭矩249牛米。虽然引擎动力并不强劲，但采用了直喷，启停系统和主动气缸管理系统，可以在车辆低速行驶时关闭两个气缸。该车还具备巡航功能，可以在驾驶员松开油门踏板的一瞬间令DSG变速器与引擎断开，从而使机械阻力降至最低。由于上述改进，该车高速路油耗降至5.6升。

 

Volkswagen Passat BlueMotion concept unveiled with cylinder deactivation technology

Volkswagen has unveiled the Passat BlueMotion concept, ahead of its debut at the North American International Auto Show.

 

Designed to show how fuel efficient non-hybrids can be, the concept has a Reef Blue Metallic exterior with a revised grille and a rear spoiler. The car also has a two-tone interior with leather seats, gloss black accents and carbon fiber trim.

 

Motivation is provided by a 1.4-liter TSI engine that produces 150 bhp (112 kW) and 184 lb-ft (249 Nm) of torque. While the engine isn't powerful, it has been equipped with direct injection, a start/stop system and an Active Cylinder Management system that deactivates two cylinders at low speeds. The model also has a coasting function that enables the DSG transmission to decouple from the engine - as soon as the driver releases the accelerator pedal - to minimize mechanical drag.

 

Thanks to all these changes, the Passat BlueMotion concept has an estimated highway fuel economy rating of 42 mpg US (50.4 mpg UK / 5.6 L/100km).
