[ 资讯] 近日,丰田官方表示,将对全新普拉多柴油版车型进行动力升级,将会搭载2.8T四缸柴油发动机+48V轻混系统,并表示,电气化的升级绝不会影响到车辆的在极端越野环境下的性能表现。据悉,新车将于8月份海外交付。

The drone has completed multiple test flights, China Central Television (CCTV) News reported.
Long Bamboo, a company based in East China's Fujian Province, developed the technique that preserves the bamboo's tough outer layer and allows different parts with different densities of the material to be used according to their properties, improving its overall performance.
In the past, the outer skin of bamboo was often treated as leftover material and eventually burned into low-value bamboo charcoal.
According to a company release in February, bamboo-based composites now make up more than 25 percent of the entire drone, while its fuselage skin is made entirely from the company's own high-performance bamboo composite material.
The bamboo-based material also offers a major cost advantage, costing only about one-quarter to one-tenth as much as aviation-grade carbon fiber. After the drone is retired, the material can naturally degrade, allowing it to effectively "come from nature and return to nature."
The team spent four years building data models, upgrading equipment and refining the material. The resulting drone has a wingspan of more than 2.5 meters but weighs only about 7 kilograms, and has already completed multiple test flights, according to CCTV News.
Bamboo was traditionally used mainly in products such as tableware and furniture. Now, however, the material is finding its way into a wider range of industrial applications. Bamboo fiber is being used in automobile interiors, while bamboo-based materials are also being explored as possible substitutes for plastics, glass fiber and carbon fiber in some applications.
China has the world's largest bamboo resource base, with about 7.56 million hectares of bamboo forests nationwide. The country also ranks among the world leaders in bamboo resources, bamboo cultivation technologies and the development and utilization of bamboo materials, per CCTV News.

。 根据规划,丰田普拉多(参数|询价)的柴油轻混系统与丰田旗下Hilux采用相同的动力总成,将会搭载2.8T涡轮增压四缸柴油发动机并加入48V混动系统;48V电机将可提供16马力与65牛·米的扭矩,可在车辆急加速和发动机启停状态下提供额外的动力,该系统同样拥有动能回收功能,会带来更加顺滑的动力体验,燃油经济状况也将优化,并小幅提升越野性能。 丰田官方表示,MHEV与雅力士、卡罗拉、C-HR和普锐斯等车型使用的HEV混合动力相比,在结构上不需要为电动化装置提供太多空间,这种结构占用的现有平台的空间更少,意味着车身和传动系统都不需要大的修改。同时,该系统也绝不影响普拉多在极端条件和崎岖地形下越野性能表现;此外,电机的安装位置相对“较高”并做了大量的防水处理,这样可以让新车依旧拥有700毫米的涉水深度。
