[ 新车官图] 近日,我们从官方获悉,日产Armada NISMO(国内途乐(参数|询价))官图正式发布。日产Armada迎来首个NISMO车型,NISMO为这款大型SUV注入了更鲜明的风格和操控提升,进一步提升驾驶体验。新车将搭载3.5升双涡轮增压V6发动机,最大功率为460马力,相比普通版车型提升了35马力。
外观方面,新车提供5种外观颜色,融入了NISMO的标志性风格套件,提升了车辆的空气动力学表现。

B | 新车的前后保险杠、格栅、侧踏板和后扰流板均由NISMO设计,赋予这款SUV更具性能导向的外观。

C | 翼子板轮拱的宽体设计为标准配置,营造出更宽大、更霸气的姿态。Armada NISMO还配备了LED前雾灯和红色喷涂的制动卡钳。

D | 专属的NISMO锻造合金轮圈,直径达22英寸,搭配更高性能的轮胎,有助于优化车辆的操控、转向、制动和加速性能。    Breakthrough new research could significantly increase supply of organs for people with rarer blood types waiting for a transplant, reported The Guardian.,A team of scientists from the University of Cambridge have successfully altered the blood type of three donor kidneys. By flushing blood infused with a special enzyme through a human kidney the scientists removed the blood type markers lining the blood vessels of the organ.,The procedure required using a device that is connected with a donor’s kidney to pass oxygenated blood through it - a normothermic perfusion machine. As a result, the organ was converted to type O, considered the universal donor.,Blood Group Compatible,As the blood type of a donor must be compatible with the recipient’s, the new development could increase the supply of kidneys available for transplant.,A kidney from someone with blood type A cannot be transplanted to someone with blood type B, or visa versa. In such a case, the receiving body’s immune system would reject the new organ, interpreting the different blood type as foreign.,So changing the blood type to the universal O would mean the donor organ could be used for people with any blood type.,“Our confidence was really boosted after we applied the enzyme to a piece of human kidney tissue and saw very quickly that the antigens were removed. After this, we knew that the process is feasible, and we just had to scale up the project to apply the enzyme to full-size human kidneys,” Serena MacMillan, a PhD student at the University of Cambridge, said.,Scientists involved in the research, funded by charity Kidney Research UK and due to be published in the British Journal of Surgery, clarified that the outcome might have particular implications for minority ethnic groups.,Science & TechGood News for ABs: Scientists Can Now Change People's Blood Type21 February, 16:34 GMT,Some blood groups such as O Rh positive and B Rh positive are more prevalent among black, Asian and minority ethnic communities. To complicate matters further, some rare blood types are only found within the black, Asian and minority ethnic communities,This typically places them at a disadvantage, as they struggle to find a match. With low donation rates from these populations, stressed the researchers, sometimes such patients wait for as long as over a year for a compatible donor. They cited figures from 2020-21 showing that just over 9% of total organ donations in the UK came from black and minority ethnic donors. On the other hand, black and minority ethnic patients make up 33% of the kidney transplant waiting list.,“It’s very exciting to think about how this could potentially impact so many lives,” added Serena MacMillan.,The “potentially gamechanging” research was applauded by Dr Aisling McMahon, the executive director of research at Kidney Research UK.,The scientists will now test the reintroduction of other blood types and observe how the novel approach in clinical settings.。

内饰方面,NISMO专属的绗缝皮革装饰采用炭黑色调,搭配红色点缀和缝线。其他新增配置包括带可调侧支撑的前排座椅、铝制踏板以及多色氛围灯。同时,新车将提供日产Klipsch12扬声器音响系统,还可选配ProPILOT Assist 2.1辅助驾驶系统。
动力方面,日产Armada NISMO搭载的3.5升双涡轮增压V6发动机,最大功率达到了460马力,配备9速自动变速箱。重新调校的排气系统让发动机声浪更为洪亮,并且座舱内的主动声音增强技术进一步放大了发动机声效。NISMO的专属调校使电动助力转向带来更运动的转向手感,自适应电子空气悬架进一步提升操控性。(文/ 姚宇)
