(CNN) 梅赛德斯推出了一款全新的全电动概念车 EQXX,该公司声称一次充电可行驶 620 英里。这款未来派豪华汽车还采用了大量创新的可回收和可持续材料制成,包括蘑菇纤维、磨碎的仙人掌和食物残渣等垃圾。
该公司表示,梅赛德斯对这款概念车的续航里程声明是基于计算机模拟测试,而非实际驾驶。根据美国环境保护署的估计,如果声称是准确的,那么 EQXX 一次充电将能够比丰田普锐斯混合动力车用一整箱汽油行驶更远。普锐斯只能行驶 588 英里。柴油驱动的雪佛兰 Suburban 可以使用 28 加仑的燃油箱行驶 644 英里。据美国环保署称,它也比美国目前可用的任何其他电动汽车都要远得多。
该公司表示,梅赛德斯计划在今年春天的实际驾驶测试中展示这款车的续航里程。
梅赛德斯曾表示,它计划到 2025 年将其一半的销量用于电动汽车,到 2030 年,该品牌几乎“准备好走向全电动”。梅赛德斯将 EQXX 称为“批量生产的技术蓝图”。不过,尚不清楚梅赛德斯是否打算在真正的生产模型中使用所有这些技术,或者所有这些技术是否都接近可用于生产。
据梅赛德斯称,EQXX 的电池组比德国汽车制造商目前的全电动轿车梅赛德斯 EQS 的电池组大一半,重量减轻 30%,从而实现了其非凡的续航里程,同时存储了相同的能量。在 620 英里或 1,000 公里处,EQXX 充电后可提供比 EQS 多约 133 英里的行驶距离,这是基于该车的欧洲范围估计。
根据梅赛德斯的说法,EQXX 主要通过效率获得了这些额外的里程。梅赛德斯声称 EQXX 每千瓦时的电力可以行驶超过 6 英里。根据美国环保署的估计,这几乎是特斯拉 Model S Long Range 每千瓦时的三倍。千瓦时是存储在汽车电池中的电能单位,因此每千瓦时的英里数就像汽油车每加仑英里数。不过,这个数字要低得多,因为一加仑汽油含有近 34 千瓦时的能量。
为了达到这种效率水平,梅赛德斯的设计师专注于空气动力学。 EQXX 的阻力系数仅为 0.17,比正确投掷的足球更具空气动力学特性。它也比今天的梅赛德斯 EQS 更符合空气动力学,虽然仍然非常符合空气动力学,但风阻系数为 0.20。据保时捷称,保时捷 911 Turbo 的风阻系数为 0.33。
据梅赛德斯称,这款车的设计也尽可能轻。除了相对较轻的电池组外,它还配备了镁制车轮和铝制制动器。 EQXX 悬架中的弹簧由玻璃纤维增强塑料而非金属制成。
EQXX 的车身包括一个类似网状的副车架,旨在仅在结构完整性和碰撞安全实际需要的地方使用金属。框架中的空白空间填充了一种名为 UBQ 的材料,由一家以色列初创公司创建。据梅赛德斯-奔驰称,UBQ 是由垃圾填埋场垃圾制成的,其中可能包括混合塑料、纸板、园艺垃圾甚至尿布。屋顶的太阳能电池板为空调、灯和汽车的触摸屏系统等设备提供补充能量,从而减少对电池的需求。
除了车身中的 UBQ 填充材料外,EQXX 还在汽车的其他部分使用了可持续材料。由菌丝体制成的皮革状材料,蘑菇的地下根状结构,用于座垫。另一种皮革替代品,由粉碎的仙人掌纤维制成,用于内饰的其他地方。据梅赛德斯说,地毯完全由竹纤维制成。
在内部,EQXX 有一个巨大的触摸屏,可以在仪表板上一直延伸。与 EQS 中的超宽“屏幕”实际上是一块玻璃下的三个较小的屏幕不同,EQXX 中的那个实际上是一个四英尺宽的屏幕。为了节省能源,屏幕未使用的部分会变暗。
梅赛德斯的工程师和设计师还试图让汽车的语音控制系统更具个性,声音更逼真,更能表达情感。该系统由一个由小星星组成的人形化身代表。该模型以年轻的梅赛德斯·杰利内克 (Mercedes Jellinek) 为模型,埃米尔·杰利内克 (Emil Jellinek) 是戴姆勒 (现为梅赛德斯的母公司) 的早期客户(尤其是苛刻的客户)。
1900 年,他委托了一款新的跑车模型,他坚持以他女儿的名字命名。 这辆车非常成功,以至于她的名字后来被贴在公司生产的每一辆车上。
Mercedes says its electric concept has 620 miles of range and seats made with mushrooms
(CNN)Mercedes has unveiled a new all-electric concept car, the EQXX, that the company claims can go 620 miles on a single charge. The futuristic luxury car is also made with a host of innovative recycled and sustainable materials including mushroom fibers, ground up cacti and trash such as food scraps.
Mercedes' range claim for this concept vehicle is based on computer simulated testing, not actual driving, the company said. If the claim is accurate, though, the EQXX would be able to drive farther on a single charge than a Toyota Prius hybrid can travel on a full tank of gas, according to United States Environmental Protection Agency estimates. The Prius can only manage 588 miles. It's nearly as far as the 644 miles that a diesel-powered Chevrolet Suburban can go on a 28-gallon tank of fuel. It's also much farther than any other electric car currently available in the United States, according to the EPA.
Mercedes plans to demonstrate the car's range in an actual driving test this spring, the company said.
Mercedes has said it intends for half its sales to be electric cars by 2025 and, by 2030, for the brand to be virtually "ready to go all electric." Mercedes referred to the EQXX as a "technology blueprint for series production." It is not clear, though, if Mercedes intends to use all of this technology in a real production model or if all of it is close to being viable for production.
The EQXX achieves its remarkable range with a battery pack that is half as large and 30% lighter than the one in the Mercedes EQS, the German automakers current fully electric sedan, while storing the same amount of energy, according to Mercedes. At 620 miles, or 1,000 kilometers, the EQXX would provide about 133 miles more driving distance on a charge than the EQS based on European range estimates for that car.
The EQXX gains those extra miles largely through efficiency, according to Mercedes. Mercedes claims the EQXX can travel more than 6 miles per kilowatt hour of electricity. That's almost three times farther per kilowatt hour than a Tesla Model S Long Range, according to US EPA estimates. A kilowatt-hour is a unit of electrical energy stored in a car's battery so miles per kilowatt hour is like miles per gallon for a gasoline car. The figures are much lower, though, because a gallon of gasoline contains almost 34 kilowatt hours of energy.
To reach that level of efficiency, Mercedes designers focused on aerodynamics. The EQXX has a drag coefficient of just 0.17, which is sightly more aerodynamic than a properly thrown football. It's also more aerodynamic than today's Mercedes EQS which, while still very aerodynamic, has a drag coefficient of 0.20. A Porsche 911 Turbo has a drag coefficient of 0.33, according to Porsche.
The car is also designed to be as light as possible, according to Mercedes. Besides the relatively light battery pack it has wheels made from magnesium, and aluminum brakes. Springs in the EQXX's suspension are made from glass-fiber reinforced plastic instead of metal.
The EQXX's body includes a web-like subframe designed to have metal only where it's actually needed for structural integrity and crash safety. Empty spaces in the frame are filled in with a material called UBQ, created by an Israeli startup. UBQ is made from landfill waste that can include things like mixed plastics, cardboard, gardening waste and even diapers, according to Mercedes-Benz. Solar panels in the roof supply supplemental energy for things like air conditioning, lights and the car's touchscreen systems reducing demands on battery power.
Besides the UBQ filler material in the body, the EQXX also utilizes sustainable materials in other parts of the car. A leather-like material made from mycelium, the underground root-like structures of mushrooms, is used in the seat cushions. Another leather substitute, made from pulverized cactus fibers, is used elsewhere in the interior. The carpets are made entirely of bamboo fiber, according to Mercedes.
Inside, the EQXX has an enormous touchscreen that stretches all they way across the dashboard. Unlike the ultra-wide "screen" in the EQS, which is actually three smaller screens under a single sheet of glass, the one in the EQXX really is a single four-foot wide screen. To save energy, unused portions of the screen dim.
Mercedes engineers and designers have also tried to give the car's voice-control system more personality with a lifelike voice that's more emotionally expressive. The system is represented by a human-shaped avatar made up of tiny stars. The figure is modeled on the young Mercedes Jellinek, the daughter of Emil Jellinek, an early (and particularly demanding) customer of Daimler, now Mercedes' parent company.
In 1900, he commissioned a new sports car model that he insisted be named after his daughter. The car was such a success that her name later became attached to every car the company made.
