宝马与特斯拉电动汽车大战升级
|
3. 里程 对于电动汽车来说，最重要的莫过于一次充电的续航里程，不过仪表盘上的续航里程跟我们在真实世界里跑出的里程通常不可能完全一致。特斯拉表示，凭借Model S超牛的电池，它可以一次性跑300英里。不过专业汽车网站Edmunds.com的一位试驾员却表示，他在跑了121英里之后，仪表盘上的里程就显示他已经跑了251英里，让他在之后的回家路上有些惴惴不安。 宝马表示，用户可以选择在i3上安装一个像摩托车引擎一样的汽油增程发动机，从而可以让这款车型再多跑186英里，以避免车子因为没电了而尴尬地在路上“罢工”。另外据说i3一次充电后就可以跑93英里。但是在这款车型最终上市以前，一切都还不能肯定。 优势方：平手 4. 缓解“里程焦虑症” 特斯拉将在加州和东北各州以外扩展它的快速充电站网络，预计等到这个项目结束时，全美将有大约200个快速充电站。另外特斯拉还在今年六月展示了它的换电池技术。通过两辆Model S的演示可以发现，它们换电池的速度比普通汽车在加油站加油差不多要快两倍，而且无需司机下车。 宝马i3上的一块显示屏可以显示附近充电站的位置，同时宝马也会在某些地区提供道路救援服务。不过这种道路救援服务并不是拖车服务，而是先给你充一定量的电，使你的i3有足够的电量赶到下一个充电站。 优势方：特斯拉 5. 技术 特斯拉最大的技术成就就是它成功地无缝整合了该车的所有部件，尤其是那个由7,000块小电池组成的动力系统。同时它迈出了不同寻常的一步，就是自行制造汽车元件，比如铝合金车身面板和塑料件等，而不是像其他厂商那样从外部采购。 宝马在研发上同样不惜血本。宝马i3采用了铝合金底盘，而轿厢部分则大部分应用了轻量的碳纤维材料，这也是量产车第一次采用这种技术。因此宝马表示，这台四门电动汽车的重量只有2800磅左右，比雪佛兰沃蓝达（Chevrolet Volt）轻了大约1000磅。 优势方：平手 |
3. Range In electric cars, what counts is how far you can go on a single charge, and the range numbers that are displayed on the instrument panel usually can't be duplicated in the real world. Tesla says the Model S can travel up to 300 with a beefy battery. But an Edmunds.com tester discovered he burned up 251 miles of indicated range after covering just 121 miles, which made his ride home a bit uncomfortable. The i3 will have an optional range extender, a motorcycle-like gasoline engine that can power the car for 186 miles, BMW says, which should prevent embarrassing roadside breakdowns. Otherwise, the car is said to be able to travel about half that distance, 93 miles, on a single charge. But we won't know for sure until the cars are actually on the road. Advantage: tie 4. Range anxiety reduction Tesla will expand its network of fast-charge stations beyond California and the Northeastern states and expects to have about 200 charging stations nationwide when it is completed. In addition, at a demonstration of its battery swap technology in June, Tesla showed two Model S sedans having newly recharged batteries installed twice as fast as they could get filled up at a gas pump and without the driver getting out of the vehicle. A display in the BMW i3 will show the location of nearby recharging stations and will also offer a roadside assistance program in some areas. The assistance vehicle will provide a jolt rather than a tow, so the i3 can scoot on to the next charging station. Advantage: Tesla 5. Technology The greatest technological achievement of Tesla has been its ability to successfully integrate all the components of the car, especially its 7,000-cell battery power system, without a glitch. At the same time, it has taken the unusual step of making in-house components that automakers usually outsource, like aluminum body panels and plastic pieces. BMW is no slouch either in R&D. The chassis of the i3 is made of aluminum while the passenger compartment is formed largely of lightweight carbon fiber, a first for a mass-production car. As a result, BMW says the four-passenger car only weighs 2,800 pounds, about 1,000 fewer pounds than a Chevrolet Volt. Advantage: tie |
