What's the fastest accelerating car in the world that you can buy without a special order and for a relatively¹ affordable² price compared to other high performance cars?

世界上跑得最快、而且你还不用特意预订、并且跟其他高性能车相比价格非常良心的车是什么？

Instead of a roaring, super-charged, high-octane-gasoline guzzler³ and air polluter it is an all-wheel drive electric car that can reach 96.5 kilometers an hour in just 2.5 seconds. Its two electric motors are almost silent and its wheels do not slip.

它的引擎声没有那么响，机械增压也不强，汽油辛烷值也不高很环保，它是一辆四轮驱动的电动车，在2.5秒内就可以加速到每小时96.5公里的速度。它的两个电动引擎几乎是无声的，轮胎也不滑。

Founder⁴ and CEO of Tesla Motors Elon Musk⁵ Tuesday unveiled the new four-door sedan Tesla Model S P100D with an improved 100 kilowatt-per-hour battery that also makes it the longest range electric car. Fully charged, it can run for over 600 kilometers.

特斯拉汽车公司创始人兼首席执行官埃隆·马斯克上周二公布了新型四门轿车特斯拉P100D的，这款车配备了改进过的100千瓦时电池，使其能行驶更多里程数。在充满电的情况下，它可以行驶超过600公里。

The same battery is now available in Tesla's Model X SUV, which accelerates slightly slower – only 2.9 seconds to 96.5 kilometers an hour. That is also a record for SUVs together with its improved range of 542 kilometers.

而现在特斯拉Model X运动型多功能车上也搭载了相同的电池，不过加速有点慢--加速到每小时96.5公里要用2.9秒。这种运动型多功能车在充满电的情况下可以行驶542公里。

Both models can be recharged for free at the ever-expanding network of Tesla's Supercharger stations.

这两款车都可以在遍布各处的特斯拉超级充电站进行免费充电。

According to Musk, the improvement comes not from the battery technology but from new electronic circuits that make better use of their charge.

据马斯克表示，提升不仅体现在电池技术上，也体现在可以更好地利用电能的电子电路上。

The new Model S starts at $134,500 while the cheapest of its competitors, Porsche 918 Spyder starts at $845,000.

新的Model S型车的起步价是13.45万美元，是相似车型中是最便宜的，保时捷918敞篷版的起步价是84.5万美元。
