新奇事件簿 特斯拉SP90D款轿车2.9秒破百
A new, upgraded version of an electric car from Tesla Motors is capable of going from 0 to 100kph in just 2.8 seconds. The original 691 horsepower Tesla Model S P85D was already incredibly fast. It even had a function called Insane Mode, which meant the car could get from 0-100kph in 3.2 seconds. The upgrade is called Ludicrous Mode and will take the horsepower up to 762, thus providing the extra power to get to 100kph in less than three seconds. This is close to the acceleration of a Porsche 911 Turbo S supercar. That kind of horsepower means the car can accelerate at a force of 1.1G. This means the acceleration will make the driver feel that he or she is going faster than the speed of falling out of an airplane.
特斯拉一款新型升级轿车能够在短短2.8秒内达到每小时100公里的速度。691功率马力的特斯拉SP85D型号轿车的速度惊人。该款轿车有一个名叫“疯狂模式”的功能，这就意味着轿车能够在3.2秒内达到每小时100公里。而升级版的“滑稽模式”能够让马力达到762功率，这样就为轿车在3秒内提速到100公里每小时提供了足够强大的动力。而这也接近了保时捷911TurboS跑车的速度。这种马力能够提速到1.1G的重量。这就意味着这样的速度能够让驾驶员感觉到这比从飞机上降落的速度还要快。
Tesla CEO Elon Musk explained that the new improvement in acceleration came from research into an advanced battery. Engineers were working on a new power train for its cars. A power train is the system that delivers the power from the engine to the wheels. The engineers managed to increase the battery power by ten per cent, resulting in the extra acceleration. Tesla said: "Unlike a gasoline internal combustion engine with hundreds of moving parts, Tesla electric motors have only one moving piece: the rotor. As a result, Model S acceleration is instantaneous, silent and smooth." The Tesla S P85D car is priced at $87,500 as a basic model; the "ludicrous" upgrade will be an extra $13,000.
特斯拉首席执行官伊隆·马斯克解释道速度上的提升要归功于对电池的研究成果。工程师正在对轿车的动力传动系进行改变。动力传动系能够将来自引擎的动力传送到轮胎上。工程师已经在原有基础上将电池动力增加了10%，并最终成功加速。特斯拉称：“不像内燃机有上百个可替换标准件，特斯拉的电动机只有一个：转子。所以，S型轿车的加速是瞬间、安静、平滑的。特斯拉SP85D型轿车的基本型售价8万7500美金；“滑稽模式”升级版将再增加1万3000美金。
