Often ranked as one of the world's greenest cities, London is proud of its eco-friendly image and constantly embracing innovations that are gentle to the environment. That effort is most visible in the streets, which are dominated by double-deck hybrid buses and "Boris bikes" (rental bicycles named after the city's mayor Boris Johnson).
This weekend, thousands of motor racing fans will be gathering in the capital to witness the ePrix, the world’s first fully-electric racing series.
The inaugural Formula E series, which began last September in Beijing and will conclude in London’s Battersea Park on June 27-28, is out to prove to the world that motor racing can be exciting as well as environmentally friendly, without all the noise, fumes and gas-guzzling vehicles associated with the traditional Formula One series.
So how is Formula E different from the traditional car races? It’s all about the cars!
The vehicles racing in the ePrix are entirely powered by lithium-ion batteries, can accelerate from 0 to 62mph in about 3 seconds and hit a top speed of 140mph (compared to 233mph in Formula 1).
The drivers don’t need to refuel either, instead they just change cars in the pit since the batteries take too long to recharge.
電動賽車沒有內燃機引擎，用的是由鋰離子電池完全供電的電動馬達，0～62英里加速僅需約3秒，最高時速達 140 英里（一程式賽車的極限為時速 233 英里）。
The two-day event will take place on the Battersea Park Street Circuit, which follows the perimeter of the leafy park on the banks of the Thames.
So if you happen to be a motorsport lover and eco-warrior, this is the perfect way to spend a scorching weekend! Although most of the reserved tickets are already sold out, you can still enjoy the race from inside the park with a £8 ticket to the eVillage fan entertainment zone, which offers jumbo screens and a possibility of seeing the actual track.
Of course, you'll able to watch the London ePrix on TV and online.
