UK students have driven an electric car around Greater London twice on a single charge. Using a specially modified electric Radical SRZERO supercar, the Racing Green Endurance (RGE) team from Imperial College completed two laps of the M25 motorway in the wee hours of Friday morning, covering a total distance of 250 miles (400km). The feat is a lead up to an attempt later this year at becoming the first EV to conquer the longest road on Earth - the Pan American Highway.

Built on a Radical Sportscars SR8 chassis and using two lightweight motors designed and built by an Imperial spinout company - EVO Electrics, the 1100 kg SRZERO boasts the specs to back up its "electric supercar" label: a top speed of 200kmh, 0-100 kmh in 7s, a full charge in 6 hours and a 200 mile / 400+ km range.

The open-top SRZERO must have been quite a sight as its balaclava wearing drivers steered it around the ring road in the middle of the night. The first lap was completed at 55 mph using 42% of the total energy and ramped up to 60 mph the second time around.

In July the Imperial College team plans to take on the Pan American highway, aiming to cover more than 16,000 miles (26,000 km) through 14 countries from the northern tip of Alaska to the southern tip of South America.

This epic trip is designed to both change public perception of electric cars and evaluate the capabilities of electric vehicles over long distances.

The Tesla roadster previously held the M25 record, having completed one lap of the M25 on a single charge. The Roadster also traveled 313 miles on a single charge last year on the empty roads of the Australian outback and is currently embarked on its own long range testing odyssey in which it will travel 22,000 miles through Europe, Asia and North America.

It\'s an electric freaking car! I already know it will go 100,000 with no maintenance!!! Save the money on your Pan American Hwy trip. Instead give me an SUV that can sit in summer rush hour traffic for 3 hours with full Air Conditioning running and still get me home. Do that and we will buy it!!!


The range is looking impressive... though I think they won\'t get past Bogota on the pan-American trip, as some drug lord is going to want the thing for silent/speedy getaways.

But as I\'ve posted elsewhere, I think the G20 (say) ought take an interest in electric vehicles and put to every country that it needs to make vehicle design rules a bit more lax for (say) zero-emission commuter vehicles controlled to travel at under 75kph/45mph. A super-efficient vehicle should not be discriminated against just because it does not carry enough heavy-metal to sustain a 100kph/60mph front impact collision, if the primary purpose of the vehicle is for intra-city peak-hour commuting, when traffic is so heavy as to preclude high-speed impacts. Internal combustion cars only got established in an era when there were not lots of design rules - these things really impede innovation. We need to get off oil more than we need 10 airbags in every vehicle. The way to lessen lightweight vehicles interaction with trucks and heavy-metal cars is to provide dedicated nil-emission lanes on commuter freeways. Then we\'d get innovation, like mountain bike wheels and componentry supporting light-weight space-frames with smallish battery packs and multiple all-electric drive systems. These light-weight cars should have all safety lights (indicators etc) but no heavy bumper bars, airbags or the rest crap we now carry around with us in our vehicles.

And we need governments around the world to stop trying to outlaw things which blur the line between a bicycle and an electric scooter. Many countries limit the amount of \'assistive power\' a bicycle can have to only 200w, which is nothing. The driving force is of course a fear of loss of vehicles registration income, but we should encourage all more efficient forms of transport. The governments will still find ways to tax everyone!

@Graeme I like the direction you are going. Home-built airplanes do not have the same requirements as commercially produced airplanes. Home built EVs and high mileage personal commuters should have relaxed certification rules. Check out They have produced 100+mpg cars that can be bought for $25,000 and conform to all safety and road-worthiness regulations.
