Nissan can see an upside to the tough new emissions rules in London and turn it into a great promotional opportunity. The London Congestion Charge has been tightened up so that the vehicles that are eligible for exemption from the hefty daily charge of 10 British pounds (a little more than $15 US) that it costs to access the city's downtown streets was recently revised from an emissions threshold of 100 grams per kilometer down to 75g/km.

Previously exempt low-emission cars like the Toyota Prius, Smart Fortwo and Fiat 500 TwinAir no longer meet the revised standard and are now subject to the daily toll. Battery electric cars like the Nissan Leaf and plug-in hybrids like the Vauxhall Ampera still qualify for exemption, though, which is why Nissan pulled a new marketing stunt. Nissan displayed what looked like a giant trash bin with three cars that don't qualify for the new rule jammed into it. The bin was plastered with "Skip the Congestion Charge" on its side, and you can see a cool photo of it over at Auto Express.

Nissan made another jab at competitors by stating that the Leaf can travel up to 500 miles for the price of a single day's congestion charge. Another selling point is that London has a lot of public charging stations – over 1,300 of them, and more than anywhere else in Europe.

The other EV models that qualify for exemption from the tightened congestion charge are the Renault EVs – Zoe, Fluence, Kango ZE and Twizy. Qualifying plug-in hybrids include the Toyota Prius Plug-in Hybrid, Vaxhaul Ampera, Chevrolet Volt and the upcoming Porsche Panamera E-Hybrid.
