The Renault Twizy is the star of a new concept for tourists in Paris. Twiztour invites visitors to get behind the wheel of a Twizy and see the sights of the French capital following a special tourist-friendly GPS route. Alternatively, they can opt  for a personalised tour by following a guide who is also driving a Twizy!

The all-electric Twizy is ideal for zipping around the narrow cobbled streets of Paris and has the added benefit of being easy to park in the smallest of spaces – something that is not negligible in Paris's busy streets.

It’s probably the smallest – and perhaps the most unlikely – fire fighting machine in the world, but its size will help the tiny Renault Twizy to save lives.

Resplendent in red and white, and with a blue light perched on its roof, the all-electric Twizy has joined the Paris fire brigade for front line duty. Thanks to its ability to squeeze through gaps and go places where a conventional fire truck cannot go it offers early intervention at an incident, providing life saving support before the big guns arrive.

Big excitement today as Nissan showed off the TeRRA FCEV concept that it's going to bring to the Paris Motor Show later in September.

What's an FCEV I hear you ask? Simple, it stands for Fuel Cell Electric Vehicle. What's a fuel cell then? Even simpler; it's like a battery that uses fuel. You put hydrogen in, it gets combined with oxygen, which generates electricity that goes to turn the wheels and power the car. And the only thing that comes out of the exhaust is water. How? Because if you combine hydrogen (H) and oxygen (O2) you get H2O – water.
