Jeremy Clarkson, Richard Hammond and James May conduct a valuable piece of consumer research with their attempts to improve and enhance the ambulance.

Starting with a belief that current ambulances, which are usually very big and based on a diesel van, are in need of a rethink, the presenters go their separate ways to focus on the one area they think could be improved. May focuses on passenger comfort, Hammond tries to improve response times by getting other drivers out of the way more effectively, while Clarkson confronts the same issue with the invention of what he calls 'the sports ambulance'.

Their three very different creations are then put to the test with a series of severe and often messy challenges, culminating in a fast reaction to a spectacular emergency.

Also in this episode, F1 driver Daniel Ricciardo is the star in the Reasonably Priced Car.

Top Gear Show Summary

BBC's hit motoring show is more than just a show to review new cars. Top Gear is essential viewing. Not just for petrol heads, it also has a huge following amongst people with little or no interest in cars - both male and female. This is due to the show's irreverent approach to motoring, the humour and the priceless chemistry between the show's presenters - Jeremy Clarkson, Richard Hammond and James May, with special appearances from the tame racing driver, The Stig.

Don't be fooled, this is not another boring technical car programme, there is carnage, mayhem and fun, with less stuffy mundane car reviews. The boys have races and do crazy things with cars - anything from driving them into swimming pools to setting them on fire!
