And it's one that you could actually sleep in.

When you see a white Renault Kangoo casually strolling through the streets of London, you would probably think that it's on its way making a neighbourhood delivery. The French passenger/cargo van isn't something that you'd think would go flat out– well, not if it has a Megane RS engine under its bonnet.

Youtube's Monky London was able to spot this sleeper, which, according to the owner, was a van from his sister. It's a panel van, as you can see, and its humble utilitarian design is hardly representative of the speeds and acceleration it is capable of putting down.

The owner of the "Megangoo" used three Renaults to create the mother of all sleepers. Aside from the Kangoo body, a Clio 172's gearbox was used to transfer all the power from the turbocharged Megane 225 engine. To put things in contrast, let's look at all three cars.

The Kangoo I is a passenger and cargo van that was introduced in 1997 and ended production in 2007 to make way for the Kangoo II. This particular unit is a panel van where the rear seats have been removed to be specifically used to transport cargo. It was originally powered by a diesel engine, which is why you wouldn't expect it to tear down open streets.

The Clio, on the other hand, is a subcompact hatchback that has been consistently one of Europe's top-selling cars since its launch. Being a small car, it's an economical choice but it has an RS trims that could surprise you.

Lastly, the Megane RS is a hot hatch that could easily go head to head with the Honda Civic Type R and Hyundai i30 N. This turbocharged 225 engine is from the first-generation of the Megane RS, capable of producing 222 bhp in its stock form.
