The key to winning any drag race in Mexico

If you possess some knowledge about cars, the chances are you know that altitude affects how much power an engine produces.

What isn't as well known, however, is just how much of a difference this can make.

For internal combustion engines, an estimated 1% of power is lost for every 100 metres above sea level.

This really starts to add up when you go to places like Mexico City, which sits at 7,382ft above sea level.

As turbochargers force air into the engine with the same pressure regardless of altitude, the power produced remains the same.

All it means is that turbos have to work harder, making them more unreliable.

But this doesn't matter when your primary goal is to show up a 'superior' car on a drag strip.

Especially a drag strip like Toluca - 8,750ft above sea level - which provides some interesting results when, for instance, a CUPRA is pitched up against a Mustang.

Basically, owning a car with a normally aspirated engine near Mexico City is one way of ensuring you'll be shown up by a turbocharged 'underdog' at some point.

Need more proof?

Sorry 370z, it's your turn to be embarrassed.

This time, a different CUPRA takes on a different Mustang.

But the outcome is the same.

I think everything I've ever learnt about cars has just gone out the window...
