Many humans could be said to run on coffee, but now there's a car that will use the magic beans to power a trip from Manchester to London.
Giving a new meaning to the expression 'coffee to go', the experiment is part of BBC 1's science programme Bang Goes the Theory.
According to the Daily Mail, the second-generation 1988 Volkswagen Scirocco on which it's based was chosen for its resemblance to the famed time-travelling DeLorean from Back to the Future - and cost a mere £400.
However, the so-called Car-puccino isn't exactly grounds for celebration, as it gets through a latte of coffee. With a burn rate of a kilo every three miles, the 210-mile journey is set to use the equivalent of 11,760 espressos.
So, although the experiment is an attempt to show you don't have to rely on petrol and diesel to fuel a car, the Mail's maths puts the cost at 25-50 times that of just running on petrol - depending on the quality of the coffee beans you buy.
Bang Goes the Theory producer Nick Watson explained that the coffee needs to be very dry and in pellet form, allowing air to circulate as it burns, though he stressed that the "brand doesn't matter" - something that could grind the gears of coffee-connoisseurs.
"Coffee, like wood or coal, has some carbon content, so you can use it for fuel," he added.
Interestingly, the flat-white Scirroco is not the first coffee-themed car. The Suzuki Cappuccino, with its minuscule, turbocharged engine, is said to be quite a frothy little drive.
