Well this brings a whole new meaning to caffeine-fuelled.
The 'car-puccino' was unveiled this month and does exactly what it promises - it runs on coffee.

(And yes, the 1988 VW was chosen for its likeness to the DeLorean from Back to the Future).
Here are the top ten things you need to know about it:
1. It was built by a team from the BBC1 science programme Bang Goes The Theory
2. It's been designed to show how fuels other than conventional petrol and diesel can power vehicles
3. It's powered *only* by roasted coffee granules
4. It goes three miles for every kilo of ground coffee (that's about 56 espressos per mile)
5. It will use about 70 kilos of ground coffee on its journey (and cost 25 - 50 times the price of petrol)
6. The team will be taking 'coffee breaks' (pouring in more coffee) about every 30 - 45 miles
7. The journey will take about 10 hours in total
8. The gasification process used could also power a car on construction debris, agricultural waste or landfill
9. To save money and help the environment, it will be powered by waste coffee grounds from Costa Coffee
10. It's going on display at the Big Bang science fair in Manchester if you want to see it...
But if you can't make it to the fair, you can get your science geek fix here:
