Today a bit off-topic.
Took a 850km trip with a borrowed Opel Astra with a 1.7 diesel engine (CDTI probably) and a 6-speed gearbox. Talk about effortless FE!
Of course I couldn't resist and slapped a piece of cardboard on it
I don't know if it helped, but in theory it should have, right? The final result: 4.8 l/100 km over 850 kms. I just can't imagine doing this trip with the 'cento. It would either take twice as long or end up burning almost twice as much fuel while being quite noisy and not that comfortable.
Also, an interesting vessel that I caught.
