The MPG Marathon event took place earlier this month, with participants putting their economy driving skills to the test around a 370-mile route that included steep hills, twisting country lanes and inclement weather in southern England.
The “Overall Best MPG” winner of the event was a smart fortwo CDI. This particular smart vehicle is a tiny micro car that features one of the world’s smallest turbo-diesel engines – an 800cc, three-cylinder gas sipper. The smart notched a rating of 99.24 MPG over the two day event, the best figure ever recorded. This year makes it three wins in three tries for the smart CDI in the “Overall” event. Their winning mark was more than 15% better than the official combined fuel consumption figure of 85.6 MPG.
