I've checked the ACEEE list and it only includes cars. The main form of transport in Vietnam is a 50cc scooter and it is certainly fuel-efficient. Honda is the most popular brand here and models range from 50mpg-140 mpg averaging in the mid-70s. I will ask the reviewers what they propose but I'm wondering if anyone has experience with listing motorbike mileage or whether any 50cc motorbike was accepted or whether they were all rejected because they're not on the ACEEE list. My previous EBOM project bused everyone from the nearest city so we didn't need to list motorbikes.....
