Had a very fast and smooth ride on this Euro5 hybrid E400.
Came across this working using London Vehicle Finder, so went for a ride on it. It was a Euro5 E400H, and these buses are extremely rare on the route, could have been the first time! Also, these buses are faster and rides are very smooth. In my opinion, these are better than the Euro6's but pollution is obviously something that needs to be fixed, and so Euro6's are more ideal with their reduced pollution/emission credentials.
