@kezo My similar-sized former vehicle Toyota RAV4 (also hybrid) managed to attain just 38mpg over 5+ years.
Over the last 4 months of having the Nissan X-Trail, I’ve attained 44.3mpg. I mostly drive with it in eco mode, and as the last 4 months have been warmer than the average over 5 years, I’d assume that will likely come down to that of similar economy as the RAV4.
