Physically, traveling faster takes more power, so there's no getting around that.
If the slower speed had the transmission downshift that might partially explain the difference. Generally, going as slowly as possible in top gear is most efficient.

its pretty much a flat grade pretty much FLOORING it from 0 to 45 nets about 20-22
going slowly from 0 to 45 is a net loss of 9-10mpg it will read about 13-15mpg on the fuel meter whole time tell i reach speed ( 47-48mph) then jump to 23-29 on the meter
the top gear is at 30mph in 4 speed mode
EVT mode(eco mode) the top gear or ratio is at 47mph (sometimes shifts if I let off the gas) the engine is at 1050 to 1100 rpm 6th gear
i don;t think the trasmssion is messed up
Maybe the battery is too far depleted ?
it has a hybridized automatic transmission 4 speed launch gears 0-60 in 6.5 seconds (assuming a new hybrid battery)
6.0L engine if that matters i disabled the AFM as it's risky business keeping it enabled (replacement engine COST $6,000) or 2,000 to repair it
it's always in V8 mode....
the 2mode transmission does not down shift once in eco mode you can ride 1,000RPM to 0MPH ( DFCO )from 50mph
No engine braking, only from the regen which is very light almost undetectable ( unless on the "M4 gear" 4 speed fixed gears then you get engine braking )
