The web site has the following description of the range of the Mission R:
With power densities previously unheard of for electric motorcycles, and over 17 kWh of stored power, the UltraPack™ not only allows for the world's best superbike performance, but also a real-world range of over 140 miles as measured using the Motorcycle Industry Council’s (MIC) SAE combined cycle standard, at 70 mph highway steady-state speed.
The various battery sizes list the following ranges:
12kWh, 170 mile city, 105 mile "real world"
15kWh, 200 mile city, 120 mile "real world"
17kWh, 230 mile city, 140 mile "real world"
The description includes text that describes two separate and conflicting standard range measurements. They clearly say "70mph steady-state" which would imply they are quoting the pure highway range, but they also clearly state "SAE combined cycle standard" which mixes the 70mph range with the city range.
The "real world" ranges they list are about 60% of the advertised city ranges - which is about the same as the ratio of the Zero S hwy/city, and about the same as the Empulse combined/city ratio.
The Mission R has a fairing to help with highway range, but it is probably heavier than the Zero (and probably the Empulse too) which would have an impact as well. It's also a sportier bike than either which would tend to suggest that a "real world range" for it would be geared more towards highway speeds, no?
I'd love to think that the "real world" range is a pure highway range, but have no idea how to compare all of these data points with the confusing language.
