Back from an
impromptu sailing trip , first order of business was getting plates and insurance on the UFO.
It's legal!
And on a drive today to a cottage I've done many times in the heavily modified Firefly that would have returned about 70-75 mpg (US), I netted
98 mpg US (2.4 L/100 km) in this unmodified Insight.
(That's not entirely true: it's currently modified, in the sense that the hybrid system is
disabled - main switch thrown on the battery pack).
Main driving technique used: driving with load, on quiet rural roads, at moderate speeds. Average was likely ~70 km/h (44 mph). Engine-off coasting to stops and some turns.
To get that kind of mileage from the Firefly, I would have had to pulse and glide the entire distance, and at a considerably slower average speed.
After I get a few hundred unmodified kilometers on the car to get a baseline... let the mods begin!
Lean burn stumble?
The violent "herky jerky" problem remains cured.
But I believe the transition to lean burn mode is still fairly evident: The instant fuel consumption drops noticeably on the FCD (fuel consumption display); throttle response becomes somewhat deadened and uneven; and there are occasional "stumbles" from the engine.
Anyone care to comment if this is normal? It would be interesting to have driven a brand new Insight to compare.
