Is there a workaround for the trunk?
No known workaround for the trunk not 'popping' open, but you're in good company on this as others have commented on this as a feedback point for Honda. Would be interested if someone compared trunk opening on a GenX Civic and GenX Accord to see if they have a spring release (like older Hondas do) or if they're also like the Insight.
Also be thankful that you're at least able to close the trunk (even with force) versus issue that some have experienced with trunk not staying closed OR causing security alarm to go off - https://www.gen3insight.com/forum/28...ay-closed.html
Rough running on startup, have others had this issue?
Assuming you're referring to roughness at startup with gas engine, several of us have been discussing and theorizing reasons in the following thread - https://www.gen3insight.com/forum/15...e-misfire.html
The vibration is primarily associated with the gas engine running (never while on electric engine) and mainly seems to occur when engine is cold (or even after warm start). Ambient temperatures and/or climate control demand triggering the gas engine at start up also seem to be triggers. I'm hoping that we gather enough data and/or reports of this across the forum to report back to Honda so it becomes a known issue for Honda to fix or explain.
How does the HP rating work? I understand the engine couples at freeway speeds and the power flow on HUD indicates this with a gear symbol. Is the total output 107hp rather than 151hp? Since the icu is generally not engaged during normal acceleration it is really only capable of attaining the full hp rating at highway speeds since the icu is not engaged. Is this a correct assumption?
The hp, torque, and rpm output varies depending on whether the gas or electric (or both) are running as sole power. Once the HV battery is low/depleted and the gas engine is the only power source, the Insight's peak power is 'only' 107 hp and 99 lb-ft torque. When only the gas engine is running as sole power, it's a lower HP, lower torque, and higher RPM output:
GAS ENGINE ONLY = In-Line 4-Cylinder
107 HP @6000 RPM -- 99 lb-ft torque @5000 RPM
ELECTRIC MOTOR ONLY = AC Synch Magnet
129 HP @4000-8000 RPM -- 197 lb-ft torque @0-3000 RPM
TOTAL SYSTEM = peak concurrent output of the 2 electric motors & gas engine (**the RPMs for combined condition are guesstimated)
151 HP @6000 RPM** -- 197 lb-ft torque @0-3000 RPM**
Also for calibration on terminology, I think HUD (head-up display) is typically used to describe the projector-like display onto the windshield within the driver's natural range of view to allow them to keep their "head up" while driving. The Insight has a Drivers Information Interface (DII) behind the steering wheel, and an infotainment screen (aka head unit) in the center area. Some ways to add an aftermarket HUD to the Insight are suggested in the following thread - https://www.gen3insight.com/forum/29...p-display.html
