2010 Honda Insight EX: How Noisy Is It Really?

In today's open thread for COTW, our 2010 Honda Insight EX, sealclubb3r asked, "How noisy is it really? I remember reading somewhere that it was much louder and less refined than a Prius. Is there as much interior noise as in y'alls 370Z?"

Well, here are a few excerpts from my personal notes when I drove a 2010 Honda Insight back-to-back with a 2010 Toyota Prius for a comparison test. I logged 400 highway miles in the Insight.

"Small gas engine isn't quiet, but it's fairly free-revving and not unpleasant to the ear... Insight has moderate wind noise, especially noticeable compared to the 2010 Prius, which doesn't have much at all... Insight has more road noise, but it's hardly what I'd call excessive."

But no need to rely on my possibly inaccurate notes -- I have actual decibel readings to back up my haphazard statements. Join me after the jump.

First, a qualifier: Due to extenuating circumstances on test day, we don't yet have decibel readings for the 2010 Prius. We'll get them for you, just not today.

So our 2010 Honda Insight is quieter than a 370Z. It's also a touch quieter at a 70-mph cruise than a 2009 Prius.

And it's quieter at full throttle than a Civic Hybrid -- probably because you don't have to work its engine as hard. The Insight takes 10.9 seconds to hit 60 mph and does the quarter-mile in 17.9 at 78.2 mph, versus a 13.5-second 0-60 and a 19.3-second quarter at 72.5 mph in the Civic Hybrid.

2010 Honda Insight
Db @ Idle: 44.2
Db @ Full Throttle: 72.5
Db @ 70 mph Cruise: 68.8

2009 Nissan 370Z
Db @ Idle: 47.4
Db @ Full Throttle: 83.1
Db @ 70 mph Cruise: 71.0

2009 Toyota Prius
Db @ Idle: 39.8
Db @ Full Throttle: 70.7
Db @ 70 mph Cruise: 69.7

2009 Honda Civic Hybrid
Db @ Idle: 45.9
Db @ Full Throttle: 76.0
Db @ 70 mph Cruise: 68.0
