new ride: accord v6 with VCM

[2.Slow]

Got rid of a fuel-inefficient Jetta, and picked up a 2012 accord v6 with the variable cylinder management. I'm looking forward to seeing what numbers I can post. It's rated at 20 city, 29 hwy.

Anybody else have this type of engine (not necessarily v6, but any of the i-vtecs)?

Need to raise the psi immediately, Honda prefers 32psi, going to bump that up to about 40psi.

We just got a 2012 Civic (manual trans), and it came from the dealer with 40psi in the tires. I was amazed! It was getting great mileage, but I thought I would try bumping that up to the sidewall max of 44 psi. It didn't improve the mileage any, and doesn't seem to coast any further (no scientific testing, just using on the on-dash fuel meters & speedo), ride is only a tiny bit more harsh than at 40psi but handling is a little worse. I'm going to switch back to 40 psi.

Pain in the arse to keep the cylinders deactivated... requires a veeeeery light foot... but if you can do it, I've seen people get up to 42 mpg by keeping the "ECO" light and the VCM light lit.

But that was at a steady 50-55. Don't know what you can expect at your standard 60 mph...

Two words: Cruise Control.

Here's a trip we took last weekend, 288 miles round trip, cruise control set at 65mph the whole way. The southern half is pretty hilly, but northern half is almost flat. Built-in gauge showed 40.3 mpg, miles divided by gallons was 40.38 mpg. I think on pure flat roads, using cruise control at 65 mph would yield 45+ mpg.

Here's the elevation changes:

Thanks for the feedback. Yeah, I'm going to finally hook up my scangauge tomorrow to see what the vehicle is capable of.

Looks like the V6 is capable of shutting down 3 cylinders, which I can easily see printing 40+.

The biggest issue I have right now is the fact that it's a FAST honda, which seems like an oxymoron and leads to a non-hypermiling foot!

Too fast for a boat. Wish they'd Mugenize the suspension...

Was that two way?

There's a specific load point at which the cylinders deactivate. Don't know if you can maintain 65 at that load point, but then, I've not driven the car extensively...
