Hybrid tech coming for the big Hondas.

While the Honda Pilot and especially the Passport are fairly new, their V6 powertrain isn’t. It is still one of the smoothest engines around at any price, but gas mileage is a big issue. In my recent test drive of the new Honda Passport, I wasn’t able to get over 23MPG on the freeway. Which is 2025 is unacceptable. especially for a V6 engine, not a huge 6.2 Liter V8.

It looks like Honda is finally almost ready to introduce a fix. That fix will be a hybrid system for their larger vehicle. Basically, all the ones that are currently using the 3.5 Liter V6. Like The Passport, Pilot, Odysseya, and Ridgeline. This will obviously be a different system from the new one that will be used in the next-generation Honda Civic late next year. And the next Accord later. That system will use an improved 2-liter 4-cylinder system and will shave up to 200 pounds off this car’s weight.

The new large V6 system is probably using a version of Honda’s most recent 3.0 Liter V6 that is used in the Acura MDX T-Type. The electric motor and the battery pack will also be new. Acceleration is said to be improved by 10%. But the main goal of this is to improve the disastrous fuel economy by 30%. Which would bring the Passport to around 30MPG in real-life FWY driving. Noting earth-shattering, but a big improvement. (OF course, EPA numbers will be even higher). Unless that improvement is mostly around town. Which could mean going from the current 16MPG (observed in my test drive) to around 20MPG. Which is just OK.

To me, that all seems a lot of work for an improvement that might not be worth it. It seems people who buy these big SUVs, Minivans, and trucks don’t really care about MPG. Would 16MPG to 20 MPG really bring sales up? The big Pilot had one of its best years ever last year, with over 141,000 units sold. That’s obviously 1421,000 buyers who don’t care about fuel economy.

The new V6 hybrid powertrain is scheduled to be introduced for the 2027 model year. This will match a mid-cycle facelift for the Honda Pilot. The Passport could get it later. And who really knows what’s going on with the old Odyssey and Ridgeline? These are both long overdue for a new generation.

The illustration above shows what a new generation of the Honda Passport could look like. One with, of course, the new V6 Hybrid.

  1. I believe Honda meant the engine’s performance alone would be a 20% improvement – not including gains from the electric motors. They will target 30+mpg combined. A 3.0L atkinson cycle engine would certainly be a good option for a hybrid. The 3.0L twin scroll turbo engine’s (from the Acura TLX/MDX TypeS) structure was significantly more rigid to handle the higher compression pressures and cooling requirements of the turbo… and therefore more expensive too. If Honda was to use the 3.0L’s block, I could see it being altered quite a bit for hybrid duty (ie. lighter). Therefore, they may choose instead to make another iteration to the current J35 V6 from the Pilot/Passport/Odyssey. Either may require a different solution to the current single-drive gear for highway cruising in engine-only mode of the 2-motor hybrid configuration. The V6 might need 2 gears to keep revs lower at higher speed and boost fuel economy. Likely, either choice will come down not just to efficiency but also packaging, in order to fit the clutch packs and electric motors in with the larger engine.

  2. I routinely get 29-31 mpg highway on my Odyssey at 70-75 mph… 23 mpg seems like an excessively big drop for small additional weight of a Passport.
