I know it may be to soon to have the data but I wonder from the folks who already have their 50e, what mpg do they get on longer trips where you run out of the ev power and run ICE only? Given the extra weight the battery adds, I am curious how it impacts the mpg. Another question, once the battery is depleted, do you still get/feel any power boost from the electric engine? I had a Cayenne e-hybrid and even when battery was empty, it recharged itself enough to give quick boost when I needed the kick

Not a 50e, I have a '23 45e and just finished a 500mi trip this weekend. We averaged 26.7mpg over the whole trip, only charge was at the beginning.

And yes, there is always boost from the EV, it's never fully depleted. On road trips, I tend to drive in Sport mode, I've noticed a negligible difference in MPG.

Perfect! Thanks for sharing this

Also a 45e but my average is a little higher (~28 mpg) on highways in adaptive hybrid mode. That's with about 5000 highway miles with full fuel tank and battery charge at the start and no en route charging (other than regen).

IMHO, the only time you might run out of eboost or eassist (they're different) is if you were blasting up a long mountain grade after the battery was depleted. For normal operation, you likely won't notice any maximum performance issues. THe EV motor when used as an alternator can put a fair load on the ICE, but that also allows it to help maintain some useable battery capacity which is necessary for normal operations (all normal electronics are powered by 12vdc which is powered by a DC-DC power supply, supplied by the HVB) along with all HVAC functions.

FWIW, I, too, got about 28-mpg on a long trip with little opportunity to recharge (about 2000-miles) in the summer with the vehicle at full load. Road speeds were mid-70's, so nothing extreme. Once you're up to speed, the weight doesn't really make a huge difference so a long cruise is similar to the ICE although it can be more efficient at cruise, just not in stop and go.

After 1800 miles, since factory its 27.4 mpg. Peak 2 hour 75 mph interstate was 30.4 mpg. All on either Sport or Battery Hold.

[Flying Ace]

my 45e returns about 26-28 mpgs. Just remember the longer you go without charging on a road trip, your MPGs will trends towards the 24-28 mpg level. The way to calculate is the relative % of no fuel driving on EV vs on gas for that distance. Also note regen and coasting will add to the mpg estimate.

[mopaman]

45e as well. I get about the same 25-28 mpg starting with a full battery, over about a 380 mile 6 hr drive. If you go faster, up to 85-90+ mph, it drops rapidly to 20 mpg or so, esp if you start with less battery charge.

[jad03060]

80-mph versus 75-mph, drag is approximately related to the square of the speed, so 80^2/75^2, one would expect at least a 13.7% decrease in efficiency. Going faster may get you there faster, but not if it incurs additional stops for fuel or energy.

I am getting close to 50 miles on a full charge on electric, have not filled the tank since we got the car three weeks ago I too am curious to see how far it can go on Hybrid with a full tank and charge. Looking forward tot he first hockey tournament road trip using the Auto Plus to drive the highway to Pitt/Phili :-)

[nZtiZia]

same with my 45e… between 26-28mpg at highway speeds (70s) mainly in Hybrid drive mode

as mentioned, even after the usable capacity is depleted (I don’t like to say “battery depleted” because there is usable versus gross capacity), the vehicle will use the ICE to recharge the HV battery to a certain minimum level depending on which mode you’re driving in

[David3]

I drove my 50e 1700 miles home from factory. Best was about 30 mpg on final 500 miles leg. Average about 28, if memory serves

Just did a 5 hour trip - averaged about 28.5 mpg. No sport mode, but curvy, hilly route for some of it. Used ICE for the long highway slogs where it shines (75-80 mph), electric mode when at destination and running around.

[DCHS]

Yesterday, on a 122 mile trip, obtained 25.4 mpg running on Sport mode only, battery stayed at around 4 miles. Trip was approx 60 mi freeway at 77mph, 45 mi of 45-55mph back roads and 17 mi city driving. FWIW.

[mscot]

Why would the battery deplete if you're just driving in hybrid mode?
Shouldn't it regen just like a regular hybrid?
The battery in our Rav4 hybrid never depletes, its always in hybrid mode.

So if I take a roadtrip in an X5 PHEV and I'm in hybrid mode the entire time, would the battery actually deplete so I'm only in ICE mode?

[RetSurfer]

Just got off a 1,200-mile trip to Florida.

Battery hold on the way down, Sport mode while there, and Hybrid on the 500-mile return, no Battery Hold, though only 7 miles left.

28.9 mpg….

[apw2607]

I have some data. 50e

177 miles. MPG=37.2 mpg. I held about 50% capacity of the battery for return journey

The default mode is hybrid...the computer will decide whether running the ICE or the electric motor is more efficient. As a result, yes, the batteries can end up depleted. If you want to retain some battery capacity, you need to engage battery hold at your desired set point. Unlike the 45e, it cannot directly recover, but it will hold until you shut the vehicle off...then it resets.

A plug-in hybrid is not the same as a mild hybrid.

Thanks. I'm flabbergasted why they wouldn't build the 50e so that it can regenerate with the breaks or on downhills like a normal hybrid can.
Can you set it so that the battery is always held to a certain level when in hybrid mode?

It does regenerate and you can hold the battery level.

[jad03060]

Most modes do utilize regeneration, and someone who was out west, indicated while going up, their battery was nearly depleted, but it was nearly full after coming down the other side. Some modes tend to coast, though, until you press the brake. Note, braking on the X5 PHEVs is electronically controlled...the computer decides whether regeneration or physical hydraulic use in the brakes is required. There is a bypass to enable hydraulic mode if the computer fails, though. While driving it, it's fairly easy to see when it is regenerating, and there's a screen you can put up that shows it on the center iDrive display, if that interests you.

[mlurker]

I have 45e. On a long trips I set the battery hold mode to 90% and keep it until I reach a destination.

Last weekend I had a 200 miles trip with speeds of about 75 mph, car was showing 28 mpg, used about 40% of the battery for the trip.
