Anyone here know when/if a GX hybrid will come out? I cant buy the current model that only gets 20 mpg. Thanks.

 

Sorry to burst your bubble, but none of the current Toyota/Lexus hybrid systems in the truck/large SUVs are intended to improve mileage much more than just a few numbers in the city, and show little to no improvement on the highway.

The hybrid systems in these vehicles are intended to improve acceleration/torque.

The 4-cylinder turbo-hybrid in the new Landcruiser/4Runner hybrid platform has not shown overly impressive mileage numbers vs the turbo 4-cylinder only drivetrain.

Also, in real world observations, many people driving the new Landcruisers with the hybrid setup aren’t seeing much better than 16mpg average around town, which is about what a GX550 can do. It comes down to physics and the minimum power required to move a 5600lb SUV. Toyota would need a 150-200hp electric motor System to make a hybrid that was capable of the primary drive and not just an assist system above 18mph.

If the GX550 hybrid includes the same system as the Landcruiser/4Runner, that will be a disappointment at the price point these will likely list for as the engines are a bit less unrefined than the v6. If they do a hybrid 3.4L like in thre Tundra and Sequoia platforms, it will be a real runner with a lot of zip but it won’t improve the mileage enough to worry about.

Personally, I would just add a good tune for 60hp more at the wheels and keep the complication of the hybrid system out of this already complicated drivetrain.

 

I'm guessing they may go the route of the hybrid 3.4 as in the new LX700, to differentiate the hybrid systems between the GX & Land Cruiser.

 

Good to know thanks. Any changes we know about from 2025 to 2026 models yet? This whole
process kind of sucks right now because my local lexus dealer doesn’t even have them in to test drive

 

Best I've had in my OT+ is 17.9 mpg.

Twin turbo V6 in a body on frame heavy SUV does not equal a gas sipper.

A hybrid battery in an already kind-of small truck ruins storage space - especially when combined with a 3rd row seating option.
Go check out the rear area of the new Sequoia.

The boxy shape with an almost vertical windshield means highway mileage is not much better than
mixed driving around town. I got 16.0 mpg last highway trip with a head wind.

 

The fuel economy for the 4Runner and the Land Cruser with i-force max hybrid are both something like 23mpg - of course MPG may vary, and will likely be less than that. That said, 23, even if not great, is a lot better than the 16pmg or so in the GX460. So if you anchor back to the old model as your reference point then you can tell yourself that you are getting great fuel economy

 

3K miles on mine. Lifetime average MPG is 12.1. 98% city driving which in Orlando is like rush hour all the time; lots of sitting. I did one 2 hour highway trip (why it's 12.1 vs the 12.0 when I started) and looks like it will get 20+ at 70mph. Running 75-80 it was consistently showing under 20mpg. It's worse than my GX460 or 470. My wife is the primary driver and drives like my grandmother.

Settings are eco/comfort, luxury +.

Frankly, hate the car. Worst and probably the last Lexus I'll buy.

 

Does the tune void the factory warranty?
Can this tune be done at a dealer?

 

Curious what Lexus marketing has up their sleeve on naming it….GX550h…GX340h…GX680h….GX500h

 

I have achieved 20-21+ mpg on the road in my 23 GX460 without a problem and I like the size of this rig for parking purposes as well.
The only other choice I would consider is the LX700h OT or the older LC200.

 

Gas mileage is improving at 5,000 miles. 18.5 - 19.0 mpg last 3 tanks.
