2019 Lexus LX 570 front quarter

In the Lexus lineup, no vehicle is larger — or older ⁠— than the LX 570, a true luxo barge if there ever was one. Riding atop a platform shared with the Toyota Land Cruiser and Tundra, the current body-on-frame LX 570 appeared in the spring of 2007, going on sale later that year as a 2008 model.

A redesign isn’t expected for another few years, making this model generation longer-lived than most marriages. And yet a clue exists of a new LX to come — one that scraps the LX 570 name for a loftier number.

A U.S. trademark filing spotted by Autoguide reveals Lexus has a new model in mind: LX 600.

Such filings tell us nothing about the vehicle except to point out whether a name is indeed bound for the exterior of a vehicle, which this one certainly is.

While the current model name denotes the presence of a 5.7-liter V8 that’s carried the model for many years, the LX600 name can be taken two ways. Either Toyota has a larger displacement in mind for the model’s eight-banger, or it plans to do away with naming convention and lend the “600” designation to a lower-displacement engine with more power than the old mill.

Despite putting out 383 horsepower and 403 lb-ft of torque, the LX’s acceleration is hampered by a prodigious curb weight born of its ancient platform. While fine for cruising and getting up to highway speed in normal driving, it’s not as fleet of foot as some rivals.

Lexus is said to have a number of new big-vehicle powerplants under development, including a twin-turbo V8 of considerable less displacement than 5.7 liters, as well as a hybrid V6 bound for the next Tundra. Given that the trademark filing is for LX 600 and not LX 600h, it’s safe to assume an upcoming LX will offer the larger of these engines.

As for when it will appear, that’s another mystery. Some reports have placed the new Tundra’s introduction as early as the 2021 model year; Automotive News’ Product Pipeline, however, cites an intro date of 2023 for the next LX, which borrows the Tundra’s new, lighter weight platform. Of course, engine upgrades don’t have to coincide with a bottom-up revamp.

    Make it the truck version of the Toyota Century.

    Will it get a larger grille? Because, you know, it matters…

    If Toyota really wanted to cement the Land Cruiser/LX’s position as the ultimate off-road vehicle, it would develop a hybrid system with relatively powerful front and rear electric motors that are both set up to do torque vectoring. But that would be expensive to develop and I doubt it would be worth it for relatively low volume.

    I’m guessing 4L TTV8.

    Toyota has needed new V8 tech for some time now.

      I wish they would give us the 4.5 tt diesel that Aussie’s get. It’s a perfect fit for this vehicle. Powerful and far more fuel efficient than the gasser

        Americans are so skittish on foreign diesels.

          And why shouldn’t they be, given the stellar reputation of gems like the FCA 3.0 Ecodiesel, or the VW mess etc.

          Diesel doesn’t make sense in anything but HD trucks. Its advantages in running costs have been more than made up for in higher maintenance, higher per gallon fuel costs, DEF and so on.

          The target market for a $100,000 luxury SUV wants nothing to do with a dirty truck stop fuel pump handle or adding DEF every 5000 miles. They couldn’t care less about 2-3 more mpg. No one is taking these things across the outback. A big lazy V8 is perfect for this truck and I hope that’s whats kept.

            I mostly agree with you, though it’s not quite like you have to go to a truck stop to get diesel. Many regular gas stations have it.

            True but I bet it’s less than 50% of non truck stop stations around me that carry it. It’s undeniably less convenient than gas, and the upsides just can’t cancel out the negatives.

            Modern diesels are great. My wife has a new 2018 Skoda Octavia Combi vRS 2.0 TDI and the Adblue tank requires a refill roughly every 16,000 km depending on how aggressive you drive. It is not inconvenient at all because now it is quick and easy to refill the tank at gas stations.

            DPFs are reliable and effective as long as you allow the engine to warm up and avoid short trips. Consistently doing short trips can lead to the DPFs clogging because they do not reach their operating temperature and thus do not regenerate.

            Regarding diesels in SUVs, I prefer them over gasoline engines. My 2007 Mercedes GL320 CDI 4Matic can be driven flat out at high speeds on the Autobahn while returning impressive fuel economy. Impressive fuel economy considering the weight and the poor aerodynamics of this old SUV. The good fuel mileage also translates into better/longer range and thus more time spent behind the wheel during long trips, which I frequently do.

      I think given the fuel economy gains, it’s well worth it. Haven been in one before, I saw 23 MPG average in pretty mixed driving in the land down under. And thats the twin turbo model. They also make a version of this engine with a single turbo and while less powerful, its gets far better fuel economy. Its a well proven engine too. Lots of the police/military have them as vehicles and they stand up really well to abuse. If people did not care about luxury diesels, how are there so many q7 tdi’s or gl350bt’s around? Obviously there is a market for them. Given the recent departure of these models, I would think this would be a prime opportunity to bring one to market. At the very least it would give it something to stand out in its class as very few care about the off road ability. They mainly are in it for 200K+ trouble free miles.

        The calculations are different in countries where diesel is less expensive than gas, and 87 octane isn’t $2.50 a gallon. Here it’s pretty consistently 20% or more higher for diesel. Running cost advantages are basically nil, and even if there was one, it’s irrelevant to the owner of a $100k truck. Fuel is such a minor part of the ownership cost of such a vehicle that there’s really no reason to bother with the hassle of diesel.

        As for the diesel versions of the German SUVs, they aren’t sold in this country anymore. Which seems to prove my point that diesel doesn’t make sense in this market unless you need heavy towing all the time.

    Tundra is unrelated, it shares its platform with the Sequoia. GX460/Land Cruiser Prado, 4Runner, Tacoma and Hilux are all related. LX570 and Land Cruiser are separate platform.

      It’s a separate platform but it shares quite a few parts. You’d be surprised how many things can be swapped between a current-gen Tundra and a 200-series Land Cruiser or LX. Nothing in the suspension, but pretty much everything powertrain-related.

      Tacoma and 4Runner don’t share a frame. 4Runner frame is fully boxed and Tacoma is C Channel. 4Runner shares a frame with Prado and GX.

    Looks like crap. Nothing luxury about it. Why Toyota even needs this monster? Isn’t Land Cruiser enough? Have no illusions, Toyota is not Land Rover.

    That thing is simply ridiculous looking.

    You guys, you accidentally used a pic of one that was in a horrible head-on collision.

    Oh wait, it’s supposed to look like that?
