Lexus TX: which version to buy

The Lexus TX has one generation, on sale from June 2023 with no end date in the data, as an SUV 5-doors with four versions.

The Lexus TX has one generation, on sale from June 2023 with no end date in the data, as an SUV 5-doors with four versions. The choice is not “which generation” — there is only the 1 generation — but which of TX 2.4 350, TX 2.4 350 AWD, TX 2.4 500h, and TX 3.5 550h+ matches the numbers you actually need: 279 hp versus 366 hp versus 404 hp, FWD versus AWD, Automatic versus Variable, and, on one version only, measured 0–100, mpg-style consumption, weight, tank, and ground clearance.

Generations: what changed (one generation, four versions)

1 generation (from 2023-06-01, still current) is the whole story: SUV 5-doors, four versions, no restyling listed as a separate generation. Every version starts on the same date. Chassis language is the same across the range: Independent, spring at the front; Semi-independent, springorts hélicoïdaux, sem at the rear; Ventilated disc front brakes; Disc rear brakes. Engine placement is Front, longitudinal on all four. Fuel is 95 on all four. Boost is Turbo on all four. Valves per cylinder are 4 on all four.

What the generation does not change between versions is the body and that shared hardware list. What it does change is powertrain: two Gasoline inline-4 turbos at 279 hp, one Hybrid inline-4 turbo at 366 hp, and one Hybrid V-shaped 6 at 404 hp; FWD on one car, AWD on three; 8-speed Automatic on the Gasoline pair, 6-speed Automatic on TX 2.4 500h, Variable on TX 3.5 550h+.

Specs and engine: the four versions side by side

TX 2.4 350 and TX 2.4 350 AWD share 279 hp, 205 kW, 430 Nm, Turbo, 4 Inline, compression 11, bore × stroke 87.5 x 99.5, Automatic with 8 gears. The data split them on drive (FWD vs AWD) and on displacement (2393 cc vs 2400 cc — 7 cc as recorded). Power per litre: 279 / 2.393 ≈ 116.6 hp/l on TX 2.4 350; 279 / 2.400 = 116.3 hp/l on TX 2.4 350 AWD. They are the same power class; AWD is the arithmetic difference that matters.

TX 2.4 500h keeps 2393 cc, 4 Inline, Turbo, compression 11, 87.5 x 99.5, and 95, but is Hybrid with Combined injection (direct-distributed). Output is 366 hp — 87 hp more than either 350 — and 550 Nm — 120 Nm more than 430. Power per litre: 366 / 2.393 ≈ 152.9 hp/l, the densest of the four. Peak torque is the only one with an rpm window (2000–3600). Gearbox is Automatic with 6 gears, not 8. Drive is AWD.

TX 3.5 550h+ is the only 6-cylinder, V-shaped, 3456 cc Hybrid. Power is 404 hp — 125 hp more than the 350 pair and 38 hp more than TX 2.4 500h. Power per litre: 404 / 3.456 ≈ 116.9 hp/l, almost the same specific output as the Gasoline 2.4s, so the extra horsepower is mostly extra displacement (3456 − 2393 = 1063 cc vs TX 2.4 350 / TX 2.4 500h; 3456 − 2400 = 1056 cc vs TX 2.4 350 AWD). Torque is not measured. Gearbox is Variable. Drive is AWD. Compression, bore × stroke, and injection system are not measured.

Performance, mpg, and economy: only one version is measured

0–100, top speed, and consumption are not measured on TX 2.4 350, TX 2.4 350 AWD, and TX 3.5 550h+. Do not treat those blanks as “no such parameter.” They are unmeasured in this dataset.

The only measured sprint and economy sit on TX 2.4 500h: 0–100 in 6.1 s, top speed 180, city 8.7, highway 8.4, mixed 8.7, tank 65. That is the version you can compare to a number rather than to a gap. Mixed and city are the same figure (8.7); highway is 0.3 lower. You cannot rank TX 3.5 550h+ as “faster” than TX 2.4 500h on 0–100: 404 hp vs 366 hp is 38 hp, but 0–100 for 550h+ is not measured. You cannot rank the 350 pair on fuel either.

Dimensions, weight, and ground clearance

Kerb weight, gross weight, ground clearance, tank, and wheels are not measured on TX 2.4 350, TX 2.4 350 AWD, and TX 3.5 550h+. Wheel sizes are not measured on any version.

On TX 2.4 500h: kerb 2254, gross 2864, ground clearance 203, tank 65. Payload from those two masses: 2864 − 2254 = 610. Weight per horsepower: 2254 / 366 ≈ 6.16 kg/hp. You cannot compute kg/hp for the other three because kerb is not measured. You cannot say the Gasoline FWD is lighter; the data do not give its mass.

Which version to choose

Choose TX 2.4 350 if the brief is FWD and the 279 hp Gasoline turbo. It is the only FWD. Same 279 hp / 430 Nm / Automatic 8 / Turbo / 4 Inline as the AWD Gasoline sibling, on 2393 cc. You give up AWD. 0–100, top speed, consumption, tank, weights, clearance: not measured. Buy this when the data’s only unique claim — Front-wheel drive — is what you want, not when you need a measured sprint or mpg figure.

Choose TX 2.4 350 AWD if you want that same 279 hp / 430 Nm Gasoline package with AWD. Versus TX 2.4 350 the recorded extras are AWD and 2400 cc instead of 2393. Versus either hybrid you give up 87 hp (TX 2.4 500h) or 125 hp (TX 3.5 550h+) and Hybrid labelling. Gearbox stays Automatic 8. Performance, economy, mass, tank, clearance: not measured. This is the “same engine class, add AWD” pick, not a power upgrade.

Choose TX 2.4 500h if you need the only fully measured car and the strongest 2.4. Versus TX 2.4 350 AWD you gain Hybrid, Combined injection (direct-distributed), 87 hp, 120 Nm, AWD (already on 350 AWD), a 6-speed Automatic instead of 8, and the only 6.1 s / 180 / 8.7–8.4–8.7 / 65 / 2254 / 2864 / 203 set in the catalogue. Versus TX 3.5 550h+ you have 38 hp less and 4 Inline vs 6 V-shaped, but you have torque (550 vs not measured), a 6-speed Automatic vs Variable, and every performance and mass number the 550h+ lacks. Specific output (~152.9 hp/l) is the highest of the four. If the question is “which version can I actually size on paper,” this is the answer.

Choose TX 3.5 550h+ if peak listed power is the criterion. 404 hp is the top of the 1 generation: 38 hp above TX 2.4 500h, 125 hp above both 350s. It is the only 3456 cc, only 6, only V-shaped, only Variable. Drive is AWD, same as 500h and 350 AWD. Torque, 0–100, top speed, consumption, tank, weights, clearance, compression, bore × stroke, injection: not measured. Specific output (~116.9 hp/l) matches the Gasoline 2.4s, not the 500h. You are buying displacement and the highest hp figure, not a documented quicker 0–100 or lower mixed figure.

Short ranking on what is actually in the data. Most power: TX 3.5 550h+ (404). Most power per litre and only measured 0–100 / mpg / weight: TX 2.4 500h (366 hp, 6.1 s, mixed 8.7, 2254 kg). Same 279 hp Gasoline, FWD vs AWD: TX 2.4 350 vs TX 2.4 350 AWD. Only FWD: TX 2.4 350. Only Variable: TX 3.5 550h+. Only Combined injection (direct-distributed) listed: TX 2.4 500h. Reliability, problems, and prices are not in this dataset — they are not measured here, so they cannot decide the version.
