Lexus RZ

Which Lexus RZ Version Should You Buy?

The Lexus RZ choice depends chiefly on whether you prioritize lower kerb weight, FWD simplicity, or maximum AWD performance. Among the original versions, AT 300e is the least powerful at 204 hp, while AT 550e F Sport leads with 408 hp and the quickest measured 0–100 km/h time of 4.4 seconds. The restyled range introduced in March 2025 retains 350e, 450e, and 550e F Sport.

The restyled range introduced in March 2025 retains 350e, 450e, and 550e F Sport. The database contains no prices, range figures, dimensions, or reliability data, so those factors cannot be used to recommend one version over another.

Lexus RZ generations and version changes

The Lexus RZ has one generation represented in two stages. The original first generation began in April 2022 as an SUV Coupe and contains five versions: AT 450e, AT 300e, AT 350e, AT 500e, and AT 550e F Sport.

The restyling began in March 2025 and is listed as an SUV 5-doors. It contains three versions: 450e, 550e F Sport, and 350e. Compared with the earlier selection, the restyled range no longer lists AT 300e or AT 500e. The 350e remains a 224 hp FWD version, the 450e remains a 313 hp AWD version, and the 550e F Sport remains a 408 hp AWD version. These specifications show continuity in the core hierarchy, but the data does not describe any styling, equipment, battery, range, or price changes.

Lexus RZ engine options and specs

Every listed Lexus RZ version uses an Electro powertrain, an Automatic gearbox with 1 gear, and no stated displacement. Cylinder count, cylinder layout, and boost are also not measured, so an engine-size or power-per-litre comparison cannot be calculated.

For the original range, AT 350e provides 20 hp more than AT 300e while retaining the same measured 265 Nm. Moving from AT 350e to AT 450e adds 89 hp and 170 Nm, as well as changing from FWD to AWD. AT 500e adds another 67 hp over AT 450e but has the same measured 435 Nm. AT 550e F Sport produces 28 hp more than AT 500e, although its torque is not measured.

In the restyled selection, 450e has 89 hp more than 350e and changes the drive system from FWD to AWD. The restyled 550e F Sport adds 95 hp over 450e. Torque cannot be compared across all three restyled versions because it is measured only for 350e, at 269 Nm.

Lexus RZ performance, mpg, and economy

The original AT 350e reaches 100 km/h 0.5 seconds sooner than AT 300e. AT 450e is another 1.9 seconds quicker than AT 350e. AT 500e cuts 1 second from the AT 450e result, while AT 550e F Sport improves on AT 500e by 0.2 seconds.

The restyled 550e F Sport is 3.1 seconds quicker to 100 km/h than the restyled 350e. Its 4.4-second result is unchanged from the measured figure for the earlier AT 550e F Sport, while the restyled 350e retains the earlier AT 350e figure of 7.5 seconds. Acceleration for the restyled 450e is not measured.

The data provides no MPGe figure and no city or highway consumption measurement for any version. Combined consumption is not measured except for the restyled 350e, where it is listed as 14.4. The unit is not supplied, so the figure should not be treated as mpg or MPGe. Driving range is not measured for any Lexus RZ version.

Lexus RZ dimensions, weight, and wheels

Exterior length, width, height, wheelbase, and other dimensions are not measured for any listed version. Ground clearance and tank capacity are also not measured throughout the range.

AT 350e is the lightest original version at 1,995 kg. It is 80 kg lighter than AT 300e, despite producing 20 hp more. AT 550e F Sport weighs 2,135 kg, making it 20 kg lighter than AT 500e and 40 kg lighter than AT 450e while also producing more power than either.

Calculated from the supplied kerb weights and power outputs, AT 300e carries approximately 10.17 kg per horsepower. AT 350e improves that figure to approximately 8.91 kg per horsepower, AT 450e to approximately 6.95, AT 500e to approximately 5.67, and AT 550e F Sport to approximately 5.23. Among the original versions, AT 550e F Sport therefore has the strongest power-to-weight relationship.

The restyled 350e weighs 2,050 kg, which is 55 kg more than the earlier AT 350e. At the same 224 hp, its calculated weight per horsepower changes from approximately 8.91 to approximately 9.15 kg. Weight figures for the restyled 450e and 550e F Sport are not measured, so equivalent calculations are unavailable.

All versions use Independent, spring suspension at the front and rear. Every version also has Ventilated disc front brakes and Disc rear brakes.

Which Lexus RZ version should you choose?

Choose AT 350e from the original range if you want the best numerical case among the lower-powered FWD versions. It has 224 hp, matching the power of the restyled 350e, but its 1,995 kg kerb weight is 55 kg lower. It also beats AT 300e by 20 hp, accelerates to 100 km/h 0.5 seconds sooner, and weighs 80 kg less. Its gross weight and top speed are not measured.

Choose AT 450e if AWD and measured torque matter more than minimum weight. Its 313 hp output exceeds AT 350e by 89 hp, while its 435 Nm exceeds the AT 350e figure by 170 Nm. Its 5.6-second acceleration time is 1.9 seconds quicker, although its 2,175 kg kerb weight is 180 kg higher.

Choose AT 500e when you want near-leading performance but need the most complete recorded wheel information. It produces 380 hp, reaches 100 km/h in 4.6 seconds, and is the only version with measured wheel sizes: 235/60 R18 and 235/50 R20. AT 550e F Sport is 28 hp stronger, 20 kg lighter, and 0.2 seconds quicker, so the supplied numbers favor AT 550e F Sport for outright performance.

Choose AT 550e F Sport—or the restyled 550e F Sport—if acceleration and power are the priorities. Both deliver 408 hp and a measured 4.4-second 0–100 km/h time. The earlier AT 550e F Sport has a measured 2,135 kg kerb weight, while weight for the restyled 550e F Sport is not measured. No price figures are available, so the extra cost or value of either version cannot be assessed.

Choose the restyled 350e if you specifically want the SUV 5-doors stage and FWD. It has 224 hp, 269 Nm, a 7.5-second 0–100 km/h time, a 2,050 kg kerb weight, and a 2,520 kg gross weight. Compared with the earlier AT 350e, it has the same power and acceleration, 4 Nm more measured torque, and 55 kg more kerb weight.

The restyled 450e is the least conclusive choice from the available specifications. It provides 313 hp, AWD, an Automatic gearbox with 1 gear, Independent, spring suspension, Ventilated disc front brakes, and Disc rear brakes. However, its torque, acceleration, top speed, consumption, weights, ground clearance, tank capacity, and wheel sizes are not measured. Buyers comparing it with the earlier AT 450e should therefore avoid assuming that their performance or weight figures are identical.
