How much does the Lexus RX 350 KERB weight?
The curb weight of a Lexus RX 350 varies by year and trim, but you can expect roughly 4,100–4,700 pounds depending on configuration.
In practical terms, curb weight (KERB weight) is the mass of the vehicle with standard equipment, fluids and a full tank, excluding passengers or cargo. For the RX 350, weight shifts with drivetrain (front-wheel drive vs all-wheel drive), wheel choice, and optional equipment, and changes across generations—from the traditional V6-powered models to the newer turbocharged setup available in newer generations.
What drives the weight variations across generations
Different model years and generations of the RX 350 use different powertrains and configurations, which significantly impact curb weight. The prior generation (roughly 2016–2022) used a 3.5L V6 with AWD or FWD; the current generation (2023 onward) shifted to a 2.4L turbo inline-4 paired with an electronic assist in some trims. Weight also increases with options like all-wheel drive, larger wheels, and premium interiors.
Typical ranges by drivetrain and generation
Below are approximate ranges for recent RX 350 models. Exact curb weight can vary by year, trim level, optional equipment, and whether the vehicle is front-drive or AWD. Use these figures as a guide and check the official window sticker or manufacturer's spec sheet for your exact vehicle.
- Front-wheel-drive (FWD) RX 350 (latest generations): roughly 4,100–4,350 pounds (1,860–1,975 kg).
- All-wheel-drive (AWD) RX 350 (latest generations): roughly 4,400–4,700 pounds (1,995–2,130 kg).
- Earlier V6 RX 350 models (pre-2023, with V6 and AWD/FWD): typically about 4,400–4,600 pounds (1,995–2,090 kg).
Note: These ranges reflect common configurations and may not cover limited editions or optional equipment that could push weight outside these bounds.
How to find the exact curb weight for your model
To determine the precise curb weight for a specific RX 350, check the following sources: the official Lexus brochure for the model year, the Monroney sticker on a new vehicle, or the technical specifications on Lexus.com. You can also consult the owner's manual or the vehicle's door jamb placard, which lists curb weight (Curb Wt) and gross vehicle weight rating (GVWR).
If you are shopping used or uncertain about the year
When buying used, verify the curb weight from the vehicle's VIN-based report or the dealer's spec sheet for the exact configuration, including whether it has optional equipment that could alter the weight.
In short, the RX 350's curb weight is not a single fixed number; it depends on year and drivetrain. For precise planning or payload calculations, confirm the exact curb weight for the specific model year and trim you’re considering.
Summary
The Lexus RX 350's curb weight varies with generation, drivetrain, and options, but you can expect roughly 4,100–4,700 pounds in contemporary models. FWD versions tend toward the lighter end, AWD adds heft, and updates to powertrains across generations also influence the scale. Always verify the exact curb weight from official sources or the vehicle's documentation for your specific configuration.
Summary: Curb weight is not a single fixed number for the RX 350; it depends on year and drivetrain, with typical values around 4.1–4.3k lb for FWD and 4.4–4.7k lb for AWD, and updated generations shifting weights due to drivetrain changes.
