Follow along with us at Lexus of Royal Oak as we outline the major differences between the regular Lexus RX 350 and the larger RX 350 L.

Cargo Capacity (behind 3rd-row seats) (L/cu-ft) 211 / 7.5

The primary difference between these two RX trims is seating ability, with the RX 350 L introducing a 3rd row that the base RX 350 doesn’t have. That means you can seat up to 7 people in the RX L (captain’s chairs for 6 or bench for 7) and only up to 5 on the RX. This also adds up to increased cargo capacity potential in the RX L behind each row of seats, so if it’s not just passengers you’re looking to drive but with a lot of luggage and gear as well, then the RX L is the perfect large SUV for you. An advantage that the RX 350 has, though, is a little bit more spaciousness in the headroom and legroom dimensions for its first and second/rear rows. The choice between the two boils down to how much passenger and cargo space do you truly need? Decide that and there’s an RX for you.

Dimensions: RX 350 RX 350 L
Length (mm/in) 4,880 / 192.1 5,000 / 196.8
Width (mm/in) 1,895 / 74.6 1,885 / 74.2

Wheelbase (mm/in) 2,789 / 109.8 2,789 / 109.8
Ground Clearance (mm/in) 208 / 8.2 206 / 8.1

To help make room for that extra row inside, the RX 350 L is a little bit bigger, as you would expect, but not incredibly so. This size comes from the extended length of the vehicle, whereas the other dimensions stay right around the same as the RX 350 presents. Both trims present the same bold and striking style, led forward by the signature Lexus mesh grille, LED headlights and a brawny stance that keeps the vehicle both intimidating yet sleek thanks to its aerodynamic modern SUV design. 18-inch wheels come standard, while 20-inch wheels are available on both for a more aggressive look.

Performance

Specifications RX 350 RX 350 L
Engine 3.5L V6 3.5L V6
Horsepower 295 292
Fuel Consumption (city/highway/combined) (L/100 km) 12.2 / 9.0 / 10.8 13.1 / 9.4 / 11.1

The engine performance differences are ever-so slight, but a change nonetheless between the two. While the RX L may be the champion when it comes to passenger and cargo capacity, if you’re looking for the best in engine power and efficiency, the 5-seat RX is for you. The RX 350 musters a bit more horsepower out of its engine at 295 than the RX 350 L can at 292. It’s not just in the power realm as well, but efficiency, too, with the RX 350 more considerate on gas given its smaller size, providing better fuel consumption rates on both the city and highway. If you want to maximize all you can out of the engine and performance side of the RX, the RX 350 is the option for you.
