Towing & payload

The L322 is one of the great tow cars: a heavy, grippy, torque-rich 4x4 rated to pull up to 3,500 kg. For horseboxes, caravans and trailers, a diesel L322 is hard to beat, which is exactly why so many were bought for the job. This page covers the towing limits, the often-missed noseweight rules, payload, weight distribution hitches and how to hitch up correctly with air suspension.

Towing limits

The headline figure is 3,500 kg, but the full picture has several limits that all matter. The most useful way to read them is together, because the lowest applicable limit is the one you must not exceed.

Petrol cars are sometimes plated lower than diesels for braked trailers. Always check the exact plated towing and noseweight limits for the specific car and market, since these vary by year, engine and region.

Noseweight: the limit owners miss

The L322's noseweight (the download the trailer puts on the towball) is limited to 250 kg, and only 150 kg when the car is loaded to its gross vehicle weight. This is lower than many rivals: most other full-size Land Rover products allow 350 kg. The reason is the L322's monocoque body, where an add-on tow bar cannot carry as much download as an integral one.

In practice 250 kg is plenty for most trailers, since the common guideline is a noseweight of around 7 to 10 percent of the trailer weight. A 2,500 kg caravan at 10 percent is 250 kg, right at the limit, so heavier trailers need loading carefully to keep weight off the nose. If you regularly tow near the maximum, load the trailer so its balance keeps noseweight within limits rather than relying on the car to cope.

Why it's a great tow car

• Big low-down torque. The TDV8?TDV8: Land Rover's twin-turbo diesel V8 (3.6, later 4.4), the 'AJD-V8' / 'Lion' engine, prized for huge torque. diesels pull from very low revs.
• Heavy, planted kerb weight?kerb weight: The weight of the car ready to drive (fluids, no occupants or luggage). The L322 is heavy at ~2.4-2.8 tonnes. gives stability with a trailer.
• Permanent 4WD + low range for slippery launches (wet fields, ramps).
• Air suspension self-levels for noseweight, keeping the car composed.
• Supercharged/TDV8 cars add an electronic rear diff for traction.

Best engine for towing

Payload

Payload is what the car itself can carry (people plus luggage), separate from what it can tow. The L322's payload is modest for its size, typically around 480 to 650 kg depending on engine and spec, because the car is already heavy before you load it. With a full tank, a family and luggage you can be close to the limit, so a roof or rear load on top of a full car needs thought. Overloading the rear is one way to strain or fault the air suspension.

Weight distribution hitches

A weight distribution hitch (WDH) spreads trailer noseweight across both axles using tensioned bars. With the L322 the picture is mixed. The L322's tow receiver is solid and integral to the body, unlike the Discovery 3/4 and Range Rover Sport where the casting has been known to fail, so the L322 is structurally better suited to towing. However, a WDH works against the car's self-levelling air suspension, which keeps adjusting to counter the bars.

Many owners tow without a WDH because the air suspension already levels the car. If you do use one, it must be set up correctly with the suspension prevented from levelling during setup, as described below. For most owners within the noseweight limit, the air suspension alone keeps the car level and composed.

Hitching up with air suspension

The L322 levels itself when you load the towball, which is helpful, but it can fight you during hitching and WDH setup because it keeps adjusting. The trick is to stop it levelling while you connect.

• Stop the levelling. With the engine off the system cannot pump up. Opening a door also suspends levelling on later cars, which is a simple way to hold height.
• Connect on level ground. Park level, drop the trailer onto the ball with the engine off, set any WDH bars, then start the car and let it level normally.
• Watch reservoir pressure. Some cars can still raise with the engine off if the reservoir has pressure, so use the door-open method to be sure it holds.
• Let it settle. Once running, the car levels for the noseweight and holds the set height, keeping the headlights and ride correct.

Towing tips

Because towing accelerates wear, a car with a tow history needs an especially careful look at the gearbox, transfer case, brakes and air suspension. See the buying guide and common problems before buying an ex-tow car.

Frequently asked questions

How much can a Range Rover L322 tow?
Up to 3,500 kg for a braked trailer and 750 kg unbraked. The diesel TDV8 cars are the strongest and most relaxed tow vehicles in the range.

What is the L322 noseweight limit?
250 kg maximum, reduced to 150 kg when the car is loaded to its gross vehicle weight. This is lower than many full-size SUVs because of the monocoque body, so balance heavy trailers to keep weight off the nose.

Which L322 engine is best for towing?
The 4.4 TDV8 with 700 Nm is the best, followed by the 3.6 TDV8 with 640 Nm. Both pull heavy trailers effortlessly. Petrol V8s tow well but use a lot of fuel under load.

Can I use a weight distribution hitch on an L322?
You can, but it works against the self-levelling air suspension. Many owners tow without one because the air system already levels the car. If you fit a WDH, set it up with the suspension prevented from levelling.

Does towing damage the L322?
Towing within limits is fine, but it accelerates wear on the gearbox, transfer box, brakes and air suspension. An ex-tow car is not a problem if those systems have been maintained, but they deserve a careful check.
