Body & chassis

Last updated: 18 June 2012

The L322 was the first Range Rover with a monocoque (unibody) body, abandoning the separate ladder chassis of every previous Range Rover. Combined with all-round independent suspension, this gave a big jump in rigidity, refinement and on-road manners without losing off-road ability.

Key takeaway: The L322 was the first monocoque Range Rover with full independent air suspension, a huge leap in rigidity and refinement.

The monocoque body

A monocoque?Monocoque (unibody): the body shell itself is the load-bearing structure, instead of bolting a body onto a separate steel ladder frame. It's stiffer, quieter and usually lighter for a given strength. integrates the structure into the body shell rather than bolting a body onto a separate frame. Benefits for the L322:

  • Much greater torsional rigidity — better handling and refinement
  • Lower noise and vibration than a body-on-frame design
  • A modern platform able to carry air suspension and the 4WD hardware

At launch this made the Range Rover and the Ford Expedition the only two full-size SUVs with four-wheel independent suspension.

Suspension layout

  • Front: double-wishbone independent.
  • Rear: multi-link independent.
  • Springs: cross-linked electronic air at all four corners (see air suspension).

The independent setup, plus cross-linking, matched the articulation of the old live axles while hugely improving on-road behaviour.

Size & growth

DimensionFigure
Length~4,718-4,972 mm (by year/market)
Width~1,910 mm
Height~1,862-1,887 mm
Kerb weight~2.4-2.75 tonnes by engine
Towingup to 3,500 kg

Like every Range Rover generation, the L322 grew over its predecessor and adopted a more "butch", upright stance.

Ownership notes

TIP The monocoque means corrosion and structural condition matter more than on a separate-chassis car. On a 4.4 TDV8?TDV8. Land Rover's twin-turbo diesel V8 (3.6, later 4.4) — the 'AJD-V8' / 'Lion' engine, prized for huge torque., note the turbos are an "engine-out" job partly because of the packaging — some specialists remove the body to access them.

Watch suspension subframe mounts and bushes as the car ages: see common problems.
