“The Defender that shares nothing with the Defender: an aluminium monocoque on independent air springs that will out-climb its ancestor and then massage your back on the way home. Brilliant off-road, a little too clever for its own good in the workshop.”

PART 01

Overview

Where it came from, why it matters, and how it changed year to year.

The story

The L663 is the argument that ended an argument. For years, purists insisted a Defender needed a ladder frame and beam axles. Land Rover built one with neither, gave it permanent four-wheel drive, a two-speed transfer box, locking differentials and 900 mm of wading depth, and sold it in America again. It is quicker, safer, quieter and more capable than the truck it replaced. It is also a modern JLR, which means the things that go wrong are sensors, software and converters rather than swivel seals.

BREAKING THE LINEAGE

Land Rover showed its hand early with the DC100 concept at the 2011 Frankfurt Motor Show, a 100-inch-wheelbase sketch of a modern Defender. The production truck, styled under Gerry McGovern, was unveiled at Frankfurt on 10 September 2019. It was the first all-new Defender since 1983 and, by Land Rover's account, shares no components or technology with its predecessor: the body is an aluminium monocoque on JLR's D7x platform, and the live axles are gone in favour of all-round independent suspension.

Production moved too. The L663 is built at JLR's plant in Nitra, Slovakia, which opened on 25 October 2018. Deliveries of the five-door 110 began in early 2020, the three-door 90 followed late that year, and the 130 later kept the 110's wheelbase but added a longer rear overhang for eight seats. For the classic Defender faithful in the US, the more important news was simpler: after the NAS trucks left in 1997, Land Rover was selling a Defender here again.

WHAT IT CAN ACTUALLY DO

The hardware list reads like a checklist written by someone who'd been told it would be soft. Permanent four-wheel drive through a ZF eight-speed automatic and a two-speed transfer case, a bevel-gear centre differential splitting torque 50/50 that you can lock, and a locking rear differential. Every 110 rides on air suspension, which lifts it to 291 mm of ground clearance; the 90 can have coils (about 225 mm) or air. Land Rover quotes 900 mm (35.4 in) of wading depth on air (850 mm on a coil-sprung 90), and Wade Sensing uses the cameras to show you how deep you are.

It is a working truck in the numbers that matter to overlanders, too. Land Rover quotes up to 3,500 kg of towing in the UK and up to 8,200 lb in the US, a 300 kg (661 lb) static roof load for a rooftop tent, and up to 370 lb of dynamic roof load on the 110 and 130 with off-road tyres and the Expedition Roof Rack. Unusually for a unibody, a 4,536 kg load-rated front winch is officially supported. Off-road it simply walks up things the Series trucks would have had to winch.

ENGINES, V8S AND THE OCTA

Engines are JLR's Ingenium family: a 2.0 turbo petrol P300, a 3.0 mild-hybrid straight-six P400, a P400e plug-in hybrid for the 110, and in Europe and Australia a run of diesels, first 2.0 four-cylinders and then 3.0 mild-hybrid sixes badged D200, D250, D300 and later D350. From 2021 the supercharged 5.0 V8 P525 added 518 bhp, and 300 all-black V8 Bond Editions marked the truck's role in No Time to Die.

Then Land Rover went further. The OCTA, announced in July 2024, uses BMW's 4.4-litre twin-turbo mild-hybrid V8 with 635 PS (626 hp in US trim) and claims 0–60 mph in 3.8 seconds. It gets hydraulically interlinked 6D Dynamics suspension, sits wider and higher than a standard Defender, and fits 33-inch tyres from the factory. Land Rover has since taken an OCTA-based rally-raid Defender, the D7X-R, to the Dakar, where it won the Stock category on its 2026 debut. The G-Class now has a genuine rival on every surface.

LIVING WITH IT

The motoring press loved the new truck; owners have been more mixed. A TFL review collected reader accounts of faults within the first few hundred miles, and Defender2.net's L663 Faults & Fixes board is busy with DC-DC converter failures on mild hybrids, DPF and EGR sensor codes on the diesels, steering knocks and recall campaigns. None of it is the stuff you fix with a 13 mm spanner in a field, and an independent diagnostic tool has become as common an accessory as a roof rack.

The 26MY facelift, unveiled on 28 May 2025, brought flush lights and a 13.1-inch screen but left the structure alone. In September 2026 the Defender Wolf Series II, built on the same D7x platform, was launched to bid for the UK Ministry of Defence's Light Mobility Vehicle tender, putting the name back where the Series started. If you want the old recipe of separate chassis and beam axles, the Ineos Grenadier exists precisely because this truck abandoned it.

SIDEBAR · SPECIAL EDITIONS

Bond cars, Camel yellow and a Lego Defender

The Bond Edition (2021) was 300 V8 Defenders in all black with 22-inch black wheels, blue calipers and 'Defender 007' badging, priced from £105,000. The 75th Anniversary Edition was painted Grasmere Green as a nod to HUE 166, the first pre-production Land Rover. The Trophy Edition, in Deep Sandglow Yellow or Keswick Green, is a homage to the Camel Trophy that the classic 110 made famous.

For North America, the 2023 30th Anniversary Edition was a 500-unit run of Fuji White Defender 110 P300s on white steel wheels with the Expedition roof rack and side ladder, marking 30 years since the NAS 110. And if you can't afford any of them, Lego's 2,573-piece Defender set of October 2019 is one of the largest sets it has made.

Specs & capability

How it’s built, what it can do, and what fits under it.

How it’s built

The L663 throws out the ladder frame entirely. Its aluminium monocoque (JLR's D7x platform) carries independent suspension at all four corners, air-sprung on every 110 and optional on the 90, which gets coils as standard. Drive is permanent through a ZF eight-speed automatic and a two-speed transfer case with a lockable 50/50 centre differential and a locking rear differential. Off-road capability comes as much from software (Terrain Response 2, All-Terrain Progress Control, Wade Sensing) as from hardware, which is both why it is so good and why owners carry diagnostic tools.

BODYAluminium monocoque (D7x)No separate chassis; integrated body and frame.
SUSPENSIONIndependent, air or coilAir standard on the 110; the 90 offers coils or air.
4WDPermanent, lockable centre diffBevel-gear centre diff, 50/50 split.
TRANSFERTwo-speed (high/low)Behind a ZF eight-speed automatic.
REAR DIFFLocking / Electronic ActiveListed alongside torque vectoring by braking.
WADING900 mm (35.4 in)Air suspension; 850 mm on coil-sprung 90s. OCTA is quoted at one metre.

Buying one

What to pay, what to check, and how to tell a good one from a clone.

What they cost

Depreciation has made early trucks the bargains; low-mileage late 110s and special editions hold their money best.

2020–22 90 or 110, driver$27k–42k
2023 trucks, low-mile First Editions$45k–58k
Low-mile 2024–25 110, Carpathian and similar$68k–89k

Based on 15 Bring a Trailer sales in 2025–26 ($27,250–89,000, median $45,000); the two Carpathian Editions sold for $85,000 and $89,000. Prices move; checked October 2026. See live listings below.

What to check before you buy

  1. 01
    Recall and campaign statusHave a dealer or diagnostic tool confirm every open campaign is closed. Owners on Defender2.net report an airbag recall and the E005 campaign for 3.0 Ingenium diesels built between 1 March 2024 and 18 April 2026, where the auxiliary belt idler pulley can damage the oil pressure and temperature sensor, causing an oil leak and possible stalling.
  2. 02
    Oil-change historyThe headline service interval is long, and some trucks reach their first service on the original oil. Defender2.net members note the oil-change interval is driven by a separate condition-based counter and many owners change oil every 7,000–10,000 miles. A truck with only dealer visits at 21,000-mile intervals deserves a closer look.
  3. 03
    DC-DC converter (mild hybrids)MHEV trucks have suffered DC-DC converter failures, with owners reporting waits of two weeks to two months for parts. Ask whether it has been replaced and whether the relevant software updates are done.
  4. 04
    Diesel DPF and sensor codesFrequent regenerations (every 35–100 miles) and codes such as P24C6/P24C7 (PM sensor temperature) or P0401 (EGR flow) are documented on the diesels. Scan for stored codes and ask about regeneration frequency before buying a high-mileage D250/D300.
  5. 05
    Steering knock on rough roadsSeveral owners report knocking through the steering on corrugations, traced variously to the lower steering-column UJ, track rod ends, front lower control arms or a replacement steering rack under warranty. Wiggle the wheel at a standstill and listen.
  6. 06
    Coolant loss (P400)Petrol six-cylinder owners report coolant loss from turbo coolant line O-rings, leaky expansion tanks and stone-damaged auxiliary radiators behind the front intakes. Check the level cold and look for crusty residue.
  7. 07
    Coil or air, and which bodyLand Rover fits air to every 110; a 90 can be either. Coil 90s ride and tow fine but lose the air trucks' height adjustment, sit at about 225 mm instead of up to 291 mm, and are rated to wade 850 mm rather than 900 mm.

Spotting the real thing

The L663 has been sold in many engines, suspension setups and special editions, and the limited ones carry real premiums. Check what you're looking at.

  1. ID
    Coil or airLand Rover fits air to every 110 and 130. A 90 can be coil or air; coil 90s have about 225 mm clearance, wade 850 mm and have no height modes, while air trucks reach 291 mm at off-road height and wade 900 mm.
  2. ID
    EngineUS trucks: P300 2.0 four on earlier trucks, P400 3.0 mild-hybrid six, P525 5.0 supercharged V8 and the OCTA's 4.4 twin-turbo V8 (EPA's 2026 list also shows a 130 P300 as a 3.0 six). D-badged diesels and the P400e plug-in weren't sold in the US.

Owning one

Baseline service, the repairs you’ll actually do, and where the manuals live.

Post-purchase baseline

After you buy it

The L663 tells you when it wants a service, but its oil-life counter and the 21,000-mile/two-year headline interval are optimistic for how most owners use their trucks, and many used examples have only ever had dealer visits. Baseline the fluids, check every recall campaign is closed, and reset the service counters with a diagnostic tool afterwards.

Engine oil & filterDiesel: 0W-30 to JLR 03.5007 · ≈8.5–8.8 L (3.0 diesel, owner-measured). Petrol: 0W-20 (per Defender2.net members) [CONFIRM IN MANUAL]Then every 7,000–10,000 mi (owner practice); oil analysis on one D300 suggested 6,000

The oil-change interval runs on its own condition-based counter, separate from the 21,000-mile service counter. Draining via the sump plug means removing the undertrays; dipstick-tube extraction works if the probe reaches the bottom.

SYMPTOMSDue on the oil-life counter, or you want shorter intervals than the factory schedule.
THE FIXDrain through the sump plug: remove the two underbody shields (and any aftermarket front guard) to reach it. Defender2.net owners report refills of about 8.5–8.8 litres for the 3.0 diesel; one used 0W-30 to JLR spec 03-5007 with a new filter. Extraction through the dipstick tube works but the tube catches on ledges in the block, so mark the depth on your probe. Reset the oil service counter afterwards with a diagnostic tool, or the truck won't know it has fresh oil.

SYMPTOMSEngine light after cold starts, codes P24C6/P24C7 (particulate matter sensor temperature circuit), and regenerations every 100 miles or so.
THE FIXOne owner of a 2022 D250 replaced the PM temperature sensor, the last sensor in the exhaust after the DPF. After a week of cold starts and about 150 miles the light hadn't returned and short-trip regenerations stopped. Clear the codes afterwards.

SYMPTOMSJudder and hesitation at low-speed acceleration, especially on 1–2 and 2–3 shifts, then P0401 (EGR flow insufficient) and sometimes P006B.
THE FIXLog demanded versus actual EGR valve position with a diagnostic tool. In one documented 3.0 diesel case, the dealer replaced the inlet manifold pressure sensor but the fault returned. A member pointed to the exhaust pressure sensor in the 90-degree bend just after the turbo, whose narrow pipe can block with soot and confuse the EGR logic. If the valve itself is sticking, clean or replace it; short-trip use makes this worse.

275/60R20 (about 33 inches) is the popular step up from the factory 255/60R20. A Defender2.net owner fitted it to a coil-sprung truck on stock 8.5-inch 20s with no spacers and reports no rubbing, even off-road; others warn it can touch on some setups. 275/55R20 runs without rubbing on air suspension at full articulation, and Australian owners run 275/65R18 LT on 18s. The OCTA fits 33s from the factory because its axles move forward slightly.

How much can it tow?

Land Rover quotes up to 3,500 kg (UK) and up to 8,200 lb (US). Owners describe the air-sprung 110 as a very stable tow vehicle because it self-levels.

How deep can it wade?

900 mm (35.4 in) on air suspension, with Wade Sensing using the cameras to show water depth. Land Rover's 21MY Defender 90 data sheet rates coil-sprung 90s at 850 mm, and the OCTA is quoted at one metre.

Can I put a rooftop tent on it?

Yes. Land Rover quotes a static roof load of up to 661 lb (300 kg) and a dynamic load of up to 370 lb on the 110 and 130 (260 lb on the 90) with off-road tyres and the Expedition Roof Rack. V8 models have no dynamic roof rating, and the OCTA's is zero in OCTA mode.

Coil or air suspension?

Land Rover fits air to every 110. The 90 can have coils or air. Coil 90s give about 225 mm of ground clearance against up to 291 mm at off-road height on air, wade 850 mm instead of 900 mm, and lose the height-adjustable modes.

Does it have locking diffs?

It has a lockable centre differential and a locking rear differential (Land Rover's Electronic Active Differential), plus brake-based torque vectoring and a two-speed transfer case.

Can it take a winch?

Yes. A front-mounted 4,536 kg (10,000 lb) load-rated winch is officially supported, which is unusual for a unibody.

How often should I change the oil?

The headline service interval is up to 21,000 miles or two years, but Defender2.net members point out that oil changes are flagged by a separate condition-based counter, often around 15,000 miles for diesels in mixed use. Many enthusiasts change oil every 7,000–10,000 miles regardless.

SOURCE · DEFENDER2.NET
Which engine should I buy?

US trucks launched with 2.0 four-cylinder and 3.0 six-cylinder engines, and Land Rover USA's current 110 spec page lists only the 3.0 six, with the OCTA sold as its own model (EPA still lists 2026 2.0 and 5.0 V8 trucks). In Europe and Australia the D250/D300 diesels are the long-distance favourites, though the mild hybrids have had DC-DC converter failures and the diesels have DPF and EGR sensor faults.

Is it reliable?

It's better than its reputation off-road and worse than a Toyota in the workshop. A TFL review collected early-ownership faults, and common owner reports include DC-DC converters on MHEVs, PM/EGR sensor codes on diesels, steering knocks and several recall campaigns. Keep it on warranty or budget for a diagnostic tool and a good specialist.

SOURCE · WIKIPEDIA / DEFENDER2.NET
What fuel economy should I expect?

EPA rates the 2026 3.0 mild-hybrid six at 18 mpg city and 22–23 mpg highway, the 5.0 V8 at 14–15 city and 18–19 highway, and the OCTA at 15/19. Land Rover's 21MY Defender 90 data sheet quotes 7.6 L/100 km (NEDC equivalent) for the diesel. One D300 owner reported 40 mpg (imperial) cruising at 110 km/h across France.

Who makes the good stuff, where owners gather, and who to watch.

Common modifications & who does them

ROCK SLIDERS, LADDERS & PROTECTIONSills and rear corners are the first things a 110 hits; Terrafirma's sliders with tree bars and rear ladder are popular L663 fits.
ACCESSORIES & SPARE-WHEEL KITSpare-wheel mounting kits, security and trim parts aimed squarely at the L663.
BULL BARS & RADIATOR PROTECTIONThe auxiliary radiators behind the front intakes are vulnerable to stones; an Australian owner points to Offroad Animal's Toro bar as one that protects them.
ALL-TERRAIN TYRESBFGoodrich KO2 and General Grabber AT3 are owner favourites; the Grabber AT3 is listed in Land Rover's own iGuide and is 3PMSF-rated.
US PARTS & BUILDSNorth America's big Land Rover parts house runs L663 builds, including an OCTA on 35-inch tyres with a winch bumper.
