Peugeot 806 as a used car

The Peugeot 806 was one of the pioneers of the large MPV segment when it launched in 1994. Shared with Fiat Ulysse, Lancia Zeta and Citroën Evasion, it offered seven-seat versatility, sliding side doors and engines ranging from economical diesels to punchy petrol units. Production ran until 2002, after which it was succeeded by the 807. Today, a well-maintained 806 can deliver cavernous space and family-friendly practicality at bargain prices. This deep dive uncovers its technical parameters, ownership quirks and buying tips for anyone eyeing a used example.

Heritage and Evolution

Joint-Venture Origins

Peugeot partnered with Fiat Auto in the early 1990s to develop a purpose-built large MPV platform. Sharing design, engineering and assembly resources kept development costs down while allowing each brand to tailor styling and trim. The 806 arrived alongside its siblings with unique front and rear clip styling and Peugeot’s six-digit badging.

Facelift Changes

In 1998, the 806 received a mid-cycle refresh. Externally it gained a reshaped grille, smoother bumpers and new wheel covers. Interior tweaks included improved seat fabrics, a redesigned dash center stack and optional air conditioning. Mechanically the facelift introduced a modern 2.0 HDi diesel, replacing the older turbodiesel and boosting efficiency.

Design and Dimensions

Exterior Packaging

With a length of 4,592 mm, width of 1,840 mm (excluding mirrors) and height of 1,650 mm, the 806 strikes a commanding road presence. Sliding rear doors on both flanks permit easy access in tight parking bays. Ground clearance of around 160 mm suits urban driving while keeping the ride composed.

Interior Space and Flexibility

The standard configuration seats seven across three rows. Second-row individual seats slide on rails up to 200 mm fore and aft and fold flat. The third row folds into the floor to create a flat load bay. Boot volume varies from about 350 L with all seats upright to over 2,500 L with all rear seats stowed.

Engine Lineup and Performance

Petrol Engines

1.8 16v four-cylinder

• Power: 90 hp at 5,500 rpm
• Torque: 145 Nm at 4,000 rpm
• Transmission: 5-speed manual
• Fuel consumption: ~8.5 L/100 km

2.0 8v four-cylinder

Real-World Driving Character

The 2.1 XUD turbodiesel is celebrated for its torque-rich pull, making steep country roads or fully laden trips effortless. Petrol variants feel under-powered in hilly terrain but reward relaxed urban cruising. The HDi diesel remains the most efficient and refined choice, with quieter operation and lower emissions.

Transmission and Drivetrain

All 806 models are front-wheel drive. Manual gearboxes prevail, with smooth-gating five-speed units on most engines. The 2.0 8v and 2.1 XUD offered a four-speed automatic—useful in stop-start traffic but less economical at high speeds. Clutch life on manuals can exceed 200,000 km if driven gently; automatics require periodic fluid and filter changes to avoid shift flare.

Technical Specifications

Common Issues and Reliability

Engine and Drivetrain

• Timing-belt interval is 100,000 km or five years; failure risks major damage.
• Early 1.9 TD heads can develop hairline cracks if overheated.
• HDi high-pressure fuel pumps occasionally leak; watch for hard starting or rough idle.

Suspension and Body

• Rear trailing-arm bushes wear around 120,000 km, causing wheel shimmy at low speeds.
• Door-rail rollers on sliding doors can seize if not cleaned and greased.
• Rust often appears on lower door edges, sill ends and rear tailgate bottom.

Electrical and Comfort Features

• Central-locking actuators may fail, leaving doors unlocked or jammed.
• Electric window motors on early cars suffer gear-strip if operated under heavy load.
• Climate-control flap actuators can stick, leading to poor temperature regulation.

Buying Guide for a Used 806

Pre-Purchase Checklist

1. Review service book for timing-belt, clutch and gearbox-service records.
2. Test sliding doors, tailgate and seat-rail adjustments for smooth operation.
3. Scan for engine, ABS and airbag fault codes.
4. Drive on varied roads to assess steering play, suspension noise and transmission shifts.
5. Inspect underside for corrosion around subframes, brake lines and sill joints.

Price Ranges and Depreciation

Expect to pay between €1,200 and €3,000 for well-preserved 806s. Early-run high-mileage diesels cluster at the lower end, while low-mile HDi automatics and 16v petrols command closer to €3,000. Depreciation has plateaued, making value predictable.

Ownership and Running Costs

Fuel and Maintenance

• Annual fuel spend for 20,000 km: ~€1,400 on diesel, ~€1,900 on petrol (EU prices).
• DIY oil and filter kit costs ~€60; dealer service runs €200–€300.
• Timing-belt with water pump and tensioner replacement averages €350–€450.

Insurance and Taxation

Insurance falls into mid-tier MPV categories; premiums vary by driver profile. Road tax in many countries ties to engine displacement—expect higher rates on 2.0 and 2.1-litre models.

Pros and Cons

Pros

• Genuine seven-seat flexibility with simple modular seating
• Economical HDi diesel delivers low running costs and strong torque
• Sliding doors and high-roof ease passenger access
• Low purchase prices with slow depreciation

Cons

• Dated design and safety tech compared to modern MPVs
• Rust-prone areas demand diligent inspection and DIY prevention
• Underpowered petrol engines struggle when fully loaded
• Spare-part availability for L-series engines and body panels may be limited

Conclusion and Alternatives

The Peugeot 806 survives today as a pragmatic seven-seat solution for large families, club transport or leisure pursuits. Its spacious cabin, economical HDi engine and sliding-door convenience remain hard to beat at its price point. If you crave more modern styling, safety gear or infotainment, consider successors like the Citroën C8, Fiat Ulysse II or later Peugeot 807. Properly inspected and maintained, a used 806 can deliver years of no-frills, no-stress motoring for minimal outlay.
