Lancia Delta Integrale: The Ultimate Buying Guide

The Enduring Legend of the Lancia Delta Integrale

The Lancia Delta Integrale is not just a car; it's a motorsport icon, a rallying legend, and a highly sought-after collector's item. Revered globally by motoring enthusiasts, this Italian masterpiece dominated the World Rally Championship for years, etching its name into automotive history. Owning a Delta Integrale is a dream for many, but with their increasing value and complex heritage, purchasing one requires careful consideration. This guide aims to equip you with all the essential information needed to navigate the process of buying a Lancia Delta Integrale, from its storied past to the crucial checks you'll need to perform.

A Storied Past: From Group B Monster to Rally Champion

The journey of the Delta Integrale begins with its formidable predecessor, the Lancia Delta S4. Developed for the brutal Group B rallying era, the S4 was a technologically advanced, four-wheel-drive powerhouse. Lancia's need to compete with Audi's Quattro system led to the creation of the S4, a car that, despite its mid-engined layout and spaceframe construction, would share only its windscreen and grille with the standard Delta road car. The S4's engine, a marvel of engineering featuring twin-charging (both a supercharger and a turbocharger), was incredibly potent, producing immense power. While the S4 achieved notable rally successes, its reign was tragically cut short by the banning of Group B rallying following a fatal accident involving Henri Toivonen and Sergio Cresto.

With the demise of Group B, new regulations favoured production-based cars. Lancia, already having developed four-wheel-drive technology with the S4, adapted this to the Delta platform. The resulting Delta HF 4WD was an instant success, securing both manufacturers' and drivers' titles in its debut season. The evolution continued with the introduction of the Integrale in 1988, featuring a wider track and improved handling. This iteration, driven by Miki Biasion, clinched two drivers' titles. Further enhancements led to the 16-valve version in 1989, boasting increased power and refined dynamics, continuing Lancia's winning streak. The iconic "Deltona" variant arrived in 1991, coinciding with Lancia's withdrawal from rallying. However, the Delta's competitive spirit endured, with privateer teams continuing its legacy, ultimately securing a sixth World Rally Championship title, cementing the Delta's status as the most successful rally car in history.

The Road-Going Legends: Delta Integrale Variants

Lancia didn't just build rally cars; they produced incredible road-going versions that captured the spirit of their motorsport counterparts. These cars offered a taste of rally-bred performance for the discerning enthusiast:

Lancia Delta HF 4WD (1986-1987)

The genesis of the road-going Integrale, the HF 4WD, featured a 2.0-litre turbocharged 8-valve engine producing 165 horsepower. Its sophisticated four-wheel-drive system utilised an epicyclic centre differential and a viscous-coupling unit, sending power primarily to the front but with variable transfer to the rear. The front had an open differential, while the rear employed a Torsen unit. It was a significant step up from the standard Delta, offering impressive grip and performance.

Lancia Delta Integrale 8v (1987-1989)

Building on the HF 4WD, the 8v Integrale received wider wheel arches, larger tyres, and a more potent Garrett T3 turbocharger. Power increased to 185 horsepower, enabling a 0-100 km/h sprint in a brisk 6.6 seconds. Enhancements to the suspension and brakes further refined its handling, earning praise for its sharp steering and agility.

Lancia Delta Integrale 16v (1989-1991)

The 16v version, unveiled in 1989, was a direct beneficiary of Lancia's rally development. Visually, it was distinguished by a prominent power bulge on the bonnet, accommodating the new 16-valve engine. Power climbed to 200 horsepower, with a revised torque split favouring the rear for reduced understeer, a change influenced by rally drivers. Stiffer suspension, improved braking, and the introduction of ABS enhanced its performance credentials, though it offered a more demanding driving experience than the 8v.

Lancia Delta Integrale Evoluzione (Evo I) (1991-1992)

The Evoluzione, or Evo I, was a significant revision aimed at improving handling and competitiveness. It featured beefed-up suspension, wider tracks, and a reinforced steering system. The exterior received a more aggressive look with wider arches, new bumpers, side skirts, and a manually adjustable rear spoiler. Power from the 2.0-litre 16-valve turbo engine was boosted to 210 horsepower. Special editions like the Martini 5 and Martini 6 celebrated rally victories, featuring distinctive liveries and interior enhancements.

Lancia Delta Integrale Evoluzione II (Evo II) (1992-1994)

The final iteration of the Integrale, the Evo II, was developed purely for road use. It featured an updated engine control system and a slightly smaller turbocharger to reduce lag, resulting in 215 horsepower and 230 lb-ft of torque. Larger 16-inch alloy wheels, Recaro sport seats, and a MOMO steering wheel were standard. While Lancia's official rally involvement ceased, the Evo II continued to be a desirable performance car.

Limited Edition Variants

Beyond the standard models, Lancia produced several limited editions to commemorate rally successes and cater to specific markets. These include the Martini 5 and Martini 6 editions, celebrated for their iconic livery; the Verde York with its unique paint and trim; the Club Italia with its distinctive blue hue and performance upgrades; and various other special series like the Bianco Perlato, Blue Lagos, Gialla, Dealers Collection, and Edizione Finale, each offering unique styling and features.

Buying Your Delta Integrale: What to Look For

Owning a Delta Integrale is a rewarding experience, but these cars, especially those with a rally heritage, can be demanding to maintain. Many have been driven hard, and Lancia's reputation for reliability, while improving, still looms. However, a well-maintained Integrale can be surprisingly dependable.

Pre-Purchase Inspection is Crucial

Before parting with your hard-earned cash, a thorough inspection is paramount. Ideally, have the car inspected by a specialist familiar with Lancias. If that's not possible, be meticulous yourself. Remember, these are analogue machines with character, but they can also hide a multitude of sins.

Condition is King

Prioritise condition over mileage. While low mileage examples exist, they can be equally prone to issues if neglected. Look for a car that has been cared for, with a comprehensive service history. Inspect the car in daylight and, if possible, when the engine is cold to reveal any hidden problems.

Engine and Mechanicals

Engine Oil: Regular oil changes are critical. Check the oil condition – it should be clean, not black and sludgy. Any signs of metallic particles or a fuel/coolant smell indicate serious internal issues. Oil consumption is normal for these cars when driven hard, but excessive use or leaks are red flags. Listen for knocking or rumbling from the bottom end, which could signal bearing wear.

Cambelt: The cambelt and balance shaft belt are critical. They should be replaced at recommended intervals (typically every 40,000 km or 3 years). A snapped belt can cause catastrophic engine damage. Always verify the cambelt's replacement history through service records.

Turbocharger: Listen for any whistling or grinding noises from the turbo, especially under boost. Blue or grey smoke from the exhaust can indicate failing turbo seals or a cracked housing. Slow acceleration or delayed boost delivery are also warning signs.

Cooling System: Overheating is a major concern. Check for any signs of a blown head gasket: white smoke from the exhaust, oil in the coolant, or coolant in the oil. Ensure the coolant level is correct and that there are no leaks.

Transmission and Drivetrain: The gearbox should engage smoothly without grinding or whining. Check the clutch for slipping or a high engagement point. Inspect the differential oil for signs of neglect. The five-speed manual gearbox, while robust, is not invincible, so listen for any unusual noises during shifting.

Bodywork and Chassis

Rust: Rust is the Integrale's arch-nemesis. Common areas to inspect include the base of the windscreen pillars, around the windows, the rear tailgate lip, front door edges, wheel arches, and suspension turrets. Check the underside of the car thoroughly. Any signs of previous rust repair should be scrutinised for quality and the potential for recurrence.

Crash Damage: Look for misaligned panels, uneven panel gaps, doors that don't open or close properly, and inconsistencies in the paintwork. These can all indicate past accident damage. A car that has been repaired correctly is one thing, but poorly repaired damage can lead to significant problems.

Body Cracking: Due to the stresses of performance driving, some Delta Integrales can develop cracks in the bodywork, particularly around the windscreen corners and suspension mounting points. Chassis strengthening kits are available, but this is a significant repair.

Interior and Electrics

Inspect the interior for wear and tear, paying attention to the seats, dashboard, and trim. Check all electrical components, including lights, windows, and the heating/air conditioning system. Electrical gremlins can be a common issue, so ensure everything functions correctly.
