ISO Rivolta classic car purchase

History of the ISO Rivolta

Launched in 1962 at the Turin Motor Show, the ISO Rivolta marked a new chapter for the Milan-based manufacturer that began life building refrigerators and motorcycles. Renzo Rivolta steered ISO Automoveicoli S.p.A. towards building refined cars, assembling a dream team that included ex-Ferrari engineer Giotto Bizzarrini and design prodigy Giorgetto Giugiaro under Bertone. The result was a technically advanced, elegant 2+2 coupé on a sturdy steel box chassis. Rare on the road, with just under 800 units built between 1962 and 1970, the Rivolta changed perceptions of how a high-speed grand tourer could reliably combine Italian flair with American power.

Model history

The Rivolta IR 300 GT debuted with a 5.4-litre Chevrolet Corvette V8 and a fully synchronised Borg-Warner four-speed gearbox, sometimes offered with automatic transmission. The chassis, drafted by Bizzarrini and Raggi, incorporated advanced suspension: double wishbones and coil springs up front, a De Dion rear axle, and four-wheel disc brakes. Further evolutions included the IR 340 and IR 350, pushing output and top speed even higher. Production ended in 1970, leaving a legacy of less than 800 examples—today, about 300 are thought to survive globally.

Highlights and unique features of the ISO Rivolta

Few grand tourers of the 1960s marry Italian coachwork with American V8 power so effectively. The ISO Rivolta set itself apart via Bertone's understated-yet-luxurious design, substantial chrome grille, and panoramic glass. Inside, Veglia dials, real wood, and rich leathers (optional over the standard synthetic cover) define its opulent yet purposeful cockpit. Comfort and performance were both central to the concept: true seating for four, a boot suited to grand touring, and features like Campagnolo alloy wheels, electric windows, and (occasionally) air conditioning. The De Dion rear axle offered remarkable stability for the period, while central knock-off wheels by Borrani added a motorsport touch.

Technical data

Special editions and limited models

Alongside the original IR 300, ISO introduced the more potent IR 340 and IR 350 models, identifiable by their higher-output Corvette V8s (as high as 340 PS and a theoretical 228 km/h). Ultra-rare variants with factory air conditioning, special paintwork, or specific export features are sporadically found, sometimes destined for the French market or delivered in bespoke trim. Campagnolo alloy wheels and luxury options such as electric window lifts further elevated specific vehicles above the standard specification.

Known issues and weak spots

While the underlying Chevrolet V8 and Borg-Warner transmission are robust and straightforward to maintain, buyers should pay careful attention to chassis corrosion, especially around the steel box frame. The premium finishes, especially original leather and wood interior components, require expert restoration and proper care to preserve their value and appearance. Genuine Bertone body panels and unique ISO-specific trim parts can also be challenging and expensive to source. As with most grand tourers of the period, diligent records and thorough rustproofing contribute significantly to longevity. There are otherwise few model-specific mechanical flaws due to the use of proven American running gear.

Engine and performance, transmission and handling

Lively acceleration comes courtesy of the US-sourced Chevrolet V8, delivering abundant torque and effortless cruising power. Factory output started at 300 PS in the IR 300 with later IR 340 and IR 350 models offering even more. The rear-wheel-drive layout, combined with Bertone’s rigid body and advanced De Dion rear axle, allows for confident, composed handling at motorway speeds. The four-wheel disc brakes and excellent weight distribution stand out when compared with many Italian rivals of the era. The Borg-Warner gearbox is direct and reliable, while some cars offer the greater ease of a factory automatic.

Popular variations include:

1. IR 300 GT (1962–1967): 300 PS, 4-speed manual, 218 km/h top speed
2. IR 340: 340 PS, 228 km/h top speed

Each iteration refines the grand touring formula, favouring everyday use and relaxed, high-speed confidence over outright race track orientation. - IR 300 GT: Strongest market presence, all-around performance

• IR 340/350: Enhanced power/rarity, more collectable features

Interior, comfort, exterior and design

The ISO Rivolta’s exterior language reflects Giorgetto Giugiaro’s pursuit of balance and restraint, with a long bonnet, assertive grille, and classic 2+2 coupé profile. Chrome brightwork highlights Bertone’s lines, and expansive windows ensure a naturally lit interior. Inside, serious attention to driver ergonomics—steering wheel, shifter, and pedals—translates into comfort for long journeys. Leather upholstery (often optional but highly prized), wood dashboards, and Veglia gauges elevate the ambience. Campagnolo wheels, central lock nuts (Borrani), and high-grade finishes underline its sporting intent, while rare touches like electric windows and air conditioning speak to its luxury aspirations. Accessories and customisation were possible from the factory or specialist fitters, making each example potentially unique.

Other relevant features

The combination of American large-series technology with elegant Italian craftsmanship made the Rivolta both reliable and characterful, setting it apart in its price class against Ferrari, Maserati, and Aston Martin. Export models, including those delivered new to France, sometimes feature unique market-specific details, underscoring the Rivolta’s international appeal. Market history shows consistent interest among enthusiasts and collectors.

Summary

The ISO Rivolta stands out for its sophisticated mix of Italian design and dependable American V8 power. Produced from 1962 to 1970 in extremely limited numbers by Bertone under the direction of ISO, it offered high-speed comfort, precise handling, and luxury finishes. Today, it’s a sought-after classic for grand touring fans who appreciate rare engineering collaborations and the drama of 1960s European design.
