Iso Grifo

A front-engined Italian GT built to beat Ferrari—with a Chevy V8 and no apologies.

The Iso Grifo is a 1965 Italian grand tourer styled by Giorgetto Giugiaro at Bertone and engineered by Giotto Bizzarrini. It uses American-sourced Chevrolet V8 engines and Borg-Warner transmissions. Production ran from 1965 to 1974, totalling 413 units. It was intended to compete with Ferrari and Maserati GTs.

Chapters & takeaways6
  1. 1:01
    The Brief

    Giugiaro designed the Grifo in 1963 as Iso Rivolta’s answer to Ferrari and Maserati.

  2. 2:15
    The Split

    Bertone handled styling; Bizzarrini handled mechanicals—two masters, one car.

  3. 3:55
    The Powertrain

    The first GL models used a 5.4-litre Chevrolet V8 and Borg-Warner 4-speed manual.

  4. 5:06
    The Line

    Its arched, curving shape defined Giugiaro’s early design language—and influenced the Mangusta and Ghibli.

  5. 6:21
    The Target

    It was built to compete directly with Ferrari and Maserati GTs—not as a boutique experiment, but as a commercial challenge.

  6. 7:27
    The Sequence

    It sits between the IR 300 (1961) and Fidia (1967) in Giugiaro’s sequence of Iso Rivolta commissions.

Worth your time?

Yes. Drive the whole thing.

What works
  • the balance of long-hood proportion and compact cabin that defines the front-engined GT silhouette

What does not
  • deliver consistent build quality across its 413 units

The written brief1 min read

What the car is and where it came from

The Iso Grifo is a limited-production Italian grand tourer made by Iso Autoveicoli S.p.A. between 1965 and 1974. Giorgetto Giugiaro designed it in 1963 at Bertone. Giotto Bizzarrini engineered the chassis and drivetrain. It was intended to compete with Grand Touring offerings from Ferrari and Maserati.

How it works, in terms someone would actually use

It places a Chevrolet 5.4-litre V8 behind the front axle, driving the rear wheels through a Borg-Warner 4-speed manual transmission. The driver shifts with a floor lever and feels engine torque directly through the wheel and seat.

What it gets right

It gets right the balance of long-hood proportion and compact cabin that defines the front-engined GT silhouette. Its arched, curving body language gives visual cohesion without relying on ornament. The cockpit positions the driver centrally relative to the wheel, pedals, and shifter.

What it does not

It does not deliver consistent build quality across its 413 units. It does not isolate the driver from engine noise or chassis vibration. It does not offer adjustable suspension, power steering, or any electronic driver aids.

What it changed

It proved that a non-prestige Italian manufacturer could commission a world-class designer and engineer to build a credible alternative to Ferrari and Maserati GTs—using off-the-shelf US powertrains as a strategic advantage.

Who it is for, and who it is not

It is for someone who values Giugiaro’s early arched and curving design language as a physical object—not as a collector’s trophy, but as evidence of a specific moment when Italian form met American engineering pragmatism. It is not for anyone who requires documentation, service support, or repeatable driving dynamics.

Is it worth your time

Yes—if you care about how Italian design reconciled American muscle with European grand touring intent in the mid-1960s. No—if you need verifiable performance data, production consistency, or modern usability.

Ford RS200Ghia · 1984The Ford RS200 is a purpose-built homologation special: mid-engined, all-wheel drive, plastic-fiberglass body by Ghia, built by Reliant in Shenstone to meet FIA Group B’s 200-unit rule. It exists only to enable a rally car—not as a design statement, luxury product, or road-going evolution.

Nissan 180SXNissan · 1989The Nissan 180SX is a Japanese-market fastback built from 1988 to 1998 on the S13 platform. It featured pop-up headlights and a liftgate. It launched in March 1989 and was sold exclusively through Nissan Prince Stores alongside the Skyline and Silvia. It used the CA18DET turbo engine initially, then upgraded to the SR20DET in 1991 and added the SR20DE in 1996.

Renault Clio V6 RSRenault Sport · 2001The Renault Clio V6 RS is a radical departure from the hot hatch formula: mid-engined, rear-wheel drive, hand-built, and deliberately impractical. It exists as a mechanical argument—against front-drive orthodoxy, against shared-platform economics, against the idea that a ‘hatch’ must behave like one. Its legacy is not volume or versatility, but velocity of idea.

Saleen S7Phil Frank · 2000The Saleen S7 is an American hand-built, high-performance sports car. It debuted on August 19, 2000, at the Monterey Historic Races. It was the first fully proprietary car produced by Saleen. Phil Frank contributed the body and interior CAD design and development. Its all-aluminium engine is a bored-and-stroked derivative of Ford's 351 Windsor small block with Cleveland-style canted valve heads. It is not based on the FE big-block. It produces 550 hp (410 kW) at 6,400 rpm.
