The 1965 Iso Rivolta IR 300: Why a Chevy V-8 in Italian Clothes Is Genius

Renzo Rivolta had a problem. The founder of Iso, a scooter manufacturer turned carmaker, was a multilingual engineer with a passion for racing speedboats and an uncompromising motto: “At the wheel of a car, I only enjoy myself above 120 mph.” That philosophy doesn’t mesh well with the Iso Isetta—the tiny microcar that made his company’s name. You can’t sustain 120 mph in a vehicle that weighs less than a grand piano without committing an aviation crime.

So Rivolta did what any visionary with a budget would do: he commissioned something properly quick. And instead of reinventing the wheel, he borrowed one from Detroit while grafting it onto Italian genius. The result? The 1965 Iso Rivolta IR 300—a grand tourer that’s now up for auction and represents one of the smartest automotive marriages ever consummated.

The Dream Team Behind the Machine

This wasn’t some half-baked exercise. Rivolta called on two of the most formidable talents in automotive history: engineer Giotto Bizzarrini and designer Giorgetto Giugiaro. Bizzarrini’s résumé includes work on the Ferrari 250 GTO and the engineering of the original Lamborghini V-12. Giugiaro’s design portfolio stretches across six decades and shaped some of the most iconic silhouettes ever stamped into sheet metal. These weren’t second-tier talents making a quick paycheck—they were titans.

What they created was elegance married to utility. The IR 300 designation refers to the horsepower delivered by a Chevrolet 327-cubic-inch V-8, routed through a four-speed manual transmission to the rear wheels. Think of it as a Corvette that attended finishing school in Milan, picked up impeccable manners, and learned how to dress.

The engineering was equally thoughtful: disc brakes at all four corners, fully independent suspension up front, and a De Dion rear axle out back. This wasn’t a gutless beauty—it was genuinely quick and properly suspended.

American Brawn in Italian Tailoring

By the 1960s, this formula had become something of a trend, and for good reason. The United States had perfected mass manufacturing and could produce dependable, potent engines. Italy had spent centuries learning how to make things beautiful. Combining them made absurd amounts of sense. You got reliability from Detroit and artistry from the Adriatic.

This particular example, finished in a striking turquoise over red leather, shows off the Rivolta’s proportions beautifully. It originally left the factory in red over black—a classic but arguably safer choice that might’ve made it look like yet another Ferrari knockoff. The turquoise is a statement. Topped with 15-inch Borrani wheels, it announces to anyone paying attention that something unexpected has just rolled into the room.

Pop the hood, and you’ve got 300 horsepower of Corvette mill ready to justify Rivolta’s philosophy about life above 120 mph. But here’s the real genius: if that engine needs a spark plug, a belt, or literally any common service item, you can walk into the parts counter at your local Chevy dealer and buy it off the shelf. It’s an Italian exotic that runs on the same supply chain as an Impala.

The Legacy of a Renaissance Man

Renzo Rivolta only lived until 1966—just one year after this car rolled off the assembly line. But in that brief window, he created a series of special cars that would outlive him by decades. The Rivolta IR 300 proved his point: that great engineering doesn’t require pretension, that solutions are sometimes better than purity, and that a good idea executed with the right people never goes out of style.

This particular example, which has been outfitted with an aftermarket air-conditioning system for summer cruising, represents exactly what Rivolta envisioned. Though honestly, with that V-8 soundtrack, you might just want to roll down the power windows and let the engine do the talking.

Why This Car Still Matters

In an era obsessed with heritage and authenticity, the Rivolta IR 300 sits at an interesting intersection. It’s not a pure Italian exotic—it’s a hybrid, a pragmatist’s choice, a car built by someone who valued speed and usability over ideology. That’s exactly why it’s brilliant. Collectors are increasingly wise to the fact that owning an exotic shouldn’t require a second mortgage and a direct line to a specialist mechanic three hours away.

The 1965 Iso Rivolta IR 300 offered then—and still offers now—the rarest of qualities: Italian soul with American common sense. Rivolta understood something that too many carmakers still haven’t figured out: that a car doesn’t have to be complicated to be special. It just has to be honest about what it is, and executed by people who actually give a damn.
