Renzo Rivolta, the owner of the car company called Iso. Renzo started his business in making refrigerators then started producing small cars which eventually making cars that are simply magical even in today's time. A car that is so great is expected to be around for a long time in the car manufacturing business but why does it ceased production? But first lets start on how this unicorn landed on the roads.
Giotto Bizzarrini, the noted freelance Italian engineer who’d been on the staff at Maranello and was largely responsible for developing Ferrari’s celebrated 250 GTO, was hired to design a new chassis around Corvette running gear. Bertone was contracted for body styling and production; the youthful Giorgio Giugiaro penned the shape. Then started working on GT car for Iso. A year later, a result of all the hardwork a stunning Grifo A3L prototype coupe.
Grifo shared running gear and suspension with the Rivolta but was tuned for higher performance. The engine was Chevrolet’s 327-cubic-inch small-block V-8 as used in the contemporary Corvette, initially offered with a choice of 300 and 365 horsepower. With a top speed of at least 160 mph in 365-bhp form, the Grifo was as fast as any Italian supercar and as lovely to behold.
So how did this unicorn disappeared from the road? Simple, the problem was that the Iso marque had nowhere near the prestige and snob-appeal of Ferrari or Maserati, so it wasn’t easy to attract orders from the well-heeled types at whom the car was aimed. Then Iso switched it's Corvette engine to the Ford Cleveland Boss 351 4BBL engine, the car also known as the Grifo IR-8. Still utterly brilliant, sales began to dwindle due mainly to the oil crisis. Iso had never been a high volume seller, and it was probably inevitable that the company would eventually flew away from the road. Which is a such bummer.
