Gianpiero Moretti gave Formula 1 a new look in 1964, albeit from the driver’s perspective. After struggling with the oversized steering wheel in his own race car, he devised a solution: a hand-made, alloy-spoked, small-diameter steering wheel. With a thick, leather-covered rim, the grippy wheel made it easier to drive the car. By 1966, nearly all F1 drivers were using one of Moretti’s wheels.
His success in Formula 1 gave birth to Momo—a company name made from the first two letters of Moretti and Monza. With the creation of the Prototipo, around 1966, sports car owners were finally able to enjoy the benefits of his original concept.
The earliest design had the name “prototipo” engraved in lower-case, sans-serif letters on the center spoke. Later on, the name would be painted. The spokes were anodized in silver or black and drilled with two or three holes each, holes that gradually increased in size as they moved toward the steering column.
Four diameters were available at the introduction of the Prototipo: 320, 350, 370, and 380 millimeters as measured from outer edge to outer edge—though custom sizes were specially produced for some race cars.
Gianpiero Moretti sold Momo in 1996. The company’s current owners still produce the Prototipo, and it remains true to the early design—though there are differences. The current version is only offered in one size—350 mm—and the painted Prototipo name on the front of the center spoke now has a rounded rectangle around it.
The Momo Prototipo, with its thicker grip and leather spoke pads, is arguably the most popular steering wheel for early 911, 912, and 914 hot rods. The Prototipo is seen so often in older Porsche street cars that it’s hard to believe it wasn’t offered as an option. Is it so popular because it hasn’t changed much in 51 years? Maybe. Or maybe it’s just hard to improve on a design born of the golden era of F1. 🏁
