Pininfarina is the design house that has been responsible for pretty much every great Ferrari production car ever built. Ferrari says that the LaFerrari hypercar was designed without input or help from Pininfarina. It's more like Pininfarina gave Ferrari all the ingredients, and they baked them into a beautiful, delicious pie.
Luca di Montezemolo has been quoted as saying that "there is nothing from Pininfarina in this car."
Strictly speaking, that is true. Pininfarina proposed a design for the LaFerrari but Ferrari said they designed the car in house. Pininfarina's name doesn't appear on the car anywhere and they did not consult or provide input into the design of the LaFerrari.
But there are a number of elements on the LaFerrari that are definitely Pininfarina influenced. Headlights like those from the 458 Italia, F12, and FF make an appearance, all three of which are Pininfarina-designed cars. However, there are elements from the front quarter back that are even more distinctly Pininfarina-esque.
Look at the greenhouse and rear-end. If it wasn't influenced by Pininfarina's design for Jim Glickenhaus' Ferrari P4/5, then I don't know what was.
Ferrari is totally right to say that the LaFerrari wasn't designed by Pininfarina and they weren't involved. I also understand the school that hates hearing people say "this car looks like another car therefore it's awful." I do too.
But not to give a nod to the inspiration that led to one of the very, very few cars that were designed in-house by Ferrari? There had to be some sort of inspiration, right? All car designers tend to use elements of past designs in the latest one. It gives it a link to its history, and the P4/5 is definitely part of that history.
Why not say it and give some credit to Pininfarina, the company that helped make Ferrari the massive success that it has always been? Curious decision.
