This Unusual Ferrari Prototype Might Be Valued Higher Than Your Home | Carscoops
In recent years, several prototypes of the extraordinary LaFerrari have been sold.
This particular prototype features a modified aluminum chassis designed to support the LaFerrari's 6.3-liter V12 engine.
Back in August 2022, this car was sold for $715,000 at an auction during Monterey Car Week.
The interior of this test mule is predominantly a standard 458 Italia, but it has an additional 12-volt battery included.
For many car enthusiasts, the LaFerrari represents the apex of the so-called Holy Trinity of hypercars. With some versions reaching prices exceeding $4 million, its esteemed status comes with a hefty price tag. However, what if you are fascinated by the LaFerrari’s history and engineering but don't want to own a complete version?
One compelling option could be one of the original prototypes used during the model's development; for instance, this early test mule known as the F150 Muletto M4.
Initially built as a Ferrari 458 Italia, this prototype has a significantly modified aluminum chassis tailored to accommodate the 6.3-liter V12 that ultimately powers the final production LaFerrari. The engine on its own generates 789 horsepower, a significant upgrade from the 458's 562-hp V8.
A Unique Exterior
As this vehicle served as a test mule, most of the original 458 body panels have been replaced with unconventional add-ons, including a redesigned front end and hood. The rear follows a similar pattern, with only the taillights and vents being sourced from the 458. While the exterior is quite unusual, the interior remains largely a standard 458 Italia, aside from the additional battery located in the passenger footwell.
RM Sotheby’s is overseeing the sale, with an estimated price range of $900,000 to $1.2 million. This isn't a trivial amount, especially for a car that cannot be registered for street use. Nonetheless, when compared to the price of a completed LaFerrari, it represents a unique chance to own a direct piece of the car’s developmental history.
Many LaFerrari prototypes have been sold over the years, including this particular car, which was auctioned by Mecum Auctions three years ago for $715,000. This price could be considered quite reasonable if it now sells for more than $1.2 million.
