Prototype Ferrari LaFerrari Mule Heads to Auction at Monterey Car Week

Summary

• 2011 Ferrari LaFerrari Prototype M4 to be auctioned by RM Sotheby’s at Monterey Car Week, estimated to be worth USD 1.2m
• Early development mule for the LaFerrari, built on a modified 458 Italia chassis with a hybrid V-12 powertrain
• Not road-legal but a rare collector’s piece showcasing Ferrari’s hybrid hypercar evolution

RM Sotheby’s is offering a rare piece of Ferrari development history during Monterey Car Week: the 2011 Ferrari LaFerrari Prototype M4, expected to fetch between $900,000 and $1,200,000 USD. Internally referred to as “F150 Muletto M4,” this early test mule was part of the first phase of real-world development for the hybrid LaFerrari and features a hybrid V-12 powertrain mounted on a heavily modified 458 Italia chassis.

While the interior still resembles a 458, with black leather seats, tan carpets and a 9,000-rpm white tachometer, the car’s dashboard toggle switch and high-voltage warning label hint at its experimental purpose. On the outside, aggressive design cues like exposed rivets, large front air intakes, mismatched brakes, side-mounted powertrain access hatches and high-rise air intakes make it unmistakably a prototype. Though not homologated for road or track use, this development mule represents a critical step in Ferrari’s transition to hybrid hypercars and stands as a captivating collector’s item for Ferrari enthusiasts. Bidding is set to open on August 15 as part of RM Sotheby’s Monterey sale.
