This Ferrari LaFerrari seems to defy the laws of mechanics and time! Produced in just 499 examples, born in 2013 with its mythical 6.3-liter naturally-aspirated V12 backed by an electric motor inspired directly by F1, it represents the culmination of Maranello's technological know-how. However, even a hybrid hypercar of this level can eventually run into trouble, especially when its owner doesn't hesitate to drive... a lot. This is precisely the case with this LaFerrari, which has clocked up 155,000 km - a totally unreal figure for a model of this type - and has just suffered its first serious electrical breakdown.
The story begins when the car's electric motor, a PMSM from the Hy-KERS system, starts to malfunction. Diagnosis revealed an internal sensor fault, a component integrated directly into the stator, making it impossible to replace via a commercially available part or via Ferrari. In a workshop other than the one chosen by the owner, the proposal would have been simple: change the complete motor, at a cost of around €31,000. A staggering sum, but almost logical when you're talking about such a sophisticated component of a hybrid hypercar.
That's where EV Clinic comes in, a Croatian workshop that's becoming increasingly well-known for its top-level work on hybrid technologies. Ferrariespecially since their incredible repairing a LaFerrari battery which had saved another owner a €180,000 bill. Once again, the technicians tackled the problem like surgical engineers. By manually measuring the still-functioning redundant sensor, they were able to reconstitute the original characteristics of the faulty sensor and create a replacement. The component is no longer available from Magneti Marelli or Ferrari, yet they managed to bring the engine back to life. In the process, they discovered that someone had opened the unit before and disconnected a wire from the connector without ever reconnecting it. The error was corrected, the part reassembled, the system tested, and the Hy-KERS motor declared operational.

This case is all the more fascinating in that it doesn't concern just any electric motor. According to EVclinic, the unit in question is a prototype, a one-off developed before the LaFerrari went into production. A rare element whose repair would simply have been impossible without highly specialized know-how. Thanks to this meticulous approach, the owner avoided the €31,000 bill corresponding to the complete replacement of the engine at the OEM rate. A considerable saving, and a demonstration of what repairs can achieve when carried out by the right people.
