Maranello boss Amedeo Felisa dropped a huge hint that a hybrid concept would break cover before the end of the year.
"Not at Frankfurt, but shortly thereafter, probably at an American show," he told US magazine Car and Driver.
So it's likely that the first ever Ferrari hybrid concept model will make its public debut at the Los Angeles show in December.
The iconic Italian supercar firm has been under increasing pressure to examine ways to drastically slash its car's emissions.
Patent drawings detailing what was allegedly a Ferrari hybrid powertrain have already leaked onto the web.
Other less drastic options are expected to include downsizing engines and replacing them with high-revving turbo or supercharged units. Biofuels like E85 ethanol (actually a more potent fuel than petrol which lends itself to high performance) are also being considered.
"The ECU in the California can already adapt to E85, so the know-how is there," said Felisa.
