Ferrari California has been on the market for some time now and the successor is expected to arrive in 2015.
Here we have the latest spy shots showing the chassis and engine testing mule testing in Southern Europe.
The test mule uses a modified body of the current California with some changes to the front lights and rear exhausts.
According to the photographer, this mule was much louder than a standard California which in current form packs 483bhp from a 4.3-litre V8, enabling it to hit 62mph in 3.8 seconds, while the top speed is 193mph.
The new model is expected to get a new name and the naturally aspirated V8 could be replaced with a turbocharged unit for improved performance, fuel economy and emissions.
The first mules were seen already in 2012 so we expect to see full body prototypes in the near future with a possible public debut in late 2014 or in early 2015.
