Previously the date for the replacement California had been the source of some debate, with Ferrari's mid-engined cars being on a five-year replacement cycle and its V12s on a seven-year cycle. Some had suggested a six-year cycle for the California convertible, however, pointing at a late 2014 reveal and early 2015 on-sale date.
A lightly disguised Ferrari California test mule was spotted earlier in the year, with obvious changes including a much higher bonnet line, a different front end and new lights. Sources suggested at the time that the car was testing a twin-turbocharged 3.8-litre V8, which has recently made its way in to the Maserati Quattroporte.
Currently the rear-drive California is powered by a naturally aspirated V8 that produces 483bhp and 375lb ft. It's capable of 0-62mph in under 4.0sec and has a top speed of 194mph. The new twin-turbo Ferrari-designed and built 3.8-litre V8 puts out 523bhp and 523lb ft.
The presence of notable bonnet louvres in the sketches of the new model potentially indicate that it too could receive a turbocharged powerplant; they would serve to reduce the high underbonnet temperatures that are typically associated with high-performance forced-induction engines.
Fitting a turbocharged engine would also help Ferrari meet increasingly demanding emissions and economy targets. An illustration of the chassis also suggests a flat undertray will be fitted, in order to reduce drag - which will again help improve performance and efficiency.
Recent patents for myriad hybrid technologies, including a rear-mounted hybrid system for a front-engined, rear-drive coupé, may indicate that the new California could also receive a hybrid powertrain. The California was notable for featuring many economy-related technologies when launched, and it was also the first production Ferrari with a stop/start system.
There has been some speculation that the images may be of a Ferrari FF coupé, or special one-off variant, but Ferrari already offer a high-performance front-engined coupé in the form of the Ferrari F12 Berlinetta. The new car also appears to feature the same central section as the California, but with a longer nose and different tail.
Ferrari declined to comment regarding the new design registrations.
