As far back as spring 2010, Fiat laid out several years worth of Ferrari road map.

So far it's been right on track, launching the FF and 458 Spider last year and the F12 Berlinetta this year.

It looks like things will run off schedule later this year... kind of.

Fiat had said that the much anticipated Enzo successor, known as the F70 internally, would make its debut this year, setting us up for a truly exciting year of Ferraris. According to Automotive News Europe (subscription required), Maranello still plans to introduce the F70 this year, only it will be a private introduction to VIP types only. A spokesman has revealed that the public debut is likely to be put off until next year's Detroit or Geneva show.

Ferrari Chairman Luca Cordero di Montezemolo confirmed what we basically already knew in stating that the car will be Ferrari's fastest, most powerful road car ever. That means the F12 will have a very short reign as Ferrari's speed and power leader.

The latest intel says that the F70 will be powered by an 800-horsepower 7.3-liter V-12--already enough to beat out the F12's 740-horsepower 6.3-liter V-12--that gets some assistance from a hybrid system capable of up to 120 horses.

Now, slide that powertrain into a 2,500-pound carbon fiber car packed with the latest tech, and you know that Montezemolo isn't exaggerating in calling it the fastest ever. We also don't doubt his words that Ferrari "want(s) to surprise people not just in terms of price but also with the car itself."

Only thing is, another year worth of rumors and leaks may just spoil that surprise.
