A new leak suggests that Ferrari's upcoming 620 GT will get a 6.3-liter V12 making 740 horsepower.

Ferrari won't drop the sheet on its 599 GTB replacement, believed to be called the 620 GT, for a few more days. However, thanks to a number of leaks we now what this supercar might look like - and what could be under the hood.

While it was long known that the engine would be a potent twelve-cylinder unit, GTspirit claims to know the details: the motor will apparently be a 6.3-liter unit with 740 horsepower allied to a seven-speed dual-clutch gearbox. In comparison, the high-performance variant of the outgoing 599, the GTO, makes 670 horsepower. The 620 GT will reportedly accelerate from zero-to-60 mph in under three seconds and top out at around 200 mph.

Many rumors have claimed that the 620 GT will borrow styling elements from the 458 and the recently-launched FF, and the latest image, also posted on GTspirit, appears to confirm that speculation. The 620 GT also looks to have some design cues from the California convertible.

We'll know for sure if the image and powertrain details are accurate when the 620 GT makes its online debut on February 29th. After that, the latest Ferrari will greet the public for the first time at the Geneva Motor Show before hitting the market next summer.
