Ferrari F450 spy video – Click above to view the video after the jump

Catching a glimpse inside Ferrari's top-secret Fiorano test track in Maranello is a rare treat. Catching a developmental test mule for an upcoming supercar on video is another matter entirely. But as Ferrari prepares for the anticipated debut of the successor to its F430, the proverbial cat was bound to leap out of the bag.

You'll find the full video after the jump, where you'll be able to discern a few key differences between this and the F430 it replaces. We won't speculate on the cosmetics, as those will all have changed by the time the veil is lifted in Frankfurt, but there are a few mechanical giveaways worth noting. The big air intakes protruding from the rear end, along with the larger exhaust pipes, should help the enlarged, direct-injection V8 eclipse even the 430 Scuderia's 520-horsepower output. A redline approaching 10,000 rpm should also help the cause, which could be managed by the California's seven-speed dual-clutch gearbox to replace the F1-style robotized manual. Follow the jump to watch the footage for yourself.
