Let me preface these two clips with one simple thing: Do not expect to see much, or anything at all for this matter.
They're pretty poor videos.
However, what you do get to hear are what's being claimed by spies as the all-new Ferrari F70 V12 under wide-open throttle, and the Ferrari 458 Italia Monte Carlo.
The Monte Carlo will be to the 458 what the 348 Serie Speciale, 355 F1 Fiorano, 360 Challenge Stradale and 430 Scuderia were to the mid-engined, V8 class. With the 348 and 355 they were the particular model's swan song. For the 360 and 430, it became the vehicle's roadgoing, lightweight and hardcore wannabe racing version.
