Two LaFerraris test at Fiorano Circuit

We don't need to say much about this video of two Ferrari LaFerraris testing at the Fiorano Circuit in Italy --caught by spy videographer extraordinaire Marchettino --except for “turn it up to 11.” In fact, we recommend you use a headphone-to-RCA converter and plug it in to the loudest stereo you have. That's the only way you can truly appreciate the Italian-opera wail coming from the 963 hp, 6.3-liter V12 as it boogies around the 1.8-mile, 12-turn test track. Marchettino said the camouflaged car must have a different exhaust because it sounded so much louder.

Mercedes SLS AMG Gullwing Electric – Official

Mercedes has confirmed they are planning an SLS AMG eDrive for 2015 As we suggested the other day, it looks like this will be known as the Mercedes SLS AMG eDrive. It will feature an in-board electric motor for each wheel, generating the equivalent of  526bhp, which should give the SLS eDrive similar performance to its conventionally driven sibling. By putting a motor at each corner, Mercedes are effectively endowing the SLS eDrive with an intelligent four wheel drive system.

In fact, there were more details on the handling pack for the 599 – the 599 HTGE Pack – than there were for the 599XX. But Ferrari has now remedied that, and supplied us with more information and some pictures.
