Several photos of the upcoming replacement to the Murcielago, the Lamborghini Aventador, have surfaced online, but contrary to early reports they are not spy photos. Several sources have confirmed that the candid shots are actually from a drive event Lamborghini held and the photos were press photos provided by the manufacturer.

Giving probably out best look yet at what the upcoming supercar will look like, we already know a great deal about the vehicle. While the carbon chassis has yet to be officially confirmed, Lamborghini has announced that the car will use a 6.5-liter V12 engine making 700-hp at 8250 rpm, with 509 ft-lbs of torque available at 5500 rpm.

Possibly more impressive, Lamborghini has announced a new ISR (Independent Shifting Rods) 7-speed transmission. Rather than opt for the dual-clutch setup becoming popular among other automakers, the ISR is a single clutch unit and will deliver shift times up to half the speed of a dual-clutch setup. Lamborghini also claims that at 154 lbs., the transmission is far lighter than a dual-clutch version and is also more compact. The transmission is able to shift so quickly (40 percent quicker than the E-gear setup in the Gallardo) because rather than having several gears and one shift rod to engage them, there’s a shift rod for each gear, allowing one gear to be engaging as the other one is letting off. The transmission will come with three modes: Strada (automatic), Sport and Corsa.

Coupled with AWD and a new carbon fiber monocoque chassis that will shed as much as 500 lbs from the Murcielago, the new Italian supercar should hit 60 mph in as little as 2.9 seconds.

The official reveal for Lambo’s new supercar is set for the Geneva Auto Show this March.
