Wearing nothing except a thin camouflaging wrap--prototypes seen in previous spy shots always had fake body cladding attached--details of the new super can clearly be seen. The front shares an almost identical nose to the stunning Reventon, while the headlights appear similar to those on the equally stunning Sesto Elemento concept car from last year’s Paris Auto Show.
The rest of the car’s body features a much more fluidic design compared to the outgoing Murcielago, as well as side mirrors that are attached to the doors rather than at the corners of the windows.
The latest Lamborghini supercar is expected to carry the full title of Aventador LP700-4 and under its hood will be a brand new V-12 engine matched to a new automated manual transmission dubbed ISR. Still displacing 6.5-liters, the V-12 engine has been redesigned from scratch and is rated at 700 horsepower and 508 pound-feet of torque.
As for the new transmission, Lamborghini has revealed that the automated manual can match a dual clutch transmission for shift times thanks to Independent Shifting Rod technology--hence the name, ISR. Instead of taking place in series, as with a conventional gearbox, shifting can occur virtually in parallel. While one shifting rod is moving out of one gear, the second shifting rod can already engage the next.
Another relatively unique feature will be the car’s pushrod suspension design similar to that used in Formula 1 racing. The benefits of pushrod suspension are mostly those of packaging: without the need for tall suspension uprights, the car's profile, especially at the front, can be made much lower. Using rocker arms and pushrods to actuate the coilover spring/damper combo, a pushrod suspension also makes for less weight at the corners, as the damper system rides on the chassis rather than the wheel upright or control arms, further improving handling.
