Lamborghini's 2018 Aventador is the Bolognese-based carmaker's latest scissor-door, mid-engine supercar. The sleek, sharp-edged machine cuts a sinister profile that says much about its capabilities on the road. The stiff monocoque chassis is made entirely of carbon fiber--a Lamborghini first--and the body is a mix of carbon fiber and aluminum, with a 3-position rear wing that deploys at different speeds. The heart of the Aventador--as is the case with every Lamborghini--is its engine. The car is powered by a mid-mounted 6.5L V12. The engine features variable valve timing and a dry sump lubrication system, which allows it to sit lower in the car for an improved center of gravity. The big V12 produces 740 hp and 507 ft-lb of torque in the Aventador S and 770 hp & 531 ft-lb of torque in the SVJ model. All that power is put to the road through a smart all-wheel-drive system and a 7-speed sequential manual transmission capable of near-instantaneous shifts. The Aventador rides on alloy wheels (19-inches front, 20-inches rear) and Pirelli PZero tires, with large carbon ceramic disc brakes providing stopping power. Suspension is an advanced system fitted inboard via pushrod monotube dampers, much like the setup found on open-wheel race cars. The cockpit is an exercise in race-car-for-the-street ergonomics. All instrumentation is displayed on an LCD screen, with a separate LCD for the navigation and stereo system. Interior surfaces are leather and available in nearly any color combination, thanks to Lamborghini's "Ad Personam" customer individualization program. Driver-controlled electronic stability control and anti-lock brakes are standard, as is cabin full of intelligent airbags. The hyper performance-oriented Aventador Superveloce takes the ridiculous speed of the Aventador to another level. Magnetic adaptive suspension makes the LP750-4 handle even flatter and more responsively. Weight savings have been taken everywhere; Lamborghini removed sound deadening, floor carpeting and the entertainment system. The interior is much more like a race car-- spare and bare-bones. The Superveloce gets an even more powerful version of the V12, this one's good for 750 horsepower. The result is a hard-core speed monster designed for the most well-heeled car buyers out there.
