Those aesthetic changes include a new fascia that Lamborghini claims is more aerodynamic, while the vertical ducts on the outside of the lower intake optimize airflow around the front tires and those huge front wheels, while channeling more air toward the rear radiators. In back, there's a restyled diffuser, and a neat hexagonal exhaust outlet. Above that, there's a three-position active rear wing. All told, Lamborghini claims front downforce is up 130 percent while "overall efficiency" in high-downforce mode increases 50 percent and low-downforce mode improves 400 percent.
New for the Aventador is a trick four-wheel steering system, a first for a series production Lamborghini. The idea with the system is like other four-wheel-steering. At low speeds it turns the rear wheels in the opposite direction of the fronts, tightening the Lambo's giant turning radius. At high speeds, the system works in reverse by turning the rear wheels in the same direction as the fronts and providing improved stability.
But none of these style and tech changes are worth a damn without that big lump of fury in the Aventador S' middle. Like previous versions, there's a 6.5-liter V12, but its output is up to an SV-matching 740 ponies – torque is unchanged from the LP700-4 we tested in 2015, at 509 pound-feet. Max engine speed is up from 8,350 rpm to a wild 8,500 rpm. The result? Zero to 62 miles per hour in 2.9 seconds and a top speed of 217.
Prices for the 2017 Aventador S start at an eye-watering $421,350 and – we're guessing – can creep up near $500,000 with a few carefully selected carbon-fiber accents and Ad Personam options. Lamborghini is planning to start deliveries in spring 2017.
