German tuner Mansory has created a one-off model for the billionaire art-collector James Stunt. The resulting Lamborghini Aventador 750-4 Superveloce J.S. 1 Edition features a carbon fiber shell that's fitted with a revised fascia and a front lip spoiler, as well as aerodynamic side skirts and a roof-mounted air intake. Under the hood, the 6.5-liter V12 engine has been equipped with an optimized ECU, a high-performance air filter and a new sports exhaust system, all of which enables the car to generate 818 horsepower and 553 pound-feet of torque (an increase of 78 hp and 46 lb-ft). The power boost allows the J.S. 1 Edition to achieve a 0-62 mph sprint time of just 2.7 seconds and a top speed of 220 mph.
