You are looking at one of the most powerful Ferrari 458 Spider units to roam the streets. It’s the work of Hennessey Performance which has modified the car’s 4.5-liter V8 engine to develop an impressive 738 HP (543 kW) at 8,400 rpm and a maximum torque of 720 Nm (532 lb-ft) achieved at 5,600 rpm. Thanks to this significant power hike, the car needs just 2.8 seconds from 0 to 62 mph (100 km/h) while the quarter mile is achieved in 10.5s at 137 mph (220 km/h). All these figures were possible by installing a stainless steel exhaust system, air-to-water intercooler and turbo downpipes.
Aside from the boost kit, Hennessey is also selling a KW adjustable suspension kit, carbon fiber exterior body kit, leather and carbon interior packages, as well as monoblock alloy wheels shod in Michelin Pilot Super Sport rubbers. If you want just the power boost, prepare to pay $59,995. This kit is offered by the American tuner with a 1-year / 12,000 miles limited warranty.
