The 458 Spider is powered by 4,499 cc (4.499 L; 274.5 cu in) V8 engine derived from a shared Ferrari/Maserati design, producing 570 PS (420 kW; 560 hp) at 9,000 rpm (redline) and 540 N·m (400 lb·ft) at 6,000 rpm with 80% torque available at 3,250 rpm.
The engine features direct fuel injection, a first for Ferrari mid-rear engine setups in its road cars.
The convertible variant of the 458 Italia features an aluminium retractable hardtop which, according to Ferrari, weighs 25 kilograms (55 lb) less than a soft roof such as the one found on the Ferrari F430 Spider, and can be retracted in 14 seconds.
The standard transmission is a Getrag dual-clutch 7-speed transmission, similar to the Ferrari California. There is no traditional manual option, making this the second road-car after the Enzo to not be offered with Ferrari’s classic gated manual.
The car’s suspension will feature double wishbones at the front and a multi-link set-up at the rear, coupled with E-Diff and F1-Trac traction control systems, designed to improve the car’s cornering and longitudinal acceleration by 32% compared to its predecessors.
The brakes include a prefill function whereby the pistons in the calipers move the pads into contact with the discs on lift off to minimise delay in the brakes being applied. This combined with the ABS has reduced 100–0 km/h (62-0 mph) braking distance to 32.5 metres (107 ft).
Ferrari’s official 0-100 km/h (62 mph) acceleration is less than 3.4 seconds, while top speed is over 319 km/h (198 mph), with a fuel consumption in combined cycle (ECE+EUDC) 13.7 L/100 km (20.6 mpg-imp; 17.2 mpg-US) while producing 320g/km of CO2.
