The 458 Spider is powered by the midrear 570 hp 4499 cc GDI V8 that was named International Engine of the Year 2011. It delivers absolutely exceptional performance and is the state of the art in terms of engine technology. One of the main differences between this installation and that of the coupé version lies in the location of the engine air intakes. These are no longer on the B-pillars of the car, as was the case with the 458 Italia, but have been moved back to the rear spoiler where the gearbox and clutch radiators are all situated. The new air intake position also meant that the inlet tracts had to be redesigned to guarantee drivers of the 458 Spider the same driving pleasure delivered by the naturallyaspirated Ferrari V8 with the top down, and a specific mix of intake and exhaust sounds was honed to suit the car’s openair remit. Intake and exhaust inputs were equalised at between 3,000 and 5,000 rpm with calibrations of 3-5 dB, thanks to specifically developed silencers.The soundtrack that occupants hear in the cabin is particularly exhilarating with the top up too, thanks to work done on the harmonics. By partially lowering the wind stop in this configuration, drivers will find themselves even more enthralled by the sound.
For a car with these performance characteristics, the 458 Spider is particularly efficient in terms of its fuel consumption and emissions (275g CO2/km). This was achieved through a whole series of modifications, including the introduction of the HELE (High Emotion Low Emissions) System which incorporates key components such as: Stop&Start, which cuts fuel consumption by around 10 percent in urban cycles; a low-pressure fuel pump; Pulse Width Modulation-controlled brushless fans (the brushes are replaced by permanent magnets which completely eliminate friction), resulting in an overall reduction in consumption of around 6 percent; and an electronic variable displacement airconditioning compressor.
