Alfa claims that the layout, materials and features are all "designed and built for maximum driving satisfaction".
The 4C features a carbon monocoque chassis, which is left on display at various points in the cabin to "enhance the sense of light weight, technology and uniqueness".
Both the dashboard and door panels have an asphalt-look finish. The seats, constructed from composite materials to save weight, are claimed to offer a good driving position without compromising comfort.
Alfa states that the dashboard is simple and clear, with digital instruments and wheel-mounted gearshift paddles. The pedals and footrests are fabricated from aluminium.
The new sub-1000kg model, which is powered by a turbocharged 1.7-litre engine, is expected to cost less than £50,000 when it launches in the UK at the end of the year.
