The S1 is powered by a turbocharged 2.5-litre four-cylinder engine producing a substantial 450bhp – given the size of the engine – and 350lb ft of torque.
The production-ready supercar will be finished in 2019. At that stage grant assistance will stop but work will continue.
Alfa Romeo is said to be prioritizing the vehicle's development in order to increase the brand's global appeal and to possibly increase profit margins.
