Performance and 0-60mph time
Considering just the numbers, the Alfa 4C is impressive. It has a power-to-weight ratio of 269bhp/ton. That’s partly thanks to its 1750cc (actually 1742cc, if we’re being precise) engine producing 237bhp. But it is its low weight, thanks to it’s carbon fibre chassis that helps boost its performance.
The 4C Coupe and Spider share the same drivetrain, and because of that carbon fibre chassis remains reasonably stiff even with out a roof, the Spider is only 45kg heavier. The extra weight makes such little difference that Alfa claim the same performance figures for them both; they reach 0-62mph in 4.5sec and have a top speed of 160mph.

The featherweight Alfa certainly feels quick. In the higher reaches of its engine, the 4C flies down a road. The 4C will certainly test your commitment way before it reaches its own limits.
