The engine – Alfa’s familiar turbocharged, direct-injection 1742cc four-cylinder petrol motor – is some 22kg lighter than that found in the Giulietta, thanks to a new cast aluminium block in place of the regular cast iron item. Tuned to deliver a peak of 237bhp at 6000rpm and a fat 258lb ft of torque between 2200 and 4250rpm, it trades top-end effervescence for low- and mid-range accessibility.
For the Spider there’s now a choice of three exhaust systems – standard (loud), racing (very loud) and, at extra cost, Akrapovic, which has a switchable valve giving a choice between the two volume settings. With the Race Pack’s exhaust fitted, the 4C is very noisy, emitting a hollow, resonant fwaarp that’s two parts Fiat 500 Abarth Esseesse and one part Ferrari 458 Italia at less than stratospheric revs. It’s mated to Alfa’s six-speed TCT dual-clutch paddleshift transmission.
