Fiat is relaunching the iconic Alfa Romeo brand with the new mid-engined, rear-drive Alfa 4C compact sports car. The stunning new lightweight model, seen here officially for the first time at the Geneva motor show, will be the first of a range of new Alfas over the next few years, and will spearhead the Italian firm’s return to the US market.
The production two-seater 4C coupé, complete with its carbonfibre chassis, returns to the Geneva show two years after a concept of the same name was introduced.
Power for the new sub-1000kg model, which is tipped to cost less than £50,000 when it launches in the UK at the end of the year, comes from an all-aluminium turbocharged 1.7-litre engine. Alfa is keeping exact technical details of the 4C under wraps until Geneva on 5 March, only confirming figure being a power to weight ratio of less than 4kg for every 1bhp.
Information leaked by Alfa dealers in Switzerland suggests the 4C will be offered with 237bhp in its initial launch guise, which would mean the 4C would weigh 950kg, a figure that’s likely given the concept weighed 850kg and a production-spec interior is now fitted. A 0-62mph time of around 4.5sec has been mooted, with a top speed limited to 155mph.
The four-cylinder engine known as 1750 TBi is familiar from recent Alfas, including the Giulietta, but the block is now cast aluminium instead of iron, saving around 25kg. The engine gets direct-injection, MultiAir dual continuous variable valve timing and a new scavenging system that “gets rid” of any turbo lag. Bespoke intake and exhaust systems have also been developed for the 4C.
The result of these technologies is an engine with the potential performance of a 3.0-litre six-cylinder unit, but with the fuel economy and CO2 emissions of a smaller four-cylinder engine.
