The new Alfa Romeo 4C – A Lightweight Mid-engined Sports CarSeptember 17, 2013
The new Alfa Romeo 4C is a lightweight mid-engined sports car that promises performance and efficiency, combining a 0 to 62mph time of just 4.5 seconds with 41.5mpg and 157g/km CO2 emissions.
Designed and engineered by Alfa Romeo and built at the Maserati plant in Modena, the Alfa Romeo 4C employs the latest technologies of Alfa Romeo’s newest models: the new, all-aluminium 1750 Turbo Petrol engine; the latest-generation “Alfa TCT” dry twin clutch transmission and the Alfa DNA driving mode selector – now with a new “Race” mode.
A Carbon-fibre monocoque built using Formula 1-derived technologies
Carbon-fibre was chosen for the one-piece monocoque due its high levels of structural rigidity and exceptionally low weight – just 65kg – and is built using sophisticated Formula 1-derived technologies, evolved especially for Alfa Romeo for series production of up to 1,000 units per year. SMC (Sheet Moulding Compound), which is lighter than both steel and aluminium, is used for the bodywork, and the thickness of the glass has been slimmed down by 15% to help reduce the Alfa Romeo 4C’s overall weight, which is 895kg, along with a 40:60 front-to-rear weight distribution.
Power comes courtesy of a new four-cylinder turbo engine which, thanks to its aluminium block, is 22kg lighter than the engine that powers the Alfa Romeo Giulietta QV. Turbo-charged and with direct injection, this new 1750 Turbo Petrol unit sets new torque and specific power records for this size of engine, at over 200Nm- and 137hp-per-litre respectively. Its maximum power output is 240hp at 6,000 rpm while its maximum torque output is 350Nm (258 lb ft), available between 2,100 and 4,000 rpm, with 80% of its torque available from just 1800 rpm.
The all-new Alfa Romeo Romeo 4C goes on sale in the UK in October priced from £45,000 on the road, with first deliveries expected early in 2014. In total, global production for the Alfa Romeo 4C is limited to just 3,500 units.
