Alfa Romeo's promotional campaign for its upcoming 4C sports car continues this week, with details of the hot coupe's production process.
Much is already known about the 4C, of course. Power is provided by a mid-mounted 176kW and 350Nm 1.75 litre turbocharged engine matched to a dual-clutch transmission, promising a 0-100km/h time of just 4.5 seconds.
The new coupe is made with liberal amounts of aluminium, sheet-moulding compound, carbon fibre and high-tensile steel, and Alfa promises a dry weight of just 895kg - making for a 4kg/hp power-to-weight ratio.
Breaking it down, Alfa says around 25 percent of the 4C's construction is of carbon fibre - including the car's full carbon monocoque, which on its own weighs just 65kg.
You'll find aluminium in the 4C's structural areas, including the front and rear frameworks and the roof reinforcement cage, along with elements in the braking package. Thanks to this, the weight of each brake disc has been reduced by nearly 2kg.
The low-density and high-resistance Sheet Moulding Compound material is used throughout the 4C's body, reducing weight by a further 20 percent compared to regular sheet metal.
Injected polyurethane has been used for the bumpers and wheel guards, again reducing weight by around 20 percent compared to steel.
Even the glass in the 4C's windows is lighter than most, thanks to being 15 percent thinner than in a standard passenger car.
Manufactured by Fiat stablemate Maserati, no more than 3500 4C cars will be built each year, with a full 1000 of them already scheduled for European markets.
An Australian launch is set for early 2014.
