Alfa Romeo continues to tease its upcoming 4C sports car by releasing production information ahead of its UK debut at Goodwood next month.
With a kerb weight of just 895kg, Alfa has certainly gone all out to achieve the lightest methods of construction for the 4C. The monocoque chassis is made out of carbon-fibre and weighs just 65kg. As well as lightweight materials, Alfa has also sought Formula 1 production methods to allow more than 1,000 units to be made each year.
The rest of the body is largely made of aluminium; it's found in the roof as well as the front and rear ends. Even the brake discs have gone on the aluminium diet, with 2kg shaved off each disc.
As well as changes in its construction, Alfa has slimmed down the windows, creating glass that is 10 per cent thinner than those traditionally fitted to cars. The windscreen has been shaved down to a mere 4mm.
Other materials used in its production are low-density SMC (Sheet Moulding Compound) and polyurethane for its bumpers and wings. All this effort gives a weight-to-power ratio of 4kg/hp from the 4C's turbocharged, 240hp, 1.75-litre engine. Linked to Alfa's six-speed TCT (twin dry clutch transmission), 0-62mph is reached in just 4.5 seconds and top speed is said to be 160mph. Its lightweight construction also contributes to an impressive 42mpg fuel economy figure.
The new 4C will tackle Goodwood's famous Hill Climb course at the Moving Motor Show on 11th July. The car can then be seen on display at the Festival of Speed Event that runs from 12th-14th July.
