This Is How the Carbon Fiber Alfa Romeo 4C Is Made [Video] [Photo Gallery]
text size: A- A+
Alfa engineers start with the carbon fiber tub, which makes it very light. The whole car only weighs 895 kilograms, a featherweight compared to the heavy cars it rivals. Aluminum is then used for things like the door, roof and other structural components.
Weight has been pretty much an obsession for Alfa engineers, as even the humble brake discs were lightened by using aluminum for the bell.
After the assembly you see in the extensive photo gallery and the video below, Alfa tests each car for 40 km (26 miles) right as it comes off the line and onto a rolling road. Production of the 4C is strictly limited to about 3,500 units per year and we can kind of see why now.

In a word, awesome. This new compact sports car (the Alfa Romeo 4C coupe) you see here, in this article, is absolutely superb and also fantastic for my taste. The Alfa Romeo 4C coupe was unveiled in its final production version, at the 83rd Geneva Motor Show, in Geneva, Switzerland, on March 5th 2013. It has a lightweight carbon fibre monocoque chassis that weighs only 65 kg, a technological innovation used in motorsport - Formula 1, in particular - by the F1 single-seaters. It also uses different lightweight materials for the bodyshell like aluminum, high-strenght steel and Sheet Moulding Compound to keep its dry weight as low as possible (895 kg). The engine of this car is one the most powerful of its kind and still has the lowest fuel consumption and CO2 emissions figures of its class, which makes it the greenest compact sports car ever made in the world, and is, of course, a true masterpiece. It is a 1.75-litre turbocharged inline four-cylinder with direct petrol injection, double continuous variable valve timing and a revolutionary scavenging system that eliminates any turbo lag. This engine boosts out 240 bhp at 6000 rpm and 258 lb-ft (350 Nm) of torque and is associated to a 6-speed dual-clutch gearbox with "Launch Control" that transfers power and torque to the rear wheels. So, it is a true rear-wheel drive sports car. In terms of performance, it sprints from 0 to 100 kph in 4.5 seconds and hits a top speed in excess of 250 kph. Alfa Romeo 4C, one of the best compact sports car ever made on Earth. I love it.
