The Alfa Romeo 4C is a small, lightweight, rear wheel drive sports car, similar in size to the Alfa Romeo MiTo. It uses a carbon fiber tub, front and rear crash box, and hybrid rear frame mainly out of aluminum to keep its weight at 895 kilograms (1,973 lb); 995 kilograms (2,194 lb) in the United States. The 4C will be the first mass-produced Alfa Romeo car for re-entry into the US market by 2014.

Alfa Romeo 4C Concept (2011)

Alfa Romeo 4C Concept is a two-seater, rear-wheel drive coupé with technology and materials derived from the Alfa Romeo 8C Competizione, with 1750 turbo petrol engine with direct injection, the "Alfa TCT" twin dry clutch transmission, the Alfa DNA dynamic control selector.
The 4C concept version unveiled in the 81st Geneva Motor Show in March 2011, followed by Mille Miglia 2011 parade, Goodwood Festival of Speed 2011, 2011 Frankfurt Motor Show.
It was displayed first time outside in Concorso d'Eleganza Villa d'Este in 2012. Compared to the production version, it's very similar, with the biggest differences being front lights, side vents and mirrors.

Awards

The Alfa Romeo 4C Concept was voted the 'Most Beautiful Concept Car of the Year' award by the readers of German magazine Auto Bild, and won the Auto Bild Design Award 2011. It was awarded the "Design Award for Concept Cars & Prototypes" by referendum of the public in Villa d'Este.

Initial release

The vehicle was unveiled in 2013 Geneva Motor Show, followed by 2013 Essen 'Techno Classica', Goodwood Festival of Speed 2013, Moscow Raceway, 2013 Frankfurt Motor Show.
Ordering of European models began in October 2013 at Alfa Romeo dealerships in Europe.
US model includes extra bracing and strengthening required to meet U.S. crash regulations (including aluminium inserts in the carbon fiber chassis), resulting in 100 kilograms (220 lb) weight increase.
Sales of the US models of Alfa Romeo 4C were delayed until the second quarter of 2014.

4C Spider

Alfa Romeo officially announced a Spider version of the 4C at the 2014 Geneva Motor Show, that comes with a manual removable hard top. The engine is the same as the Coupe version but 4C Spider has different external parts like the headlights, exhaust and engine hood. Alfa admits it has had to make some strengthening tweaks to the 4C to cope with being decapitated, with the net result being a 60 kg (132 lb) weight increase.

Body and chassis

4C Concept

The car was designed by Alfa Romeo Centro Stile (Style Centre) and developed by Alfa Romeo. The carbon fiber tub is produced by TTA (Tecno Tessile Adler) in Airola, a joint venture between Adler and Lavorazione Materiali Compositi (Lmc). The body will not be made entirely of carbon fiber, with the front and rear frames being aluminium. This increases the weight to around 900 kg (2,000 lb).
The chassis of the car weighs only 65 kilograms (143 lb) and is a single carbon fibre body, just like that in supercars. Outer body is made of composite material which is 20% lighter than steel body, stability is comparable to steel and better than aluminium.

Powertrain and performance

4 cylinder 1750 TBi (direct injection turbo)
The 4C uses a new all-aluminium 1.75 L (1,742 cc) 240 horsepower (180 kW) at 6000 rpm inline 4 cylinder turbocharged engine. The engine has been designed for minimum weight, and will probably also appear in the 159 replacement, the Giulia. The engine CO2 emissions are 157 g/km and combined fuel consumption 6.8 L/100 km (42 mpg-imp; 35 mpg-US). 0–62 miles per hour (0–100 km/h) acceleration is achieved in 4.5 seconds and the top speed is 258 km/h (160 mph), the power-to-weight-ratio being just 0.33 hp/kg (8.22 lb/hp). Journalist of the Quattroruote car magazine demonstrated how the 4C accelerates from 0–100 kilometres per hour (0–62 mph) faster than 4.5 seconds. In race mode, with left foot on the brake pedal, if you pull the right shift paddle engine will rev at 3500 rpm, but if you pull also the left paddle engine will rev as 6000 rpm and 0–100 kilometres per hour (0–62 mph) time will go down to 4.2 seconds.
Alfa Romeo has also confirmed a new 1.8 litre, 300 PS (221 kW) engine, which may appear in the 4C.
Italian car magazine Quattroruote published the lap time of 4C around Nurburgring. It managed to do it in 8:04.
The 4C is equipped with six speed Alfa TCT Dual Dry Clutch Transmission, and can be operated via gearshift paddles on the steering wheel. It also has an Alfa 'DNA' dynamic control selector which controls the behavior of engine, brakes, throttle response, suspension and gearbox. In addition to the modes already seen in Giulietta, the 4C has a new "Race" mode.
