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.
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.
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.
The production car was unveiled at the 2013 Geneva Motor Show, followed by 2013 Essen 'Techno Classica', Goodwood Festival of Speed 2013, Moscow Raceway, 2013 Frankfurt Motor Show.
The bare '4C000' chassis was also shown at the 2013 Geneva Motor Show.
Ordering of European models began in October 2013 at Alfa Romeo dealerships in Europe.
As part of Alfa Romeo 4C launch, Alfa Romeo Style Centre and Compagnia Ducale designed a 4C IFD (Innovative Frame Design) Bicycle, inspired by the Alfa Romeo 4C coupé. The vehicle went on sale in December 2013 and marketed in Europe, Asia and America.
Production of 4C began May 2013 at Maserati's plant in Modena, with an expected production of up to 2500 units per year. It will be the first mass-produced Alfa Romeo car for re-entry into the US market.
Production of Alfa Romeo 4C was originally estimated to be over 1000 units per year, with an upper limit of 3500 units per year, depending on the quantity of carbon fiber chassis that can be built by the supplier Adler Plastic. Within the 3,500-unit quota, 1,000 units of which are earmarked for Europe.
Delivery of European Alfa Romeo 4C Launch Edition took place at Balocco (Vercelli, Italy) Test Centre, with vehicles delivered to Pierluigi De Silvestro (Switzerland), Philippe Walch (France), Carlos Diniz (Germany), Aldo Mariani (the Netherlands) and Stefano Zanotti (Italy).
Body and chassis
The car was designed by Centro Stile Alfa Romeo (Style Centre) and developed by Alfa Romeo. The chassis is composed of a central carbon fiber tub, with aluminium subframes front and rear. The carbon fiber tub is produced by TTA (Tecno Tessile Adler) in Airola, as a joint venture between Adler Plastic and Lavorazione Materiali Compositi. The carbon fiber components that make up the chassis are cut using CNC technology.
The chassis of the car weighs 65 kilograms (143 lb) (Spider's chassis weights 107 kilograms (236 lb)) and is a single carbon fiber body, similar to the body of many supercars. The outer body is made of a composite material (SMC for Sheet Moulding Compound) which is 20% lighter than steel. The stability is comparable to steel and better than aluminium.
The 4C employs double wishbone suspensions at the front and MacPherson struts at the rear. The resultant weight distribution is 38% on the front and 62% on the rear axle. Wheels and tyres have different diameters and widths front and rear: 205/45 R17 front and 235/40 R18 back as standard, with optional 205/40 R18 and 235/35 R19. Both wheel options come equipped with Pirelli P Zero tires. The 4C uses vented disc brakes on all wheels; Brembo 305 millimetres (12.0 in) on the front and 292 millimetres (11.5 in) on the rear. The car can stop from 100 km/h (62 mph) in 36 meters. To save weight and increase steering feel, the 4C has no power steering.
Powertrain and performance
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's 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 the engine will rev to 3500 rpm, but if you also pull the left paddle the engine will rev to 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.
The 4C is equipped with a 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.
|Top speed||258 km/h (160 mph)|
|0–100 km/h (0–62 mph)||4.5 seconds|
|Displacement||1.75 L 1,742 cc (106.3 cu in)|
|Power||240 PS (177 kW; 237 hp) @ 6,000 rpm|
|Torque||350 N·m (260 lb·ft) @ 2,100 rpm|
|Lateral Acceleration||1.1 g|
Launch Edition (2013–)
The 4C Launch Edition is a limited and numbered edition, unveiled at the vehicle's launch at the 2013 Geneva Motor Show. 400 examples were reserved for Europe, Africa and the Middle East, 500 for North America and 100 for the rest of the world. The vehicle comes in a choice of two body colours (Alfa Red or matt Carrara White). Distinguishing features of the Launch Edition are carbon fiber trim (including headlight housings, spoiler and door mirror caps), rear aluminium extractor with dark finishing, Bi-LED headlights, dark painted 18-inch front and 19-inch rear alloy wheels, additional air intakes on the front fascia, red brake calipers, racing exhaust system, BMC air cleaner, specific calibration for shock absorbers and rear anti-roll bar,leather/fabric sports seats with parts in Alcantara and a numbered carbon fiber plaque. Alfa Red coloured cars get matching red stitching on the steering wheel, handbrake, mats, handles and sports seats.
In Europe the vehicle went on sale for 60,000 euros including VAT.
North American version
The US version of 4C was introduced in 2014 New York International Auto Show and the first 100 4C's will be shipped to the U.S. by late June or early July, with a total of 850 to be shipped by the end of this year. The 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. This version has also new headlamps similar as seen before in 4C Spider version.
Alfa Romeo 4C Spider
The Spider version of the 4C was previewed showing a pre-production prototype at the 2014 Geneva Motor Show. The engine is the same as the Coupé version but the 4C Spider has different external parts such as the headlights, exhaust and engine hood. Alfa admits it has had to make some strengthening tweaks to the 4C to cope with the removal of the top, with the net result being a 45 kg (99 lb) weight increase (dry weight 940 kg). Top speed is quoted at 257 km/h (160 mph) and acceleration at 4,5 seconds to 100km/h. Novelty to 4C range is an option of yellow colour for Spider.
