“4C” and the Legacy of Alfa Romeo
The Alfa Romeo 4C Spider name recalls the brand’s great sporting tradition. The acronyms 8C and 6C in the 1930s and 1940s distinguished racing and road cars fitted with powerful eight- and six-cylinder engines. Like the award-winning 4C, the all-new Alfa Romeo 4C Spider model’s designation is a return to “the great Alfa Romeos” and continues this tradition with the innovative all-aluminum 1750 turbocharged, intercooled, direct injection, four-cylinder engine, delivering an impressive 136 horsepower per liter.

With seating for two, panoramic views and the soundtrack of an Italian performance-tuned engine and exhaust, Spiders are among the most exhilarating experiences in motoring – and represent the very core of Alfa Romeo’s DNA and heritage.

The 4C Spider draws from a bloodline that includes some of the most purpose-built performance models, which illustrate lightness and efficiency with undeniable Alfa Romeo style – the aluminum-bodied 8C 2900 B Touring (1938); the 1900 C52 “Flying Saucer” (1952), which could exceed 140 mph (230 kph); and most notably the legendary 33 Stradale (1967), with its mid-engine and magnesium alloy and steel tube chassis “clothed” by groundbreaking styling, which is functional and distinctly Italian. And now it’s the 4C Spider’s turn to deliver the driving thrill, performance and unforgettable emotion that only an Alfa Romeo Spider provokes.

Italian style
Continuing the groundbreaking theme of technology, performance and Italian style, the all-new 2015 Alfa Romeo 4C Spider builds upon the brand’s journey, which was embarked upon with the 8C Competizione (2008), 8C Spider (2009), 4C (2015), and most recently, the 4C Spider Concept, which debuted at the 84th International Geneva Motor Show.
Inspired by the 33 Stradale, the all-new Alfa Romeo 4C Spider transcends this legendary racecar’s mid-engine body forms and follows its purposeful and lightweight performance tradition with sheet-molded compound (SMC) composite panels forming its seductive Italian design, and “clothing” its state-of-the-art carbon fiber monocoque chassis and all-aluminum 1750 turbocharged, direct-injected engine.

Leading from the 4C Spider’s windshield and down the hood are two muscular hood forms, which naturally conclude at the signature Alfa Romeo shield-shaped grille and emblem. Together with the two side air intakes designed in the front fascia, the 4C Spider forms the famous “Trilobo” within which the iconic logo is placed – and a significant facet of Alfa Romeo’s distinctive design.

Performance-focused cockpit
The all-new Alfa Romeo 4C Spider’s cockpit is inspired from racing; purpose built with only the essential driving components stylistically integrated.

The Alfa Romeo 4C Spider features two composite-framed sport seats with standard leather and an exposed carbon fiber monocoque that exemplifies its race-inspired technologies. Furthermore, a driver-oriented cockpit with flat-bottom, leather performance steering wheel with paddle-shifters and aluminum pedals speak to the brand’s racing spirit. For an upscale look, the fully wrapped premium-leather interior with accent stitching is standard on the Alfa Romeo 4C Spider. For an added touch of exclusivity and technology, unique carbon fiber vent surrounds and other carbon fiber trim pieces are available as part of a new Carbon Fiber Trim Package. Highlighting the use of advanced technology is a 7-inch full-color driver information display (DID) cluster, which displays vehicle information through high-impact graphics to keep the driver focused on the road, or track, ahead.

An array of colors
Adding to the excitement of owning an Alfa Romeo are the personalization options that each client can select.

Seven exterior colors are available for the 4C Spider, and include: Rosso Alfa (Red), Black, White, Basalt Gray Metallic, Rosso Competizione Tri-coat (Red), Madreperla White Tri-coat and all-new Giallo Prototipo (Yellow).

Complementing the 4C Spider’s exterior are six interior combinations, which include two seat material choices: Black leather with Red accent stitching, Red leather with Black accent stitching, new Black leather with Giallo accent stitching, and exclusive to the Track Package – Black racing leather seats with microfiber inserts and Red or Yellow accent stitching.

All-aluminum 1750 turbocharged engine with direct injection
The engine is the “beating heart” of any Alfa Romeo, and for the all-new 4C Spider, it beats to an innovative, all-aluminum 1750 turbocharged and intercooled engine with dual (intake and exhaust) continuous variable-valve timing that delivers 237 horsepower – or an impressive 136 horsepower per liter.

To ensure exceptional performance and drivability on the racetrack or city streets, the 1750 turbocharged engine features cutting-edge technologies. High-pressure direct-injection (2,900 psi / 200 bar) with multi-hole fuel injectors provide a more even spray. To increase performance, while reducing oil consumption and emissions, the cylinder head inlet ducts have an optimized design, while cylinder liners are made from thin cast-iron. The addition of an electric thermostat helps the 1750 turbo engine reduce warm-up times and tailpipe emissions. Minimizing vibration at higher engine speeds, the engine’s crankshaft features eight counterweights. Last, intake and exhaust systems are optimized for Alfa Romeo 4C Spider’s mid-engine layout.

A new generation turbocharger features a pulse-converter exhaust manifold to exploit pressure waves and boost torque at low-engine speeds. A wastegate valve adjusts turbo pressure and improves the engine’s efficiency. Advanced turbo technology enables the Alfa Romeo 4C Spider to maximize torque at low engine speeds and deliver more response to driver input by increasing combustion efficiency and turbine speed, all while eliminating turbo lag. As a result, torque delivery is instantaneous, with a peak of 258 lb.-ft. (350 N•m); 80 percent of which is available at only 1,700 rpm.
