As you may know already, the Alfa Romeo 4C uses an all-aluminum 1750 cc four-cylinder engine that delivers 237 hp and 350 Nm (258 lb-ft) of torque. Still, Lazzarini Design decided that the engine is not powerful enough and it replaced it with a 4.3-liter V8 engine from Ferrari, equipped with twin-turbochargers from Hennessey Performance.
The new engine delivers staggering 738 hp and 720 Nm (532 lb-ft) of torque.
Due to the impressive output delivered by the engine, the vehicle also received a new body kit that consists of a redesigned front bumper, enlarged front and rear fenders, new side sills, a big rear wing, and a new rear bumper with integrated active air diffuser and central exhaust tailpipes.
To keep the weight below 1,000 kg, the vehicle receives magnesium rims, carbon fiber hood and roof, an engine hood made out of Plexiglass and carbon-ceramic brake discs. According to Lazzarini Design, their Alfa Romeo 4C Definitiva will cost around 250,000 euros or $311,000.
A truly unique design, the 4C has remarkable agility due in turn to its size. At just 4m long, 2m wide, 1.18m high and revelling in a wheelbase of under 2.4m, the 4C is truly a car designed for the urbanite.
Alfa Romeo Centro Stile created the 4C and part of the development plan was to embrace a sportier aspect and ensure both the aesthetics and the performance were enhanced.
In order to achieve this, the designers and engineers worked hand-in-hand in carefully smoothing the edges, trimming excess waste and delivering vehicles which are as aerodynamic as a missile.
Delivering a technological marvel of beauty and sophistication, the team at Alfa Romeo did in no way forget to create one which was also functional and efficient.
Designed to handle fast corners, the engineers went to great lengths to create enough downforce for the 4C to do so.
The 4C's engine is visible through the rear window and aids the bearing of the vehicle by pushing the weight down at the back, stabilising it and showing off Alfa Romeo's hard work and design in the process.
Increased mass on the rear of the 4C is lit by a group of rear lights clustered around the plate holder. To cool down the intercooler and the engine, side air intakes have been fitted, from which it is possible to see how the team at Alfa Romeo have given the 4C a more dynamic, athletic appeal. These lines extend from the intakes travel down to the front of the 4C and plunge into the redesigned face which as always carries the famous 'Trefoil', which includes the symbolic “V” which extends up out of the shield up along the bonnet and into the parallel air intakes.
The plate holder is a key part of the rear of the vehicle. By not only serving to protect the light cluster, it also has a separate task, including one which at first isn't immediately apparent. What the designers at Alfa Romeo have achieved is to create something which is purely aesthetically pleasing but also pleasantly functional. The lines which are next to the plate holder not only give the appearance of movement they also will protect the lights from any additional damage should the vehicle be struck from behind.
Final change to the rear of the vehicle was to ensure there was no drag when it came to the tail. Rigorously tested using wind tunnels and by computer-aided design, the team at Alfa Romeo looked at the rear upper and lower profiles, the spoiler and the air outlets making sure they were as tight as possible to the vehicle and did not cause any drag.
The four colours of the 4C, black, grey, red and white mirror the tenacity and drive of Alfa Romeo's core and new technology has meant the 4C can be layered with as many as three different colours. However as any Alfa Romeo fan might expect, Competizione Red remains as the heart and soul of the brand and the most popular choice, due to its vibrancy, allure and the way the colour falls on the 4C's soulful lines.
