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.
