Following last week’s announcement, Autodelta officially unveiled today the Alfa Romeo 159 J4 2.2 C which becomes the company’s third member of the bespoke J-series range, joining the Brera J5 3.2 C and Spider J6 3.2 C in the Autodelta line-up. Available for order from July 1st, the 159 J4 2.2 C features a 2.2-liter engine equipped with a Rotrex C30-74 supercharger and a specifically-developed bespoke ECU system that boosts output from the standard 185Hp to 245Hp while peak torque is raised from 230 Nm to 290Nm. 
Strangely, Autodelta has yet to reveal performance figures but expect a sub-7,0 sec time for the 0 to 100km/h (62 mph) sprint. To complement the power increase, Autodelta has enhanced the 159 chassis dynamics by reworking the suspension that incorporates new dampers and springs and by adding a limited slip differential (LSD) that works on the front wheels. The J4 2.2 C also features uprated brake discs, which are additionally perforated at the front and rear, while the car sits on 19-inch alloy wheels wrapped in high-performance Dunlop Sp Sport Maxx GT tires (245/35 ZR19). -ContinuedDespite these additions, Autodelta supports that the J4 2.2 C is actually 5kg or 11 lbs lighter than the standard production Alfa 159 2.2 JTS thanks to the ultralight OZ alloy wheels and the new exhaust system and suspension components.
Design-wise, Autodelta has developed an tasteful bodykit that includes front splitter, rear apron and side skirts, with the front and rear apron sections designed to fit the standard bumpers of the production Alfa 159.
