The Autodelta 159 J4 2.2 C will become the third member of the exclusive bespoke J-series range, joining the Brera J5 3.2 C and Spider J6 3.2 C in the Autodelta line-up when the high performance sports saloon’s order book opens on July 1st. 18 months of intensive research and development and Autodelta is proud to present this new car. Pushing the dynamic envelope of Alfa Romeo’s to the edge to create sports cars that thrill the driver is our deep seated motivation, and with the J4 2.2 C we believe we have raised the bar even further in every field and created our finest project to date.

Just like the other two now-established members of the J-series range, the integral theme of the Autodelta 159 J4 2.2 C is to continue a long standing tradition of applying forced induction principles to develop nothing less than the very ultimate expression of high performance motoring. The Autodelta 159 J4 2.2 C once again makes strides across the sphere of engineering excellence, and applies the results of an intensive 18 month research and development programme, led by Head of R&D Sergio Truzzi, to Alfa Romeo’s advanced direct injection JTS, making us the only company in the world to develop a forced induction solution for this power unit.

With the commercialisation of the supercharged Alfa 159 2.2 JTS we have taken a dual approach, offering two solutions to satisfy all demands. The excellent all-round capabilities of the Alfa 159 architecture blossom into life when harnessed to our new supercharging upgrade. As such we are offering the 159 2.2 C supercharged package at this level, commercialised at a highly competitive price, and for the many customers who will desire to maximise the dynamics and performance of the car, we have developed the usual enhancements – to the driveable edge - in every area, which will be offered as the J4 2.2 C option. Thus the driver has two choices; he can experience full Autodelta performance wrought to the 159 at an affordable price, or take his car to the ultimate limit in every department by choosing the full range of options that suit his driving requirements. As usual though each Autodelta car will be built uniquely, with every customer’s individual demands met and exceeded by our engineers – a challenge we always thrive on, and never fail to meet. Although the J4’s 0-100 km/h sprint is more rapid now, one of its more capable abilities of this sports saloon is the in-gear acceleration and flexibility which will impress those who get behind the wheel.

What we have created is a car to satisfy even the most demanding of drivers, a car that simply immerses you in its stunning dynamic capabilities, and that allows you to experience everything that Alfa Romeo has built its historic brand values on. But true to our tradition, and to satisfy our customers’ requirements, this is also a practical ‘user-friendly’ sports saloon that is just as driveable in the morning traffic jam as it is when let off the leash on one of Europe’s finest roads.

Alfa Romeo’s history is littered with fabulous, ground breaking sports cars that have reshaped automotive thinking time and time again. As such when seeking inspiration the possibilities are virtually unlimited for our team. However for with this project one car stood out especially, and so with the 159 J4 2.2 project Autodelta really wanted to capture the modern day spirit of the Alfa 156 GTA, one of the most revered ‘hot saloons’ of the decade, and a sports car that we have enjoyed rewarding success in tuning. This evocative car was a benchmark for us, however seeking more refined comfort and improved, updated dynamic behaviour.

Supercharging Alfa Romeo tradition and a offers the ultimate performance solution

Under the sleek, swaged bonnet of the Autodelta 159 J4 2.2 C beats the muscular heart of this powerhouse: a supercharged version of Alfa Romeo’s impressive 2.2 JTS direct injection petrol engine, the first production application of forced induction to this robust engine. The incorporation of the Rotrex C30-74 supercharger and a specifically-developed bespoke system boosts the 2.2-litre unit’s maximum power from the standard 185bhp up to 245 bhp, an increase of 60 bhp. Meanwhile, peak torque is raised from 230 Nm to 290Nm, giving the vibrant sports saloon an extra 60 Nm of torque.

Supercharging the 2.2 JTS engine and evolving the 159 J4 2.2 C package to perfection has been a long-term project for Autodelta, running alongside the development programmes to realise the J5 and J6. Autodelta’s engineering team was able to build on valuable experience gained when it became the first company in the world to apply forced induction to Alfa Romeo’s 2.0 JTS unit, as used in the 156 and GT models; and although it is an all-new unit in the Alfa 159, many of the important lessons learnt, and technical knowledge gained, were carried forward to the 2.2 JTS project.
