The Abarth 124 rally 2019. The Spider with the scorpion badge has been revised to keep defending its leadership status in rallying

 

  • The spider with the scorpion badge has been revised, implementing the experience gained over the first two racing seasons and the continuous development work of the Abarth team.
  • Over 5,000 kilometres of testing were performed to improve performance, handling, and make the car even easier to tune.

 

Many aspects of the Abarth 124 rally 2019 have been addressed with the objective of bettering the time per kilometre in special stages. This goal was achieved by the Abarth engineers by means of targeted operations on the main mechanical components as well as the engine electronics, the transmission-gearbox and the setup.

 

Plenty of data was collected during the first two racing seasons of the 124 rally in addition to the practical field experience. The continuous development work carried out by the Abarth engineering team and, last but not least, the major contribution of test driver and pilot Alex Fiorio complemented the experience of the previous two years of racing. A further 5,000 kilometres of simulated tests were clocked up, in addition to the distance already travelled in actual rallies, utilising the same roads where many of the challenging special stages are run.

 

The goal was to provide customers with a better performing race car, which is simpler to tune and at the same time easier to drive, perfect for professional and gentleman drivers alike, who in the spider seek the typical drifting pleasure of rear-wheel drive cars in rallies, in addition to performance at its best.

 

The main operations concerned the following areas:

 

Engine - The main job was to improve delivery by means of targeted actions to make torque curve more linear. The torque curve is today fuller at all RPMs, particularly when power from low speeds is needed, which is a typical when coming out of hairpin bends at a low rpm for instance, while making driving more effective and simpler, allowing non-professional drivers to perform at their best. The power delivery improvement is the result of a careful calibration which promotes smoothness and prompter throttle response.

 

Transmission - The transmission department focused on the differential, with a new locking calibration and four mappings (High/Medium/Low Grip, Wet) on the Traction Control System, which can be quickly selected by the driver on the steering wheel and which adjust engine torque delivery to maximise it according to grip conditions. In this way, the driver can intervene quickly according to their needs by changing the response of the car to the changing grip conditions, fast and precisely, on any terrain.

 

Gearbox - The gearbox was also targeted to improve manoeuvrability and shifting speed. In particular, the pneumatic actuator was adjusted to allow faster gear engagement in acceleration and more calibrated, smoother downshifting to prevent rear axle locking.

 

Nevertheless, rear wheel locking, typical of rally driving, is possible by using the hand brake, which is even more effective as a result of the optimised transmission declutching and its subsequent calibrated insertion in traction for prompter take-offs.

 

Setup - Having a good feeling with the car and being able to adjust the setup is crucial for drivers. For this reason, Abarth worked on all components improving the grip on tarmac and providing a kit for use on gravel roads.

 

The antidive effect was also revised. The car now has a positive pitching effect while braking which provides better feeling to the driver and facilitates the progressive braking while improving cornering at the same time. All specific aspects were further developed to achieve an optimal overall result, which drivers can also customise to suit their own driving style and the type of course.

 

Gravel kit - The development work also focused on the car setup for gravel roads by creating a special kit which includes all the components needed for taking on this type of surface. A specific gravel road kit is now available which includes ground clearance increased by 40 mm, with a consequent increase in the suspension travel, needed to maintain constant contact between tyres even on the rougher terrain and for better traction and road holding. The gravel road kit also includes brake discs compatible with specific 15-inch alloy wheel (instead of 18-inch wheels used on tarmac) to reduce the unsprung weight to optimise grip on particularly rough terrain.

 

The tarmac and gravel tyres are the same size as required by R5 (and WRC) category regulations to be able to take advantage of the wide range of commercially available compounds.
