Conquering Coastal Curves: How Allison Transmissions Power Success on the Amalfi Coast

Discover how Sita Sud's upgraded fleet equipped with Allison transmissions helps deliver exceptional passenger transportation in Italy.

The Amalfi Coast, a UNESCO World Heritage site, is characterized by its steep cliffs, coastal waters and picturesque towns. It's also a formidable challenge for any vehicle tasked with navigating its famously narrow, winding roads and steep inclines. For Sita Sud S.r.l., a leading passenger transport company in Italy, ensuring efficient and comfortable journeys for both residents and the millions of tourists who visit the region is paramount. Their recent fleet enhancement, featuring six new Isuzu Novociti Life minibuses equipped with Allison fully automatic transmissions, is a significant step in providing excellent service in this unique environment.

The Challenge of Mastering the Amalfi Coast 

Imagine a daily commute where every turn is tight, every incline is steep and every moment of traffic can be unpredictable. This is the reality for public transport operators on the Amalfi-Ravello-Scala line, one of the most demanding routes on the Coast. Sita Sud needed vehicles that could:

  • Navigate with agility: The 7.8-meter Isuzu Novociti Life minibuses, capable of carrying up to 40 passengers, were chosen for their ideal size and maneuverability.
  • Perform reliably under pressure: Constant stop-and-go traffic and continuous elevation changes are unique challenges for this landscape. 
  • Optimize operational costs: Allison transmissions reduce vehicle downtime and excessive fuel consumption.


 


Discover how the adoption of these new vehicles has improved operational efficiency, reduced maintenance costs and increased comfort for both drivers and passengers.

 

Advanced Technology for Optimal Performance and Efficiency

The Isuzu Novociti Life buses are equipped with a Euro 6 Step E diesel engine paired with the Allison T3270 with a retarder ® and Extra Fuel Economy (xFE) automatic transmission. The Allison automatic transmission continuously transmits engine power to the wheels, allowing the minibuses to operate optimally, achieve higher average speeds and meet scheduled times. 

The Allison automatic transmission empowers the the Novociti Life to easily handle the Italian coastal routes, eliminating the need for manual gear shifting and ensuring smooth maneuvrability around the tight curves of the area. Additionally, the integrated hydraulic retarder offers greater efficiency during braking and deceleration phases. The retarder significantly reduces wear and tear of the service breaks.


    The Solution

    The solution was the introduction of four new Rosenbauer Panther 8x8 fire truck s, each equipped with Allison 4800R fully automatic transmissions. These transmissions were chosen for several key reasons:

    • Superior Acceleration: The vehicles can accelerate from 0 to 50 mph in about 20 seconds, thanks to the combined output of 1,430 horsepower from two Volvo D16 Euro 6 engines and the Continuous Power Technology and Torque Converter from Allison fully automatics.
    • Continuous Traction: The Allison transmissions provide continuous traction, allowing the 52-tonne trucks to be maneuvered swiftly and with precision, even in challenging conditions. 
    • Immediate Pump Operation: Because of the Power Take Off (PTO) integrated in the fully automatic transmission, the main operator can start the pump and roll immediately, providing more time to respond effectively to emergencies. 
    • Advanced Firefighting Equipment: The Panther 8x8s are configured with rapid attack hose reels and self-protection nozzles, enhancing the team's ability to handle a wide range of emergencies with precision and efficiency.
    • Minimal Maintenance: The robust design and fully hydraulic technology of the Allison transmissions ensures minimal maintenance, reducing downtime and operational costs. The integrated hydraulic retarder and power take-off have also proven to be very low maintenance.

    The timeline for the introduction of these vehicles was from late 2023 to early 2024, ensuring a smooth transition and immediate operational benefits. 

    "The Novociti Life impressed us with their ability to adapt to the complex terrain of the Coast, with a design and manoeuvrability that allow us to offer a faster and safer service. Furthermore, the Allison automatic transmissions make driving more intuitive and less stressful, enabling drivers to focus on the heavy traffic in the area."
    - Matteo De Martino, Technical Area Manager at Sita Sud.


    Innovation and Comfort for the Future of Transportation

    With the introduction of the new Isuzu Novociti Life minibuses with fully automatic Allison transmissions, Sita Sud reaffirms its commitment to providing efficient, reliable and comfortable public transport services, suitable for a beautiful but challenging landscape like the Amalfi Coast. The adopted solutions enhance operational performance and fleet management, laying the foundation for a more future-oriented public transport service.
