In İzmir, Türkiye, urban features like narrow, winding streets present unique challenges for public transportation. The city's primary public transport provider ESHOT General Directorate comprehensive service across its 430 routes means constantly adapting to these geographical realities while prioritizing passenger and driver comfort. To effectively navigate these urban corridors and meet the growing population's desire for public transport, ESHOT identified a critical need for more agile vehicles.
"In our job, we spend the day navigating city traffic and stopping frequently at stops. With automatic transmissions, I don’t have to worry about changing gears; pressing 'D' is enough. This allows me to focus more on the road and traffic, making it easier to drive my vehicle more smoothly and comfortably. I also feel less tired at the end of my shift. The automatic transmission even helps with stress management for drivers in city transit."

Allison transmissions are engineered for urban enviornments
Designed specifically for city buses operating in stop-and-go conditions, the Allison T 2100 xFE™ fully automatic transmissions deliver superior performance and efficiency. Unlike manual or automated manual transmissions (AMTs), which can suffer from power and torque interruptions during gear shifts, Allison's torque converter ensures a smooth, continuous flow of power to the wheels.
The Allison T 2100 xFE™ transmission system, suitable for city buses up to 172 kW (230 horsepower), incorporates advanced features to optimize both performance and fuel economy:
- Patented Torque Converter: Smoothly multiplies engine torque, delivering enhanced launch and acceleration.
- xFE Fuel-Saving Technology: Features refined internal gear ratios specifically engineered to minimize fuel consumption in urban cycles.
- FuelSense 2.0® Software: Intelligently controls shifting strategies, ensuring optimal gear engagement for maximum efficiency.
Effective and Efficient Operations
From an operational standpoint, the Allison automatics contribute to reduced maintenance and repair costs. ESHOT officials noted, "Fully automatic transmissions provide fuel efficiency by optimizing gear shifts. They also prevent high fuel consumption caused by variations in driving styles and reduce the likelihood of breakdowns which might occur due to driving inconsistencies. Allison transmissions contribute to decreasing maintenance and repair costs by using a hydraulic torque converter instead of the wear-prone clutch system found in manuals and AMTs. This eliminates the need for costly and time-consuming clutch repairs and replacements. Allison transmissions offer a more efficient operational lifespan with only periodic fluid and filter changes."
