They still operate and maintain nearly 800 units, with an average age of 12 years and mileage of 13 million km. Many operators like this bus because it's versatile, easy to maintain, and fuel-efficient. Although it may be small, it's TM440 turbodiesel engine can produce 340hp, making top speeds of up to 100mph(160kph).
