宇通 ZK6180HGH Yutong ZK6180HGH
編號 Class：YL
掛接巴士首次出現於澳門源於二零一六年四月，在新時代要求下，宇通車廠將兩架分別長十三米配三門車身的三軸單層巴士，以及長十八米以掛接形式出現的單層巴士，運到澳門以作路面測試，從而評估日後購入同巴士之可能性，由於兩架巴士都屬左軚設計，故並未有用作載客營運測試。在是次測試之後，新時代認為掛接巴士雖然車長十八米，但即使面對澳門街的狹窄環境，仍能應付自如。
不過，當掛接巴士成功落戶澳門時候，卻不是由新時代寫下這歷史新一頁，而是新福利。這架由宇通製作的ZK6180HGH巴士，除了成為澳門有史以來最長，最高載客量的巴士型號外，同時創下抵澳之後最快登記出牌的紀錄。新福利於二零一七年十一月二十九日接收這架宇通掛接巴士，隨即於同日被安排進行驗車，並於同年十二月二日登記出牌。儘管不需一星期已獲發行車牌照，但掛接巴士未有立即投入服務，而是被用作訓練車長，直到二零一八年一月六日才正式安排於繁忙時間，行走住返蝴蝶結谷大馬路(石排灣)及關閘之間的51路線，以應付龐大的客量需求。
新福利的宇通ZK6180HGH巴士，採用與台灣台中市的ZK6180HG掛接巴士相同的車身，至於機械配搭方面，宇通掛接巴士配備有歐五排放標準的康明斯引擎，配合ZF全自動波箱，而將前後兩節車箱連在一起的鉸接盤，由同樣來自德國的HÜBNER提供。另外，宇通在這架掛接巴士兩側玻璃窗設有爆破裝置，遇上緊急事故時，車長只要按下駕駛室上的按鈕，就會打破車窗以供乘客逃生，這個裝置亦見於隊中另一款宇通巴士ZK6128HG上。至於車廂配置一如新福利其他新車，有仿木紋地板膠及USB插頭供乘客為手提裝置充電。
目前除了這架宇通掛接巴士外，新福利以至澳巴暫時都未有計劃再引進同款巴士，而從這架ZK6180HGH服務時間及行走路線，似乎營運商對掛接巴士是否適合澳門營運環境，仍要再觀察多一段時間。除了上述的51線，宇通掛接巴士曾經支援25AX及51X特別路線。
In Apr., 2016, New Era requested Yutong sent a pair of demonstrators to Macau, a 13m 3-axles single decker and a 18m articulated bus, to test their suitability of the Macau operation environment. As both demonstrators were left-hand drive, they never used on revenue service for evaluation. The evaluation result of the articulated bus was satisfactoried even under the narrow road conditions of Macau.
The very first articulated bus for the Macau public bus market, however, was introduced by Transmac. The model of the articulated bus was Yutong ZK6180HGH and it was not only the longest public bus with highest carrying capacity, but also the one with the shortest time awaiting for registration. After delivery on 29 Nov., 2017, it was immediately sent for examination and first registered on 2 Dec., 2017. Transmac first arranged this articulated bus as driver trainer until 6 Jan., 2018, supporting the high demand route 51 linking between AV. Vale Das Borboletas / Terminal and Portas do Cerco during rush hours.
The appearance of Transmac Yutong ZK6180HGH was same as those running in Taichung and it was powered by a Euro 5 Cummins engine with ZF fully automatic gearbox. The articulation system linking the front and rear portion was supplied by HÜBNER from Germany. Same as the ZK6128HG in the fleet, an emergency glass breaking system was installed and wood-effect floor and USB chargers can be seen on the articulated bus as other new buses.
This articulated bus still unique in Macau and neither Transmac nor T.C.M would place further order in the near future. It was still need sometime to prove whether articulated bus is suitable for the operation environment of Macau. Instead of the schedule route, this Yutong ZK8180HGH also once supported route 25AX and 51X.
