在城巴 49 部 11.3 米丹尼士 E50D 型陸續出牌的同時，新巴版本共 12 部車輛亦緊接抵港準備投入服務。在機械配置上，城巴及新巴車輛並無分別，只是新巴車輛配上椅背較薄的 Lazzerini CityLight 座椅，故上層可提供多一排右行座椅，令載客量較城巴同批車輛多 2 人。
回顧近年數字，新巴車隊數目有持續放緩的趨勢，主要原因與南港島線即將投入服務不無關係。新巴坐擁多條途經薄扶林道的路線，過往曾是南區進出港島北岸的咽喉，但隨著鐵路通車對新巴無疑芒刺在背。雖然南港島線（東段）迄今未動工無期，華富及置富花園一帶未來仍須依賴巴士服務出入，但對營運多條南區區內路線的新巴，伴隨南港島線而來的服務縮減壓力，不容忽視。
接替退役車隊
縱然如此，新巴旗下的 11.3 米富豪奧林比安、10.6 米及 11.3 米丹尼士三叉戟早於 1999 年出牌，至 2014 年已屆 15 年車齡，有必要引入更多中型長度巴士，填補有關車型作為中半山及南區的服務主力，故是次新巴再增購 11.3 米版車輛，有望紓緩退役車輛造成的短缺。
值得一提，本車型與城巴第 2 批後量產型 E50D（ #8361 起）相同，在左右車側均設有閉路電視鏡頭，加強監察行車表現及保障安全。隨後新巴於 2016 年再增購 40 部同款車輛，令本車型總數增至 52 部，並改配 Voith 波箱及更新上層座椅編排。其時此批車輛已轉用改良版車身，當中 #4076 以後車輛出牌時已在車頭加裝樹擋，至於較早引入的批次亦在 2017 年中陸續加裝，這亦令新巴成為全港首間擁有 3 種長度的配改良版車身丹尼士 E50D 型（ 11.3 米、 12 米及 12.8 米）。
現時此批巴士已陸續投入服務，並正活躍於東區區內、區外及中半山路線，及於繁忙時間支援東區過海路線。隨著 #4052 - 4091 陸續投入服務，#4040 - 4051 已調往南區路線服務。

The Alexander Dennis Enviro500 (previously known as the TransBus Enviro500) is a three-axle double-decker bus built by Alexander Dennis (formerly by TransBus) in the United Kingdom. It was unveiled in 2002 and is one of the Enviro-series bus models made by TransBus/Alexander Dennis.
The second generation Enviro500, also known as the Enviro500 MMC (MMC stands for "Major Model Change"), was launched in 2012, replacing the original version.
First generation (2002–2014)[edit]
The Dennis chassis for Enviro500 (also known as Trident E500[1]) was modified from the Trident 3. It can be fitted with Cummins ISMe335 Euro III engine (later Cummins ISLe340 Euro IV/Euro V engine which uses AdBlue to reduce emission of nitrogen oxides through selective catalytic reduction process), or ISM-330 engine for the buses delivered to North America, and coupled to Voith DIWA864.3E 4-speed or ZF 5HP602 5-speed gearbox. Later Voith DIWA864.5 4-speed gearbox, ZF 6HP602 6-speed gearbox and Allison B500R 6-speed gearbox became available and gradually became the standard configurations.
Initially only the 12-metre (40 ft)-long version of the Enviro500 was built, but in 2007 Alexander Dennis announced the production of the 12.8-metre-long version,[2] and an 11.3-metre-long variant followed in 2008.
Later Alexander Dennis developed the hybrid electric version of Enviro500, known as the Enviro500H, with GM-Allison's parallel hybrid drive system; it was unveiled in late 2008.[3][4]
The body of the Enviro500 was based on the original style of the single-deck Enviro300, and the upper-deck frontal design was similar to the design used on the Plaxton President body.
The vehicle exceeded some design limitations in Hong Kong, prompting the local Transport Department to make some exclusions in order to make the buses available to KMB on time.
The width of the bus is 2.55 metres exceeding the limit of 2.50 metres. The width of 2.55 metres was approved by the European Union, becoming the current standard.
A fixed glass replaced the emergency door at the rear of the upper deck, but with more hammers available for emergency.
The front indicators are the smallest of all current models of Kowloon Motor Bus.
The facelifted version of Enviro500 body, first built in late 2003, have revised frontal and rear designs. This version of Enviro500 bodywork was also available with Volvo B9TL chassis.
In 2011, Alexander Dennis unveiled the restyled Enviro500 for North American market, which had the same front with the Enviro400. At the same time, a "Go-Anywhere" version of Enviro500 with an overall height of 4.115 m (13 ft 6 in) also became available
