Citroen UK has added Euro 6.2-compliant powertrains to its Relay Ready to Run conversions range.
The powertrains are also available on its Relay chassis cab, chassis crew cab, floor cab and Back to Back offerings.
The new 2.2-litre diesel engine is available with power outputs of 142PS for X variants or 167PS for Plus models. A six-speed manual transmission is standard on both outputs.
Standard equipment on Plus models includes air conditioning, a heavy-duty battery and extended wiring at the rear of the vehicle, while chassis cab and chassis crew cab models also feature heavy-duty reinforced rear suspension.
Plus models, which are powered by the 167PS engine, also include built-in cup holders and smartphone storage in place of the lower central glovebox.
Among the options now available are the Touchscreen Navigation Pack, which incorporates digital radio, a five-inch colour touchscreen, Bluetooth connectivity and a USB socket.
Customers can also choose the Drive Assist Pack, which includes active safety brake, collision alert, lane departure warning, smart beam headlights and speed limit recognition.
Earlier this year, Citroen updated its Relay large panel van with new powertrains.
