The Fiat Professional Ducato is now available with a range of Euro 6 engines, employing a low pressure exhaust gas recirculation system (LPEGR) to lower NOx emissions without using emission additives.

LPEGR functions by channelling exhaust gasses away after the DPF, cooling them through a low-pressure EGR cooler and then recirculating them in advance of the turbocharger.

The Ducato also benefits from the addition of a new 2.0-litre 115hp MultiJet II LPEGR engine to replace the current Euro 5 2.3-litre MultiJet 110hp.

Offering up to 47.9mpg on the official combined cycle and CO2 emissions of 157g/km, this entry-level engine represents a significant downsizing compared to the engine it replaces.

The top-of-the-range 3.0-litre 180hp has also been replaced by a new 180hp 2.3-litre MultiJet II Power LPEGR, resulting in improvements in fuel efficiency and emissions (46.3mpg on the official combined cycle and 160g/km), while the core 2.3-litre MultiJet 130hp and 150hp engines also adopt Fiat Professional’s LPEGR technology.

Selective catalyst reduction (SCR) is currently offered on people carrier versions and uses AdBlue fluid to convert nitrogen oxides (NOx) to non-harmful gases.

The fourth-generation Fiat Professional Doblò now offers a full range of Euro 6 compliant engines - including second-generation turbodiesel engines: a 1.3-litre MultiJet II 95hp and a 1.6-litre MultiJet II 105hp, both of which are available in new EcoJet versions to offer an improvement in fuel efficiency (12% and 15% respectively) and emissions levels thanks to the use of Start&Stop; low rolling-resistance tyres; low-viscosity oil; an 'intelligent' alternator; a variable-displacement oil pump and a new aerodynamic pack.

It achieves fuel economy of up to 61.4mpg and CO2 emissions of 120g/km.

Replacing the current 2.0-litre engine at the top of the range, a new 1.6-litre MultiJet II 120hp is now the flagship engine of the Doblò line up, offering similar performance to the engine it replaces but capable of 55.4mpg (official combined cycle fuel economy figure) and CO2 emissions of 135g/km.

The Ducato Euro 6 is available to order now priced from £21,445 while the Doblò EU6 is priced from £13,545* (*prices exclude VAT and OTR charges).
