Euro 6d-Temp diesel engines have been added to Alfa Romeo's Giulia and Stelvio ranges as part of a mid-term model refresh.

This means the diesel models now use the AdBlue additive, which the manufacturer says provides a reduction in NOx emissions as well as seeing a power gain of 10PS

In the Giulia, both the 160PS and 190PS models offer official combined fuel economy of 57.7mpg and CO2 emissions of 129g/km (NEDC correlated). The changes for the 2019 model year also include increased standard specification and the introduction of a Giulia Veloce Ti model.

The Stelvio now offers CO2 emissions from 139g/km with a 190PS diesel engine or 149g/km with a 210PS engine.

All versions of the Giulia and Stelvio now come with the 8.8-inch Alfa Connect with navigation and Apple CarPlay and Android Auto as standard.

In addition, the Giulia Speciale adds an 18-inch dual five-spoke diamond cut alloy wheel, rear privacy glass, aluminium kick-plates and black brake calipers to its standard equipment list, while Veloce models see new 18-inch five-hole dark finish alloy wheels, rear privacy glass and Convenience pack with keyless entry, external door handle lights and driver’s side dashboard storage as standard.

Standard equipment on the Stelvio range has also been improved with the Super trim level now including Michelin CrossClimate tyres, while the Speciale also adds trear privacy glass, aluminium kick plates and black brake calipers.

The Giulia Veloce Ti joins the Giulia line-up, priced from £45,500 OTR. Building on the Veloce, the Ti adds Quadrifoglio leather and Alcantara heated sports seats with eight-way adjustment, Carbon interior trim with leather dashboard, ambient lighting, black headlining, illuminated Carbon door sills and climate pack to enhance the sporting ambiance of the interior.

Externally it adds 19-inch dark five-hole Quadrifoglio alloy wheels, Carbon V-grille and mirror caps, lighting pack and red brake calipers.
