Alfa Romeo has updated the entire petrol and diesel engine lineup for the Giulietta hatchback in the UK, lowering emissions and improving fuel economy in the process.

Changes are most obvious on the 1.6 JTDM-2 engine, which now benefits from more power as well, as output has increased from 105hp to 120hp. Thanks to the addition of a variable-geometry turbo charger and low rolling-resistance tyres, CO2 emissions are down from 104g/km to 99g/km, while fuel efficiency improves to 74.3 mpg (3.8 l/100 km) on the official combined fuel economy cycle. That’s a significant improvement over the 70.6 mpg (4 l/100 km) recorded by the current 105hp engine.

The drop in emissions results in a one percent BIK (benefit-in-kind) reduction to 17 percent. Furthermore, the annual Road Fund Licence is now £0. Thanks to the additional power, the engine boosts top speed by 6 mph (10 km/h) to 121 mph (195 km/h), while the 0-62 mph sprint is improved by 1.3 seconds to 10.0 seconds.

All other engines available for the Giulietta in the UK see their emissions and economy improved, with the exception of the recently-introduced 2.0 JTDM-2 turbo diesel with 150hp.

Despite the updates, pricing remains unchanged, with the 1.4 TB 120hp Progression starting at £18,450 OTR and the 1.6 JTDM-2 120hp Progression priced from £19,500 OTR.

The high-spec Business Edition model starts from £19,080 OTR for the 1.6 JTDM-2 120hp turbo diesel. The model features a 6.5-inch touchscreen Uconnect infotainment system with voice activated satellite navigation, 3D mapping and DAB digital radio, front and rear parking sensors, automatic lights and wipers, alloy wheels and metallic paint.
