Mazda has updated the CX-3 compact SUV with new technology and engine upgrades to bring emissions in line with the latest Euro 6d requirements.

2018 Mazda CX-3

Revealed at the New York International Auto Show this week, the 2018 CX-3 follows Mazda’s tradition for subtle mid-life improvements; it’s marked out by a refreshed grille, new paint options and wheels, while the interior features a central armrest.

Matrix LED headlights and traffic jam assist, which maintains lane position and speed relative to other vehicles, are also new, and the CX-3 includes an electronic handbrake with auto hold for the first time. Both of the engines have also been updated, to meet Euro 6d requirements and the first stage of the Real Driving Emissions testing, which came into force last September.

The diesel engine gets a 2bhp power increase as a result of measures to reduce combustion temperatures and cut NOx emissions, and it features a lean NOx trap in the exhaust, but no selective catalytic reduction (e.g. AdBlue) as in some rivals. Meanwhile, the 2.0-litre petrol engine, fitted to most UK cars, emits fewer particulates than its predecessor, but doesn’t require a particulate filter.

Mazda has yet to confirm fuel economy or CO2 emissions for the updated CX-3.
