Mazda CX-3: range updates bring larger diesel engine

  • Diesel engine grows from 1.5-litres to 1.8-litres
  • Available on Sport Nav+ only, CO2 emissions of 114g/km
  • On sale from 31 August, with updates for the rest of the range

The Mazda CX-3 gains a new, larger-capacity 1.8-litre diesel engine and is available to order from 31 August. The rest of the CX-3 range receives a raft of changes as part of its 2018 update too - further details of which can be found below.

Badged SkyActiv-D, this engine is available in two-wheel drive form only, in flagship Sport Nav+ trim level with a P11D value of £22,635.

What’s new about this engine?

The 1.8-litre engine offers more power with 114hp – up from the 105hp offered on the outgoing 1.5-litre. Torque remains the same at 270Nm, but CO2 output rises from 105g/km to 114g/km. Top speed is 114mph and 0-62mph takes 9.9 seconds.

The claimed fuel economy figure drops down from 70.6mpg to 64.2mpg, but it’s worth noting this figure was achieved under the more stringent WLTP system and should be more achievable during ownership.

Stop-start is standard but, unlike before, there is no four-wheel drive version or automatic gearbox available with this diesel engine.

How much does the Mazda CX-3 cost to tax?



BIK rate (%)

Monthly BIK cost (20%)


1.8-litre SkyActiv-D Sport Nav+





2.0-litre SkyActiv-G SE Nav+ 121PS 2WD auto

With only one trim level available, the CX-3 diesel will cost just under £102 in BIK for a 20% taxpayer. Those who don't cover a high amount of mileage may be tempted by the 121hp 2.0-litre petrol engine for just under £104 per month, and for those seeking an automatic gearbox for a similar cost, you can have one with the petrol 2.0-litre in lower-spec SE Nav+ for just over £102 per month. 

Updates to the Mazda CX-3 range in 2018

Styling changes to the exterior are minor, with a tweaked front grille and a new alloy wheel design for the Sport Nav+.

The interior will be easier to distinguish over the outgoing models, with a revised centre console housing an electronic parking brake and a padded storage box.

The front seats cushions have been revised to provide more comfort and the outer passengers in the rear benefit from a central armrest. To improve refinement, there’s thicker sound isolation in the doors, a thicker headliner and upgraded rear window glazing.

Changes to the suspension and steering have been made to improve how it drives, but the line-up of petrol engines remain the same; offering a 2.0-litre producing either 121hp or 150hp.

The number of trim levels have been simplified down to three: SE Nav+, SE L Nav+ and Sport Nav+.

There will be a special edition Sport Black+ from 1 October but will be limited to just 500 cars, featuring 18-inch silver alloy wheels, front parking sensors, black rear spoiler and door mirrors as standard. Inside there's a head-up display, rear-view camera, a black leather interior and heated steering wheel. The 121hp 2.0-litre petrol is the sole engine available and comes with either a manual or automatic gearbox.
