Mazda CX-3 (2015-2021) Pros and Cons

Pros	Cons
Attractive looks	Not as roomy in the back or boot as some rivals
Reasonably strong engines	Doesn't drive with the verve you'd expect of a Mazda
Well equipped as standard	A Skoda Kamiq has a more comfortable ride

Quick Summary

The Mazda CX-3 (2015-2021) is a stylish compact SUV that combines attractive exterior design with practical everyday usability. Launched during the small crossover SUV boom, it competes in a crowded segment alongside popular rivals such as the Renault Captur, Nissan Juke, and Seat Arona. The CX-3 features a sleek exterior and comes well equipped as standard with features including cruise control, air-conditioning, Bluetooth, and hill-hold assist across the range. However, the cabin lacks the premium feel of some competitors, with cheaper plastics evident throughout.

The CX-3 offers three capable engines: a 1.8-litre SkyActiv-D diesel delivering around 55mpg in real-world driving, and two 2.0-litre SkyActiv-G petrol units achieving 40-46mpg depending on specification. Whilst Mazda's reputation suggests a sporty drive, the CX-3 disappoints slightly with less engaging handling than expected, noticeable body roll, and a firm ride that struggles with bumps and potholes. Rear passenger space is cramped compared to rivals, and the 350-litre boot, whilst expandable to 1,260 litres with seats folded, lags behind competitors. Insurance premiums are affordable (groups 13-18), and servicing is straightforward with fixed-price plans available.

Best for: Buyers seeking an attractively styled compact SUV with strong engines and good standard equipment, and those prioritising affordability and low running costs.

Not ideal for: Those needing maximum rear passenger space or boot capacity, drivers expecting engaging Mazda-like handling, or buyers wanting a particularly comfortable ride quality.


Comparison vs Key Rivals



The Verdict

You should buy the CX-3 if: You're seeking an attractively styled compact SUV with strong engines and good standard equipment, and prioritise affordability and low running costs.

Consider alternatives if: You need maximum rear passenger space or boot capacity, expect engaging handling, or require a particularly comfortable ride quality.

Competitive Position: The Mazda CX-3 (2015-2021) is a solid contender in the compact SUV segment, offering attractive styling and strong standard equipment at a competitive price. Whilst it delivers capable engines and reasonable fuel economy, it falls short of rivals like the Seat Arona in ride comfort and lacks the spaciousness of the Renault Captur. The CX-3 represents good value for budget-conscious buyers who prioritise style and equipment over maximum practicality and driving engagement. For those seeking a more comfortable ride or greater interior space, alternatives such as the Skoda Kamiq or Seat Arona may prove more suitable.
