Mazda 3 BM/BN/BY (2013–2019): How to Remove the Bumpers

Compact yet charismatic - this is how you can describe the third-generation Mazda 3 produced between 2013 and 2019. This model marked an important milestone for Mazda: it debuted the KODO: Soul of Motion design and Skyactiv technology that delivered excellent dynamics and efficiency. Let's see what made it memorable.

Production Years and Model Codes

The third-generation Mazda 3 (known by codes BM for sedans, BN for hatchbacks, and BY for the 2016-2019 facelift) was launched in June 2013 as a replacement for the Mazda 3 BL. It received a facelift in 2016 and was replaced by the fourth generation (BP) in 2019.

 

Body Types and Versions

As before, the Mazda 3 was offered in two body styles:

  • Sedan (BM/BY) - classic three-box design with spacious trunk (408 liters)

  • Hatchback (BN/BY) - more sporty, with shorter rear end and dynamic silhouette

The hatchback was more popular in Europe and Russia, while the sedan was preferred in the U.S. and Asia.

 

2016 Facelift

The updated model (code BY) received:

  • New radiator grille (like the CX-5)

  • LED headlights and daytime running lights

  • Redesigned dashboard (digital in some versions)

  • Improved sound insulation

  • Updated multimedia system (MZD Connect with Apple CarPlay and Android Auto, only in later versions)

 

Engines and Transmissions

The Mazda 3 BM/BN/BY featured Skyactiv engines that combined power and efficiency:

  • Gasoline:

    • 1.5 (100-120 HP) - base engine, ideal for city driving

    • 2.0 (120-165 HP) - most popular version, well-balanced

    • 2.5 (184-194 HP) - mainly for U.S. and Australian markets

  • Diesel (Europe):

    • 2.2 (150 HP) - powerful and economical, but demanding on fuel quality

 

Transmissions:

  • 6-speed manual - precise and "sporty"

  • 6-speed automatic - smooth with quick shifts

Front-wheel drive only (unlike previous generations, all-wheel drive wasn't offered).
