  • 2.0L inline-4 engine capable of up to 155 hp and 150 lb-ft of torque.
  • Choice of six-speed manual or six-speed automatic transmission.

However, there’s a small difference in terms of efficiency:

  • 2018 Mazda3 4-Door: Up to 28 mpg in the city and 38 mpg on the highway
  • 2018 Mazda3 5-Door: Up to 27 mpg in the city and 37 mpg on the highway

Interior Features and Space

Both the 2018 Mazda3 4-Door and the 2018 Mazda3 5-Door provide a rich array of top-spec tech as standard, including a 7-inch full-color touch screen display with:

  • 6-Speaker Sound System
  • Bluetooth Hands-Free Phone and Audio Streaming
  • MAZDA CONNECT™ Infotainment System

However, the 2018 Mazda3 4-Door reserves a few standard features as its own, including an electrochromic mirror.

But the most fundamental difference between interiors is the added cargo space of the hatchback:

  • Up to 12.4 cubic feet in the 2018 Mazda3 4-Door Sedan
  • Up to 20.2 cubic feet in the 2018 Mazda3 5-Door Hatchback

Peace of mind shouldn’t be a concern in either configuration of the 2018 Mazda3. Both earned a 5-Star Overall Safety Rating after exhaustive NHTSA crash-testing, and each is fitted with plenty of safety features as standard.

That said, the 2018 Mazda3 4-Door makes advanced driver-assistance features available in standard models that aren’t available in entry-level 2018 Mazda3 5-Door models, including:

  • Blind Spot Monitoring (BSM)
  • Rear Cross Traffic Alert (RCTA)
