The ever-popular Mazda 3 is available as both a four-door sedan or five-door hatchback to fit differing tastes. Completely redesigned last year and built on an all-new platform, the sedan and hatchback have distinctly different rear side profiles and rear styling.

The Hatchback is available in Standard, Preferred, and Premium packages, with the sedan adding a Select package at the lower end. Both variants feature a prominent grille accented by slim LED headlights and daytime running lights. Adaptive headlights are offered on the top Premium package. All models are available with either two-wheel- or four-wheel-drive.

Power is delivered by an efficient 2.5-liter, 186 horsepower SKYACTIV-G2 engine featuring dual overhead valves, variable valve timing, and cylinder deactivation. This four-cylinder engine connects to a SKYACTIV-Drive 6-speed automatic transmission with sport mode. A 6-speed manual is available only on the hatchback with the Premium package. All-wheel-drive models use Mazda's i-ACTIV AWD all-wheel drive system. The model also offers the automaker’s latest-generation G-Vectoring Control Plus system that slightly reduces engine torque to sharpen steering feel.

Mazda's long-awaited SKYACTIV-X spark-controlled compression ignition (SPCCI) engine is now available in Mazda3 models Europe and expected to be offered here later in the model year. This innovative engine combines the best features of spark-ignition (gasoline) and combustion-ignition (diesel) engines without either of their disadvantages, while offering greater horsepower, torque, and fuel efficiency.

All 2020 Mazda trim levels now come standard with i-ACTIVSENSE driver-assist features that were previously standard only on higher trim levels. These include Lane Departure Warning, Lane-Keep Assist, Mazda Radar Cruise Control with Stop & Go, Driver Attention Alert, Blind-spot Monitoring, and Automatic Emergency Braking.

The Mazda3’s driver-focused cockpit includes a 7.0-inch instrument cluster screen and an 8.8-inch infotainment screen with Android Auto and Apple CarPlay. A head-up display is optional. The Mazda3 offers an entry price of $21,500 for the sedan and $23,700 for the hatchback variant.

Internal combustion engines power the vast majority of the cars and trucks on the road today. That’s not by any means a bad thing. While electrification of our cars dominates most of today’s headlines and resources, the internal combustion engine is still what moves most of us from one place to another.

These tried-and-true powerplants have evolved to meet modern requirements in ways that lend flexibility to current and future needs. A primary advantage to internal combustion is that engines can be powered by multiple fuel sources including gasoline, diesel, and an array of alternative fuels. That flexibility provides options moving forward.

Hybrid cars and trucks, in all their configurations, are a gateway to pure electric vehicle acceptance. Gasoline-electric hybrids rely on an efficient internal combustion engine to function. The hybrid envelope has expanded in recent times to include plugin models that can travel varying distances on pure electric power as well.

Automatic start-stop function is an important technology that makes internal combustion vehicles more city-friendly by shutting an engine off when stopped at a traffic light for more than a few seconds, eliminating unnecessary idling emissions. The engine remains off as long as a driver’s foot is on the brake pedal and the vehicle is not in motion. When the light changes, lifting off the brake immediately restarts the engine and you drive away.

Fuel economy improvements, lower carbon emissions, and overall emissions reductions are also being accomplished by other strategies. Among the most prominent is engine downsizing, which allows the use of smaller displacement engines boosted with power-adding technologies like turbocharging. The old adage, ‘there’s no replacement for displacement,’ is being successfully circumvented by smart engine downsizing.

Some elegant solutions are presenting themselves. One example is Nissan’s VC-Turbo, the world’s first variable compression production engine. Modifying engine compression ratio through sophisticated computer control allows adjusting compression in real time, optimizing efficiency and performance depending on driving conditions.

Another example is the introduction of Chevrolet’s next-generation Dynamic Fuel Management in Silverado 5.3-liter and 6.2-liter V-8 engines. This advanced technology optimizes power and fuel efficiency through cylinder deactivation, determining 80 times-per-second how many cylinders are actually needed for real-time driving needs, with the engine running on as little as a single cylinder to save fuel and decrease carbon emissions.

Gasoline engines have traditionally required a spark plug to ignite the fuel-air mixture in an engine’s combustion chamber to drive a piston. More thermally efficient diesel engines create ignition as a piston compresses the fuel-air mixture at high pressure, without a plug. So, what if you could combine the best of both worlds and make a gasoline engine work more like an efficient diesel? 

It now appears the technology is ready for prime time and production. Mazda’s new SKYACTIV-X is set to become the world’s first production engine to use compression ignition in a commercially available gasoline engine. The automaker’s proprietary Spark Controlled Compression Ignition design provides considerable torque during acceleration, along with sharp engine response, improved fuel efficiency, and lower emissions. 

The worldwide push toward electric vehicles has yielded some surprising consequences. One is an all-out effort to make combustion vehicles better and more competitive with the advancement and sharing of technologies across all platforms.

Is the internal combustion engine dead? Hardly. It just keeps getting better, more efficient, and technologically advanced as the years roll by.
