Modern drives, clever lightweight construction

I innovations are the gold of automakers. Everyone is constantly working on economical engines, efficient transmissions and lightweight bodies. Mazda has given all of these efforts an overarching name: Skyactiv. There are two differences to the competition. On the one hand, all Mazda models benefit equally from all technical advances. Which is why the brand does not use eco lettering at all. True to the motto: all or nothing.

On the other hand, the Japanese are not shrinking the displacement of their engines and using exhaust gas turbochargers to pump them up, as the competition does under the term downsizing. Strictly speaking, Mazda pursues the opposite: its four-cylinder engines work with comparatively large displacements and extreme compression values, thereby improving their efficiency. The Skyactiv petrol engines have a very high compression ratio: the 2.0 liter four-cylinder achieves the highest compression ratio of a large-scale production petrol engine at 14: 1. Such measures usually result in unpleasant knocking noises - Mazda has avoided these through clever injection, specially shaped pistons and smart exhaust manifolds (similar to motorsport).

The diesel engines work with the world's lowest compression ratio of 14: 1, which means that the fuel can mix better with the air and fewer pollutants are produced. Mazda's diesel engines even meet the Euro 6 emissions standard without complex and expensive storage catalysts. A unique solution that can be found in our Endurance test-CX-5 over 100,000 kilometers worked without problems.

Cold start? You're welcome

Anyone who thinks that Skyactiv diesel with such low compression would have cold start problems in winter is wrong. Thanks to special injection nozzles, this also works perfectly. Incidentally, register turbochargers increase the temperament of diesel engines. In addition to the standard automatic start-stop system, Mazda has another savings ace up its sleeve. It's called i-Eloop and uses braking energy. Can others do too? Right. But Mazda does not pump the energy into the vehicle battery - which makes less use of rapid power surges - but into a capacitor. For example, he feeds the radio and the like at red lights during theMotor takes a break. An important Skyactiv point: reducing the weight of the vehicle. Thanks to the extensive use of high-strength steels in the body, the weight of the models has been reduced by around eight percent, with a simultaneous increase in rigidity of 30 percent and the best crash safety.

Infotainment and active safety

Three letters summarize the world of infotainment at Mazda: MZD. Technology professionals like to put the word 'connectivity system' in front of it. This refers to all the functions that are used for entertainment in the vehicle. Those who order MZD can very easily couple their smartphone to the system via Bluetooth and rely on secure access to the Internet. This maintains contact with all social networks, and emails and text messages can be read out and answered while driving. If you like, you can listen to either Internet radio or digital radio in between.

The MZD is controlled via the central rotary wheel in the center console (Multi Commander), directly on the seven-inch colored touch screen or via voice control. Wer If you choose the navigation system with the optional live services, you can carry out all map updates free of charge for the next three years.

Better safe than sorry

Mazda's active safety program i-Activsense is even more extensive. The most modern systems are used in the flagship 6, but are also available for the other models. They are all intended to alert the driver to dangerous situations and thus prevent accidents.

Here is a brief introduction to the most important assistants:

  • adaptive cruise control (MRCC). It not only maintains the set speed, but also automatically maintains the defined distance from the vehicle in front.
  • Lane Change Assistant (BSM). From a speed of 30 km /h, it uses radar to check the blind spots for other cars and gives a visual and acoustic warning. Scans its own lane via camera. If the Mazda leaves this area unintentionally, it is warned visually and acoustically and automatically counter-steered. The system does not work if the driver takes their hands off the steering wheel.
  • City Emergency Brake Assist (SCBS). An infrared laser is used to determine the distance and speed difference to the vehicle in front between 4 and 30 km /h. If the system detects a risk of collision, it applies the brakes. If these are not activated by the driver, emergency braking is automatically initiated.
  • Adaptive full-LED headlights (ALH). Provide optimal brightness when illuminating the road, including curves, and automatically adapt their light cones to different situations. Need less energy at the same timeas xenon or halogen headlights.
  • High beam assistant (HBC). With the help of the front camera, it detects whether switching on its own high beam does not dazzle other vehicles, performs this independently and also automatically dips the light again.
  • Parking assistance system (RCTA). It uses the radar sensors of the lane change assistant and can therefore warn of crossing vehicles when reversing out of a parking space.

Mazda is also a pioneer when it comes to head-up displays, which are available for almost every model. We are talking about the small window, on which the driver is shown important information such as speed and navigation arrows directly in front of the windshield. As a result, your gaze doesn't wander around, all your concentration can be devoted to the road.
