Mazda recently pulled the wraps off the 2018 Mazda3 but a new report is indicating the company will use the Frankfurt Motor Show to reveal new engine technology that will debut in the next-generation model.

According to Motoring, the automaker will display its new “homogenous charge compression ignition” in Germany next month.

Details are limited but HCCI technology is a so-called ‘sparkless ignition’ system which uses pressure to ignite a fuel and air mixture. This eliminates the need for traditional sparkplugs and helps to improve efficiency.

Following the introduction of the HCCI system in Frankfurt, Mazda will reportedly introduce a concept which previews the next-generation Mazda3. The concept is slated to be unveiled at the Tokyo Motor Show in October but nothing is official at this point.

If the publication’s sources are correct, the next-generation Mazda3 will be based on the same platform as the current model but come equipped with all-new body work and possibly an upgraded interior. The car is also slated to feature all-new Skyactiv II engines which will make use of the company’s HCCI system.

After their debut on the Mazda3, the Skyactiv II engines will eventually spread to the rest of the company’s lineup.
