Mazda hard at work on Skyactiv 2 engine technology

As Mazda continues the current rollout of its still-new Skyactiv technology, the automaker is already looking at improving its family of engines for even better fuel economy and emissions reductions. Automotive News reports that with stricter fuel economy and emissions regulations planned for 2020 and 2025 in Europe, Mazda will likely release engines with next-generation Skyactiv 2 technology by the end of this decade, and Skyactiv 3 units just five years later.
The latter is expected to focus on improved engine cooling and lessening energy losses, but the big news in AN's report is that the next-gen Skyactiv 2 engines will use Homogeneous Charge Compression Ignition, or HCCI. This type of ignition is very similar to how a diesel engine operates (with high compression and using the compression stroke for fuel combustion rather than spark plugs), a method said to provide a cleaner and more efficient fuel burn - to the tune of a 30-percent improvement in fuel economy compared to current Skyactiv engines. Other automakers, including Hyundai, have already announced they are developing HCCI powerplants with similar technology and characteristics, so Mazda likely won't be a lone wolf here.
Equipped with HCCI technology, Mazda figures to be able to compete with larger automakers in terms of fuel economy and emissions without resorting to hybrid powertrains, continuously variable transmissions or automatics relying on more forward gears (eight or more) for optimal efficiency. Some of the challenges of HCCI, according to AN, include the need for better engine cooling, risk of misfire at high and low rpm and uneven engine performance based on fuel properties.

Evo blasts around in a Spa 24H-winning Mazda RX-7

Think of the Mazda RX-7 today, and your thoughts likely turn to the turbocharged third-generation version of the '90s that's an icon among the tuning and drifting communities. Many years before that swoopy coupe was hanging the tail out, the first model of RX-7 was also quite a track star, though. Evo's Richard Meaden has gotten ahold of a race-prepped version that counts a victory in the 1981 Spa 24 Hours to its name – the first Japanese car to claim that honor – for a fantastic video. With 225 horsepower and weighing around 1,984 pounds, this RX-7 doesn't look like a giant killer on paper. However as Meaden illustrates, the coupe puts those rotary-powered ponies to very good use. Driving it requires constantly keeping things on the boil because the muscle is essentially absent below 7,000 rpm. Once in the sweet spot, things start progressing quickly, though. As a wonderful cap to the wall of noise from the engine, little licks of flame also shoot out of the exhaust on downshifts. Thankfully, Evo's video team captures all of the mechanical noises quite well, and the clip is a treat for those with a good pair of headphones. Despite the race-winning pedigree, Meaden has no problem grabbing the little coupe by the scruff of the neck. He chucks it through the corners to get the tail loose, and the little wisps of smoke from the rear tires prove the original RX-7 knows how to drift too. These early cars definitely worth being remembered in the pantheon of Mazda performance.

Mazda starts production of new MX-5 Miata in Japan

We often regard a new model as having arrived when its manufacturer reveals it for the first time. But you might argue that nothing is official until actual production gets underway. And that's just what's happened now with the new Mazda MX-5. The fourth-generation Miata was unveiled a few months ago, and now the first examples have begun to roll off the assembly line at Mazda's Ujina plant in Hiroshima. The first ones are set to stay in Japan, where the new roadster is being introduced initially. Deliveries are set to launch in June. After that, we can expect the new MX-5 to proliferate to markets around the world, including our own. To date Mazda has sold more than 950,000 of its little roadsters, making it the best-selling two-seat sports car in the world. It shouldn't be long, then, before the new model tips it past the million-unit mark. 2015/03/05 Mazda Starts Production of All-new Mazda MX-5 HIROSHIMA, Japan-Mazda Motor Corporation today began production of the all-new Mazda MX-5 two-seater lightweight sports car (known as Mazda Roadster in Japan) at Ujina Plant No.1 in Hiroshima. The first models produced are destined for the Japanese market. Sales of the all-new MX-5 will begin in Japan around June this year and interested buyers can make an appointment for pre-sale discussions through a dedicated website from noon on Friday, March 20. Following sales start in Japan, the MX-5 will be progressively rolled out to overseas markets. The MX-5 is an iconic model representing Mazda's vehicle engineering philosophy: the pursuit of driving pleasure. With production exceeding 950,000 units as of the end of January 2015, the MX-5 continues to hold the Guinness World Record for the world's best-selling two-seater sports car. In order to respond to ever increasing demands for safety features and environmental performance while maintaining the element of fun that has always defined the model, development of the fourth generation MX-5 was carried out under the motto "innovate in order to preserve". In addition to incorporating SKYACTIV TECHNOLOGY and KODO-Soul of Motion design, development focused on enhancing the senses and sensations through which people enjoy cars. Moving forward, Mazda will continue to enrich the lives of its customers through a variety of touch points including the production of high-quality vehicles, and become a brand that maintains a special bond with its customers.
