Mazda Sky D and Sky G engines -- Click above for high-res image gallery

The Mazda Sky D diesel and Sky G gasoline engines are meant to bring "everlasting blue sky" to oversee "sustainable Zoom-Zoom." Both utilize low-friction engine blocks, direct injection and piezo-electric injectors. The Sky G is fitted with a "highly functional variable valve timing mechanism," and the Sky D gets a 2-stage turbocharger besides.

Together with technologies such as the Sky Drive 6-speed transmission, i-stop, regenerative braking and lighter vehicles, these lumps will form the core of Mazda's goal of a 30% increase in fuel economy in the coming years. You can read more about them after the jump, and check them out in the gallery of high-res photos below.

PRESS RELEASE

Mazda Global Premiere of Eco-Friendly and Powerful Next Generation 'SKY-G' and 'SKY-D' Engines at Tokyo Motor Show 2009

HIROSHIMA, Japan-Mazda Motor Corporation will showcase the world premiere of its next-generation engine lineup and automatic transmissions at the 41st Tokyo Motor Show, to be held from Saturday, October 24 through Wednesday, November 4, 2009. Mazda will exhibit the 'Mazda SKY-G' direct injection gasoline engine, the 'Mazda SKY-D' clean diesel engine and the 'Mazda SKY Drive' high-efficiency automatic transmission. The Tokyo Motor Show, to be held at Makuhari Messe in Chiba Prefecture, will also mark the Japan debut of the Kiyora concept car as an exhibit of Mazda's next-generation environmental and safety technologies.

Mazda's theme for the 2009 Tokyo Motor Show is "The Mazda SKY concept -- Providing driving pleasure and environmental and safety features for all customers!" Under the headings of "Today," "Tomorrow" and "The Future," Mazda will display advanced technologies designed to improve the average fuel economy of Mazda vehicles sold globally 30 percent by 2015 compared to 2008 levels. This is one of the goals of Mazda's long-term vision for technology development, Sustainable Zoom-Zoom.

Mazda is committed to significantly improving the core aspects of its vehicles that affect performance – engines, transmissions, and lighter vehicle weight – in order to achieve elevated driving pleasure together with outstanding environmental and safety features. The Mazda SKY concept defines Mazda's approach to developing next-generation powertrains that will significantly improve the eco-friendliness and dynamic performance of all Mazda vehicles. The SKY concept embodies Mazda's desire to ensure an "everlasting blue sky" under which drivers will always be able to enjoy the fun-to-drive pleasure afforded by owning a Mazda. The concept also reflects the "sky's the limit" aspirations of Mazda's engineers as they employ unconventional thinking to achieve optimal performance in every vehicle that bears the Mazda nameplate.

Based on the SKY concept, Mazda's "Technologies for Tomorrow" display at this year's Tokyo Motor Show will include the next-generation direct injection gasoline Mazda SKY-G engine and the Mazda SKY-D clean diesel engine. Both offer improved eco-friendliness and torque thanks to optimized combustion efficiency. Mazda will also reveal the first next-generation automatic transmission, the Mazda SKY-Drive, which offers first-rate fuel economy and a direct driving performance feel.

      Relatively speaking, Mazdas have been guzzlers up to now, so this is perhaps more a catch-up move than a case of breaking new ground.

        They haven't. You just need to know how to drive them. And I'm not talking hypermilling, I'm talking being dynamic. You can drive a 2.5 liter MZR with the VW 1.9 TDI fuel economy + 10%. And you can drive current Mazda 2.2 MZR-CD with better economy than comparable VW diesels while enjoying higher torque.

        I call bull$hit. You can't get VW 1.9 TDI fuel economy + 10% from the 2.5 L MZR even if you're driving down hill with the wind in a straight line. And certainly not in the dynamic way a Mazda is meant to be driven.

      A turbo diesel Mazda 3 hatch would sell like hotcakes!

      Way to go Mazda.
      I love their cars, my Protege is the best small car I've ever driven.
      The only thing which bugs me is that they don't get great fuel efficiency.
      If they nail that, without altering all of the 'zoom-zoom', my next car will probably be another Mazda.

      I'd love to see a diesel option for the Mazda 3. But I think a lot of companies are still taking a "wait and see" approach.

      Awesome give me the gas version with 6 speed manual in the Mazda 3 hatch (and make it stop grinning like an idiot) and we have sale.

      If you haven't been looking, there are a few chevrolet gas engines out there with direct injection. More automakers are working on DI engines for the US market thankfully.

      The DI 2.0 from mazda should be killer. I really doubt we'll get the diesel though.

      These guys are incredible. They help bail out the US economy with their product innovation and still deliver technology like this.
      • 5 Years Ago
      Great, but when will they be in U.S. products? Maybe I should delay my miata purchase...
      • 5 Years Ago
      Is Mazda working on hybrid tech? I wasn't aware of it... The post mentions regenerative braking, but the press release doesn't.

      A hybrid wouldn't interest me (without a lot of convincing), but a US-spec turbocharged Mazda(speed)2 with the Sky D would. Or something along those lines.
