The SKY-G engine is a 2.0 liter unit with direct injection and an improved variable valve timing system which gives it a 15% fuel economy and torque advantage over the current MZR engine in the Mazda 3 2.0 Sport. Direct injection was previously found only on the turbocharged 2.3 liter engine but is now available in the ‘regular’ engines.
The Mazda SKY-D engine is a 2.2 liter unit that offers fuel economy of approximately 20% better than the current 2.2 liter diesel engine. It features a newly designed engine block that reduces mechanical friction to the level of a gasoline engine. Other features include piezo injectors and a two-stage turbocharger. It doesn’t sound like its a twin-turbo setup, but instead is probably a variable geometry turbocharger.
