About this engine family

Skyactiv is a brand name for a series of automobile technologies developed by Mazda to increase fuel efficiency and engine output. The initial announcement of the Skyactiv technologies included new engines, but has grown to include transmissions, as well as complete vehicle platforms, which have appeared in Mazda vehicles from 2011 onwards.

In detail

The precursor of Skyactiv, which featured a Mazda Sky-G 2.3-liter gasoline direct injection engine, a Mazda Sky-D 2.2-liter diesel engine, a Sky-Drive automatic transmission, a Mazda Kiyora with Sky-G 1.3 engine and Sky-Drive automatic transmission, was unveiled at the 40th Tokyo Motor Show in 2008. The Skyactiv concept features a revised suspension geometry, improved automatic and manual transmission, and various improvements to Mazda's L- engine such as direct injection, upgraded exhaust manifold, increased compression ratio for cleaner burn and higher thermal efficiency, among other improvements.

Mazda's previous chassis for the Mazda3 and Mazda6 were carried over to the new vehicles. The Skyactiv-G is a family of gasoline engines (the "G" suffix indicates gasoline) featuring gasoline direct injection and high compression ratios. Engines in the family have a compression ratio of up to 14:1, except in the United States where it is 13:1 to allow the use of regular gasoline; the lower compression reduces torque and fuel economy by 3 to 5 percent.

To suppress engine knock at high compression, residual gas is reduced using a 4-2-1 exhaust system, optimized piston cavities, and fuel injection control. Combustion duration is shortened by increasing airflow, raising injection pressure, and using multi-hole injectors. Skyactiv-G engines use all-aluminum construction with chain-driven dual overhead camshafts, variable valve timing, and meet U.S. ULEV emission standards.

The Skyactiv-G 1.3 (engine code P3-VPS) is a naturally aspirated, inline-four engine with a bore and a stroke. It was unveiled at the 2011 Automotive Engineering Exposition. Five Mazda engineers were awarded the 2011 Japan Society of Mechanical Engineers Medal on 20 April 2012 for their work on this engine. It was first used in the Mazda Demio/Mazda2, the only Skyactiv engine paired with a CVT. The engine produces of power and of torque.

Applications: 2011–present Mazda2/Mazda Demio The Skyactiv-G 1.5 (engine codes P5-VP (RS) for RWD and P5 VPS F-P5 for FWD) is a naturally aspirated inline-four with a bore and stroke. Introduced in the 2014 Mazda3 for Asian and European markets, it produces of power at 6,000 rpm and of torque at 4,000 rpm. The engine significantly improved performance and fuel economy compared with the previous MZR 1.5 engine. Applications: 2014–present Mazda Axela/Mazda3 2014–present Mazda Demio/Mazda2 2016–present Mazda Roadster/MX-5 2016–present Mazda2/Mazda Demio/Scion iA/Toyota Yaris iA/Toyota Yaris 2020–present Mazda CX-3 The Skyactiv-G 2.0 (engine code PE-VPS) is a naturally aspirated inline-four engine.

It has an bore and a stroke. In the United States, the engine has a 13:1 compression ratio that produces of power at 6,000 rpm and of torque at 4,600 rpm. A flexible-fuel variant increases output to and when running on E85 fuel. Compared with the previous engine in the 2011 Mazda3 (with an automatic transmission), fuel economy improved from in city driving, and from on the highway. Applications: 2012–present Mazda Axela/Mazda3 2013–2025 Mazda Atenza/Mazda6 2013–present Mazda CX-5 2013–2018 Mazda Biante 2013–2015 Mazda Premacy/Mazda5 2015–present Mazda CX-3 2016–present Mazda Roadster/MX-5 2016–2024 Mazda CX-4 (China) 2019–present Mazda CX-30 2023–present Mazda CX-50 (China) 2024–present Mazda2/Mazda Demio The Skyactiv-G 2.5 (engine code PY-VPS) is a naturally aspirated inline-four engine introduced in the 2013 Mazda 6.

It has an bore and a stroke. In the United States, the 13:1 compression version produces of power at 6,000 rpm and of torque at 4,000 rpm. Output was raised to in 2023, with torque unchanged. Since 2018, the engine has also featured cylinder deactivation for improved fuel economy. The engine is also used on Mazda's plug-in hybrid (PHEV) models, where it is marketed as the e-Skyactiv PHEV, and paired with an electric motor mounted between the engine and transmission.
