The 1.5-liter Mazda P5-VPS or SkyActiv-G 1.5 gasoline engine has been produced at the plant in Japan since 2013 and is installed on the company’s most compact models under the indexes 2 or Demio and 3 or Axela. There is a modification of this motor with the P5-VP index for the rear-wheel drive model MX-5.
The Mazda SkyActiv 1.5 engine is a relatively new engine from the Skyactive series, which replaced the MZR in general, and the 1.5 liter, in particular, replaces the outdated 1.6 Z6. SkyActiv 1.5L is presented in two versions, with a compression ratio of 13 and a power of 100 hp and with a compression ratio of 14 and a power of 120 hp. In both versions, the engine has direct fuel injection and a variable valve timing system on the intake and outlet shafts Dual S-VT. This is an engine with a lightweight connecting rod and piston group, pistons with a special shape for maximum optimization of the combustion process and reducing the possibility of detonation.
The Skyactiv-G family also includes engines: PE‑VPS and PY‑VPS.
The engine was installed on:
- Mazda 2 DJ since 2014;
- Mazda 3 BM in 2013 – 2019;
- Mazda 3 BP since 2018.
