In July 2019, approximately 262,000 Mazda vehicles using the engine were recalled for a faulty powertrain control module that may cause a misfire or a loss in power. Naturally-aspirated Skyactiv-G 2.5 engines manufactured from 2018 onwards feature cylinder deactivation to improve fuel efficiency. The MX- facelift received an updated engine producing 181 bhp (184 PS 135 kW) with maximum RPM raised from 6800 to 7500 rpm and includes a larger intake manifold, increased injection pressure and a new exhaust system that scavenges the cylinders more quickly. Versus the engine in the 2011 Mazda3 (with an automatic transmission), they improved fuel economy from 10.2 l/100 km (23 mpg ‑US) to 8.4 l/100 km (28 mpg ‑US) in town, and from 7.1 l/100 km (33 mpg ‑US) to 5.8 l/100 km (41 mpg ‑US) on the highway compared to the 2011 model. In some markets, the 162 bhp (164 PS 121 kW) and 210 N⋅m (155 lbf⋅ft) of torque with Flexifuel E85 is available.Īccording to Mazda, it is more fuel efficient than the engine it replaces. version has a compression ratio of 13.0:1 producing 155 bhp (157 PS 116 kW) at 6000 rpm and 200 N⋅m (148 lbf⋅ft) of torque at 4600 rpm. The Skyactiv-G 2.0 or (PE-VPS) was the first engine in the Skyactiv-G family to be produced. 2016–2020 Scion iA/Toyota Yaris (North America).It greatly improves dynamic performance and fuel economy over the MZR 1.5 engine of the previous model. This new petrol engine added to the Skyactiv line-up achieves a high compression ratio of 13.0:1 (14.0:1 in some markets).
This 4 cylinder engine was introduced in the 14MY Mazda3 for the Asian and European markets, it develops 85 kW (114 hp) at 6,000 rpm and 111 lb⋅ft (150 N⋅m) of torque at 4,000 rpm (Asia Markets). The Skyactiv-G 1.5, or (PR-VP RS) for RWD applications and (P5 VPS F-P5) for FWD applications, is a 1,496 cc (91.3 cu in) engine with a 74.5 mm (2.93 in) bore and an 85.8 mm (3.38 in) stroke. The engine was first used in the Mazda2 1.3-Skyactiv. įive Mazda engineers were awarded the 2011 Japan Society of Mechanical Engineers Medal on Apspecifically for the "development of a petrol engine (1.3 L) with a super-high compression ratio and achieving fuel efficiency of 30 km per litre (under Japan's 10-15 cycle)". The engine was unveiled at the 2011 Automotive Engineering Exposition. The Skyactiv-G 1.3 (P3-VPS) is a variant with 1,298 cc (79.2 cu in) engine displacement and features a 71.0 mm (2.80 in) bore and an 82.0 mm (3.23 in) stroke.
market have a lower compression ratio of 13:1 allowing them to operate on standard instead of premium fuel with an approximate 3-5 percent reduction in torque and fuel economy. It features an all-aluminum construction with chain-driven dual overhead camshafts with VVT and gasoline direct injection with direct ignition, it meets ULEV emission standards. In addition, combustion duration is shortened by intensifying air flow, increasing injection pressure, and using multi-hole injectors.
To reduce the risk of engine knock at high compression, residual gas is reduced by using 4-2-1 engine exhaust systems, implementing a piston cavity, and optimizing fuel injection. The engine compression ratio is increased to 14.0:1. The Skyactiv-G is a family of direct injection petrol engines. Mazda's previous chassis for the Mazda 3 and Mazda 6 were carried over to the new vehicles.

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, etc. The precursor of Skyactiv, which featured a Mazda Sky-G 2.3-liter direct injection gas 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.
