The Dynamic Force engines are a family of petrol engine series developed by Toyota under the brand's New Global Architecture (TNGA) strategy. The engines were developed alongside the TNGA family of vehicle platforms, as part of a company-wide effort to simplify the vehicles being produced by Toyota.

The engine is used in various Toyota and Lexus models starting with the four-cylinder A25A type installed in XV70 series Camry in June 2017.

Overview

The engine was developed as an engine that is claimed to achieve both driving performance and environmental performance while pursuing high efficiency and low fuel consumption as well as having a "direct feeling, smooth and pleasant acceleration performance".

Specifically, the cylinder head and intake port design improves the tumble flow (longitudinal vortex) to increase the air intake volume–the majority of intake flow is across that portion of the valve closest to cylinder centerline. Other methods include:

  • Expansion of the valve clamping angle. The angle between intake and exhaust valve centerline is 41 degrees–the previous design was 31 degrees.
  • Hydraulically variable valve timing on both intake and exhaust camshafts.
  • Very high compression moderated Atkinson cycle engine.
  • Longer bore and stroke ratio (under-square design).
  • Change of port end shape and expansion of seat inner diameter.
  • Application of updated D-4S (multi-hole injector) system to achieve "high-speed combustion", resulting in thermal efficiency over 40%.
  • Cylinder centerline is offset from crankshaft centerline, meaning that piston top dead center is always equivalent to several degrees of crankshaft rotation.

In development and production of the engine, Toyota claims it would be a "completely new engine design based on the TNGA strategy".

Previously, Toyota offered about 800 engine variants, most of which would be replaced with a much simpler lineup of 17 versions of nine Dynamic Force engines.[1][2] Toyota is also simplifying its lineup of transmissions, hybrid systems, and all-wheel drive systems.

Starting with the four-cylinder A25A type installed in XV70 series Camry in June 2017, the V6 V35A and four-cylinder M20A types have also appeared. On 16 October 2019, the three-cylinder M15A type, which would be installed in the XP210 series Yaris (specifically designed for Japan, Europe, Australia, and New Zealand), was officially announced.[3] On 12 June 2021, the first turbocharged four-cylinder model, named T24A, was introduced.[4][5]

The Dynamic Force engines introduced an updated nomenclature system for Toyota engines and no longer employ the traditional iteration or generation of the engine followed by the one letter or two letter designation for the engine family (such as 5M-GE or 4GR-FE being from the M and GR engine families respectively) and instead incorporate the engine's displacement in between a two letter code such as the M20A, with the "20" denoting a 2.0-litre engine.

Common key technologies
