Dynamic Force 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 centreline. Other methods include:
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.23 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 had 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.4 On 12 June 2021, the first turbocharged four-cylinder model, named T24A, was introduced for the AZ20 series Lexus NX.56
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.

The T24A engine is a straight-four engine series that was first introduced in 2021 for the AZ20 series Lexus NX.
The "T" in the engine feature suffix "-FTS" designates the turbocharged version of this engine.17 Toyota have been using it to replace the naturally-aspirated 2GR-FKS V6, offering more peak torque at lower speeds and improved fuel consumption and emissions with the turbo engine.18
There also are two distinct hybrid variants which carry the same T24A-FTS engine designation as the regular (non-hybrid) variant. For transverse engine applications (marketed as "Dual Boost Hybrid System" in Japan and "Hybrid MAX" in North America), the hybrid engine drives the front wheels and is equipped with two electric motors: one starter-generator and one traction assist; a third electric motor driving the rear axle is provided with all-wheel drive as a power-split hybrid variant. For longitudinal engine applications (marketed as "i-FORCE MAX" in North America), a single traction assist/generator motor is sandwiched between the engine and transmission, taking the place of a conventional automatic transmission torque converter.19

The V35A engine is a V6 engine series that was first introduced in 2017 for the XF50 series Lexus LS. Despite its "35" nomenclature and being advertised as a 3.5-litre engine, its actual displacement is 3.4 L (3,445 cc).
The twin-turbocharged version with 10.5:1 compression ratio. Pumping losses have been reduced by electrification of the waste gate of the twin turbo system. The engine achieves 37% thermal efficiency.20 A hybrid version (marketed as "i-FORCE MAX" in North America) is also available with the same engine designation as the regular variant.
The hybrid version was named Ward's World's 10 Best Engines list in 2022.21
A number of customers have reported main bearing failures in 2022 and 2023 vehicles equipped with the V35A-FTS engine, with mileage as little as 40,000 km (25,000 miles).22
