Toyota Harrier Overview

1st Generation Harrier (SXU10, ACU10, MCU10 etc.)

The Toyota Harrier SXU10 is the basic model in the Toyota Harrier range. Originally, It had two models, 3.0-liter V-6 engine and 2.2-liter straight-4 engine. Later, the model developed 2.2-liter straight-4 and 2.4-liter straight-4 engines which had VVT-i, which is an automobile variable valve timing technology.
It has both two types of drivetrain 4x4 and 2WD aiming for city driving, and has a 4AT transmission.
The later engine model provided the maximum power output of 140ps at, 5600rpm.

2nd Generation Harrier (ACU30, MCU30, GSU30 etc.)

The second generation of Toyota Harrier is the most popular in terms of models. In the second generation, there was no model change of engine. However, the newly improved "electronically controlled air suspension", so-called EP-S, has been installed to improve maneuverability. Beside the installation of EP-S, the "Super Intelligent 5-speed Automatic (5 Super ECT)" brought smooth acceleration.
Briefly explaining the difference among ACU, MCU and GSU is that the 2400cc models are ACU, 3000cc models are MCU, 3500cc models are GSU, and hybrids are MHU.

2AZ Engine

2AZ-FE Engine is one of the popular engine models of Toyota cars. This engine is employed for Toyota Alphard and Estima also known as Previa. The Straight-4 piston engine is the characteristic of Toyota AZ engine family, and 2AZ line has a 2.4 liter for displacements.

1MZ Engine

1MZ engine is a short stroke engine with a bore of 87.5 mm, stroke of 83.0 mm and bore stroke ratio of 0.95. Its piston diameter is larger than stroke volume. Though, the displacement and number of cylinders are the same, it is said that the engine is inferior to the long-stroke type in torque characteristics at low rpm and is expected to be difficult to handle. However, the engine can produce more power due to improved filling efficiency and a smaller increase in sliding resistance at high rpm.

Overview for 2nd Generation of Harrier

The second generation of Harrier, from 2003 to 2013, was launched in 2003 as a fully remodeled version of the first generation, and is the most popular line of Toyota Harrier among used car buyers. The reason why old models of Harrier have good reviews is its refined design that exudes a sense of quality, and its spacious space as 5 seaters is the point.
Safety equipment has also been enhanced since the first-generation Toyota Harrier, with the seatbelt warning buzzer and two-mirror auxiliary confirmation device now standard equipment. Furthermore, it was the first time that a pre-crash safety system as automotive equipment was installed as an option. The car navigation system has also been upgraded to an HDD type.
The model 240-G PREMIUM L - P, which was sold in 2011, was also the legendary popular Harrier model in the world.

3rd Generation of Harrier

The third generation of Harrier(SXU, ACU and MCU#1), from 2013 to 2020, debuted in November 2013. Toyota fully remodeled the Harrier for the first time in 10 years after a blank of about a year, and changed the generation to the third generation.
The third generation of Harrier’s petrol model's powertrain and drivetrain consisted of a 3ZR-FAE 2.0L straight-4 engine with continuously variable valve lift (VALVEMATIC) that produces 151 ps/6100 rpm and 193Nm/3800rpm, a CVT, and an electronically controlled coupling system (FF). Dynamic Torque Control 4WD was available.
The appeal of the third generation lies in its ability to provide a crisp, high-level ride while excelling in relaxed cruising. In particular, turbocharged vehicles are given high-performance dampers in the suspension for a more direct driving feel.
