The Toyota 4.7-liter engine, known for its robust performance and reliability, has been a staple in several Toyota models over the years. However, like all good things, the production and use of this engine came to an end. In this article, we will delve into the history of the 4.7 engine, its applications, and most importantly, when Toyota decided to stop using it.
Introduction to the 4.7 Engine
The 4.7-liter engine, also known as the 2UZ-FE, is a V8 engine produced by Toyota. It was first introduced in 1998 and was used in various Toyota models until its discontinuation. This engine was renowned for its smooth operation, powerful performance, and durability. The 4.7 engine was designed to provide a balance between power and fuel efficiency, making it an ideal choice for both on-road and off-road driving.
Applications of the 4.7 Engine
The 4.7-liter engine was used in several Toyota models, including the Sequoia, Tundra, and Land Cruiser. Each of these models required a powerful engine to handle their size and weight, and the 4.7 engine fit the bill perfectly. In the Sequoia, for example, the 4.7 engine provided enough power to tow heavy trailers and navigate challenging terrain. Similarly, in the Tundra, the 4.7 engine offered impressive hauling capabilities and smooth acceleration.
Sequoia and Tundra Engine Specifications
In the Toyota Sequoia, the 4.7 engine produced 235 horsepower and 320 lb-ft of torque. Meanwhile, in the Tundra, the same engine delivered 235 horsepower and 315 lb-ft of torque. These specifications made the 4.7 engine a favorite among truck and SUV enthusiasts, who valued its reliability, durability, and overall performance.
Reasons for Discontinuation
So, why did Toyota decide to stop using the 4.7 engine? There are several reasons that contributed to this decision. Firstly, emissions regulations became increasingly stringent, and the 4.7 engine, although reliable, was not designed to meet these new standards. Secondly, consumer preferences shifted towards more fuel-efficient engines, and the 4.7 engine, despite its impressive performance, was not the most fuel-efficient option available.
Replacement Engines
To replace the 4.7 engine, Toyota introduced newer, more efficient engines that met the latest emissions standards. For example, the 5.7-liter V8 engine was introduced in the Tundra, offering more power and better fuel efficiency than the 4.7 engine. Similarly, the 3.5-liter V6 engine was introduced in the Sequoia, providing improved fuel economy and reduced emissions.
Comparison of Old and New Engines
A comparison of the old 4.7 engine and the new 5.7-liter V8 engine reveals some interesting insights. While the 4.7 engine produced 235 horsepower and 315 lb-ft of torque, the new 5.7-liter engine delivers 381 horsepower and 401 lb-ft of torque. This significant increase in power and torque makes the new engine a more capable and efficient option for truck and SUV enthusiasts.
When Did Toyota Stop Using the 4.7 Engine?
Now, to answer the question that has been on everyone’s mind: when did Toyota stop using the 4.7 engine? The production of the 4.7 engine was phased out in 2009, and it was last used in the 2009 Toyota Sequoia. After this, Toyota began to focus on more fuel-efficient and environmentally friendly engines, such as the 5.7-liter V8 and the 3.5-liter V6.
Legacy of the 4.7 Engine
Although the 4.7 engine is no longer in production, its legacy lives on. Many Toyota enthusiasts still swear by the reliability and performance of the 4.7 engine, and it remains a popular choice among those looking for a used Toyota truck or SUV. Additionally, the 4.7 engine has become a staple in the off-road and towing communities, where its power and durability are highly valued.
