What To Know
- This engine is found in the base L and LE trims and does not feature cylinder deactivation.
- While the V6 engine does not have cylinder deactivation in the traditional sense, it employs a different technology called Variable Valve Timing with intelligence (VVT-i).
- To answer the question directly, no, the Toyota Highlander does not offer cylinder deactivation in the traditional sense.
The Toyota Highlander is a popular SUV known for its reliability, spaciousness, and overall value. But does the Toyota Highlander have cylinder deactivation, a technology that can improve fuel efficiency? This is a question many potential buyers ask, and the answer is not straightforward.
Understanding Cylinder Deactivation
Cylinder deactivation is a technology that allows an engine to shut off specific cylinders when they are not needed, such as during cruising or light acceleration. This reduces fuel consumption and emissions by allowing the engine to run more efficiently.
The Toyota Highlander’s Engine Options
To understand whether the Highlander has cylinder deactivation, we need to examine its engine options. There are two primary engines offered in the Highlander:
- 2.4L Four-Cylinder Engine: This engine is found in the base L and LE trims and does not feature cylinder deactivation.
- 3.5L V6 Engine: This engine is found in the XLE, Limited, and Platinum trims. While the V6 engine does not have cylinder deactivation in the traditional sense, it employs a different technology called Variable Valve Timing with intelligence (VVT-i).
What is VVT-i and How Does it Work?
VVT-i is a technology that varies the timing of the intake valves to optimize engine performance and efficiency. This technology is not the same as cylinder deactivation, but it does contribute to better fuel economy. VVT-i works by adjusting the timing of the intake valves based on engine load and speed. When the engine is under light load, the valves open later, which reduces fuel consumption. When the engine requires more power, the valves open earlier, which improves performance.
Does VVT-i Offer Similar Benefits to Cylinder Deactivation?
While VVT-i does not shut off cylinders entirely, it does offer some of the same benefits as cylinder deactivation. By optimizing valve timing, VVT-i helps the engine run more efficiently, reducing fuel consumption and emissions. However, it’s important to note that VVT-i does not provide the same level of fuel savings as cylinder deactivation.
The Toyota Highlander’s Fuel Efficiency
The Toyota Highlander’s fuel economy is competitive for its class, but it’s not at the top of the pack. The four-cylinder engine achieves an EPA-estimated 25 mpg city, 34 mpg highway, and 28 mpg combined. The V6 engine gets an EPA-estimated 21 mpg city, 29 mpg highway, and 24 mpg combined.
Comparing the Highlander’s Fuel Efficiency to Competitors
When comparing the Highlander’s fuel economy to its competitors, it’s important to consider the engine options available in each vehicle. Some competitors, like the Honda Pilot and the Subaru Ascent, offer engines with cylinder deactivation, which can lead to slightly better fuel efficiency. However, the Highlander’s V6 engine with VVT-i still provides respectable fuel economy for its size and power output.
The Bottom Line: Does the Toyota Highlander Have Cylinder Deactivation?
To answer the question directly, no, the Toyota Highlander does not offer cylinder deactivation in the traditional sense. However, it does feature VVT-i technology, which optimizes engine performance and efficiency, resulting in improved fuel economy. While VVT-i doesn’t shut off cylinders entirely, it does offer similar benefits, particularly during light driving conditions.
Final Thoughts: Choosing the Right Highlander for Your Needs
The Toyota Highlander is a reliable and capable SUV that offers a variety of engine options. While cylinder deactivation is not available, the VVT-i technology in the V6 engine provides decent fuel efficiency. If you prioritize fuel economy, the four-cylinder engine might be a better choice. However, the V6 engine offers more power and performance. Ultimately, the best Highlander for you will depend on your individual needs and priorities.
What People Want to Know
1. What is the difference between cylinder deactivation and VVT-i?
Cylinder deactivation shuts off specific cylinders when they are not needed, while VVT-i optimizes valve timing to improve efficiency. Cylinder deactivation offers greater fuel savings, but VVT-i is a more common technology found in many vehicles.
2. Does the Toyota Highlander Hybrid have cylinder deactivation?
No, the Toyota Highlander Hybrid does not have cylinder deactivation. It uses a combination of a gasoline engine and an electric motor, which contributes to its impressive fuel efficiency.
3. How does VVT-i improve fuel economy?
VVT-i improves fuel economy by adjusting the timing of the intake valves. When the engine is under light load, the valves open later, which reduces fuel consumption.
4. Is the Toyota Highlander a good choice for fuel efficiency?
The Toyota Highlander offers decent fuel efficiency for its size and power output. However, some competitors offer engines with cylinder deactivation, which can lead to slightly better fuel economy.
5. What are the other advantages of the Toyota Highlander?
The Toyota Highlander is known for its reliability, spaciousness, comfortable ride, and safety features. It’s a versatile SUV that can handle a variety of driving conditions.
