The brand-new Tundra hybrid model, the Toyota i-FORCE MAX, upgrades the Tundra’s twin-turbo 3.5L V6. The i-FORCE MAX’s inline hybrid powertrain allows it to produce astonishingly more power and torque than its gasoline-powered counterpart: 437 horsepower and 583 pound-feet of torque.

What does the Toyota truck’s iFORCE sign mean?
The new i-FORCE MAX hybrid system from Tundra is designed for the needs of a full-sized vehicle. By cleverly combining a motor generator system inside the bell-housing with the primary twin-turbo 3.5-liter V6, an inline hybrid powertrain with 437 horsepower and an astounding 583 lb. -ft. of torque is created.
The Toyota iFORCE V8: What is it?
The 5.7 “i-Force” V8, also referred to as the 3UR-FE, is a member of the same global family of Toyota and Lexus V8 engines, along with the 4.6L and 5.0L V8s found in the GX460 SUV and several Lexus cars.
However, the 5.7 liter was created especially for the US market and was also put together there. For the 2007 model year, it made its debut in the brand-new second-generation Tundra truck.
second generation The Toyota Tundra was a larger vehicle than its predecessor, and to compete with Nissan’s Titan and other domestic half-ton trucks, Toyota created a new V8 engine with the same displacement as the storied Chevy 350ci small block.
What does the term “iFORCE” mean?
“The strong V8 engine in the Toyota Tundra is known as i-FORCE. This engine makes use of the VVT-i acronym, means “Intelligent variable valve timing for better fuel efficiency.
The iFORCE engine is made by who?
This innovative design uses an aluminum block with a 3,445 cc displacement with an 85.5 mm bore and 100 mm stroke. The chain-driven, 24-valve Dual Overhead Cam V6 has Dual VVT-i systems. Heat is a constant issue when working with turbos. Because the water-cooled intercooler keeps the turbo temperatures low, Toyota has addressed issue. Modern cylinder heads for maximum boost reliability have been created by Toyota experts. They include a two-layer water jacket structure for maximum coolant flow and combustion chamber strength. Then, machined cross-channels were included to provide additional combustion chamber cooling. To enable increased coolant flow near the spark plug, the intake ports feature low-profile, laser-applied powder metal. To reduce the temperature of the exhaust gas entering the turbochargers, the engine uses a computer-optimized exhaust valve form, an integrated exhaust manifold, and cylinder heads.
According to claims, the redesigned cylinder heads (with cross-channels) increase cylinder head dependability and operational efficiency.
Is the 5.7-liter iFORCE a Hemi?
The Dodge HEMI engine is being used today. The long history of the HEMI engine began in the 1940s when Chrysler modified an experimental V16 fighter aviation engine to produce 2,500 horsepower by adding hemispherical combustion chambers. In an effort to achieve a better fuel-air mixture, engineers discovered that the unconventional cylinder head’s walls maintained a more constant temperature and had space for larger valves, which increased airflow.
The HEMI V8 made its debut in 1951 in cars made by Chrysler. The new engine was used by drag racers throughout the 1950s, and championship drag racers today base their engines on the original HEMI. Dodge introduced the 426, which rules NASCAR, to usher in the second generation of the HEMI. The third-generation HEMI, a contemporary aluminum, fuel-injected V8, was then unveiled by Dodge in 2003.
The Dodge HEMI is still produced today in naturally aspirated 5.7-liter and 6.5-liter versions, as well as an SRT-built 6.2-liter supercharged HEMI. Although Stellantis provides a variety of engines for the Ram, many customers choose the 5.7-liter HEMI, one of the top V8 truck engines.
Dodge engineers modified the 5.7-liter HEMI for the 2009 model year with Variable Camshaft Timing (VCT), which is the Dodge version of variable valve timing. This V8 is capable of producing 395 hp and 410 lb-ft of torque in the Ram 1500.
Being inefficient on gasoline due to its massive combustion chambers is a common complaint about the HEMI. Dodge engineers came up with a multi-displacement system (MDS) that, whenever possible, turns off half the cylinders to remedy this issue. Additionally, Ram trucks can be ordered with the eTorque mild hybrid system. To conserve gasoline, this system has an electric starter/launch engine. The resulting 2021 Ram 1500 is capable of 19 mpg combined and 17 city/23 highway mpg. The Ram 1500 with a 5.7L HEMI engine is capable of pulling 11,610 pounds.
What makes the Toyota 5.7 so excellent?
You’ve probably heard of engines like the 22 R-E, 2UZ-FE, and 1GR-FE if you’re a serious Toyota aficionado. The reliability and usability of Toyota’s trucks and SUVs were really cemented by these engines. However, Toyota debuted their largest engine to date in 2006: the 3UR-FE 5.7L V8.
One of the best engines for a full-size pickup truck or SUV is the Toyota 5.7 V8. It has been utilized by Toyota for the past 14 years with good reason: it provides both dependability and outstanding performance data. The engine’s poor fuel efficiency is its sole serious flaw.
Key Points
- For the Toyota truck, repairs are inexpensive.
- Typical issues with high mileage Ball-joint failure and exhaust manifold leakage are Tundra problems.
- Although two Toyota Tundra owners exceeded the million-mile barrier, most drivers should anticipate that their Tundra will achieve its maximum mileage of roughly 300,000.
