I-Force Max Is The New V6 Engine For The 2022 Toyota Tundra

The new 3.5L twin-turbo V6 – The i-FORCE

This new design incorporates an aluminum block with a displacement of 3,445 cc via an 85.5 mm bore and 100 mm stroke. The 24-valve, Dual Overhead Cam V6 is chain-driven and features Dual VVTi systems. When dealing with turbos, heat is always a concern. Toyota has addressed this thanks to the water-cooled intercooler keeping turbo temperatures down. Toyota engineers have developed state-of-the-art cylinder heads for max-boost reliability with a two-layer water jacket structure for max coolant flow and combustion chamber strength. Then they added machined cross-channels for additional combustion chamber cooling. The intake ports use a low-profile, laser-applied powder-metal to allow more coolant flow closer to the spark plug. As for exhaust cooling; the engine uses a computer-optimized exhaust valve shape, integrated exhaust manifold and cylinder head design that uses the same water jacket to lower exhaust gas temperature entering the turbochargers.

Those new cylinder heads (with cross-channels) are said to contribute to cylinder head reliability and operating efficiency.

How powerful will the i-Force Max be?

The standard engine in a 2021 Toyota Tundra is a 5.7-liter i-Force V8. The i-Force Max should be a dramatic improvement over that standard V8. According to MotorTrend, the 2022 Tundra will debut with two brand-new engine options. The optional engine, in particular, is supposed to be pretty amazing, at least according to Toyota.

In any case, the first engine is the i-Force Max. It will probably be the Tundra’s standard engine, and it’ll probably be a twin-turbocharged V6. On the other hand, the optional engine will likely be the Hybrid Max, which MotorTrend said could be a powerful hybrid option. Though little is known about the i-Force Max, it’s possible to look at similar engines available on other Toyota models.

For example, the Land Cruiser has a similar engine, and it produces 409 hp and 479 lb-ft of torque. If the new Tundra gets those specs, they would be a huge improvement over the old Tundra’s V8. As far as efficiency goes, that’s also up in the air. Because so little is known about the 2022 Tundra, it would be impossible to get a fuel mileage number until Toyota releases the official numbers. That said, the Hybrid Max engine option should definitely be more efficient than usual.
