TURBOMAXTM ENGINE
TWO POWERFUL FORCES COME TOGETHER

The TurboMax™ engine delivers 310 horsepower, 583 NM of standard torque, available max towing of up to 4,305 Kgs1. and a 3 years / 100,000 Km Powertrain Limited Warranty2. Standard on SLE and Elevation.

TURBOMAXTM ENGINE PERFORMANCE

TURBOCHARGED CAPABILITY

The TurboMax™ engine delivers the capability you demand when you need it most by providing next-level performance and low-end torque.

COMBUSTION PROCESS

The TurboMax™ engine offers powerful diesel-like performance while running on regular fuel. A multi-hole direct injection with up to 2,900 psi of pressure helps maintain high efficiency.

TURBO DESIGN & INTEGRATION

An inline 4-cylinder arrangement provides a symmetrical natural turbo placement. Large cylinders feed into a near-equal-length integrated exhaust manifold that couples with the dual volute turbo. That means you get exceptional responsiveness and turbo boost performance.

AIR COMPRESSION & COOLING

A large-charge air cooler acts as a mediator between the turbo and engine. This feature takes warm, compressed air and cools it down before reaching the engine, which helps increase efficiency and power for optimum towing capability in hot conditions.

A SUMMARY OF PERFORMANCE

What makes the TurboMax™ engine so appealing is its remarkable high-power output, fuel efficiency and 430 lb.-ft. of torque. It’s a product of rigorous testing and real-world trial that’s ready to work for you, and it shows.



TURBOMAXTM ENGINE DURABILITY

FULLY FORGED BOTTOM END

Heavy-duty durability starts with a strong foundation. The engine has a fully forged-steel bottom end, starting with a stiff forged-steel crankshaft and supported by forged-steel main bearing caps.

DIESEL ENGINE TECHNOLOGY

The TurboMax™ engine is designed to take on heavy loads with turbocharged power. That’s why it’s equipped with diesel technologies, such as tri-metal rod bearings, pistons with a fully machined crown and a cast-iron ring carrier supporting a physical vapor deposition (PVD) coated steel top ring.

DESIGN & BUILD

The hydraulic tensioners reduce chain drive stress and high loads on chain drive systems to provide the durability you’d expect. The lower crankshaft extension helps support the main bearing caps, giving the engine a strong foundation to handle heavy turbocharging loads.

THERMAL CONDUCTIVITY

Cast-iron liners provide a durable wear surface for the rings, which is critical for long engine life. A locking interface helps move heat out of the cylinder to the water jacket where cooling occurs. Sodium-filled exhaust valve stems and high thermal conductivity valve seats and guides help keep exhaust valves running cool in extreme, high-performance situations.​

TURBOCHARGER LUBRICATION & COOLING

Keeping the turbocharger lubricated and cool are the keys to a long engine life. Symmetrical natural turbocharger placement allows for priority feed oil from the filter and optimized coolant routing, which helps the turbocharger cool after shutting down. And under extreme conditions, the electric water pump can provide after-run cooling.
