The Dodge Ram with the Cummins turbocharged diesel engine has long held a legendary status among truck enthusiasts. But the third-generation (2007.5-2012) models represent a particularly significant chapter in this enduring saga. This isn't just another pickup; it's a powerful, reliable, and highly modifiable machine that continues to capture hearts and minds. Let's delve into what makes the third-gen Dodge Cummins so special.
The Heart of the Beast: The 6.7L Cummins ISB
At the core of the third-gen Dodge Cummins lies the remarkable 6.7L Cummins ISB engine. This isn't just an upgrade; it's a complete redesign compared to its predecessor. This powerhouse boasts:
- Increased Displacement: The jump in displacement from the previous 5.9L significantly boosted torque and horsepower.
- Common Rail Injection: This system delivers precise fuel injection, leading to cleaner emissions and improved fuel efficiency (relatively speaking, for a diesel!).
- Variable Geometry Turbocharger (VGT): This allows for optimized performance across the RPM range, maximizing both low-end grunt and high-end power.
- Exhaust Gas Recirculation (EGR): While controversial among some enthusiasts, EGR plays a critical role in reducing emissions.
This combination of advancements resulted in a truck that delivered class-leading towing and hauling capabilities, while also offering improved drivability compared to earlier generations.
