The close connection between Ram and Cummins goes back three decades. The latter company’s famed diesel engine was first lowered into a Dodge Ram pickup in 1989.
There have been any number of milestones attained over the years, such as the first 200-hp engine (1996) and the first to deliver 500 lb-ft of torque (2001); recently Cummins offered up its first engine to deliver 1,000 lb-ft of torque.
In fact, the latest engine to be developed by Cummins is a 6.7L inline-6 unit, which generates 400 hp and has had the honour of being the first to offer those 1,000 lb-ft of torque. Not only that, but compared to earlier engines produced by the company, it is more fuel-economical and quieter and delivers smoother performance.
Light years removed from the rustic engines of three decades ago.
As for the three-millionth Cummins engine, it is to be fitted very shortly into a 3500 Longhorn Crew Cab Dually 4x4 truck.
We’ll go out on an incredibly short limb and predict that the fruitful Cummins-Ram marriage is not about to end. Though when you look further out on the horizon, say to 2050, things are less cast in stone. Given the current flux in the industry, it’s likely the automotive universe is going to look radically different in another 30 years.
