Ram didn't provide horsepower specs for the new Cummins engine, though. The outgoing engine made 385 horsepower. If Ram and Cummins were able to get such a large boost in torque, odds are that horsepower has also increased. There's also a good chance that even with more power, the updated Cummins may not exceed the horsepower ratings of the Ford and GM trucks. The Ford is currently second place in power with 440 horsepower, and the GM trucks have the most with 445. Final specs on horsepower, as well as pricing will probably appear soon, since the trucks will be arriving at dealerships at the end of August.
