There it is Folks: Ram HD Fourth Generation.5

Attention: TDR Forum Junkies
To the point: Click this link and check out the Front Page News story(ies) where we are tracking the introduction of the 2025 Ram HD trucks.

Thanks, TDR Staff
Spied. The 2020 Ram HD.

First, visit The Truth About Cars for their take on it.

Now here is a letter from the editor that is being typeset for TDR Issue 103.

RIGHT OR WRONG: HOW 'BOUT THAT FOURTH GENERATION.5 (4G.5)

Was I right? Was I wrong?

• This magazine was sent to the printer on 12/28. In this issue I have written something about a new Ram HD.

• This magazine was sent to press on 1/14. We’re about to print something about a new Ram HD.

• The folks at Ram/Cummins are in attendance at the North American International Auto Show (NAIAS) to unveil something on 1/14. By now my prediction is in ink.

• Your magazine arrives early-mid February and you either laugh at the editor’s prediction and/or you give his new nomenclature idea your consideration.

Okay, you may have missed it. I presented a nomenclature idea that I shared with you in the previous, Issue 102, magazine. This new nomenclature goes hand-in-hand with my prediction: You now have a Fourth.5 Generation Ram/Cummins with a new 6.7-liter, compacted graphite iron (CGI) block. This new engine gives us 400 horsepower and 930 torque.*

The following is from the last issue:

“Think back to 1/1/2007. If you will recall, Cummins met the 2010 emissions requirements with their new ’07.5 6.7-liter engine. As I’ve picked up from reading the Columbus, Indiana Republic newspaper and from watching Cummins for the last 30-or-so years, they are proactive, hence there will be a complete engine redesign for 2019.5.

“We’ve all done this mid-year emissions-rule-change/engine hardware- change song and dance before, haven’t we? Year '91.5 saw a change to the engine with the addition of a charge air intercooler. Year '98.5 saw dramatic changes as a different cylinder head (24-valve) and an electronic fuel injection pump were added to the engine. Year ’07.5 gave us the entirely new 6.7-liter engine and the addition of emissions aftertreatment components.”

So, borrowing the nomenclature idea used by others in the automotive world to designate changes that occur within a chassis/ cabin “generation”, here is what I would propose.

First Generation 1989-1991
First Generation.5 1991.5-1993

Second Generation 1994-1998 (12-valve models)
Second Generation.5 1998.5-2002 (24-valve models)

Third Generation 2003-2007 (5.9 HPCR models)
Third Generation.5 2007.5-2009 (6.7 HPCR models)

Fourth Generation 2010-2019 (6.7 HPCR models)
Fourth Generation.5 2019.5-??? (6.7 CGI models)

What do you think?

Truthfully, if TDR owners adopt the nomenclature it will stick. I will try to rename the columns on our web Forums. I have already renamed the columns in the magazine.

Am I right? Am I wrong?

About 70% of engine internals have been upgraded and will not work in older engines.Hollow billet camshaft with hydraulic roller lifters.Larger piston pins,pistons rods and rod bolt changes to match.Higher pressure cp4.2 injection pump.Difeerent fuel rail(dual supply line),Different injectors.Lower compression ratio,different head gasket,diferent egr valve,different turbo and more that I know I have probably missed
