Silverado 4500/5500 coming next year.

Bonus: it went in for service...so far, the tally is a bad EGR cooler, a clogged DPF, and two gallons of diesel fuel in the oil. If the repairs are less than ten thousand dollars, I will be stunned.

None of the emission diesels are prizes. I wasted an hour yesterday doing a regen on my work truck...it probably needs a DPF, to the tune of six thousand dollars.

Exactly what I was thinking. And I'm a bit surprised there's no gas engine option.

GM no longer has a big enough gas engine for this type of truck and is missing a huge opportunity because of it.

You are correct about the Maxforce engines; we have a few of them at my work and they run so rough when cold it's ridiculous.

Don't care. No truck is worth 50-70K. I will keep my 2500 Duramax as long as I can buy parts and rebuild it. Cost's me about 5 Grand a year for parts and insurance. Fuel is always necessary, Cow Pee, (Urea) is not.

Although they will not come here . Petrol engines have ceased to exist in this class of Truck in Australia since the early 1950's. Interesting they are offered in the US

And Petrol engines here in the US have made huge gains and improvements since the early 1950's while diesel engines have become very complex with their emissions system.

Every U-Haul truck that's running Fords latest medium duty trucks are equipped with a gas engine because it's cheap, UHaul doesn't care about fuel economy, and fueling mistakes by their customers is a non issue. As a matter of fact Ford will be producing a 7.0 V8 engine at the Windsor factory which will replace their V10. I'm sure GM is paying attention to Fords recipe and will mimic it when the times right, but I think their partnership with Navistar is to get their foot back into the door and into this market which they never should have left.

All engines have made huge strides since the1950's ( in fact everything has) stll the status quo is the same. Diesels have made HUGE strides. Now there is one Petrol engine for Asian sourced Pickups, several years ago there were some like the V6 4 Litre Toyota engine and the very basic 2.7 engine. Now the 4 Litre has been dropped. 99% of sales are diesels

I keep waiting for GM to release a new hd gas motor. Maybe it will come when they release these new med. duty trucks, but if they are they are keeping it pretty quiet.
