Ram Jeep "Tornado" Twin Turbo Straight Six Announced

[RooflessVW]

I like that one. Looks good also as Ramjeepdodge.

Better than Xeljanz or whatever they're called now.

And the motor is removed by Stellantis from the engine plant production listing.

Disappointed that they never turboed the Pentastar. That was supposed to have been a designed in option when it was released.

Indeed! Had they done that, the Tornado would not be needed. I am looking at a supercharger for mine in the near future.

So what? I doesn't matter why it's selling. The fact of the matter is, people are buying them by the thousands because they want them. You don't stop making a product that has had an excellent track record in sales for almost 2 decades. As I said, not everyone wants tiny screaming engines with turbos bolted all over them, stuffed under their hood.

The fact that it's "dated" is also good. People like products with a well proven track record. Especially today with all of the crap the auto industry is turning out. The pushrod V-8 design has proven itself over decades, and literally tens of millions of miles, in millions of vehicles. It's all but the perfect power plant for full size trucks, and large SUV's. The sales numbers prove that.

It matters because for every Hemi Stellantis sells, they have to buy carbon offset credits from Tesla to sell the next one.

I'm sure Stellantis would rather have that $2.4 billion FCA spent in offsets to stay in the assets column of it's own balance sheet rather than Tesla's.

They shouldn't have named it the Tornado. That's a special engine that has it's own place in Jeep history.

That said, Ford has wrecked the 5.0L with cylinder deactivation. Junk.
I would likely jump ship if this engine is an option in the Ram. I love the interiors, but both the guitarist and sound guy in my band have new Hemi's and they tick. The sound guy fired up his '20 after an August outside gig and it sounded like a sewing machine.

The sewing machine sound is pretty normal, due to the valvetrain geometry of the engine, that's not the "tick", the "tick" sounds like an exhaust leak (and often IS an exhaust leak).

So basically they're copying the BMW N54 from 2007.

Assuming it's a closed-deck design the tuning crowd is going to have a field day.

I thought they were copying the Mercedes M103 from 1984…but whatever…a 3.0 liter straight six is hardly new architecture.

I was kinda of joking when I said that but I suspect it's going to be very similar to the N54. The N54 has the exact same layout with two small turbos feeding 3 cylinders each w/direct injection. I'm assuming the Chrysler plant will also have VVT just like the N54. Almost every automaker has implemented some sort of VVT system these days. Expect great throttle response, wide flat torque curve, and good mpgs. The only potential issue is cost and reliability. BMW addressed that by ditching the two individual turbos for one twin-scroll (N55).

"The 300 cu in (4.9 L) six was added for the F-series in 1965".

About the only thing older on this car than the engine design, is the guy driving it. Alain Castellana is my age, (69), and he could still drive like this just 15 years ago. I'm sure today he's still not too shabby. No paddle shifters either. His hand goes to the stick for every shift. 3 liter six's are yesterday's news.

I was talking 3.0 liter.

Six cylinder in line engines predate that Ford by several decades.

Packard first built their six, an inline six, in 1913.

Because those engineers over a hundred years knew all about primary balance, smoothness, and power delivery. They advertised those qualities in 1913.

300..... 3.0..... Who's counting?

Who's counting?

Everybody. That's the whole point.

Their competition already has more modern powertrain options. The 5.7L HEMI is NOT the main reason people are buying the Ram.

Maybe - but it's the thing I find most attractive about the Ram.

Well, help me understand the appeal of the HEMI. It is easily the weakest link of that truck, IMO. The engine is dated on power, thirsty and not exactly known for exemplary reliability.

The ZF 8-speed, interior finishes and ride quality are the Ram's strongest qualities. Unfortunately the competition has begun to catch up.

Lots of people on this board even are concerned about "modern" powertrain options. A port-injected pushrod engine has a desirability aspect that appeals to that crowd. People likely expect low TCO with the powertrain combo and generally, with what I've seen with our work fleet, that bears out. The trucks haven't really needed anything other than brakes, tires, oil changes and manifold studs in 200,000 miles.

Define "modern"? You're not buying furniture. The fact is it's the most popular engine in the Chrysler lineup. People wouldn't buy it if they didn't like or want it. And besides, since when did engines come with expiration dates on popularity? If it's selling well, and the 5.7 HEMI is, you don't mess with success.

The engine is used in the Ram pickup , Dodge Durango, the Chrysler 300C, Dodge Magnum R/T, Jeep Grand Cherokee, the Dodge Charger R/T, the Jeep Commander, the Chrysler Aspen, the Dodge Challenger R/T, and the new 2022 Jeep Wagoneer. Hard to get more popular than that.

Discontinuing it for something "more modern", is like giving up going to the best Italian restaurant in town, in favor of a can of Spaghetti O's.

Fuel economy, at least on paper, is always an issue. Based on your thought process, Ford would still be selling the 5.4L 3v and Toyota would still be building the 4.7L V8.

I'd liken it more to the 2V, which was reliable (unlike the 3V) but Ford only did one upgrade on the 2V engine (PI), while the HEMI has been upgraded several times, MDS was added, VCT was added, the heads changed, cam changed...etc. At 395HP it's definitely not the most power dense, but it's still a huge step-up from the 260HP the 5.4L 2V was making at its EOL.

The 6.4L is the Grand Wagoneer engine, though there will be other options introduced, including a PHEV combo and full EV in the next year or two. If you think how long GM milked the old SBC architecture and Ford the Windsor one, there's definitely a history to reliable pushrod engines being used for many decades, just being refined.

Why? They're selling like hotcakes in both Ram pickups, as well as in the Jeep Grand Cherokee. Not everyone wants a turbo. Gas has been expensive before, and it will be again. People still want, and will buy low mileage, high performance pushrod V-8's. The 5.7 HEMI V-8 has been one of the best selling V-8 engines since it was introduced in 2003, almost 20 years ago.

The Hemi is a nice engine. every one I know that has one loves the engine.
