The world is full of surprises. From Cleveland Browns at Week 16 to the persistent unpredictability of Elon Musk's Twitter account, emotions and fear abound on this planet. To know what else was surprising? Last week, it snowed in Vegas. For once, there were a lot of toques on the strip.
Which is do not A surprise is that the new Ram Heavy Duty pickup trucks are as desirable as their half-ton brothers, especially in the new staggering cabin. What does 1,000 lb-ft of torque look like? Can he carry the mail?
You bet that your Golden Nugget poker chips can.
Developing an engine producing 1,000 lb-ft of torque was not an easy task. Your author was expecting Ram to be the first manufacturer to exceed the four-digit torque cap of a mainstream truck. C & # 39; not completely surprising. What is surprising is the speed and speed with which it appeared, not to mention the maneuverability of a machine capable of pulling a house from its foundations.
So let's dive into the heart of the matter. Putting the right foot on an accelerator pedal that masters the four-digit torque is the closest thing that most hardcore truck reducers will learn to fly a nuclear bomb like Dr. Strangelove's Major Kong. The traction shaft is apparently bottomless, with a lightly loaded and dynamic truck like a Freightliner.

I say "lightly loaded" but, in fact, a gooseneck in the bed of the $ 35,300 Laramie Longhorn Crew Cab and Crew Cab at $ 86,300 was a trailer whose total weight exceeded 21,000 pounds. With a total weight of 4.5 Hellcats on board, the 6.7-liter Cummins 6-cylinder inline-6 diesel engine has made good use of its 6-cylinder engine at the top – a 6% rating – which does not seem much so much that you have not taken a narrow windy road. brake to get the work done, sometimes close to bouncing off the speed limiter. It's aggressive but reassuring; your author never felt like he was about to fall victim to a fleeing truck. Walking on the noisy pedal, the Ram HD maintained its speed and accelerated with momentum on all parts of the course, with the exception of the steepest. It's a big mill.
And that's the fundamental principle of Ram's efforts with this truck: trust. By having the truck perform a good deal of the work, judicious use of the exhaust brake made it easy to hold the truck at 40 mph without having to operate the friction brakes like a frenzied televangelist. Speaking of which, the brake discs hanging on the rear axle measure 365 mm (14.4 inches), while the fronts measure 360 mm (14.2 inches).
How did Ram manage to enter the 1000 Club? It is important to note that not all Ram HD is created equal. The new Cummins 6.7-liter turbo diesel engine in the new Ram 2500 and 3500 Heavy Duty 2019 is available in two variants. The standard output is 370 horsepower at 2,800 rpm and "only" torque at 850 lb-ft at 1,700 rpm. The high-performance crusher, installed in the 3500 truck and making all the headlines, produces 400 horsepower at 2,800 rpm and 1,000 lb-ft of torque at 1,800 rpm.
Rod Romain is the chief engineer of Ram Heavy Duty and has a golden radio voice that sounds like a truck. Seriously. If a truck with 1,000 lb-ft of torque could talk, it would do so in the soft, gravelly tones of Rod. He explained the multitude of changes undertaken to reach 1,000 people.

The changes begin at the heart, with a cast iron cylinder block with compacted graphite. By using compacted graphite cast iron instead of cast iron, a cylinder block is obtained which is supposedly stronger and better able to dampen vibrations. It weighs a little less, because the new plant weighs about 60 pounds less than the engine of the previous generation.
A new cast-iron head is based on the new block with modifications that include new exhaust valves and new springs, as well as new rockers driven by a hollow camshaft, which helps reduce weight. New oil and water pumps with aluminum casings accompany the ride, as well as lighter, more durable pistons that connect to the crankshaft through new forged rods and new bearings. Attention: the new turbo diesel has an inside diameter of 4.21 inches and a stroke of 4.88 inches, while the compression ratio is 16.2: 1 for high flow and 19.0: 1 for the standard rate. The boost reaches its maximum at 33 psi.

So we know that all of this works well by carrying about 21,000 pounds. But what about big guns? The number of 35-pounder rings that Ram keeps throwing out there? To find out, we hitched a gooseneck of 11,500 lbs., Loaded with 15,810 lbs of backhoe and 7,790 lbs of breeze blocks. Presto: 35 100 pounds
Predictably, this halo figure is limited to only one truck style, namely a Tradesman 3500 Regular Cab 4 × 2 at $ 56,800 with two rear wheels. There were fabric seats and a Uconnect screen the size of an iPhone. You strange ones would have liked it. Anyway, on the same 6% slope, going down 1,801 feet by 5.4 miles, the exhaust brake showed a similar tendency to curb the huge amount of descent created by this truck and its trailer .
A half-turn near the end of the slope, entering the fresh air of Nevada revealed no flames of burned brake fluid or over-cooked rotors. Back on the saddle and steering the Merchant up the hill, the white dualie of the contractor dragged him to steer the slope with determination. Bury the strong pedal in the carpet vinyl on the steepest slopes of the course resulted in a constant speed of 35 mph. With 35,100 pounds in tow, he gained speed as the ground leveled off.
All of this is fine, but what about real world surprises? You know, things that most drivers will see and use every day. For starters, the narrow convex side of the Ram HD side mirrors – mounted separately from the standard rear view mirror, as on most trucks, is motor. This does not seem to be very serious for those who do not tow regularly, but as a TTAC resident carrier, I can tell you that this detail is a huge step forward. Gone are the days when you had to lower the window, lay on the cab, put a greasy thumbprint on the convex glass to make a setting … only to make the angle off once it returns to the normal driving position. This is an example of a concrete problem that has been solved with a few dollars and a dose of common sense.
It is also in this context that the new online heating systems are integrated into the ventilation network of Ram HD equipped with Cummins. These units generate heat for the cab without having to wait for the endless engine time to generate a few BTUs.
The 12-inch mahoosif infotainment display is available in a number of versions, not just in high-end models. That includes, I'm happy to report, the Power Wagon, with its bench bench and baseball bat with a 4 × 4 lever coming out of the ground. It's a wonderful mix of tradition and modernity.
Three cabin sizes remain, including a 142 cubic foot Mega Cab variant that is so large that annual truck maintenance includes the verification of hibernating bears. Few companies are able to offer a wide range of versions and styles added to the same truck as Ram. Limited and Longhorn are alter-egos, for example, while well-equipped Laramie trucks have suede touches. There is a quintet of USB ports, auxiliary switches that look like rubber-coated chicks and infused with maple syrup, and wireless smartphone charging in some models.
There is now a button-like button transmission in the Hemi brand 6.4-liter gas HD HD, thanks to the addition of a well-known eight-speed automatic. Completely empty with the exception of two well-fed journalists, a 4 × 4 Laramie Longhorn Crew Cab and $ 35,000 cashier equipped with this engine reported about 15 mpg in your author's hands on a long road . Active louvers behind this large grille certainly helped. Diesel customers always have the option to change gears via a column selector that springs from the steering column like a larch overgrown with vegetation.
Technology such as automatic emergency braking, which was once the domain of luxury sedans, has been found on the Ram HD. This system remains functional even when a loaded trailer is connected, as emergency braking integrates the trailer brakes, so that a complete panic stop is available even during transport. The adaptive cruise is part of the transaction and helps reduce driver fatigue.
In fact, most of the technologies that Ram's engineers have incorporated into the new HD sensors have been designed for this purpose: to reduce fatigue. An alert and rested driver is a safer driver, so he thinks, and it's hard to argue this statement.
Extraordinary power, bold pace and sumptuous interior – it is perhaps not surprising that Ram passes GM to occupy second place in the truck market, as desired by his goal.
Snow in Vegas, though? Color me stupefied.
