2021 Chevrolet Tahoe Review: Duramax diesel is the right power at the right place

The Tahoe has three available powertrains.

When I write car reviews, I don't typically say very much about the engine and drivetrain unless there's something particularly interesting or unique about it.

I believe most car buyers don't really care about things like zero to 60 mph times or how many gears a transmission has. Those are features and statistics, and they're an imperfect measurement of an automobile.

I'm a fan of the Good-Better-Best school of cars, and it looks a bit like a bell curve. There aren't any genuinely terrible new cars sold today, so at worst, you're getting something that's Good. I'll call that the bottom 20 percent of the market. Sometimes these cars have engines that really are too weak and should probably be avoided, and I'll mention that in my review.

Then there's the class of Better, or the middle 60 percent. When I review these cars, I'll include a throwaway line about the engine or drivetrain as it's not worth mentioning in depth. They get the job done, but there's nothing to get excited about.

Then there's that top twenty percent where the magic happens. Whether it's the perfect majesty of a Rolls-Royce V12, the throaty bark of a Lamborghini V10, or even the brilliance of a Toyota Corolla Hybrid's effortless 52 miles per gallon — these are engines worth discussing.

And so it is again with my test car this week: the 2021 Chevrolet Tahoe. We've already reviewed two of the Tahoe's sister vehicles, the GMC Yukon and the Cadillac Escalade. Despite being from the same family, they're definitively different branches.

But under the hood of the Tahoe is an engine that is so firmly lodged in the Best category that I can't help but write hundreds of words about it. It's the 3.0-liter six-cylinder "baby" Duramax turbodiesel that was in the works at GM for more than a decade.

It gives terrific fuel economy (for a giant truck, anyway) and fantastic torque in everyday driving. I find it far preferable to the extraordinarily thirsty 6.2-liter V8 that I had in the Yukon and the Escalade and heartily recommend it to anyone buying a GM full-size SUV or half-ton pickup. That's even more impressive because the 6.2-liter V8 is already an upgrade over the smaller 5.3-liter V8 that comes standard in most Tahoe trims.

It sports 277 horsepower, which doesn't sound like a lot, but horsepower is a poor quantifier of engine performance. Because it's a diesel and because it has a turbocharger, the baby Duramax has gobs of torque with which to pull away from stoplights or accelerate on a hill, or when you're trying to pass someone and you need to accelerate from 55 to 75 mph as quickly as possible.

The Tahoe's diesel engine excels in all these scenarios while delivering an EPA-estimated 21 mpg in the city, 28 mpg on the highway, and 24 mpg combined in the RWD trim that I drove. That's a healthy improvement over the 16 mpg combined from the 6.2L and four-wheel drive-equipped Yukon. It's worth noting that the four-wheel drive diesel fares a little worse, getting 22 mpg combined, but that's still far better than the traditional gasoline engine.

It does all this, and it can even tow up to 8,200 pounds when properly equipped, but most people will never tow anything heavier than a small horse trailer or a boat with their full-size SUV. If you're hauling that much weight on the regular, you've likely opted for a heavy-duty pickup.

The irony of the Volkswagen dieselgate scandal is twofold. For one, some were pulling similar testing shenanigans that Volkswagen was — it's just that VW was the first to get caught. And second, those VW diesel engines were fantastic. They were torquey and excelled in everyday driving, pesky pollution aside.

There's a dirty secret to the horsepower numbers that most carmakers cite: they peak at very high RPMs that average drivers will never reach. But torquey turbocharged engines like this baby Duramax? It generates 95% of its 460 pound-feet of torque at just 1,250 RPM, and then peak torque runs all the way from 1,500 to 3,000 RPM. That means you're in the prime torque band nearly continuously.

In plain English, that means it's way better to drive. It's more fun, it's more efficient, and thanks to all manner of fancy technology, diesel engines aren't weird and finicky anymore.

Yes, you should probably plug it in if you park it outside in frigid weather. But other than that one minor caveat, this diesel is nonpareil.

2023 Chevrolet Corvette Z06 gets reveal date

Chevy draws a line from the Z06 directly to its racing program.

Chevroley

The new Chevrolet Corvettewas a revelation when it was finally announced. The car brought a mid-engine design to the Corvette line for the first time, and put decades of speculation over the shift to bed. We've all known that Chevrolet would eventually release an even higher performance Z06 version of the car, but now we know the date. The automaker just announced that the car will be revealed on October 26.

To build hype for the car's announcement, Chevy released a short teaser video of the Z06 tearing around the Nurburgring. It's clear from the film that the car we'll see in October will be a different beast from its standard predecessor, which mainly comes down to a big change in its powertrain.

The new Z06 is expected to feature a flat-plane crank V8 that will allow it to rev to 8500 or 9000 RPM. The car should see in excess of 600 horsepower from its howling V8, which will be sent to the rear wheels through an eight-speed dual-clutch transmission.



As it has done with other Z06 models, Chevy will bolster the Corvette's suspension and brakes to accommodate higher speeds and the jump in power. The car will be able to carry more speed into corners and stop in a shorter distance than its standard counterpart, which will improve its lap times at the track. Various active and fixed aerodynamics components are also expected.

The C8 Corvette's interior is anything but boring, and the Z06 will carry on with that tradition. We'll still see the long center strip of buttons and controls, along with a digital gauge cluster and nicely upholstered sport seats. The Z06 will most likely get more in the way of carbon fiber and race-inspired trim pieces, but the layout won't deviate from the standard car to a great degree.

The 2022 Nissan Pathfinder arrives on dealer lots this summer.

The 2022 Nissan Pathfinder doesn't have to be capable of rock crawling or deep water fording. What it has to do is service the needs of families in their daily life and give them the opportunity to competently go off-roading on rocky trails should they desire. The new, fifth-generation models does just that and adds in enough nifty features to make it among the most compelling choices for three-row SUV buyers.

The 2022 Pathfinder is thoroughly modern though not the boxy off-roader it once was. The SUV's styling harkens back to that time with a tilted, darkened C-pillar and a return to a more muscular body style. That styling makes straightforward visibility good but for shorter drivers seeing what is immediately in front of the grille is a challenge that necessitates using surround view camera technology (available only in upper trim levels) when navigating challenging terrain.

Under the hood is a 3.5-liter V6 that offers up 291 horsepower and torque - plenty to do the job without complaint. The SUV's nine-speed automatic transmission replaces the continuously variable transmission (CVT) from the previous generation and delivers smooth shifts. Though low-end torque isn't as robust as I like it to be, once up over 35 mph, the Pathfinder's powertrain delivers smooth, powerful sailing.

The redesigned architecture and components underpinning the Pathfinder make it stable on the road and don't allow it to wallow on winding roads. Even off-road, the suspension provides the right blend of stability while the drive dynamics allowing the driver to feel engaged with their surroundings whether on freshly paved roads, city streets, or muddy trails.

Nissan has given the Pathfinder a 6,000-pound towing capacity and even when maxed out the engine's functionality is strong as ever. The transmission can get held up in a gear mid-range when performing this function, however, with 5,000-6,000 rpms registering on the tachometer but a quick release of the gas pedal recalibrates the offering bringing it down to a more traditional 2,000 rpm range.

The eight-seater Pathfinder clearly has the Toyota Highlander in its sights, with good reason. It's the top-selling three-row SUV in the country. Nissan boasts that three adults can fit across the rear bench seat of the Pathfinder and, as long as they're average size or smaller, the marketing talking point holds up. There is gobs more room back there than there is in the Highlander.

Getting in and out of the third row is easy thanks to one-touch buttons on the outboard side of the second-row chairs that move the SUV's captain's seats forward creating enough room to get through to the back. Smartly, Nissan's engineers have put duplicates of these buttons on the back side of the same seats allowing third-row passengers to simply press the button to move the seat up.

The third row can also be accessed via a split between the captain's chairs as well, a space traditionally occupied by a center stowage bin/cup holders/arm rest. Owners can quickly remove the center console by opening a panel on the front and pulling the release mechanism. The one-handed operation takes seconds and the console can be easily stored in the under-floor trunk space behind the third row seat for ease.

Speaking of cargo space... The Pathfinder is one of the most spacious midsize SUVs on the market today for both passengers and cargo. There is a substantial amount of room behind the third-row seat and the under-floor storage area is nearly twice the size of the one in the Highlander. Plus, it has a feature that allows the area cover to be automatically propped up when pushed up by a user. This is especially help when carrying groceries or plants home and keeps them from being crushed.

The first- and second-row seats are suitably comfortable, even for extended periods of time and standard trig-zone climate control makes finding the right in-cabin mix easy. Bottle holders in the pockets of the front doors are exceptionally large, fitting even bulky water bottles.

In front of the driver is a standard tachometer, speedometer, and 7.0-inch driver information display. Buyers can upgrade to a fully digital 12.3-inch instrument cluster and head-up display but they're not reason enough to upgrade to the top-tier Pathfinder Platinum on their own.

Nissan packs the new Pathfinder with a host of desirable features that make living with the Pathfinder easier including one-touch auto up/down windows, a wireless phone charger, grocery hooks in the rear cargo area, USB ports in all three rows, second-row sunshades, rear door keyless entry, wireless Apple CarPlay, and a motion-activated lift gate.

The 2022 Nissan Pathfinder is priced to start at $33,410 for the two-wheel drive S base model and $35,310 for the four-wheel drive S base model. The model tops out around $50,000 with destination and delivery included, which seems fair when comparing the Pathfinder to other vehicles in the market.

If you're thinking of purchasing a Ford Explorer, Jeep Grand Cherokee, Hyundai Palisade, Kia Telluride, Honda Pilot, or Highlander, do yourself a favor and schedule a test drive of the new Pathfinder when it arrives at a dealer lot near you. You may just be surprised how seamlessly it fits into your daily life compared to the competition.
