The 2021 Chevy Tahoe loves the open road!
This big bruiser may be a bit cumbersome in tight urban quarters, but point it down the highway and it comes into its element. Two things in particular contribute to such excellence when long drives call: a thrifty yet powerful diesel engine, and an independent rear suspension.
The 2021 Tahoe comes in six trim levels and drivetrain configurations. There are three engines. The standard engine on all but the top trim is GM’s venerable 5.3-litre V8. The High Country trim gets a 6.2-litre V8.
A new 3.0-litre turbo diesel is a $1,995 option across the board, except for the High Country where it is a no-cost alternate. The beauty of a diesel is two-fold: massive amounts of torque, and exceptional fuel economy.
There is a reason every large commercial truck is powered by a diesel engine!
The new turbocharged six-cylinder diesel produces more torque than the 5.3-litre V8 and matches that of the bigger 6.2-litre unit.
Maximum power is available from the get-go with a diesel, no waiting for the revs to build. Maximum torque of the 3.0 turbo diesel in the Tahoe is produced at only 1,500 rpm, while the gasoline engines have to twist to 4,600 rpm before reaching peak power.
The diesel is rated at 8.9 litres/100 on the highway giving it a 33 per cent advantage over the 5.3 V8 and 40 per cent over the bigger gasoline engine. I easily achieved those numbers with no effort.
It is a bladder buster as well, capable of 1,000 kilometres between fills!
Math was never my strong suit, but it doesn’t take an advanced degree to see where the diesel will pay for itself in short order. In fact, if you order the High Country trim, the 40% savings start immediately.
For the other five trim levels, the added cost for the diesel option is $1,995. After 50,000 km, the diesel will have used 4,450 litres of fuel, 1,450 fewer than the 5.3 litre gas engine. At the time of this writing, regular unleaded gasoline and low sulphur diesel prices were within one cent of each other at $1.43 per litre.
That’s a savings of slightly more than $2,000.
The diesel is the gift that keeps on giving as the Tahoe and its slightly larger Suburban sibling often tally hundreds of thousands of miles. Higher mileage drivers take note.
Vehicles like the Tahoe are often used to tow trailers carrying adult toys. The diesel is right at home in this environment, able to haul up to 8,000 pounds of ‘stuff’.
The new independent rear suspension takes the truck out of the Tahoe. It trades some extreme work ability for creature comfort – as in a much more pleasant ride and a semblance of handling not available with the old solid rear axle.
By allowing each rear wheel to operate independently, the new Tahoe has a more comfortable ride and an alacrity in the turns unheard of in previous generations.
The ability to soak up road blemishes is significantly improved. You no longer have to deal with a rear end that wants to change lanes when encountering a bump mid-corner. The new Tahoe simply soaks it up and maintains its poise.
The other big advantage of the new independent rear suspension is the improvement in interior space.
The Tahoe is a body-on-frame vehicle. With a solid rear axle, the load floor has to clear a giant lump of a differential. The new suspension allows a much lower floor benefitting both third row seating and cargo area. Third row occupants can now sit in a normal manner, without their knees up around their ears. The lower cargo floor makes loading easier and provides greater height for loading below the window line.
The 2021 Tahoe has grown significantly in several key areas. Overall length is up 17 centimetres and the wheelbase is 12.5 cm longer. This benefits both passenger and cargo space. Second row occupants will find a limo-like 107 cm of legroom, 7.6 cm more than the older model. Folks in the third row, in addition to the lower floor, get an additional 26-cm of legroom for a very useful and comfortable total of 88.7cm.
The Tahoe makes an excellent ‘office on the road’. You can find a parking space, plug your laptop or other device into the 110-volt outlet, log onto the included 4G LTE WiFi hotspot and go about your business. A passenger can do the same while underway, whiling away the miles and time.
The 2021 Chevy Tahoe is a great family vehicle, with plenty of space for people and cargo. It also offers plenty of towing capabilities. In addition, the ride and handling are vastly improved.
The frosting on this cake is the availability of a thrifty and powerful diesel engine.
