We may be winding down the year, but Chevrolet has one more surprise in store for everyone before the decade ends. It's the next-generation Suburban and it's one of the most important launches for the brand, too. Not only that, but they've also revealed the all-new Tahoe as well, the “shortened” version of the Suburban.

Given that Suburbans (and Tahoes) typically have long life cycles, it's a bit of surprise that they're introducing an all-new one after just five years. However, the platform used on the current Silverado is totally new; it was only a matter of time before the Suburban and Tahoe shifted to what they're now using. Dubbed the GM T1 architecture, the 2021 Suburban and Tahoe

The all-new Tahoe and Suburban now have similar front ends with their pick-up counterpart, the Silverado. It has the new 'hourglass' grill shape from the pick-up, but the headlights get a totally different treatment. Gone is the quad-light design that has been a signature of the two full-sized SUVs since the late '70s (mid-90's for the Tahoe), and are now replaced by a high-mounted pair of headlights.

The flanks of the two, on the other hand, appear more evolutionary than revolutionary. Much like the previous generations. It's tall and upright, providing a lot of glass area. There are slightly more details however, namely more character lines on the doors to add to a more robust side profile. The same goes for the rear although the tail lights now have more edges than the older models, replacing the conventional rectangular units.

Several variants and appearance packages are available for both. Aside from the usual LS (base) and LT (mid), there are also four more versions that can be ordered. The Premier is a plusher, better-equipped version of the LT, while the High Country veers more towards luxury. For those who want to make their SUV look more sporty, there's also the RST package while off-roaders will be pleased to see that the Z71 pack is still around, complete with a factory lift kit and other off-road essentials.

But the most dramatic change can be seen under the chassis. For the first time ever, the Tahoe and Suburban come with independent rear suspension. GM says that this helps make the interiors more spacious than before and it allowed them to increase cargo space and, more importantly, third-row legroom. Much-improved handling and road-holding are also to be expected.

To conform with today's tech-savvy customers, Chevrolet installed larger infotainment displays on both the Tahoe and Suburban, as well as put in more wireless connectivity features. A new 10-inch touchscreen media display is standard across the range and features built-in Wi-Fi hotspot with 4G LTE, Apple CarPlay, and Android Auto. Drivers can also benefit from a 15-inch diagonal heads-up display that is available as an extra.

Also available is the optional rear entertainemnt system for the second- and third-row passengers. The system is comprised of 12.6-inch screens with each offering independent connections so passengers can watch different content on each side. In addition, rear passengers can also share content from one screen to the other by way of 'mirroring' via Android. They can even send navigational points of interests towards the center infotainment display up front.

Other noticeable changes inside the Tahoe and Suburban are the revised automatic climate control panel, new-style multifunction steering wheel, updated instrument cluster, and new upholstery trim and color options.

Given that the Silverado, Suburban, and Tahoe would share the same engines (for the most part), it's largely the same story for this generation. It starts with the 5.3-liter V8 which is available for the LS, LT, Z71, and RST. It produces 355 PS along with 519 Nm of torque. Next up is the larger 6.2-liter option for the Premier, High Country, and RST. It makes 420 PS and comes with 623 Nm of pulling power.

However, there is one new addition that should prove interesting. Instead of bolting on the large capacity V8 turbodiesel from the Silverado HD, there's now an option of a 3.0-liter, inline-six turbodiesel. While it may only produce 277 PS, its torque output is similar to that of the range-topping 6.2-liter V8. We sure hope that Chevrolet Philippines considers bringing that engine here, should they actually bring in these SUVs.

Aside from making the two SUVs bigger and more high-tech, Chevrolet also expanded their safety features as well. The two are available with automatic emerency braking, forward collision alert, front pedestrian braking, 360-degree surround-view camera, lane change alert with blind zone alert, front and rear park assist, hitch guidance for trailers, and lane keep assist.
