RST Special Edition Brings Street Look and Power to the New Chevrolet Tahoe and Suburban

Tahoe RST available with 6.2L V-8, 10-speed automatic transmission and Magnetic Ride Control

DETROIT — Today, Chevy introduced a new special edition for the Tahoe and Suburban: the street-performance Rally Sport Truck, or RST. The Tahoe RST will also be available with a new Performance Package that includes a 420-hp, 6.2L V-8 engine; Magnetic Ride Control with performance calibration; and an all-new Hydra-Matic 10L80 10-speed automatic transmission.

"Chevrolet has continually invested in Tahoe and Suburban, developing models with varying combinations of capability, technology and performance to meet the needs of different customers," said Sandor Piszar, Chevrolet Truck Marketing director. "The RST is designed for customers who want a street performance look without sacrificing capability or refinement, along with the option of increased performance as well."

RST will be available on Tahoe and Suburban models in the fall of 2017. Inspired by aftermarket trends, virtually all chrome trim has been eliminated for a street performance appearance. Changes include body-color grille surround and door handles; gloss-black grille and mirror caps; black roof rails, window trim, badging and Chevy bowties. RST also includes exclusive 22-inch wheels wrapped in Bridgestone P285/45R 22 tires.

Available upgrades for Tahoe and Suburban RST include a Borla performance exhaust system that offers a 28 percent improvement in exhaust flow, for a 7-10-horsepower gain at the rear wheels. An available brake package features massive front red Brembo six-piston, fixed aluminum calipers with brake pads clamping on larger-than-stock 410 x 32mm (16.1 inch x 1.3 inch) Duralife rotors coupled with a 84 percent increase in brake pad area and a 42 percent increase in rotor area to increase system thermal capacity. Duralife™ rotors feature a hardened surface to reduce corrosion and provide quieter braking with less vibration.

The Tahoe RST will also be offered with an exclusive Performance Package that includes Magnetic Ride Control with performance calibration, 6.2L V-8 and the new 10L80 10-speed automatic transmission.

This is the first time Tahoe will offer the 6.2L V-8, which delivers an estimated 420 horsepower and 460 lb-ft of torque. The engine features three state-of-the-art technologies — direct injection, Active Fuel Management and continuously variable valve timing — to make the most of power, torque and efficiency across a broad range of operating conditions.

The 6.2L V-8 will be paired with an all-new 10-speed automatic transmission. With smaller steps between each ratio, the transmission maximizes engine power under acceleration. With a wide 7.39 overall gear ratio spread and lower numerical top gear ratio, the transmission also improves efficiency by reducing engine revolutions at highway speeds.

Based on preliminary estimates, the Tahoe RST Performance Package will offer a towing capacity of 8,400 pounds and the truck will be cable of 0-60 mph acceleration in less than 6 seconds. Full performance metrics will be announced closer to launch.

Magnetic Ride Control is an active suspension that "reads" the road every millisecond, triggering damping changes in the electronically controlled shock absorbers in as few as 5 milliseconds. As a result, the suspension delivers both improved body-motion control during cornering and a more comfortable ride while cruising. The new performance calibration included in the Tahoe RST Performance Package increases body control for even higher levels of responsiveness and comfort.

"When you want to hustle, it is incredibly fast, with significantly higher levels of acceleration, braking and road-holding grip," said Eric Stanczak, chief engineer for Chevrolet full-size trucks. "When you want to relax, it is very refined, with exceptional ride comfort and interior quietness."

Chevrolet has been the best-selling full-size SUV brand for 42 years. Today, Tahoe and Suburban are the top two vehicles in the segment. They also account for 49.3 percent of retail sales, or nearly one out of every two full-size SUVs Americans bought in 2016. Tahoe and Suburban customers are also the most loyal owners in the segment, with 79 percent of owners replacing their vehicle with another Tahoe or Suburban.

I need this in my life with a nice 2-4in drop

I like those wheels.

I don't know what to make of this one. Coworker has a Silverado. When I rode in it, the last thing I thought it needed was more HPs

Yeah my uncle bought a Silverado with the 5.3L V8 (and 6-speed auto IIRC) and it felt great. Could easily break loose the rear wheels and could tow his equipment trailer with ease, I was impressed.

But folks love their SUV's and some folks will always want to "one up" their neighbors so I suspect this will be a good seller for GM.

[MX793]

For someone who tows (boat, horse trailer, large camper), the 6.2 will be a better engine than the 5.3.  I get offering the bigger engine.  For those who just carry passengers, I suspect few have complaints with the performance of the 5.3.

[giant_mtb]

5.3 is great, 6.2 is greater. 

[12,000 RPM]

By 0.9 I believe

[FoMoJo]

Only 420 bhp? 

Needs a Voodoo.

[Gotta-Qik-C7]

Only 420 bhp? 

Needs a Voodoo. LT4

[MX793]

Needs a Voodoo.

Voodoo's got no torque.  A regular 5.0 with 3.73 gears will outpull a Voodoo in a top-gear pull from 50 mph despite actually having slightly taller gearing.

[MexicoCityM3]

The Tahoe is the 2 row and the Suburban is the 3 row, right?

I think a Suburban may be in my future as a Mexican Lampoon Vacation road trip car after baby #2 arrives (we'll start working on that soon).

They both have 3rd rows.

What's the difference then?

[MX793]

What's the difference then?

Suburban is bigger.  More space in the passenger cabin, more cargo space behind the third row.

I see, when the time comes I´ll take a look. Monika and I got a new Suburban as an Uber black the other day on a date. We liked it a lot.

With a 10 speed who needs a truck load of torque?

Besides, I'm just razzing him; cheeky little bugger .

Nice looking bus.

They make excellent long-distance cruisers for more than two people...

We averaged 23mpg highway in our rental and that was the old 8speed. 

And no, some people don't care.  We are also talking to someone who has a V10 m5 and twin turbo V8 X5 among other gas hogs

23mpg for a truck that size is more than reasonable. I've gotten up to 25 out of the X5 but making a big effort at eco-driving.

[12,000 RPM]

Best mileage I ever saw in my Z was 26 MPG so 23 out of a brick with twice the frontal area and weight is damn good

I get the appeal of the bigger engine and even Magnaride, but the pitch of this thing's added dynamic prowess is still ridiculous to me. I've ridden in a few GMT900 vehicles.... unless the K2XX is some kind of revelation I still imagine these things to be living rooms on wheels. One vehicle I would not put coilovers on.

[MexicoCityM3]

Intake? Wider tires? Come on, don't let us down!

[giant_mtb]

You can say that about any vehicle.  Nobody buying a Tahoe thinks they're gonna get amazing mileage.

Just lowering springs.

That way you keep magnaride

GM big cars are shockingly thrifty at speed.

[68_427]

Well the Yukon was revving like 1800rpm at 80mph and possibly running on 4cyl

[12,000 RPM]

That's still like 4.6L

[68_427]

That's still like 4.6L

How does a 5.3L running on half it's cylinders equal 4.6L?

Bad math.
