Chevy Tahoe PicturesFull-size SUVs aren’t as common as they were just a decade ago, but the big names are still towing, hauling, and carrying in ways no crossover can. For the 2015 model year, the Chevy Tahoe signs up for more of that hard work, with a revamped powertrain, a crisp new look, and more comfort and safety conveniences.

Chevrolet introduced the 2015 Tahoe and Suburban – all-new versions of the industry’s best-selling duo of full-size SUVs. They offer more functionality, greater refinement, new safety features and an increased range of advanced technologies to appeal to two distinct customer groups who want the unique combination of features only Tahoe and Suburban provide.The Tahoe sits on a wheelbase 116 inches long; the Suburban’s span is 130 inches. (GMC’s Yukon has the same parallel with the Yukon XL.)

All-new styling advances the Tahoe and Suburban’s design, which contributes to a quieter ride. A more-efficient, direct-injected EcoTec3 powertrain coupled with improved aerodynamics help offer greater estimated highway fuel economy based on GM testing while preserving overall performance and capability.

So, we’ve established that fullsize SUVs aren’t yet dead, Chevrolet and GMC are two of the biggest players in the segment and, importantly, that the market is lucrative. It was with these facts in mind that we slid behind the wheel of the 2015 Chevy Tahoe. Just who is it that are buying up these massive utilities, and what are the specific virtues that lead to their continued success? Let’s find out.

2015 Chevy Tahoe Interior Exterior

2015 Chevrolet Tahoe InteriorThe upright new shape is bold and modern, but it won’t appeal to everyone. The new 2015 Chevy Tahoe is the first example of the model that doesn’t share any of its body panels with the Silverado pickup that shares much of its mechanical bits. This freedom of design has allowed Chevrolet to re-work proportions and details to better reflect modern SUV styling.

Underpinning the crisp exterior lines is a focus on aerodynamics, to help boost gas mileage. But despite the engineered shapes, the overall look still says classic SUV, while draping the bulky form in graceful angles and sharp details. Inside, the look of the new 2015 Tahoe is even more thoroughly revised, with many of the details shared with the pickups, but worked into a form that presents a substantial, durable sensation while also merging more car-like aspects to the control layout and overall shape. Aesthetically, the new interior is head and shoulders above the previous-generation Tahoe, bringing a markedly premium feel through more modern shapes and themes, improved materials, and rich color palettes.

Aerodynamically, the new Tahoe improves on the outgoing model, despite sheetmetal that’s lost almost all the softness introduced with the last-generation Tahoe, back in 2007. The cabin is the relief from all the hard, straight edges that define the new Tahoe: the cockpit, if you can call it that on an eight-passenger vehicle, is soothingly smooth and curved, with an 8.0-inch LCD touchscreen centerpiece and more overt car influences than ever.

GM says it’s put a lot of engineering effort into improving the Tahoe’s functionality, safety, and infotainment features. Third-row access is better because the seats fold flat now, and getting in the way-back is easier thanks to a couple more inches in second-row leg room. The cabin’s storage bins are more useful too, with a center console bin deep enough to hold tablet or small notebook computers. There’s even a power-folding option for the second and third row, making it quicker and easier to convert from passenger duty to cargo-hauling mode.

The Tahoe tops off a revised safety package with GM’s new front-center airbags, on models with front bucket seats. Adaptive cruise control is an option, as are a lane-departure warning system with seat-mounted haptic alerts, blind-spot monitors, forward collision alerts, and front parking sensors.

Other available features include keyless entry; pushbutton start; an 8.0-inch LCD touchscreen radio with Chevy MyLink connectivity; a head-up display; a power tailgate; a cargo-management system; and up to six USB ports and six power outlets. A Blu-Ray DVD entertainment system will also be an option on the Tahoe, as will wheels sized up to 22 inches.

New functionality and technology features found on both vehicles for 2015 include:

  • Fold-flat second- and third-row seats that enhance cargo convenience – including an available power-folding feature
  • Approximately two inches greater legroom for second-row passengers, along with easier entry/exit
  • Available eight-inch color touch screen radio with next-generation MyLink connectivity
  • Up to six USB ports and six power outlets – including a 110-volt three-prong outlet – to support electronic devices of all kinds (up to 12 charging locations)
  • Available rear-seat entertainment system with dual screens (Suburban only) and Blu-ray DVD player
  • Conversation mirror in the overhead console that provides a panoramic view of the rear seats
  • Keyless entry and push-button start.

The exterior designs of the 2015 Tahoe and Suburban are more refined and precisely sculpted. Not a single exterior sheet metal panel or lighting element is shared with Chevrolet’s full-size pick-ups.

The Tahoe now benefits from the fuel-saving assistance of electric power steering, too, and its body is constructed of more high-strength steel, which GM. New inlaid doors fit into the body side openings instead of over the top of the body, significantly improving the quietness of the interior cabin and contributing to improved aerodynamics – an attribute that helps the vehicles slip through the air on the highway with less drag for greater efficiency. Lightweight aluminum hood and lift gate panels also enhance efficiency through reduced overall mass.

Projector-beam headlamps flank the Chevrolet-signature dual-port grille – chrome on all models – and sweep into the front fenders. high-intensity discharge headlamps and light-emitting diode daytime running lamps are included on the up level LTZ model.the Tahoe LTZ offers GM’s Magnetic Ride Control, which uses shocks filled with magnetically charged fluid that changes damping rates every few milliseconds. When equipped with the Magnetic Ride Control system, body control of the large SUV is remarkable, even on winding roads, while comfort is maximized.

The driving experience of the new SUVs is further enhanced with:

  • A stronger frame and a wider rear track that contributes to a more planted stance
  • LTZ models include third-generation magnetic ride control, a real-time damping system that delivers more precise body motion control by “reading” the road every millisecond and changing damping in just five milliseconds.
  • Eighteen-inch standard wheels that are a half-inch wider, reducing tire flex for improved cornering performance. Twenty- and 22-inch wheels are available.
  • New, electric variable-assist power steering system enhances fuel economy and tailors steering assist to vehicle speed.
  • New four-wheel-disc brake system with Duralife™ brake rotors that offer up to double the service life, along with brake pedal revisions that improve pedal feel for stronger-feeling, more-confident braking performance.

2015 Chevy Tahoe Engine

2015 Chevrolet Tahoe EngineThe new 5.3-liter V-8 engine in the 2015 Tahoe is strong and surprisingly efficient.

Looks can be deceiving, but in the case of the 2015 Chevy Tahoe, the looks are just the tip of the iceberg. A largely new 5.3-liter V-8 engine under the hood, backed up by a new six-speed automatic transmission, delivers marked improvement to the driving experience as well as increasing the Tahoe’s capability.

The new V-8 engine undergoes improvements in several areas, including power, efficiency, and quietness. The power upgrades boost output to 355 horsepower and 383 pound-feet of torque, while at the same time, the efficiency upgrades eke more mileage out of each gallon of gasoline.

Direct injection and cylinder deactivation are at the top of the efficiency upgrades sheet. While direct injection allows more precise and more efficient use of fuel, it does its job behind the scenes. The star of the new V-8’s efficiency cast is the cylinder deactivation mode, which allows the engine to turn off half of its cylinders under low-load conditions, effectively turning the 5.3-liter V-8 into a 2.65-liter V-4. That can yield remarkable gains in steady-state gas mileage, and the process is completely transparent to the user; there is no vibration or clunking to indicate the switch, just a little “V4” or “V8” indicator in the gauge cluster LCD display.

Beyond the improved engine, the new six-speed transmission smooths out shifts, making acceleration more seamless, and highway cruising even quieter. The combined engine and transmission team up to allow the 2015 Tahoe to tow up to 8,500 pounds as well, when properly configured.

In any case, GM’s 5.3-liter V8 engine offers lots of technology to keep it current, including direct injection and variable valve timing, which, along with active cylinder deactivation that turns this V8 into a V4 when ultimate power isn’t required, equals EPA-estimated fuel mileage ratings of 16 miles per gallon in the city and 23 highway for two-wheel-drive models (22 on the highway with four-wheel drive). Due to improved efficiencies across the entire Tahoe platform, we noticed that the 5.3-liter engine was able to operate on four cylinders much more often and for longer periods than past systems from GM, and the switch between the two modes was truly seamless. As an interesting little factoid, GM notes that its very first small-block V8 engine appeared on the scene in 1955, displacing 4.3 liters and putting out 145 hp and 238 lb-ft as an option in the ’55 Chevy Suburban.

It’s also worth noting that Chevy offers different power ratings for its 5.3 engine when run on E10 fuel and when run on E85. When filled with 85-percent ethanol, the V8 spits out 380 horses (35 more than on E10) and 416 lb-ft (33 more torques). Score one for the higher octane ratings offered by ethanol, eh? There aren’t separate fuel economy listings on the differing fuels, though, and we’d expect Tahoe drivers to lose a few mpg on E85.

Tahoe LTZ models offer Magnetic Ride Control damping, which improves comfort and stability by adjusting to match the road conditions at intervals of 5 milliseconds. Variable-assist electric power steering helps squeeze out a bit more gas mileage, but also makes steering effort light and responsive at any vehicle speed.

Chevy Tahoe Seating

Chevrolet Tahoe InsidePremium look and feel define the 2015 Tahoe’s cabin, while cargo features and comfort take a step up.The 2015 Chevy Tahoe now looks the part of an up-to-$70,000 SUV, but does it deliver on quality and feel? On comfort and convenience? It does. Improvements to the materials and overall construction come together in the 2015 Tahoe to form a much more car-like, even luxury sedan-like sense in the cabin. Supportive seats, clad in supple (optional) leather make for comfortable seating in both the front and second row (the second row gains two inches of leg room over the previous model), whether heading across town or across country. Likewise, the new cabin is whisper-quiet, further enhancing comfort on the road.

The third row of the Tahoe has been improved for 2015, but it’s still a smaller, flatter seating area that’s still best reserved for shorter adults or children and teens. Perhaps the most-improved aspect of the second- and third-row seating is the new optional power-operated folding of both rows. Buttons in the rear cargo area allow the seats to be quickly stowed to increase cargo area, and, for the third row, re-deployed into seating position just as quickly. The second-row seats still have to be manually pushed back down into seating position.

2015 Chevrolet Tahoe MPG

It’s not the greenest people-mover around, but the 2015 Tahoe takes strides toward improvement.Rated at 16 mpg city and 23 mpg highway for a combined rating of 18 mpg (in two-wheel-drive form), the 2015 Chevy Tahoe isn’t going to deliver hybrid sedan-like economy, but it is an improvement over the outgoing model.

Real-world gains may be even higher than indicated by the EPA ratings, depending on the driver’s heavy-footedness, as the cylinder deactivation system effectively transforms the Tahoe into a four-cylinder under low-load driving. In our experience behind the wheel of the Tahoe, combined scores in the low-20-mpg range are possible without resorting to hypermiling heroics.

If you add four-wheel-drive to the Tahoe’s spec list, EPA-rated gas mileage dips only slightly to 16/22 mpg city/highway, keeping the 18 mpg combined rating.

2015 Chevrolet Tahoe Price

Pricing starts from $45,980 for the 2WD LS model (including the $995 destination and delivery fee), rising to $50,995 for the LT, and $59,995 for the top-spec LTZ. Adding 4WD raises the price an even $3,000 on each trim level.
