Overview & Reviews

The discontinued Chevrolet Tahoe Hybrid came close to being a best-of-both-worlds sort of vehicle. To wit, it seats eight, can tow 6,200 pounds when properly equipped and gets up to 21 mpg in mixed driving. Unfortunately, the Tahoe Hybrid was considerably more expensive than a regular Tahoe when new, making it a questionable purchase from a value standpoint. And just like the regular Tahoe, the Hybrid suffered from some inherent shortcomings that made a large crossover SUV a better choice for many shoppers.

The Tahoe Hybrid never sold particularly well, so finding a used one could prove challenging. If you do track one down, keep in mind that similarly priced three-row crossovers are likely to provide comparable fuel economy and a better driving experience. Note, too, that the hybrid power system is quite complex, so long-term reliability is a bigger question mark than usual. But if you're looking for big-SUV functionality in a relatively fuel-efficient package, a used Tahoe Hybrid could still fill the bill.

Used Chevrolet Tahoe Hybrid Models
Produced in a single generation for the 2008-'13 model years, the Chevrolet Tahoe Hybrid is a full-size SUV with a gasoline/electric powertrain that produces a healthy 379 horsepower. EPA fuel economy ratings fluctuated slightly through the years, but the combined city/highway figure was consistently 21 mpg for the rear-wheel-drive Tahoe Hybrid, with the four-wheel-drive version hovering between 20 and 21 mpg. At the time, this was approximately 30 percent better than the regular Tahoe could manage.

The secret lies in the interplay between the twin electric motors and the 6.0-liter gasoline V8 engine. For one thing, the Tahoe Hybrid can accelerate from a standstill to about 30 mph on electricity alone, though you'll need flat (or ideally downward-sloping) ground and very patient drivers behind you to make it happen. But even when the gasoline engine kicks in, the electric motors minimize fuel consumption by continuing to provide motivation. The Tahoe also capitalizes on familiar hybrid technologies such as regenerative brakes, which are used to recharge the battery pack while slowing the vehicle.

GM developed this hybrid system in conjunction with BMW and the now-defunct DaimlerChrysler partnership. The most novel component is the transmission, which uses three special planetary gearsets in addition to four fixed ratios like a conventional automatic. Depending on the driving situation, this electronically variable transmission (EVT) can function with continuously variable gearing for light loads or fixed-ratio strength for heavy-duty tasks.

Because of the considerable weight added by the hybrid-related components, Chevrolet made an effort to lighten the load and streamline the Tahoe Hybrid. Some of the body panels are made of aluminum, while thin-profile seats shed additional pounds. The Tahoe Hybrid also has aerodynamic add-ons and low-rolling-resistance tires. It's a bit surprising, then, that the four-wheel-drive Hybrid has low-range gearing, an unusual attribute for a hybrid SUV.

The rest of the Chevy Tahoe Hybrid is largely identical to well-equipped regular Tahoe models of the same vintage. It has three rows of seating, an eight-passenger capacity and up to 109 cubic feet of cargo space, more than any other hybrid. To access that full space, however, you have to physically remove the third row of seats -- just about every other large SUV allows you to fold it flat into the floor. Standard features included leather seating, a premium sound system and a navigation system. The only significant items left as options were a rear-seat entertainment system and a sunroof.

In reviews of the Chevrolet Tahoe Hybrid, we found that it drove very much like a regular Tahoe from that era. In fact, its acceleration and highway passing performance were a shade better. But while the Hybrid's combined fuel economy rating was a major improvement, it's still a far cry from what most people would consider "good" in the absolute sense. Overall, consumers who don't need massive towing capacity would be better served by equally roomy crossovers like the three-row Chevrolet Traverse.

Changes were few and far between for the Tahoe Hybrid. For 2009, power-adjustable pedals became standard, while the 2012 model added front-seat side airbags. Otherwise, this quirky truck received only minor technology upgrades during its run.

  Wasnt what I thought it would be. - 2008 Chevrolet Tahoe Hybrid
  By Carlos - May 22 - 5:31 am

  There are a bunch of other problems that you get with this purchase. First, you lose a lot of standard features that come on cheaper models of this vehicle. Convenience features like automatic lift gate and luggage rack, and safety features like a spare tire and jack. Also, if you get a bad hybrid generator (battery pack) like I did youre screwed. I tried several times to have it replaced while it was under warranty and GM came up with all types of excuses why it wasnt the battery pack. But once the warranty went out they said that the new battery pack would be about $5k. The battery pack controls EVERYTHING.. When it goes everything will run intermittently. And they will gradually die off at a very high expense to safety. For example: The computer that controls the interchange between gas and electric motors will cut the car off when you try to go after stops for lifts or signs. So you will cut off intersections and sometimes in slow or stop-no-go traffic. Mine has cut off thing to cross intersections with vehicles coming. I have to hold down the brake and rev the gas (Almost like in a manual transmission) to keep it from going to electric to avoid this. Which defeats the purpose of the hybrid because you still burn the extra fuel. Its just not worth it.

  Honest Review, 2008 Tahoe Hybrid, Owned 5 yrs - 2008 Chevrolet Tahoe Hybrid
  By Thomas - February 28 - 7:56 pm

  2008 Tahoe Hybrid, birch metallic. Just sold it after 5 yrs ownership, bitter sweet ... Honestly, I bought this big truck for its looks. And because I have 3 kids so I needed something bigger. Im also a car guy so I just cant spend $30 or $40 k and have to look at a minivan in my driveway. Im a man, so I do like to mow the lawn, wash the truck, and have a beer in the yard and admire both. This truck allowed me to check that box. The magnesium alloy 18" wheels are beautiful and the box shape was so anti-minivan I just had to have it. The Tahoe had a legendary reputation. I also found my Hybrid model at a dealer off trade in for $35K with only 12K miles on it. Made the decision easy. Good : The looks. If you dont like the boxy GMT900 style, dont get it. Its the single most appealing feature. Its exterior far outshines the bland, big Pilot looking Expedition. The Durango in that time frame looked like it was built in the early 1900s. Nothing from the Germans came anywhere close for the price (or features). The looks of this vehicle sells it (and all those cheesy Hybrid decals come off easily using a hair dryer). The ride was also great, I was dumbfounded as to how a body on frame vehicle could cruise at 85 mpg as if it were an Audi. Very impressive body dampening. Engine reliability was perfect for 90k miles. And the 6L V8 with electric motors assisting would really rocket this vehicle to dangerous speeds. Good thing it was limited to 96 mph, I often found myself hitting that limiter as the truck felt like it was good for much much more. Now with the good comes the bad. This is a heavy, dumb, clumsy, body on frame truck. Make no mistake about that. You are sacrificing vastly superior minivan and unibody drivability and mall parking lot maneuverability in big sums to own this truck. Its 39 turning radius is abysmal. Ingress/egress is also more difficult because it rides higher up. The 2wd model I owned was LESS capable off road than a Yugo GVX. It seemed like 90% of the weight rode on the front axle, and they drive the rear wheels. Dont take the 2wd version even into a dry lawn. OK what else ... the transmission had a "clunkiness" that just got to my nerves eventually. It would sometimes get confused between hybrid mode, 4 cylinder, and 8 cylinder modes. This would result in driveline shutters and clunks that just should not of been there in a vehicle costing $55k new. The rear diff was replaced under extended warranty at 80K miles. The entire rear diff, all the gears, bearings, bushings, everything. I never towed anything. You have of course read about the infamous cracked dash issues. I wont go into that, but mine was nearly cracked in 2. All the door locks failed repeatedly. Thankfully we found GruvenParts.com making the reliable replacements, never had a problem since. The Nav and OnStar, while it all functioned fine, was far behind the times (and still is). I miss the truck, mainly for its stunner looks. Sadly its reliablity and driveability left so much to be desired. I wonder if the 2015 model is better, I still see they use a live rear axle. I hope they didnt just reshape the sheet metal and slap a $70K sticker price on it. If they did, GM has no merit to receive another bail out. Cmon guys you can do far better... I would not buy another GM, ever. Mainly due to the repeated interactions with GM customer service on the dash and door locks. They have hired off shore contractors to hire customer service who know nothing and care nothing about the US owners. With the dash, they directed me to a local dealer, then told me it was entirely up to them. I sat down with the service manager and he said why the heck is it my problem ? I agreed. The dash is flawed, GM should cover it, not give owners of $55K trucks a circle jerk. I will not buy another because of this. Sorry.
