The following comes to us from Gary K.:
I have owned 7 Suburbans since 1985. All have been greatly improved by the next generation. I am a diehard Chevy guy and I currently drive a 2008 LTZ 1500 with a 6.0. My next purchase will only be a Suburban if GM gives me the option of the new 8-speed and the 6.2-liter EcoTec.
Otherwise, I may be heading to the Big Blue Oval. A Suburban should be offered with engine options to suit the customer. GMC has always done it! Now, is Suburban going to get the 8-speed and the bigger 6.2?
Gary, we completely agree with you on this: GM should offer the 6.2L V8 L86 and 8-speed automatic transmission in the Suburban (and Tahoe), especially given that:
- The increased prices of the twelfth-generation, 2015+ Suburban (and 2015+ Tahoe), and
- The GMC Yukon and Yukon XL offer the 6.2-liter EcoTec3 V8 alongside the 5.3-liter EcoTec3 V8
Alas, GM seems to be perfectly content with artificially limiting the Tahoe and Suburban because they are Chevrolets and hence are not part of a “premium” brand (as if GMC were really “premium”, but we digress for now). What GM seems to not understand is that there are potential customers (such as yourself) who don’t want a GMC, either because of the brand (they are loyal to Chevy) or because of the styling (they like the styling the Tahoe/Suburban). This problem is exacerbated when we consider the Fact that Ford doesn’t limit the Expedition in the way GM limits Chevrolet.
So, we wish GM would stop artificially propping up GMC at the expense of Chevy by not offering obviously-desired high-end features, even as options. And we will join you in yelling from the rooftops for GM to add the 6.2L V8 L86 as an option to the full-size Tahoe and Suburban. Mate it to the 8-speed 8L90 transmission, and call it a day.
Update: we have just asked if GM should offer the 6.2L V8 in the Tahoe and Suburban. Vote here.
