It was "over the river and through the woods" for automotive journalists who recently had a chance to put the new, MY-2015 Chevrolet Tahoe and GMC Yukon Denali models to the test.

During the February ride-and-drive event, the full-size SUVs were driven in ideal highway conditions and less-than-ideal mountain roads through both rain and snowstorms. The result was highlighting the MY-2015 models' ability to handle any terrain in any weather condition.

Among the factors aiding the Chevrolet and GMC SUVs' ability to negotiate the steep grades of the ride-and-drive were the models' all-new EcoTec3 5.3L V-8 engine, which is rated at 355 hp and produces 383 lb.-ft. of torque. The engine has been EPA-rated at 16 mpg city/23 mpg highway for the 2WD models, or a nearly 10-percent increase in highway mpg and a 7-percent rise in city mpg over the previous models, according to the automaker.

The EcoTec3 5.3L is standard on the MY-2015 Chevrolet Suburban and Tahoe and the GMC Yukon and Yukon XL models. An exclusive 6.2L engine is standard on the Denali models. The 6.2L produces 420 hp and 460 lb.-ft. of torque. The 6.2L has an EPA-estimated 15 mpg city/21 highway for the 2WD model.

Regardless of engine type, both the Chevrolet and GMC SUVs come standard with a Hydra-Matic 6L80 6-speed automatic transmission.

In addition to a bold, new design in seating and suspension, both brands feature a number of safety and security features designed to protect drivers and fleet assets.

Depending on the model, both SUVs include a number of standard and available safety systems, including a standard rear-vision camera. Standard features on the LTZ trim (and available on LT trim models) include: side blind zone alert, lane change alert, and rear cross traffic alert. Standard features on the LT and LTZ models (and available on the LS models) include: forward collision alert, lane departure warning, adaptive cruise control, crash imminent braking, and a safety alert seat.

In addition to driver alert features, standard chassis control crash-avoidance technologies include GM's StabiliTrak electronic stability control with rollover mitigation technology; trailer sway control; hill-start assist; and four-wheel, four-channel anti-lock brakes. A trailer brake controller is available which sends the correct, proportional power to the trailer brakes when necessary.

Both models have a number of theft deterrent systems available, including motion detectors.

For commercial fleets, railroads and sales are the most common uses for the Tahoe and Yukon models. The largest fleet customers are law enforcement and government entities.

"We offer unique Police (9C1) and Special Services (5W4) Tahoe packages as well as a package tailored to fleet buyers (1FL). Of course we also sell LS, LT, and LTZ trims to fleets," said Dan Tigges, marketing for full-size trucks and utilities for GM Fleet and Commercial.

Why Competent Fleet Managers Are Terminated

By Mike Antich
Over the years, I have known many competent fleet managers. But, like salmons swimming upstream, not every promising fleet manager survives the challenges and rigors of day-to-day fleet management. It is understandable when fleet managers are fired for making expensive mistakes or when caught engaging in ethical transgressions, but, sadly, many more are terminated for circumstances that are entirely avoidable.
