| GM engineers put as much emphasis beneath the
Tahoe as they did inside the Tahoe. Powered by a new 5.3 liter
V8, the 2007 Tahoe produces a healthy 320 horsepower, 25 more
than the V8 in the outgoing model. Despite this additional
power, the Tahoe gets a very respectable EPA combined mileage
rating of 21.3mpg. This is accomplished in part by the better
aerodynamics, but most of the credit goes to the new
“Displacement on Demand” (DOD) feature of the new engine. This
active fuel management system shuts off four cylinders under low
or no-load conditions. |
