GM bests Ford's EcoBoost V6 fuel efficiency without complex, expensive turbochargers
Ford has spent a great deal of time and money developing and marketing its EcoBoost family. The company makes a wide variety of EcoBoost engines (which is basically a fancy name for turbocharging plus direct injection) ranging from a
Ford's efforts have paid off, as sales of the naturally aspirated V6- and EcoBoost V6-equipped F-150s have
outpaced those of the V8 models
. And all along the way, Ford has thumbed its nose at the Chevrolet Silverado/GMC Sierra, stating how its EcoBoost V6 gets V8 performance and V6 fuel economy.
GM, however, is hitting back today with the announcement that its new 5.3-liter EcoTec3 V8 engines manages to produce 355 horsepower and 383 lb-ft of torque. While the horsepower number compares favorably with the EcoBoost V6 in the F-150, it's down quite a bit in torque. GM says that in 4x2 trim, the EcoTec3 will be good for 23 mpg highway; checking off the 4x4 option box will result in 22 mpg on the highway.

Both of these numbers are 1 mpg better than the EcoBoost F-150. In fact, it matches the fuel economy of Ford’s naturally aspirated, 3.7-liter V6.
“Silverado’s available 5.3-liter EcoTec3 V8 gives customers the best of both worlds,” bragged Jeff Luke, executive chief engineer for the Silverado. “Customers get the proven power and dependability of a V-8 truck engine, with better fuel economy than a leading competitor’s smaller turbocharged V-6.”

GM's decision to go the "tried and true" route may pay off in the end. Recent reports have suggested that while many manufacturers seem to ace the EPA's tests with turbocharged gasoline engines,
most consumers aren't able to match the sticker numbers in the real world

GM’s fun in the mpg sun, however, likely won’t last long. Ford is reportedly
looking to trim up to 700 pounds
from the next generation F-150, which will go a long way towards improving fuel efficiency. Ford showcased the use of active aero technology on its
Atlas truck concept
(which no doubt is a precursor to the next generation F-150), which boost highway fuel efficiency by 2 mpg.

The current Kia SUV does just that, either is sluggish or out of control.
Read about it at C&D.

It's all in how the turbo is sized and tuned. Lot's of truck use turbos where the boost comes on early in the RPM range and with little lag. As a general rule you don't make max HP with such a setup. Cars aiming to have some sporting credentials may use a system that's intended to maximize power which means you've got to have exhaust flow which in turn means RPMs and WOT. Add in a large turbo (which takes time to spin up) and you've got the sudden-surge-of-power when-I-didn't-expect-it "problem".
cars today lean towards the less boost, wide torque band side of things than cars of yesteryear did. My 93 MR2 leaned more towards the peakier, max power side.
