Chevy has dropped the 4.8L engine and replaced it with a V6 with an 8 speed transmission. It delivers the same power as the 4.8L but hopefully with a bit improved fuel economy
(You can still get the 4.8L at GMC dealers; the V6 doesn't appear to be available yet)
That leaves the following engines available: 4.3L V6; Vortec® 6.0L V8 SFI engine; [size=small]2.8L Duramax® Turbo-Diesel[/size]
Take the poll and let us know what you would buy if you were forced to buy a brand new Chevy/GMC....
On the subject of swapping cogs, the six-speed automatic of yesterday is replaced by the eight-speed slushbox known as the Hydra-Matic 8L90. The two forward gears should help with fuel economy, though General Motors hasn’t released any figures yet. On the oily bits front, the 4.8-liter Vortec V8 (L20) is no longer available. The replacement is a naturally aspirated V6 (LV1 V6) that develops 265 horsepower and 295 pound-feet at 4,000 rpm.
Even though it’s 20 horsepower down on the L20 V8, the LV1 V6 produces the same torque lower in the rev range. Boasting aluminum cylinder block casting, spark ignition direct injection, and variable valve timing, the newcomer is a derivative of the 4.3-liter LV3 V6 offered in the Chevrolet Silverado and GMC Sierra. Whichever way you look at it, it’s a better, more modern plant than the L20 V8, which uses sequential fuel injection.
