Old motor designations revived. The small-block V-8, dubbed the LT series, first appeared in the Corvette in 1992. It featured aluminum heads, electronic controls and a reverse-flow cooling system that cooled the heads before the rest of the engine to give it more fuel efficiency and a longer life than the older small-block V-8 versions. The LT1 generated 260 to 300 horsepower. No LT2 or LT3 engines were produced. The LT4 was GM's high-performance engine offering 330 horsepower. The 5.7-liter all-aluminum LT5 was developed for Corvette, according to Superchevy.com.

Depending on what the CTS-V gets, it may be have a different designation like the previous LSA. Hard to say what GM has up their sleeves, but if the C7 is a shorter run, then we may just see the LT1 and LT4 this round.

with the weight, blower, 8L trans etc, I'm guessing you'll see a detuned LT4 variant... LTA maybe? One thing is for sure, I will certainly be first in line. I absolutely LOVE my CTS V!

And don't forget that the LT5 designation was also used in 1978 as a "Engine Performance Pkg-High Alt."
