AutoWeek / Automotive News has an interesting article about the new top 3.6l VVT V-6 that will see duty in the 08 CTS (as well as the STS and likely the SRX at some point).
An interesting tidbit is that this is the most powerful V-6 GM has ever built (even including the fire-breathing, turbo-charged monster that was in the Buick GNX). The secret is the use of direct injection technology (where fuel is injected directly into the combustion chamber at ultra-high pressure right when it is needed).
Even better is how this engine produces the extra power with improved emissions and fuel economy as well.
