And I am disappointed but not surprised.
engines are 2.5 4 pot 193 HP, 3.6 V6 (not the new 4.3 in the silverado) 302 HP
A diesel 4 pot will be available in 2nd year of production. 2.8 duramax same engine makes 200 HP and 370 lb-ft in over seas versions - expect it to be restricted for US emissions.
Everything goes through a 6 speed manual - JK automatic. No manual option- can't really blame GM for that one though. .
