THE 2012 Chevrolet Camaro ZL1 has a heavy load to bear. Its model designation, borrowing the General Motors option code for one of the most storied V-8 engines of the muscle car’s glory days, sets lofty expectations among those who lived through Detroit’s horsepower wars.
In truth, by the time the original ZL1 engine arrived in a limited run of bare-bones Camaro coupes for the 1969 model year, the muscle car craze was already doomed. Still, the car was remarkable: what looked like a 6-cylinder brown bag from the outside, with nothing, save for the bulge of its cold-air ZL2 hood, to give it away, was actually powered by an all-aluminum brute rumored to produce as much as 500 horsepower.
