Standing tall, Hummer's flagship H1 Alpha model is sure to attract a large crowd. The actual owner's circle will, however, be much smaller, and may not grow significantly until Alpha H2 and H3 variations appear. Nevertheless, at the end of our test drive, we found no quarrel with GM's claims about its newest Hummer. Its off-road prowess is unmistakably excellent in open spaces and wide tracks, but its overall brawn restricts its use in smaller environments. As for on-road handling, we agree it's improved and appreciate the bump up in fuel economy and emissions.
