Our 5,095-pound test car weighed in 313 pounds lighter than the original, and it laid down an impressive 4.0-second run to 60 mph en route to a 12.6-second, 109.1-mph quarter mile.

Mother Nature laid it on thick: rain, wind, even a little ice for my test drive of the redesigned GS 430. Would this debutant handle the big stuff and still keep its luxe cool?
