Various upgrade packages were offered by Motion Industries, for the Chevrolet models included within the Baldwin Corvette partnership. The most prominent of these packages included the SS (425 HP) and Phase III (500+ HP) offerings. These cars not only came with a performance promise, but a guarantee to back it up. All Phase III cars came with a personal guarantee.
The Chevrolet Aerovette (originally designated Experimental Project XP-882) was developed in the late 1960's under the watchful eyes and mind of Zora Arkus-Duntov.
