Cruiser was also the final Oldsmobile produced only with a 3-passenger front bench seat; all subsequent vehicles produced by the division were sold with 2-passenger front seating as standard or as an option. In place of the Custom Cruiser, Oldsmobile concentrated on the marketing of the Bravada SUV and Silhouette minivan. Until its 1996 discontinuation, the Buick Roadmaster Estate was marketed as a functional replacement for the Custom Cruiser (as Buick would not market a minivan or SUV under its own brand until after the closure of Oldsmobile). Chassis The 1991 and 1992 Oldsmobile Custom Cruiser is based upon the GM B platform. Sharing its wheelbase with the 1977-1990 B-platform, the third-generation Custom Cruiser and its counterparts are largely re-bodied versions of their predecessors. Primarily through the addition of additional safety equipment, the redesign of the Custom Cruiser added nearly 100 pounds of weight to the vehicle (though nearly 650 pounds lighter than a 1976 counterpart). Following the 1992 discontinuation of the Custom Cruiser, the Buick Roadmaster Estate and Chevrolet Caprice Estate were produced with no major changes (to the B-body platform) through their 1996 discontinuation, outside of the 1994 replacement of the L05 V8 with the LT1 V8 for 1994. Powertrain As part of the redesign of the GM B platform for 1991, General Motors retired divisionally-produced engines (in favor of the Chevrolet small-block V8) for the B platform. The long-running Oldsmobile 307 was replaced by a 170hp 5.0 L V8 (a 30hp increase); in a first for a rear-wheel drive Oldsmobile, the V8 was fuel-injected. For 1992, a 180hp 5.7 L V8 was introduced as an option. Both engines were paired with the Hydramatic 4L60 4-speed overdrive automatic (replacing the THM200-4R). Body As with the previous generation, the Custom Cruiser shared nearly its entire body with its Chevrolet and Buick counterparts, sharing design features from both model lines. The use of chrome was reduced, with plastic-covered 5-mph bumpers replacing the previous steel bumpers. Shared with the Buick Roadmaster Estate, the Custom Cruiser was fitted with a fixed second-row skylight allowing for a slightly raised rear roofline (similar to the Vista Cruiser); the body-color split grille derived much of its design from the Chevrolet Caprice. To distinguish the Custom Cruiser from its Buick and Chevrolet counterparts, the model line was fitted with standard two-tone paint; alloy wheels were offered as an option. In contrast to the Roadmaster Estate, the
