Pontiac redesigned its front-drive full-size sedan for 2000, again similar to the Buick LeSabre, with fresh styling but carryover powertrains. Wheelbase and overall length increased by nearly two inches, but head room shrunk slightly and interior leg room was unchanged. Side-impact airbags for front seats were newly standard. GM's StabiliTrak antiskid system was installed in the top-line SSEi model, designed to selectively brake the front wheels to counteract skids in turns. The lineup also included SE and midrange SLE sedans. All Bonnevilles had standard front bucket seats, but the SE offers an optional bench for 6-passenger capacity. Only a 3.8-liter V6 was available, as before, in two ratings. For SE and SLE models, the V6 produced 205 horsepower. In the SSEi, a supercharged version delivered 240 bhp. Both engines were hooked to a four-speed automatic transmission. Traction control was standard on the SSEi and optional on others. Antilock all-disc brakes replaced the previous disc/drum setup, and a tire-inflation monitor became standard. GM's EyeCue head-up display, which projects primary instrument readings onto the windshield, was standard in the SSEi.
