This one-of-a-kind car is perhaps the ultimate Porsche road car, ever. This is the world’s only 1998 Porsche 911 (996) GT1 ’98 Straßenversion (street version)! This lone street version, registered as BB-GT198, was modified to meet European crash, emissions, and noise standards. It features a more complete interior and tips the scales at nearly 400 pounds heavier than its track-focused sibling. Across all variations, produced a total of 41 GT1s, including 6 factory race cars, 22 Straßenversion street cars, 8 customer racing cars, 1 additional Straßenversion built in 1998, and 4 more dedicated race chassis. That same year, Porsche introduced the completely reengineered 911 GT1 ’98, constructed entirely in carbon fiber using CAD design, with just 6 race cars and the single road-going version shown here. The striking body originally sketched by Anthony Hatter was later fine-tuned in the wind tunnel by Norbert Singer, with Porsche making only minor adjustments inside and fitting a passenger seat for road use. In the 1998 FIA International GT season, the Porsche 911 GT1-98 struggled to match the pace of the improved Mercedes. At the 1998 Le Mans, Porsche’s fortunes changed as the BMW V12 LM retired with wheel bearing failure, the Mercedes CLK-LMs suffered oil pump issues in their new V8s, and the Toyota GT-One, the fastest car, encountered gearbox problems. Despite being slower, the Porsche 911 GT1-98 capitalized on its reliability, securing a 1-2 finish and Porsche’s record 16th overall Le Mans win. At Petit Le Mans in Road Atlanta, Yannick Dalmas’s 911 GT1-98 flipped backwards and crashed, similar to the flips later seen with the BMW V12 LMR in 2000 and Mercedes-Benz CLR in 1999. Across 13 events (including one test), the GT1-98 had 46 entries, 31 finishes (75% completion), one overall win, four second-place finishes, seven third-place finishes, nine total podiums, and three pole positions.
