Why it matters
The 911 GT1 Evolution and the 1998 GT1-98 were Porsche’s answers to the McLaren F1 GTR and Mercedes-Benz CLK GTR in GT1 racing. The GT1 was a mid-engined racing prototype that met the FIA’s homologation rules through a road-going version, and a GT1 won Le Mans in 1998 with a one-two finish.

History
The first 911 GT1 debuted at Le Mans in 1996, where the two works cars finished second and third overall and first and second in class. For 1997 Porsche introduced the GT1 Evolution with aerodynamic changes, revised suspension and the 996-style headlights, and faced the Mercedes-Benz CLK GTR. The Evo led Le Mans but dropped out in the final hours.
For 1998 development added a carbon-fibre chassis in the GT1-98, which took a one-two at Le Mans. RM Sotheby’s, citing Jürgen Barth, counts 41 GT1s in all (18 racing cars and 23 street cars).
