BMW’s 645Ci entered the 6 Series range for 2004 to 2004 in this dataset, represented by 4 verified tests spanning that single model year. In E63/E64 form, its performance identity centered on the 325-hp N62B44 naturally aspirated V8 and a gasoline-only layout. The earliest benchmark also remained the quickest: the 2004 Coupe (Sport) set the model’s best 0-60 time at 5.3 seconds and covered the quarter-mile in 13.9 seconds at 102 mph. That established the upper end of a narrow one-year range.
