 The later R1 Japanese-market micro shared the styling and chassis with the R1e and was exhibited as a prototype at the 2004 Tokyo Motor Show, one year after the R1e concept.The R1 adopted a "one-motion form" with "a flowing eggshell shape" that "effectively absorb[ed] crash impact".It was styled with the same grille as the 1st generation B9 Tribeca, which had been introduced earlier in 2003 as a signature corporate look on the B11S concept vehicle.
