Enter the CR-Z, whose only fault is that it has some extremely big shoes to fill. Compared to the last CR-X DX sold in the U.S., the CR-Z is 1.3 seconds quicker to 60 miles per hour (10.1 seconds for a 1991 CR-X DX, versus 8.8 seconds for a 2011 CR-Z) and returns 34 MPG combined fuel economy, 4 MPG better than the 1991 version. As for safety and comfort, it’s light years ahead of its ancestor: we barely had cell phones in 1991, let alone Bluetooth phone integration, MP3 players, electronic brake force distribution or electronic stability control. Maybe that’s the real issue: the new CR-Z isn’t a successor to the CR-X Si, but it is a suitable replacement for the CR-X DX.
