In 1968 Volvo introduced the 164 as a luxury version of their 140 series. The wings, the grille, the front bumper, the bonnet, the headlamp bezels, and the front indicators were all unique to the 164; to accommodate the long 3-litre 6-cylinder engine the 164's wings and bonnet were longer than those of the 4-cylinder 140, but the overall height and width of the 164 were the same as the 140 series. The interior featured a simulated woodgrain dashboard face and leather seating surfaces. Introduced the same year as the BMW E3, the 164 was Volvo's answer to the Mercedes-Benz 250 and Jaguar XJ6. The 164 compared favourably in terms of fuel economy with similarly sized 6-cylinder European cars such as the BMW 530.
