The Volvo 240 and 260 series were introduced in the autumn of 1974, and was initially available as six variations of the 240 Series (242L, 242DL, 244DL, 244GL, 245L and 245DL) and two variations of the 260 Series (264DL and 264GL). The 240 Series was available as a sedan (with two or four doors) or a station wagon, however, the 260 Series was available as a coupé (262C Bertone), two-door sedan, four-door sedan, or station wagon. The 200 looked much like the earlier 140 and 164, they shared the same basic body shell and were largely identical from the cowl rearward. However, the 200 incorporated many of the features and design elements tried in the Volvo VESC ESV in 1972, which was a prototype experiment in car safety. The overall safety of the driver and passengers in the event of a crash was greatly improved with very large front and rear end crumple zones. Another main change was the new engines offered, which were of an overhead cam design based on the earlier B20. The 260 series also received a V6 engine in lieu of the 164's inline-six.
