at how 87% of Dodge's volume consisted of the low-profit Dart line, compared to the upmarket Matador and Polara, of which only 41,000 were sold for the 1960 model year. As the Dart's sales climbed, Plymouth's sales dropped. Chrysler executives did little to stop the infighting between the divisions. Dart sales were so strong in 1960 that production of the medium-priced model lines were reduced. The full-size, mid-priced Matador was discontinued after the 1960 model year as buyers selected the slightly smaller but better-appointed and less expensive Dart Phoenix. The premium Polara remained in the medium-price segment in 1961. 1961 For the 1961 model year, the Dart continued as the smallest full-size Dodge. It retained the wheelbase, and was restyled to emulate the larger Polara. The same three trim levels were available: the premium Phoenix, mid-range Pioneer, and base Seneca. Once again, wagons shared the Polara's wheelbase; they also shared the Polara's unique side-mounted taillights. Engine choices included the slant-six, and the and V8s were also available in various configurations. Phoenix convertibles were equipped with V8 engines. Beginning mid-year, some Darts ordered with the 225 engine were equipped with the die-cast aluminum block. Darts in all series were equipped as standard with three-speed, column-shifted manual transmissions. Chrysler's pushbutton-shifted TorqueFlite automatic was available at extra cost. The alternator, introduced as standard equipment in 1960 on the Valiant, replaced the previous DC generator on all 1961 Chrysler products. Canadian-built 1961 Darts were identical to U.S. models on the outside, but the interior trim, controls, and displays were those used on the U.S. Plymouth. Virgil Exner's 1961 styling with its reverse fins, rear fender scalloping (the taillights were widely referred to as "ingrown toenails"), and the concave grille was highly unpopular with consumers. The low position and small size of the Dart's tail lights, just above the corners of the bumper, was also criticized and drivers of following cars complained that they could not see them. The wraparound taillights projected light sideward, not rearward. By mid-year, Dodge made auxiliary taillights available at extra cost through its dealer network. However, these large round lights were mounted near the inboard side of the reverse fins and aggravated the already awkward styling. The 1961 automobile market was generally an off-year for automobile sales, and Dodge production went down to 269,367 units, of which 142,708 were Darts. Among all the Darts sold, almost half (66,100) were the
