The Forward Look designs were now replaced with a square side styling. A 413 CID V8 engine was optional in the 1965 model year. The New Yorker had dual exhaust pipes, and power brakes, steering all optional too. The 440 Firepower was phased for the next model year, the engine produced 375 horsepower. The 440 CID V-8 engine was adopted in 1966 in the New Yorker. A new grille was introduced, taillamps and a reviewed side trim were the changes made for 1966. The Town and Country wagon was dropped as a model and marketed as a series on its own. This was a successful year for Chrysler limited both in the output production and units sold.
A metal redesign was introduced under the beltline with wraparound parking lights at the front and taillights at the back on the 1957 New Yorker. To replace the straight look of 1965-66, a fast top design was created for the two-door hardtop. The four-door sedan adopted the four window style used on the Newport sedan and was previously dropped. This year the economic state performed poorly affecting the sales for 1967, sales dropped by 20% and were recorded as the least for the past five years.
For the 1968 model year, the New Yorker gained new rear and front fender highlights. The New Yorker retained the original roofline debuted in 1965, while the Newport and 300 series four-door hardtops gained a new sporty-roofline shared with the Plymouth and Dodge. Chrysler’s large C-bodies were greatly worked on obtaining curved sides and a higher beltline. The new-look was called ‘Fuselage styling’ and was not well welcomed as the 1968 models. The two-door hardtops had a look similar to the 1940s club coupes.
For 1970, a few changes were made to the grille, taillamps, and trim area. The tiny windows on the front doors were dropped on the two-door hardtops. The sales for the next year were predicted to be low and the facelift scheduled for that year was carried forward to the next year. There were very few updates in styling for this year.
