In January 1956, the Metro was updated with Austin's 1500-cc A50 engine. A higher 8.3:1 compression resulted in an increase in horsepower, now rated at 52. A larger clutch was also fitted. Also new was the hood, a mesh grille, and stainless-steel side strips which separated the two-tone body colors. The interior was updated as well, with a black dashboard replacing the former body-colored dashboard. In 1957, the names of Nash Metropolitan and Hudson Metropolitan were no longer used, as the Metro became its own model.
The Austin Motor Company acquired the rights to sell the Metropolitan to non-North American markets in December of 1956. Modifications to the interior and engine compartment allowed both left and right hand drive models to be made.
Several more improvements were seen for 1959, including a glove box door, seat adjusters, and window vents. Mid-year models had an opening trunk lid and tubeless tires, with sales peaking this year with 22,309 cars sold. The last Metropolitan's were fitted with the 55-horsepower A55 Austin engine. Although production stopped in 1960, 'leftovers' were sold for another two years.(http://www.classic-car-history.com/nash-metropolitan.htm)
