The General Motors New Look series (nicknamed "Fishbowl" for its round windshield) was a line of transit buses manufactured and sold in Canada and the United States. In production for over 25 years and with over 44,000 produced, it has become an iconic North American transit bus.

Flxible had their own similar model, that was also called New Look.

History

DC Transit System of Washington, DC was the first to take delivery of the New Look, taking 45 TDH-5301 buses in November 1959. GM produced the New Look at their Pontiac, Michigan facility. At the end of 1961, production of the New Look began in London, Ontario. In 1979, GM moved production from London to a new facility in Saint-Eustache, Quebec after securing an order for 1,200 buses from the province's transit agencies.

By the end of the 1960s, GM had been working on their next generation transit bus. The new RTS went into production in 1977, replacing the New Look in the United States. A revamped design of the New Look, the Classic, was introduced in 1982 for Canadian customers who weren't overly enthusiastic about the RTS. However despite the introduction of the Classic, the New Look remained in production in Canada. Some American agencies also chose to purchase the New Look and Classic. New Look production finally ended in 1986 with an order produced for Santa Monica Municipal Bus Lines of Santa Monica, California.

In production for almost 40 years, the New Look became ubiquitous in Canada and the United States. Many transit agencies also elected to keep their buses in service past their life expectancy. The Toronto Transit Commission operated a handful of New Look buses until December 2011, and Calgary Transit did the same until February 2014. As of 2015, the Société de transport de l'Outaouais in Quebec still operates one New Look in regular service. Built in 1979, it was completely restored in 2011 and is used occasionally in service.[1] In the United States, Amtran of Altoona, Pennsylvania was the last agency in the country to operate the New Look. The fleet of nine buses was officially retired in June 2018.[2]

Because of their popularity, a number of New Look buses have been preserved by individuals or museums. Many are in operating condition and go out on the occasional excursion.

Design

The New Look used a monocoque structure where the riveted aluminum body supported the weight of the bus. The engine cradle was hung off the back of the roof. This helped reduce the weight of the bus. The first model produced was 40 feet long and 102 inches wide. GM soon introduced models in lengths of 30 and 35 feet as well as a width of 96 inches.

The New Look was commonly powered by the Detroit Diesel Series 71 engine, mostly the V6 version. The engine and transmission were laid out in GM's "V-drive" configuration. The engine was mounted transversely at the rear with the transmission at an approximate 45 degree angle to the rear axle. The powertrain assembly was mounted on a cradle that could be easily removed and replaced.

The original transmission choices were a four-speed non-synchronized manual transmission and an Allison one-speed automatic transmission that transferred power through a torque converter. The two-speed Allison VS-2 with overdrive was later made available. The three-speed Allison V730 was offered beginning in 1977.

The 30 foot New Looks used a T-drive powertrain arrangement with a GMC V6 ToroFlow engine.

Models

The New Look was available in a transit or suburban version. Transit New Looks were configured for urban bus operations and generally had two doors. Suburban New Looks were configured for longer distance travel and were available with 2+2 high backed seating, parcel racks and underfloor bays and generally had one door.

The model name breaks down as follows:

  • (T)ransit or (S)uburban
  • (D)iesel or (G)asoline, later (6)-cylinder or (8)-cylinder diesel
  • (H)ydraulic (automatic) or (M)echanical (manual) transmission
  • 33 maximum seats in a 29' bus 45 maximum seats in a 35' bus, 53 maximum seats in a 40' bus

The following two digits were the model series. Odd numbers for 35' transit buses denoted a 96" width while even numbers denoted a 102" width. Odd numbers for 40' transit buses denoted a 102" width while even numbers denoted a 96" width. All 29' and suburban models were 96" wide.

Later designations included an "A" for air conditioning or "N" for non-air conditioned buses.

The serial number is sometimes listed after the model. A "C" prefix was used for buses built in London, Ontario and an "M" prefix for those built in St-Eustache, Quebec. Buses built in Pontiac, Michagan did not have any letter designation.
