The Flxible Metro was a high floor transit bus sold in the United States. Grumman sold Flxible to General Automotive Coporation in 1983 who continued production of the Grumman Metro under the Flxible name.

Production of the Flxible Metro ended in 1996 after Flxible ceased operations.

Generations by letter

A letter designation is often used by transit authorities and enthusiasts to denote the different generations of the Metro. An actual model designation system is listed below.

Letter Photo Produced Description
A Early 1983 to early 1987 The Metro A retained a number of features from the 870 such as flush-mounted or sliding passenger windows and a sloped rear. Exterior changes from the 870 included a four slot grill on the front and a rear side engine grill with a cris-cross pattern. Interior changes included the Transmatic Light System in place of the Luminator system which illuminated the ad racks from behind, and stainless steel overhead standee rails in place of the molded rubber rails.
B Westchester County Bee-Line System 838-a.jpg Early 1987 to early 1992 The size of the sliding sash on the driver's window was increased. Later Metro Bs had a straight back wall instead of a sloped on to accommodate a Carrier HVAC unit.
C TriMet 1717-a.jpg 1992 The straight rear wall was made standard on the Metro C. A side control panel was added to the driver's area, thicker window frames were used for passenger windows, and there was an option for a rooftop HVAC.
D Washington Metropolitan Area Transit Authority 9830-a.jpg Early 1993 to early 1995 The Metro D featured a larger driver's area, and the the circuit breaker panel was relocated to the top portion of the drivers window.
E Elk Grove Transit 95-575-a.jpg Early 1995 to closing The Metro E was similar to the D, but the rooftop HVAC option was discontinued and a new larger rear HVAC vent was used at the rear..


Initally, model designations carried over from the Grumman Flxible 870:

Length Width Engine type Air conditioning
30 = 30 ft
35 = 35 ft
40 = 40 ft
096 = 96 in
102 = 102 in
-6 = Detroit Diesel 6V71
-8 = Detroit Diesel 8V71
-0 = No air conditioning
-1 = Air conditioning

Following the purchase of Grumman by General Automotive, model naming was revised to clearly identify the engine:

Length Width Engine type Air conditioning
30 = 30 ft
35 = 35 ft
40 = 40 ft
096 = 96 in
102 = 102 in
-4D  = Detroit Diesel Series 50
-6C  = Cummins L10
-6CG  = Cummins L10G
-6C8  = Cummins C8.3
-6CTG = Cummins C8.3G
-6M  = Cummins M11
-6N  = Detroit Diesel 6V71N
-6T  = Detroit Diesel 6V92TA
-6TL  = Detroit Diesel 6V71TA
-8  = Detroit Diesel 8V71N
-0 = No air conditioning

Flxible made some attempts to rebuild existing new look buses with a Flxible Metro body.

Southwest Ohio Regional Transit Authority 800 was rebuilt in 1983 as a ABR demonstrator. It was then sold to the Maryland Transit Administration 8381 in 1983 and following retirement returned to Southwest Ohio Regional Transit Authority. It was then sent to the Ohio Museum of Transportation for preservation.
