From Vega To Monza: A Look Back At GM’s 1970s H-Body Subcompacts

Text by Patrick Bell.

When Chevrolet introduced the subcompact Vega for model year 1971 it was an entirely new design on a new platform.  With a sporty version called the Monza in the works for MY 1975, they passed the torch to the General Motors Badge Engineering Department for further consideration.  They came up with four other names and passed them on to the other three mainline divisions.  Today we have some examples over the ten years of production of these cars that have all but disappeared from the highways and byways.

On our opening image, a brand new looking 1979 or 1980 Chevrolet Monza Sport 2+2 Hatchback that was equipped with Sport mirrors, rear spoiler, front air dam, and white-lettered tires.  There was a dealer tag on the front license plate bracket that I cannot read; perhaps someone will recognize the logo.  I have always thought this body style was a looker and it wears this shade of blue very well.

Here was the first model of the “H” body platform; the Chevrolet Vega that was introduced for the 1971 model year.  This one was a Hatchback Coupe from the 1971-1973 era, and it was a basic edition with an aftermarket side stripe.

This gentleman seems pleased with his 1978 Pontiac Sunbird Sport Coupe with a New Jersey license plate.  It also had the Landau style vinyl roof and a driver’s side sport mirror.  The pinstripe and body side moldings both look aftermarket.

1977 was the last year for the Vega, so in 1978 Chevrolet expanded the Monza line and added a less expensive hatchback with the Towne Coupe’s front and rear body treatment along with a wagon.  This 1978-1980 2+2 Hatchback may have been new with a buyers tag in the quarter window.  It had the optional body side molding, wheel opening trim, and color keyed Deluxe wheel covers. The Vega engine went out with the Vega, so the 151 cubic inch “Iron Duke” 4 cylinder was now standard, with 2 V6’s and the 305 V8 optional.

Pontiac rebadged the Vega and introduced it as the Astre in Canada for the 1973 model year.  In 1975 in came to the USA, and was produced through 1977. This one is a Canadian 1974 GT Hatchback.  In the background was a white Ventura 2 door and a brown full size 4 door sedan, likely a Catalina or Laurentian.  The featured dealership also carried Buicks.

In with the new and out with the old.  The back lot of dealerships are a fun place to explore and they can hold some constrasts.  In the center a 1978 or 1979 Monza 2+2 Sport Hatchback Coupe with the Spyder Appearance Package.  It could have been a trade in or a customer’s car waiting on parts or service.

To the left was one of three Chevettes along the fence line.  This one was a 1975-1978 model, but it looked new with no license plate and no dirt behind it.  On the right was a new red Citation 2-door Hatchback Coupe.  The Citation was introduced in April of 1979 as an 1980 model, so perhaps the Chevette was a leftover and the Citation was a very early one.

This one was a 1975-1977 Monza 2+2 Hatchback Coupe from Michigan with an aftermarket stripe, wider wheels and tires, and rear mudguards.  The 1975 was available with a 2.3 liter 4 cylinder motor borrowed from the Vega, as well as a 4.3 liter V8, except in California where the 5.7 V8 was used. Transmission choices included 3, 4, and 5-speed manuals along with the Turbo Hydra-Matic, though all transmissions were not available with all engines.

Buick’s version was the Skyhawk, and they only had the Hatchback Coupe body style and used their own 3.8 liter V6 for the sole engine offering.  It was in production from 1975-1980.  This one was a 1977 model, and had the one year only NightHawk package, which was an appearance option.  Available only on black cars, the decals apparently were gold when light was shown on them.  The Skyhawk sold the least amount of cars in the six years with Oldsmobile Starfire a close second.  Their total sales together amounted to about 66% of the Monza hatchback only sales for the same period.

A 1978-1980 Monza Coupe with Sport Mirrors and Rally II Wheels was posing in the driveway.  The rear spoiler and lower body two tone may have been aftermarket as I see no such options in the sales brochures.  It could have been a dealer installed package.

Posing in the middle of a cul-de-sac was a 1974 or 1975 Vega GT Hatchback with the Sport Stripes, which were a separate option with the GT package.  In the background was a pale yellow 1969 Chrysler Newport 2 door hardtop.

The photo notes state this was the photographer’s new 1978 Buick Skyhawk along with their 4 year old (1974) Pontiac Grand Safari wagon.  The Skyhawk was equipped with the optional Deluxe Wheel Covers and the Appearance Group, which consisted of a left side Sport Mirror and wheel opening moldings.  It was available with your choice of 4 or 5-speed manual or automatic transmission.

The Monza Towne Coupe was the formal edition, and this one represents the 1975-1977 style.  It had the full vinyl roof and a license plate I can’t read.

Parked on the left was a 1974 or 1975 Ford Maverick, and otherwise Chevrolet Chevelles ruled the parking lot.  In the lower right was the left taillight of a 1964, further up a red 1969, and in the center a dark blue 1966 Malibu Sport Coupe.

Since the Astre went away after 1977, like Chevrolet, Pontiac expanded the Sunbird line for 1978 and called this model the Sport Hatch.  This one was a 1978-1980 model, had the Custom Wheel Covers, likely an aftermarket stripe, and some minor body damage on the front corner.  By now the 2.5 liter “Iron Duke” 4 cylinder was standard with a 3.8 liter V6 optional, with 4 and 5-speed manuals and an automatic for transmissions.  In the background was an 1983 or 1984 Oldsmobile Delta 88 Royale Coupe.

The photo notes indicate this Sunbird Coupe from Texas was a 1980 model, and was dressed up with aftermarket pinstripes and wheels.  On the other side of it looks like an 1980-1985 Buick Skylark sedan.  The lady and baby girl appear to be enjoying the sunny day.

A final year 1980 Monza Sport 2+2 Hatchback Coupe with the Spyder Equipment Package, which did include some suspension upgrades along with the appearance items such as a lot of black out trim that does not show on this black car.  Engine and transmission choices were both down to two; the “Iron Duke” 4 cylinder and 3.8 V6, and 4-speed manual and automatic.  It is interesting they dropped the 5-speed.

And another Monza Sport 2+2 Hatchback Coupe, this one a 1978 model with both the Spyder Equipment Package and the Spyder Appearance Package, as well as one of the optional motors and a damaged front lower air dam.

This one was a final year 1980 Sunbird Sport Hatch with the optional Formula Package and Removable Sunroof.  The Formula Package included upgraded wheels and tires (which were replaced with aftermarket on this one), a Rally Gage Cluster, otherwise it was all appearance items.  The engine/transmissions choices were down to the same two as the Monza.  The blue car on the right edge was a 1972 Plymouth Satellite Sebring or Sebring Plus.

We have one Oldsmobile Starfire, which like Buick only had the hatchback body style.  This tired one was a 1979 model, and had the optional Firenza Package.  There were three engines and transmissions available for this year; “Iron Duke” 4 cylinder, 3.8 V6, and 5.0 V8, along with 4 and 5-speed manuals and a 3-speed automatic.  The image was dated 1990, and notes indicated it was a 4 cylinder model and on its way to the junk yard.

To close we have one more 1980 Sunbird Formula Sport Hatch, this one in silver with the Removeable Sunroof and the sharp looking Cast Aluminum Wheels, plus an aftermarket louver for the back window.

Thanks for joining us and have a great day!
