The 1973 to 1977 Pontiac Colonnades are best known for models such as the Grand Am (1973-1975), the GTO (1973) and the Can Am (1977). However, throughout this generation of the LeMans line, with the exception of 1976, a GT option was available. While production numbers for the GT option are not available to our knowledge, 1973 to 1977 LeMans GT's seem to be hard to find today. If you have one of these unique Pontiac Colonnades, please contact us . We would love to hear from you.



The 1973 LeMans GT was available on either the LeMans coupe or LeMans Sport Coupe, the former with a large rear quarter window and bench seat only, the latter sporting a smaller, louvered rear quarter window and available bucket seats. The GT option came standard with a 3 speed heavy duty floor shift transmission, dual exhaust with chrome extensions, 14 X 7 inch Rally II wheels, G70-14 Wide Oval white lettered tires, vinyl tape GT body side stripe, GT decal on the trunk lid above the drivers side tail light, body colored outside rear view sport mirrors and wheel opening moldings. The base engine was a 350 2bbl V8. Optional were 400 cubic inch 2 bbl, 400 cubic inch 4 bbl or 455 cubic inch 4 bbl V8 engines. Also available were a 3 speed automatic or 4 speed manual transmission, Y99 handling package, NASA scooped hood, rally instrument cluster, sun roof and many other 1973 LeMans options. The 1973 GT was an attractive package and, due to its large body side stripe, even more noticeable than the 1973 GTO from a distance.

The 1974 LeMans GT option featured a slightly revised side stripe, and an added GT decal for the header panel. The package also came with blacked out grills, 14 inch Rally II wheels, G70-14 white letter tires, body colored sport mirrors and a 3.23 rear axle ratio. Available was the new Radial Tuned Suspension (RTS) package that included radial tires, specific front and rear sway bars and variable ratio power steering. The GT package could still be ordered on either the LeMans Coupe or LeMans Sport Coupe platforms, however the sport coupe could now be ordered with a formal opera window with landau style top. Most other 1974 LeMans options were available with the GT package. The engine line up was similar to 1973 with a 350 4 bbl V8 added. 3 speed automatic and 4 speed manual transmissions were again available.

The 1975 LeMans GT option came standard for the first time with the NASA scooped hood. The stripe package changed from a mid body stripe to strobe style stripes along the bottom of the fenders, doors and rear quarter panels. The package now included four GT decals (one on each front fender, one on the header panel and one on the trunk lid). The GT name was no longer integrated in to the side stripe. The package also included blacked out grills, body colored sport mirrors, and wheel opening moldings. For the first time, 15  X 7 inch Rally II wheels with GR70-15 steel belted radial white lettered tires were standard instead of 14 X 7 inch gear, because the Radial Tuned Suspension was now standard on all 75 LeMans models. The GT option could again be ordered on a base LeMans coupe or LeMans sport coupe body. The engine line up included a 250 cubic inch 1 bbl 6 cylinder, a 350 2 bbl or 350 4 bbl V8, and a 400 4 bbl V8. Only the six banger and 350 2 bbl were available with a manual transmission in 1975, and that was a column shift only affair.

The 1975 LeMans GT Canada Cup Edition

In 1975, GM of Canada introduced a special LeMans GT called the Canada Cup, available only in the Canadian market. The package looked like a US GT, but with the addition of a two-tone red and white paint scheme, with the white color covering the "ironing board" of the hood and extending across the top of the doors as well as up the A pillars to cover the roof. A landau style top was also added. The package also included a white maple leaf symbol under the GT fender decals. The package was available with either louvered rear quarter windows or the formal opera window. It is rumored that less than 50 were built though we have never seen official production figures.



The LeMans GT package took a hiatus for the 1976 model year. 



For 1977, the LeMans GT option returned on the Sport Coupe. It came standard with the handsome Grand Prix dash and instrument cluster. A two tone paint scheme was adopted with the second color covering the roof, tops of the doors, A pillars and the "ironing board" on the hood. A stylish stripe seperated the paint colors. The GT fender decal was larger than in previos years. The package could be had with the formal or louvered quarter windows. Standard features included blacked out grills, body colored sport mirrors and Rally II wheels. The RTS package was standard in all 77 LeMans models. Available engines again included those available in the rest of the LeMans line and were a catalog of GM corporate engines, with a 231 cubic inch V6 on the low end and the Pontiac 400 V8 4 bbl on the high end. In between were Pontiacs new 301 cubic inch V8, and a Pontiac 350. Even Canadian Built LeMans' were exported to the US with a 305 Chevy built V8. To add to this engine soup were the Olds built 350 and 403 V8 engines in the California market. Only the V6 was available with a manual transmission. The NASA hood was no longer available, having been retired after the 1975 model year.


1973 - 1977 LeMans GT Buyers Guide

Because the GT was an appearance option only, PHS documentation or a build sheet is essential to properly document one. While the GT option may add a small premium over the price of a similarly equipped LeMans, they generally do not bring the prices that the 1973 GTO, 1973-1975 Grand Am or 1977 Can Am models will bring in the market place. However, they will reward their owners with the satisfaction that they have a unique piece of Pontiac Colonnade history and will likely be the only one present at most car meets and shows.
