1969 Mercury Cougar not fast enough for 1970 Buick GSX in Classic Drag Race
The package transformed the Cougar into a sportier coupe by adding a rear spoiler, front spoiler, engine hood scoop and side stripes. It also added bucket seats inside the cabin and some unique touches to the dashboard.
The 7.0-liter Cobra Jet V8 was the most powerful mill offered by Mercury on the Cougar in 1969. It produced 335 horsepower and 440 lb-ft (597 Nm) of torque. In this car, it shifts to the rear wheels through a three-speed automatic transmission.
In this classic drag race, the Cougar faces off against a 1970 Buick GSX. A more capable version of the Gran Sport nameplate, the GSX was slightly larger than the Cougar, but it had plenty of horsepower to boot. This Stage 1 model came with a 7.5-liter V8 developing 360 horsepower and 510 lb-ft (691 Nm) of torque under the hood.
It’s a bit heavier than the Cougar, but the GSX was also slightly heavier. Like the Mercury, this Buick is equipped with a three-speed automatic transmission.
As the datasheets suggest, it’s a close battle. The GSX rider takes full advantage of the extra horsepower and torque and gains the quarter mile by almost half a second. The Buick takes the flag in 13.47 seconds at 102.29 mph (164.61 km / h), followed by the Cougar in 13.92 clicks at 98.83 mph (159.05 km / h).
Stage two sees the Cougar off to a better start, so it crosses the finish line first in 13.86 seconds at 99.22 mph (159.67 km / h). The GSX came in second, but had the best ET at 13.76 clicks, to go with a trap speed of 102.34 mph (164.70 km / h).
The third round is very similar to the first. The GSX moved forward and took the win with an ET of 13.56 seconds at 162.89 km / h. The Cougar arrives at the finish line after 13.9 seconds, accelerating to 98.94 mph (159.22 km / h).
The GSX was actually knocked out of this round because it ran faster than its qualifying benchmark, so the Cougar was declared the winner, but it’s pretty obvious the Buick is the faster of the two. I would always take the Cougar on the GSX any day of the week for its unique look.
