The latest episode of Motor Trend’s Generation Gap pitted the two presenters against each other in finding the supreme muscle car, in what was sadly their last dip into the Ken Lingenfelter Collection.
The Buick GNX – or Grand National Experimental – features a Garrett turbocharger feeding its 3.8 liter V6, tuned by McLaren to produce 276 HP and an incredible 360 lb-ft of torque. Zero-to-sixty comes in 4.7 seconds. However, the rarer COPO Chevelle may look like the base 1969 Chevelle Malibu, but it’s set apart from that car by a behemoth 427 cubic inch V8 with a four-barrel carb, pumping out 425 HP and a seriously mental 460 lb-ft. Zero-to-sixty takes a slightly longer 5.1 seconds.
In the end, both presenters concede that the 1969 COPO Chevelle is the supreme muscle car of the two, even while Ken Lingenfelter makes an appearance to toss in a vote for the Buick GNX. Which do you prefer?
