The Plymouth Rapid Transit System
In car circles no other words elicit same the high energy response as “Hemi!” The highlight of the marketing of this engine in 1970 model year was Chrysler Rapid Transit System (RTS) which was made up of some of the fastest cars in class of that period. Charter members of the RTS were the renown 426 cid Hemi Cuda, the GTX fleshed out with either the 426 Hemi or 440 4 bbl, the same choice was available in the Road Runner and Sport Fury GT with the 440 cid 6 bbl Holly Carburetors, and the light Duster came armed the 340 cid blaster. About this the Plymouth marketing people wrote:
“Those of us at Plymouth who design and build high-performance cars have been inspired to go beyond just offering cars with big engines, good suspensions, great brakes, and fat tires.
We now have a system. An integrated program. . . It’s a total concept in high-performance transportation which combines the lessons learned in competition, an information network, people who understand high-performance, trick parts and great products. The Rapid Transport System is years of racing experience at Daytona, Indianapolis, Riverside. . . It’s the cars themselves, drag racing cars, Grand National stackers, rally and Championship cars. And it’s the input (and output) gained from all this racing.”
The leader of this pack was undoubtedly the Hemi Cuda. Designed by Carl Cameron, to fit any engine option Chrysler offered, the 1970 Plymouth Cuda was one of the cleanest most recognizable designs in automotive history. But all the cars of RTS looked good and ran well. Below we have the average quarter mile speed and time as registered by professional racers Sox and Martin. The handling time was registered over three laps at Willow Springs Raceway.
