In the early 1970s, Inline Designs was a fledgling company making a name for itself by building high-performance racing engines for local competitions. Its success attracted the attention of two American automakers looking to make a splash at the 1973 Rally di Fruinia - Adenine Automotive and Gasril Motors.
#93 Gasril Yearling
The Inline Designs-modified Gasril Yearling followed the American tradition of stuffing a huge engine into a tiny car. The Yearling was an early American subcompact designed for cheap inline-4 engines, but Gasril offered up its 5.5L pushrod V8 from the larger Gasril Hustle and asked Inline Designs to find a way to fit it under the hood. Besides modifying the steering and suspension components to get the engine to fit, Inline Designs’s major contribution was replacing the 2-barrel carburetors with its experimental mechanical fuel injection technology. The engine, tuned for low-end grunt, produced 240hp and 338lb-ft of torque - impressive figures for a car weighing just 1120kg. 0-62 could be accomplished in 6.2 seconds. The downside? Swapping in the heavy iron-block V8 resulted in a 61/39 weight distribution.
#92 Adenine Vindicator
By comparison, the Inline Designs-modified Adenine Vindicator was unconventional in almost every way. Based on the same front-drive platform that underpinned all of Adenine’s vehicles, the Vindicator was powered by a transversely-mounted 3.5L OHC inline-6 and was known for its sleek aerodynamics and performance value. Inline Designs recast the engine block in lightweight aluminum and added its own mechanical fuel injection system. The new engine produced 169hp and 220lb-ft of torque, sending the 1033kg vehicle to 62mph in 6.7 seconds. Interestingly, the FF Vindicator matched the FR Yearling with a 61/39 weight distribution.
