The changes made to the 1964 Studebaker Avanti were mainly just interior updates. The car had proven to be very speedy
on the road especially those with a Paxton supercharger. Andy Granatelli put the car through its paces and felt it was
indeed one of the faster cars in the 60's. The R1 engine contributed 240 HP and the R2 was around 300 HP and with the light
weight fiberglass body, the car was capable of speeds over 160 mph.
Studebaker had R3 and R4 versions and experimented with an R5 version with around 575 HP. The R5 had dual superchargers, fuel
injection with magneto ignition. These engines were in limited supply and, as far as it is known, none really reached the public.
Unfortunately, the company producing the fiberglass bodies had manufacturing problems because
of a strike and Studebaker had to set up their South Bend plant to produce the bodies but without much success. Orders that were
taken earlier ended up being canceled by customers who switched to cars such as the Chevrolet Corvette.
The Studebaker Avanti had a lot of appeal but because of various problems did not sell in the numbers predicted. The company
had updated the versions of the Lark, Hawk, Avanti, and even brought out a new Lark model called the Wagonaire but it was
not enough to make the automotive division into a profitable business.
