The crew from Electric Federal recently sat down with Dick Guldstrand to discuss the builder's favorite creation. Guldstrand grew up during the glory days of the California hot rod scene and made a name for himself racing and building Chevrolet Corvette bruisers. In the early '90s, he became dismayed at rumors that General Motors was considering cancelling the sports car. In order to stoke a little excitement, Guldstrand picked up a 475-horsepower Corvette ZR-1 and let designer Steve Winter loose on the car. The result became the short-lived 1994 Guldstrand Corvette GS90 Coupe.

While the car retained its factory side glass, windshield and rearview mirrors, nearly every other exterior body panel received significant tweaking. Guldstrand also fitted the car with beefier anti-roll bars and coil-over suspension at all four corners. Combined with larger wheels and tires, the GS90 is said to have handled substantially better than the ZR-1 on which it was based. Of course, the cars were also pricey at $206,208 apiece. Guldstrand only sold six, but that clearly hasn't dampened his enthusiasm for his creation. Check out the Electric Federal video essay on the builder and his GS90 below.

      Pretty cool car, the rear is a little crazy but I like it.

      Holy nostalgia, I remember seeing this car in magazines when I was in grade school but completely forgot about it afterwards (I probably just remembered it as a Shelby Series 1). Never remembered it being based off a Corvette, but it makes sense thinking about it. Cool car, shame he only sold 6.

      What a brilliant design! Look at the design cuse of that car (from 1994 !) and than look at a c6. Unbeliveable, the lights, front grill, the door handles, the over all flow of the body. Its liek this guy was 20 years ahead of GM.

      If you look at some pics of the car (the video is insufficient) you'll see that the car is pretty ridiculous. https://www.google.com/search?q=1994+Guldstrand+Corvette+GS90+Coupe&safe=off&tbm=isch&tbo=u&source=univ&sa=X&ei=QHanUdecIuLkygGkhYCIAQ&ved=0CDsQsAQ&biw=1382&bih=894

      is it bad that the first thing I though of when they do the close ups of the glove box is how shitty GM's plastic interiors was in the early 90's????

        It wasn't just the 90's. It was the 80's, 90's, and well into the 2000's.

      The beauty of the GS90 was that it ahead of its time in promising max horsepower from natural gas--talk about being ahead of the curve, like by about 20 years

      \"Didn\'t change the interior\" !!! That\'s the first thing I would have chosen to can on the early 90\'s C4/ZR1\'s. Had a ZR1 of that ilk...\"baby diarrhea\" yellow leather seats padded like playroom chairs, plastic trim that couldn\'t keep it\'s own colored surface for more than a year and so soft, scratches appeared daily. Nice engine though..if you didn\'t mind the drone at highway speeds....

      Loved the C4s. I especially liked the little beer cooler they installed behind the seats.

      I vaguely remember that from articles at the time - still a very cool car. Did you mean to say "he picked up a 405-horsepower Corvette ZR-1"?

        I think the cars had engine mods done by an outside source, and began conversion with 475.
