The YouTube channel Out of Spec Renew just lately met up with the Basic EV Conversion staff close to Denver, CO to take a look at their 1980’s Pontiac Fiero GT conversion. The auto store focuses on preserving the character of basic vehicles whereas electrifying them for the trendy age. This well-executed Fiero GT conversion is the one which put them on the map.
The Pontiac Fiero is powered by the battery pack and twin motor drive unit from a wrecked 2014 Tesla Mannequin S. The pack was break up into two segments, with a smaller pack positioned beneath the hood and the bigger pack moved to the trunk, however there’s nonetheless some trunk storage remaining. The low-voltage parts and high-voltage wiring run by means of the middle of the automobile the place a transmission tunnel would usually be situated. Though on the mid-engine Fiero, that is the place the fuel tank was initially housed.
Whereas they haven’t had the chance to check the Tesla-powered Fiero on a dynamometer but, they estimate it outputs between 350 and 400 hp and about 400 lb-ft of torque. This can be a huge enhance from the highest-powered Fiero GT of the day, which output 140 hp and 170 lb-ft of torque.
After its launch in 1984, the Fiero was a surprisingly huge hit and obtained a number of updates over the subsequent few years. However by 1987, the unique 1984 items had been starting to catch hearth at an astonishing price on account of not one however a number of faults together with the engine, oil pan, and wiring. Tons of of Fieros caught hearth in only a few years, one of many highest failure charges ever seen for a mass-production automobile as much as that time. Nobody was killed or significantly injured because of the fires, however the automobile’s unlucky title and popularity led to Pontiac retiring the mannequin by 1988 and ultimately recalling each Fiero ever delivered.
So contemplating the unique automobile’s popularity, why would they select to do a Fiero conversion? “I had this actual automobile.” Explains Tim Bradley. “It was at the moment in my life the very best automobile I ever had. It had a candy spot in my coronary heart.” As time went on and Tim began a household, he needed to promote the tiny two-seater. However he all the time needed to be again behind the wheel of a Fiero once more. When he discovered a used, well-maintained instance with solely 14,000 miles on the odometer, he instantly jumped on it as a interest automobile. After driving it round for just a few years, he determined it might be the proper candidate for an EV conversion.
The conversion store started its construct in March of 2020 however was continuously halted because of the pandemic. In line with Nick, the staff solely spent about 180 days actively engaged on the mission, they had been unfold throughout two years. It took them a number of months simply to discover a donor automobile for the EV parts. They lastly accomplished the construct in 2022.
Contemplating all the additional energy and weight of the automobile, the brakes had been going to wish a serious improve as properly. “This can be a hydraulic brake booster that produces about 2,000 psi of hydraulic stress. It’s really from Speedway and is utilized in race vehicles.” Nick explains. The unique manufacturing unit brakes had been apparently “terrifying” to make use of after the improve. The regen braking additionally had points kicking in. “It’s a great various that produces sufficient stress for racing brakes.”
The construct is sort of clear and properly executed together with customized gages to match the unique look, a Tesla badge on the entrance, and “Electrical” spelled out on the rear gentle bar. So it’s a bit odd that they selected to retain the quad exhaust from the unique Fiero GT bundle. Seems they did this purely for aesthetic causes. “The GT is so recognized for the gorgeous quad-tips on the again of the automobile. And we took it off however there was this gaping gap. It didn’t look proper, it didn’t match.”
