This classic Firebird restomod swallowed a Prius

It takes an unusual eye to look at a 1967 Pontiac Firebird and see the Toyota Prius hidden inside. But that's just the kind of eye that a creative mechanic known online as "Bill the Engineer" has. Bill is updating his old Firebird into a true classic for the 21st century and has documenting the changes over at Priuschat and EcoModder. The TL,DR version of the story: he's replacing the worn-out powertrain with the gas-electric hybrid one from a Prius V, because it turns out the two vehicles have almost exactly the same wheelbase. Bill, who's from Columbus, Ohio and doesn't want his full name used, said in his posts on the conversion project that he's made many memories with this vehicle since buying it back in 1979. Since then, a few moves, a few decades, and some time in storage meant that the car would no longer function as he wanted it to. As he wrote, "when it comes to mice in the vehicles IT IS WAR." His solution is to make new memories and making a greener vehicle, and so we wanted to ask him how things have been going. Bill's been traveling a bit recently, but told AutoblogGreen that he's now figuring out the next steps for this amazing and complicated project. "I always plan things out before I do them," he said. That's the only way something like this can work. ABG: I think we have to start with what gave you the inspiration for this project. Was it simply that you had the two cars and wanted to see them merged into one cool mashup, or was it something else? "One day my wife wondered out loud if the car could be converted into a hybrid... The rest is history." Bill: I have been the owner of my 1967 Firebird convertible since 1979 when I bought it for $750.00. I drove it for years and made many memories. Afterward it was in storage for many years during which time mice at their way into the car and trashed the interior and wiring. I started working on a conventional restoration but always ran into major problems with hidden corrosion, electrical issues and an engine on its last legs. The car was never going to be as nice as I wanted going the conventional route. One day my wife wondered out loud if the car could be converted into a hybrid like our two daily driver Prii. That got me thinking about how it could be done. The rest is history... ABG: It looks like you started in late 2014. Have things gone well since then, or has it been one hassle after another? What has been the biggest setback, and what were the biggest victories?

Junkyard Gem: 1997 Pontiac Sunfire SE Convertible

For the entire 24-year production run of the GM J platform (best known for the Chevrolet Cavalier), the Pontiac Division offered new J-Body cars for sale in the United States. First there was the J2000, followed in quick succession by the 2000, 2000 Sunbird and Sunbird. The Sunbird stuck around until the Cavalier got a major redesign for the 1995 model year, at which point Pontiac changed the car's name to Sunfire. Today's Junkyard Gem is one of those early Sunfires, a top-of-the-line SE convertible with the optional big engine and manual transmission. The Sunfire was an extremely close sibling to the same-year Cavalier (by the late 1980s, all the other US-market GM divisions had dropped their J-cars, which meant no more Skyhawks, Cimarrons or Firenzas), quite difficult to distinguish from its near-twin at a glance. The base engine for the 1997 Sunfire convertible was the pushrod 2.2-liter straight-four that powered so many J-bodies of the 1990s. That engine produced just 120 gnashing, valve-floating horsepower, not much by late-1990s standards. For a mere 450 additional dollars, however, the 2.4-liter Twin Cam engine and its high-revving 150 horses could be had by '97 Sunfire buyers. That's what's in this car. This is one of the members of the Oldsmobile Quad 4 family, though some fanatics will yell at you if you apply that name to the versions that don't have big QUAD 4 lettering cast into the valve cover. This is the most powerful engine ever used in production Sunfires. For 1997, Pontiac offered a four-speed automatic transmission for no extra cost in the Sunfire convertible. Buyers of all other Sunfire models that year had to shell out either $550 or $810 ($1,026 or $1,511 in 2023 dollars) for a two-pedal rig. That means that the buyer of this car really wanted the five-speed manual transmission (or just hungered for the $810 credit offered in the fine print for takers of the manual). Plenty of free-breathing engine power, five-on-the-floor driving enjoyment and the open skies above. What a fun car! This one made it to nearly 180,000 miles. For this car with the Quad 4 under the hood and a clutch pedal on the floor, the MSRP was $18,539 (about $34,584 today). Its Cavalier LS convertible twin with the same engine/transmission setup cost $17,365 ($32,394 now). This car has a bunch of options, including the 15" Rally aluminum wheels, so the out-the-door price would have been higher. The last year for the Sunfire was 2005, same as the Cavalier.

Junkyard Gem: 1986 Pontiac Fiero GT

If you like affordable, mid-engined two-seaters, the 1980s were your decade. Fiat (and, a bit later, Bertone) offered the X1/9, Toyota sold MR2s, and even General Motors got into the act by creating the Fiero. Available from the 1984 through 1988 model years, the Pontiac Fiero showed plenty of promise but ended up being mostly disappointing, in some ways echoing the career of the Chevy Corvair of a couple of decades earlier. Today's Junkyard Gem is a once-spiffy 1986 Fiero GT, found in a self-service yard near Denver, Colorado. After a long and painful development period stretching all the way back to John DeLorean's XP-833 Banshee (which ended up being a major influence behind the original Opel GT), the Fiero finally debuted in 1983 as a 1984 model. The top-of-the-model-range GT appeared the following year. The Fiero was built as a notchback coupe and as a fastback, with all the GTs being the latter type. I couldn't get the engine lid open, but this car would have left the assembly line (in Pontiac, Michigan) with a 2.8-liter V6 rated at 140 horsepower. This car has a five-speed manual transmission, making it a credible rival for Toyota's MR2.  The 1986 MR2 was less powerful than the Fiero GT (112 horsepower versus 140), but also scaled in significantly lighter (2,459 pounds against the Pontiac's 2,780 pounds). The MR2 also cost less, priced at $11,298 while the Fiero GT cost $12,875 (that's about $30,540 and $34,805, respectively, in inflation-adjusted 2022 dollars). Meanwhile, the $6,998 Honda Civic CRX two-seater lured away many potential Fiero buyers despite being a front-engined/front-wheel-drive car, and the $7,186 Ford EXP/Mercury LN7 also put a dent in Fiero sales. I can't find a price for the 1986 Bertone X1/9, but it cost a hard-to-believe $13,990 in 1984. GM still was using five-digit odometers in many vehicles by the middle 1980s, but this Fiero has a six-digit unit and thus we can see that it nearly achieved 150,000 miles during its driving career. The 1984-1987 Fiero suffered from a parts-bin suspension design, with the front suspension borrowed from the Chevrolet Chevette and the entire rear transaxle/suspension assembly lifted from the front end of the Chevrolet Citation. For the 1988 model year, GM finally spent the money to design an improved Fiero-specific suspension … and then promptly put a halt to production.
