Nashville man who made world's thinnest road-legal car has now turned a tiny Ford Festiva into a bizarre 10-foot-wide highway monster

Most people modify their cars to make them faster or more powerful, but one Nashville man has a rather different approach to automotive engineering and turned a Ford Festiva into a bizarre highway monster.

Tyler Fever, the creator behind YouTube channel Prop Department, previously turned a tiny Ford Festiva into an incredibly thin road-legal car by slicing it down the middle.

Now, he has gone in the complete opposite direction, transforming another little hatchback into a gigantic yellow machine measuring a ridiculous 10 feet wide.

And somehow, this thing actually drives.

The creator behind the world’s thinnest car

Fever previously made headlines after turning a Ford Festiva into one of the world’s thinnest street-legal cars.

But apparently, making a car as small as possible wasn’t enough, because his latest project takes the same basic idea and stretches it to the extreme.

“I built the widest street legal car, and it’s the funnest thing ever to drive around town,” Fever said in his latest YouTube video.

He picked up several additional Ford Festivas for just $200 to $250 each, planning to use them as donor vehicles for the ambitious build.

The idea was simple: cut the original car directly down the middle, pull the two halves apart and fill the enormous gap with a custom-built structure.

After stripping the car down and using a handheld fiber laser to cut through its body, Fever settled on a final width of 10 feet.

That’s considerably wider than a typical passenger car, so the team had to reinforce the structure with steel, modify the suspension and extend various components to make everything fit.

The result looks like two tiny hatchbacks have been welded together, creating a car with enough cabin space to make a regular Ford Festiva feel positively cramped.

The bizarre highway monster is surprisingly road-ready

Turning the oversized hatchback into something resembling a finished car required plenty of welding, sanding and body filler, followed by a bright yellow paint job.

The team also created a custom eight-foot-wide grille and an enormous dashboard using 3D-printed components.

Inside, there’s so much room that the team joked about installing a bed, television and chandelier.

There’s even a second steering wheel, which makes sharing driving duties a little confusing.

One of the biggest engineering challenges was extending a CV axle by five feet to accommodate the extra width.

Fever built the custom component himself, carefully welding it together and using a jig to help keep the shaft straight.

Once installed, the car was finally ready for testing, although its first drives weren’t entirely smooth.

The team accidentally drove into a ditch, and the hood flew open during a speed test, but thankfully, the damage was minor, and they fitted a stronger hood latch before heading out again.

Getting the car onto public roads also required special paperwork.

“So in order to get it street legal, I had to get commercial insurance and an actual wide load permit,” Fever explained.

The team eventually took the enormous hatchback on a road trip spanning more than 400 miles, stopping at Buc-ee’s along the way.

The 10-foot-wide Ford Festiva turns heads on the highway

With 14 extra-large cup holders and enough space to haul groceries, the highway monster proved surprisingly practical, although navigating traffic and tight spaces was another story.

The team even loaded chickens into the back, only to discover that their new passengers weren’t particularly pleasant company, and even the local police had their say.

After turning a tiny Ford Festiva into one of the skinniest cars around, Fever has now created something at the opposite end of the spectrum.

And while we’re not convinced a 10-foot-wide highway monster is the answer to traffic, it’s certainly one way to make sure nobody parks too close to you.
