Because the daybreak of the car, hustlers and dangerous actors have tried separating lovers from their cash by debuting flashy ideas, then soft-pedaling their launch indefinitely. That development has solely accelerated within the final decade with the development of digital design instruments, AI, and social media. 

Today, all it takes to gather orders for a brand new hypercar is a set of convincing renders and an Instagram deal with, with corporations you’ve by no means heard of peddling GTA-looking vehicles that will by no means see a highway not fabricated from pixels.

That’s not Praga’s MO. The Czech firm behind the two,200-pound, 700-horsepower Bohema is probably not well-known, however with over a decade of racing and growth underneath its belt, it’s adamant that its first manufacturing hypercar is as prepared for prime time as something from Ferrari, McLaren, or Lamborghini.

Talking with Motor1 on the Goodwood Pageant of Velocity, each the corporate’s chief engineer and its head of selling shared the Bohema’s growth historical past and defined the way it ended up being the primary non-Nissan to make use of the GT-R’s lauded twin-turbo V-6.

Although you most likely haven’t heard of it, Praga has been round in a single kind or one other since 1908. Through the Czech socialist interval lasting from the Forties via 1989, it produced agricultural automobiles and light-weight vehicles together with gearboxes and different parts underneath authorities orders. Because the early 2010s, although, its ambitions have targeted squarely on the racetrack.

Jan Martinek, Praga’s Chief Engineer, joined the group in 2013 with the project of creating the single-seat, carbon-tub R1 race automobile road-legal. The corporate noticed a market area of interest in an ultra-light observe day supercar, so Martinek constructed a prototype known as R1R and began taking it to circuits throughout Europe. As he tells it, folks beloved the automobile’s 700-kilogram weight, however had been skeptical of its cramped cabin, lack of air-con, and four-cylinder engine. 

Praga made its first PR splash again in 2016, courtesy of Swedish skier Jon Olsson. The corporate was on the lookout for traders, and Jon was a automobile fanatic with cash and a fame for daily-driving sports activities vehicles in all situations. 

“I texted Jon like, ‘Hey, would you be prepared to check drive the automobile for a bit bit in Monaco?’” Martinek recalled. Olsson did him one higher, asking to borrow the R1R to drive from Monaco to his residence in Marbella, Spain—a distance of over 1,200 miles in a full-blown race automobile.

Olsson featured the automobile in his vlog, apparently having fun with it a lot he requested to borrow it once more—this time for an ice race in Northern Sweden, one other 1,200 miles from residence in minus-24-degree climate. The prototype’s ECU froze as soon as within the chilly and needed to be warmed up, however aside from that hiccup, the R1R carried out flawlessly.

Round that point, Praga got here underneath new possession once more, and the corporate modified instructions with its roadgoing idea. Whereas the R1R had a “one-plus-one” seating configuration with a central driving place and a movable steering column to permit for a passenger, buyer suggestions dictated two full-size seats. Clients additionally demanded air-con and extra creature comforts than the bare-bones race automobile. 

Round that point, Aston Martin revealed the Valkyrie, beating Praga to the punch with a race automobile for the road. “That was the most effective factor that might have occurred,” Martinek stated. “Out of the blue, you had Mr. JWW moving into the seat and saying, ‘That is like an F1 [car].’ It normalized it.”

Constructing the Bohema

Praga spent the subsequent eight years growing and testing the Bohema. It jumped via regulatory hoops and tackled engineering challenges, corresponding to how one can design windshield wipers for its wraparound entrance glass, or how one can preserve the cabin as slender as potential for aerodynamics, whereas nonetheless giving driver and passenger loads of elbow room. (The answer for the latter is a intelligent staggered seating association that places the driving force’s elbow relaxation above and forward of the passenger’s.) 

However maybe essentially the most fascinating engineering debate was what engine the Bohema ought to have.

Praga is the primary firm to license Nissan’s 3.8-liter VR38DETT V-6, the center of the R35 GT-R. UK tuner Iain Litchfield then massages it to a steady 700 horsepower to be used within the Bohema. However the determination to go along with the V-6 didn’t come simply. 

“After we constructed the R1R [road-]authorized model, it was a four-cylinder turbo,” Martinek informed Motor1. “And after we had been contemplating manufacturing, I wished to eliminate the turbo due to warmth, plus higher sound, and all. So I wished [a] natural-powered V-6 as a result of it will be the identical energy, similar weight, however naturally-aspirated.”

Praga approached Nissan about supplying it with its VQ line of naturally-aspirated V-6s. Fairly rapidly, the Japanese firm agreed, however Martinek wasn’t completed.

I raised a query: ‘What if—simply what if—we’re contemplating some particular version. What concerning the GT-R engine?’

“I raised a query: ‘What if—simply what if—we’re contemplating some particular version. What concerning the GT-R engine?’” As Praga’s chief engineer recollects, the request was initially met with indignation: “‘No method, by no means. Crown jewel of Japan, we’ll by no means give this to anybody.’” 

As Praga’s idea shifted from the R1R to a two-seat, million-plus-dollar hypercar, a naturally-aspirated VQ wouldn’t reduce it. Praga went again to Nissan concerning the GT-R V-6 whereas approaching BMW, Mercedes, and Audi for engine choices, too.

Designed Round a V-10

Whereas the corporate awaited phrase from Nissan, Audi authorised Praga’s request for the R8’s 5.2-liter V-10. “That’s when Nissan got here again to us and stated, ‘We had a board assembly and determined we may provide the engine.’ So we purchased each of the engines,” Martinek stated. 

However as Praga debated the relative deserves of the 2 engines, it nonetheless had a automobile to design. Uncertain which method issues would go, the corporate engineered the Bohema’s carbon construction to accommodate the bigger V-10.

The automobile was designed across the V-10 as a result of then we knew that we may match the V-6 as nicely.

“We bodily had each engines,” Martinek defined. “So the automobile was designed across the V-10 as a result of then we knew that we may match the V-6 as nicely.”

We all know which course Praga went—however why forego naturally-aspirated V-10 screams in a hardcore, light-weight automobile? 

“Ultimately, it was emissions causes, it was the help we may get from Iain [Litchfield], but it surely was additionally the help we may get from the [OEM] factories.” Martinek additionally cited tunability as a key issue. “Sure, V-10 sounds higher on paper, [and] in sound,” he acknowledged. “However it’s 600 brake horsepower and that’s it. This [V-6] is a bulletproof engine and the facility—sky’s the restrict.”

Whenever you see it, you virtually anticipate [a] screaming V-10. It provides the automobile its personal distinctive character.

I requested Praga Gross sales & Advertising and marketing Director Mark Harrison whether or not clients had been delay by “solely” having a GT-R engine of their $1.5-million hypercar. On the contrary, he stated it hasn’t been a difficulty. 

“Everybody I spoke to within the US, once they stated ‘What’s the engine?’ And I informed them, they stated, ‘Nice. I’ve bought a GT-R as my day by day. It’s bombproof, it’s dependable, it’s one much less factor to fret about.’” Additionally, he added, “it’s unique, as a result of Nissan has by no means let anybody else take that engine.”

Martinek admits that the turbocharged coronary heart is a bit sudden given the Bohema’s radical appears—however that’s not essentially a nasty factor. “Whenever you see it, you virtually anticipate [a] screaming V-10,” he informed Motor1. “It provides the automobile its personal distinctive character.”
