The historic automotive firm Praga, at present a worldwide participant in numerous on- and off-track racing disciplines around the globe, revealed its all-new road-legal hypercar in pre-production prototype kind: a high-performance, low-volume, beautifully-appointed automotive designed round three core rules – light-weight, carbon, gasoline.

The brand new Praga Bohema is a sub-2,204 kilos, mid-engined two-seater that, in the suitable palms, is able to extraordinarily excessive efficiency on observe focusing on GT3 race automotive lap occasions on its semi-slick Pirellis. But it is usually snug and sensible for head-turning street journeys. With its carbon fiber monocoque and race-oriented totally adjustable suspension, this can be very mild, focusing on simply 2,164 lbs (moist with out gas), whereas its highly effective Nissan GT-R-derived six-cylinder twin-turbo engine ensures reliability, ease of servicing, and the potential for additional efficiency tuning. Whereas the Bohema’s race-derived semi-automatic transmission will assist a singular on-road expertise with track-focused efficiency.

The purpose? That the Bohema is a uniquely styled, uncommon, and unique automotive that you just actually can drive to the observe, pull on a crash helmet (taken from the bespoke baggage fitted in every of the automotive’s revolutionary 13.2 US gallon facet pods), put in lap after lap at excessive pace on its Pirelli Trofeo R tires, after which drive house once more. The inspiration? Longstanding Praga pal and ambassador, and former F1 and present IndyCar driver, Romain Grosjean challenged Praga to ship a real uncompromised two-person street/observe efficiency automotive, promising a really distinctive driver expertise. He was subsequently concerned within the Bohema challenge and highlighted the automotive’s seamless transition from street to trace whereas delivering in depth periods on the difficult 3.7-mile Slovakia Ring circuit in current testing.

“I used to be astonished by the Bohema’s superb efficiency on observe, its accessibility on street, and the convenience of transition between the 2,” mentioned Romain. “Praga really delivered on my problem! On the street, you get a clean journey, the automotive eliminates the bumps, you possibly can chat with the passenger, and every little thing is calm and OK. Then merely swap focus and you’re on the observe. The identical garments, the identical automotive, however the feeling modifications and you’re pushing the restrict and amassing superb lap occasions time and again, discovering unbelievable prospects within the Bohema. And we nonetheless have a couple of months to fine-tune the on-road compliance and on-track lap occasions!”

The consequence? The Bohema is an all-new design, developed by Praga’s small, however proficient workforce of engineers and designers, and perfected in an F1 workforce’s wind tunnel. It makes use of a race-derived carbon fiber monocoque, with in depth aero offering over 1,984 lbs of downforce at 155 mph. Prime pace is simply over 186 mph: the quickest pace achievable on nearly any racetrack. Crucially, the automotive’s aerodynamically-inspired engineering didn’t get rid of elegant and intriguing designed bodywork to make sure the automotive appears to be like quick, and appears good. Top quality machined Praga Gold painted duraluminum particulars embrace door hinges and a tow hook that includes an built-in rear-facing digital camera that stand out on the Praga blue present automotive and replicate Praga’s consideration to element. The Bohema is that rarest of vehicles with the ‘wow’ consider each appears to be like and efficiency.

In contrast to many racetrack-derived efficiency vehicles, the Bohema’s ingenious inside ergonomics delivers a slim, aerodynamically honed cockpit but seats two, 6.5-feet-tall adults with totally adjustable driver’s seat, steering wheel and pedals, beneficiant baggage area, aircon and helpful rear visibility. All at lower than 2,204 lbs. Praga’s obsession with its sub-2,204 kilos goal weight is highlighted by the Bohema’s cockpit statistics: structurally designed with 56 particular person carbon components, and trimmed with high-quality Alcantara and leather-based, the cockpit’s goal weight is simply 74.9 lbs. The give attention to protecting the Bohema beneath 2,204 lbs is demonstrated by Praga’s outstanding consideration to element in each side of the design, with in depth use manufactured from carbon fiber, magnesium alloys and titanium.

Its unbiased suspension makes use of pushrod-operated adjustable dampers mounted horizontally for max journey whereas minimizing bodywork top. In such a light-weight automotive, with simply 396.8 lbs of unsprung mass, Praga’s growth engineers had been nonetheless capable of maintain the suspension supple sufficient for street use with out having to resort to costly adaptive suspension programs. The central-locked wheels are 18in diameter on the entrance and 19in on the rear to supply on-road compliance by way of their giant tire partitions, however the Bohema will settle for 18in wheels all-round, which ensures compatibility with the FIA GT3 spec tire dimension – the race tire with the widest potential vary of competitors tires globally. The highly effective brakes use light-weight however sturdy 380 mm carbon ceramic discs with six-piston calipers.

The Praga Bohema is coming into the ultimate few months of growth with street and observe packages deliberate within the UK, Europe, and the Center East and on the Slovakia Ring house circuit. Manufacturing of the $1.31m (+ taxes) hypercar is scheduled to start within the Czech Republic within the second half of 2023, with simply 10 vehicles initially scheduled for 2023 manufacturing. A world consumer customer and spec’ing headquarters may also be established in England in 2023, constructing on Praga’s rising race program within the UK. Roughly 20 vehicles per 12 months might be hand-built over the next 4 years guaranteeing exclusivity for homeowners, and Praga plans to supply observe handover packages with its skilled test-driver lineup for homeowners to make sure that the total efficiency and capabilities of the Bohema are understood and accessible.

Praga Bohema intimately

Powertrain
The Praga Bohema’s PL38DETT relies on Nissan’s famed 3.8-liter, twin-turbo V6 engine utilized in all its GT-R fashions since 2007. Initially drawing on Nissan’s expertise at Le Mans, it’s constructed round an aluminum alloy cylinder block, and there are double overhead camshafts per cylinder financial institution, with a constantly variable valve timing system on the inlet valves. The great thing about this engine isn’t just its sheer efficiency potential, but in addition its famend reliability and tunability.

Uniquely, Nissan provides model new GT-R engines to Praga for the Bohema. Engine growth and servicing necessities then sees Praga working with the UK’s famend Litchfield Engineering; one other long-time pal of the Praga model. Litchfield has greater than twenty years of tuning expertise and is called the worldwide authority on GT-R engines. Litchfield strips the brand new engines and converts them to dry sump, which reduces the general top of the unit by 5.51 in. This enables the engine to take a seat decrease within the Bohema and prevents the dangers of oil surge beneath high-speed cornering hundreds.

Litchfield additionally makes quite a lot of modifications for elevated reliability and energy, together with swapping to new twin turbos. On this base-Litchfield specification, Praga is focusing on the Bohema manufacturing automotive to ship as much as 700 bhp at 6,800 rpm and 534 lb ft of torque from 3,000 to six,000 rpm, however Litchfield is thought for constructing 1,000 bhp-plus engines from the GT-R unit. The engine breathes out by way of exhausts which might be titanium proper from the turbos to the tailpipes, with a lot of the silencing supplied by the catalytic convertors, giving a pointy crackle to the engine be aware whereas remaining inside typical circuit noise limits – and guaranteeing that occupants can nonetheless maintain a dialog even at nicely over authorized street pace limits.

The Bohema’s engine is mated to the famend Hewland sequential gearbox by way of a robotic clutch permitting for semi-automatic drive mode. This alternative of gearbox, geared up with bespoke road-optimized helical minimize gears, ensures fast-changing, sturdiness and skill to deal with excessive torque at a minimal weight. In basic race automotive and supercar model, the engine sits immediately behind the cockpit, with the transmission behind the engine driving the rear wheels, for optimum weight stability and responsiveness in turns. Crucially, the engine and gearbox are independently mounted from the carbon chassis guaranteeing annoying and loud sub-woofer model resonance and vibrations should not transferred by way of to the cockpit from the engine bay. A 19.5-US gallon gas tank ensures street journeys could be accomplished with minimal fuss.

Chassis and bodywork
The Bohema was designed and styled fully in-house by the Praga workforce, utilizing CFD (computational fluid dynamics) modeling adopted by fine-tuning in an F1 workforce’s wind tunnel. Engineers and designers labored as one, to make sure all surfaces look thrilling and chic but stay uncompromised of their contribution to aerodynamic effectivity and efficiency. It’s undiluted kind and performance in concord. It makes use of in depth and revolutionary aerodynamics, together with a singular rear spoiler design which, mixed, ends in over 1,984 lbs of downforce at 155 mph. The chassis is an especially sturdy, torsionally inflexible carbon fiber monocoque development: in fashionable occasions, Praga has solely ever designed and constructed all-carbon race vehicles, benefiting from the expertise and native experience in carbon fiber manufacturing within the Czech Republic and Slovakia employed by lots of Europe’s main luxurious automotive manufacturers.

The light-weight carbon fiber outer panels are connected to the monocoque. The entrance high panel covers the suspension, with refined bulges to accommodate the horizontal dampers. On the rear, a single panel covers the engine, transmission and suspension. The entrance wings should not structural, so the entrance mirrors are mounted on lengthy inflexible stalks to supply fashionable and aerodynamic constructions with glorious rear imaginative and prescient with out vibration or obstruction. Throughout the aerodynamically styled rear wheel arches there are deep storage areas, for which custom-fit leather-based baggage is obtainable – sufficiently big for a crash helmet, racing go well with and boots, or an informal weekend bag. The doorways are entrance hinged and electronically launched, with backup mechanical releases. The deeply curved trademark Praga windscreen ensures outstanding visibility contained in the cockpit, and is swept clear by an ingenious mechanism specifically developed by Praga to make sure that the windscreen wiper stays involved with the glass throughout its full width.

Cockpit
With the race-derived carbon fiber monocoque, the cockpit is essentially slim however cleverly formed to completely match two giant adults in race-position consolation. The doorways swing open giving entry over the bodywork into the cockpit, with steps constructed into the footwells to permit driver and passenger to decrease themselves into their seats with out having to step onto the seats themselves. Moreover, the steering wheel is detachable to help entry and exit. The driving place could be completely tailor-made with adjustable steering column, pedal field, and seat place and angle. The ergonomically sculpted construction additionally incorporates molded recesses for the passenger’s arms and elbows to make sure consolation with out infringing on the motive force’s area – quite a lot of effort was made to make sure an ideal driver’s setting.

The detachable steering wheel in itself is a murals. It incorporates a big digital show, displaying pace, gear chosen, oil and coolant temperatures, driving mode and warning lights. To both facet is a switchgear for indicators, horn and additional capabilities, plus rotary thumbwheel selectors. The rim is fantastically trimmed in Alcantara and the central pad is roofed in leather-based with an embossed Praga brand. The grip and paddles’ measurement and positioning had been designed completely to supply steering and shift management comfortably for small and large-handed drivers alike.

Simply to the facet of the steering wheel, within the slim heart console, are additional controls together with launch management, in-built hearth extinguisher set off and the digital parking brake. To both facet of the cockpit are the digital door releases (supplemented by mechanical releases within the roof) plus mirror controls, whereas the aircon controls are mounted in a trendy ‘fighter jet’ model roof console: Praga’s design workforce taking inspiration from the corporate’s aviation and race automotive divisions.

An ingenious and hidden sprung-mount bracket above the middle console permits a smartphone to be securely mounted to be used as a satnav and efficiency knowledge monitor. There are storage pockets within the doorways and behind the seats to make sure bottles and oddments could be safely stashed out of the best way. Whereas every little thing within the cockpit is designed to contribute to the automotive’s low weight goal and performance, the aesthetics and a spotlight to element weren’t ignored – the fantastically machined thumbwheels and air vents, the ending of the inside carbon fiber, and the beautiful hand stitching of the Alcantara are excellent examples.
