While commuter automobiles and small tuners might come to thoughts when discussing three-cylinder engines, just a few manufacturers choose to see simply how far trendy efficiency tech and engineering will permit the small engine to go. This has led to turbocharged and race-tuned three-cylinders finding a home in today’s sports cars. However, there ar sure manufacturers that select to develop upon the superior parts accessible to create an indomitable automobile that gives a glimpse into the way forward for efficiency and effectivity.Koenigsegg, a well known Swedish efficiency model, is revered for creating some of the world’s fastest, most advanced vehicles, usually dubbed hypercars or supercars. While within the firm of different unique manufacturers, together with Lamborghini and McLaren, Koenigsegg manages to face out because of the exclusivity and creativity of each mannequin. These fashions embrace the Regera, Jesko Attack, and One:1, to call just a few icons.More curiously, they’ve created a novel system that extracts a whopping 600 horsepower and 443 pound-feet of torque out of a small three-cylinder engine. Though this can be noteworthy by itself, there may be extra to the story that makes this explicit engine, and the automobile that homes it, a really intriguing automobile, to say the least. Superior tech and next-level engineering have allowed Koenigsegg to safe the “world’s most powerful” title within the three-cylinder class. What they did subsequent can solely be described as ludicrous.

The Worlds Most Powerful Three Pot Is Aided By An Ingenious E-Tri-Motor System

To begin, the Koenigsegg’s three-cylinder engine, often called the TFG (tiny pleasant big), is, by itself, the world’s strongest three-cylinder mill and is discovered within the stunning Gemera mannequin. Though it would not actually be a supercar mill with out some spectacular stats, which is the place the engineering and automotive developments enter the story. Surrounding the three-cylinder TFG are two Koenigsegg, in-house designed Dark matter e-motors that ship energy to the rear wheels by way of a single-speed gearbox, every good for 500 horses and 738 pound-feet of torque. If we preserve depend of the horsepower, that is a mixed 1,600 horsepower. But wait, there’s extra!Located on the finish of the TFG’s crankshaft sits one other Dark Matter electrical motor that produces a further 400 horsepower and 369 pound-feet of torque. The third motor and three-cylinder engine ship energy to the entrance wheels solely, granting the Gemera the title of Koenigsegg’s first all-wheel drive automobile. We’re now at a mixed 2,000 horsepower and a couple of,288 pound-feet of torque. Suffice to say, this setup is among the many strongest in any road-going automobile so far, and is unquestionably probably the most highly effective with three cylinders.The TFG additionally grabs the title for many highly effective 2.0-liter engine in manufacturing. This is little question attributed to its massive bore and stroke, that are 95mm and 93.5mm respectively. The Gemera’s cylinders are literally bigger than Koenigsegg’s 5.0-liter V-8, dealing with 200 horsepower per cylinder because of the massive displacement. That’s 2.5-times greater than the following highest rated three-cylinder.

The Gemera’s Real-World Numbers

The Koenigsegg Gemera is likely one of the firm’s quickest fashions. It additionally holds the title as the corporate’s first all-wheel drive mannequin because of the tri-motor setup and the way it powers the axles. The wild horsepower numbers are insane on paper and in actual life, although they fluctuate due to a couple components. The official output of the Koenigsegg Gemera is rated at 1,700 horsepower. This is as a result of battery’s output energy restrict in addition to the person motors’ and engine’s various peak instances.

(Source: Koenigsegg)This muzzling of the horsepower permits the automobile to attain a extra cheap sense of management. However, it would not stifle the efficiency in any manner. If something, Koenigsegg has achieved a really particular recipe for the insanely highly effective setup that enables it to shine greater than if it have been a 2,000 horsepower freak of nature. Not to say, the Gemera is a street-legal “family” car that seats four passengers. The added torque could be attributed to the hydraulic coupling positioned on the torque converter, which Koenigsegg says permits as much as two-times wheel torque multiplication as much as 3,000 rpm.

Turbocharger? The TFG Has Two

While the e-tri-motor setup produces spectacular energy, the star of the present is the three pot kicking out 600 horses by itself. To illustrate, Mercedes holds the title for many highly effective four-cylinder, with their 416 horsepower M139. Not solely is the Koenigsegg TFG extra highly effective, however it could obtain this feat with out the help of its e-tri-motor system and with one much less cylinder.This is because of the distinctive twin-turbo setup discovered within the engine bay. You’ll hear me use the phrase “unique” when describing the ins-and-outs of the TFG setup. This is as a result of it merely is not a broadly used know-how or design, so all the pieces concerned is, in reality, distinctive at its core. The twin-turbo system makes use of a low-rpm turbo that handles revs under 1,700 rpm, and a high-rpm turbo that begins to spool up increase from 2,000 rpm as much as 7,000 rpm. This is just like a sequential or staged turbo system in that it gives extra increase because the engine revs larger. Combined, the twin-turbo system produces 29 PSI of increase.

Koenigsegg’s FreeValve Technology And Other Features May Revolutionize The Automotive Industry

Some of you’ll have heard of FreeValve technology when researching high-performance automobiles, although few are conversant in the method and the way it revolutionizes valve tech. FreeValve, put merely, makes use of electro-hydraulic pneumatic management as an alternative of a camshaft to ship final valve variability and management. This permits the automobile to manage the valve timing, raise, and length, which makes for extremely versatile energy supply. It additionally permits the three-cylinder TFG to simply run the Atkinson cycle and deactivate cylinders at will.Pneumatic actuators permit the valve to open, maintain its place, then shut based mostly on the meant efficiency aim. This can lead to the piston shifting extraordinarily quick with optimum airflow by attaining peak valve raise earlier and for longer durations than a conventional camshaft profile might permit. The TFG makes final use of this method with three-cylinders pumping out optimum energy and effectivity almost continuous. FreeValve know-how provides just a few key advantages, together with elevated gas economic system and emission discount.

Key Benefits Of FreeValve Technology

• Increased gas economic system
• Increased Torque
• Increased Power
• Decreased gas emissions
• Lighter weight

While this can be a revolutionary system that would advance the automotive world at massive, it’s a subtle, and costly, system to construct and implement. Not to say, additional testing can be required to totally approve the FreeValve tech for widespread use. However, corporations like Qoros have been experimenting with pneumatic variable valve tech in hopes that sooner or later mass manufacturing will probably be potential, even revealing an idea of the mission in 2016.

The Gemera’s Sophisticated Torque Vectoring

The all-wheel drive system features a absolutely unbiased moist clutch in any respect 4 wheels that may lock up and disconnect each time wanted, offering the Gemera with very good torque vectoring and traction. This additionally permits the three-cylinder TFG to carry out effectively in high-speed cornering and slippery street circumstances. Being as every wheel and clutch meeting works independently, you possibly can function in front-wheel drive mode or all-wheel drive. Rear-wheel drive is unavailable, as the first inner combustion engine and motor duo energy the entrance wheels solely.

The Significance Of Koenigsegg’s 600 Horsepower Three-Cylinder Engine

The Swedish automaker’s willingness to show the automotive establishment on its head is daring, to say the least, as their developments might set a extremely aggressive precedent amongst extra courses of car aside from high-performance automobiles. We’ve noticed turbocharged, twin-turbocharged, and naturally aspirated three-pots, however none on the stage of energy and class just like the TFG.Taking into consideration that the TFG is a bored-out twin-turbo three-cylinder hybrid, one can not help however surprise: what might Koenigsegg do with a V-6 or V-8 using an analogous energy construction? Regardless of the reply, they will stay within the headlines for now, coasting off the extremely revolutionary creation that’s the Tiny Friendly Giant. And we’ll stay awe-struck with the magnificence and ingenuity of the Koegnigsegg brand and their iconic products.
